[email protected] GT3071R .63

[KrazyZenki]

The car is finally tuned. [email protected] and [email protected] The car has more in it I think because he stopped the pull around 6800rpms because the alternator was messing up and we never did another power pull. Heres a quick mod list:

S13 SR20DET
GT3071R .63
Custom Top mount manifold
GReddy intake manifold
GM 3 bar map sensor
AEM EMS
AEM Wideband
Brian Crower 264s


Dyno graph coming soon

[Flybert]

When did you make full boost in the 19psi run?

[wootwoot]

if you only went to 6800rpms, ofcourse you have more power. Where is the proof/detail though?

[zoototheyork]

what about internals? stock?

[GSXRJJordan]

all good questions - first off, great numbers! 13psi is a great street boost level, and 366 on the street is fantastic for an SR! When you did cams, I'm assuming you did springs/retainers/gears? And what about the bottom end? And who tuned it? We'll definitely need that graph too =P

WHAT HAVE I BEEN SAYING ABOUT THIS SETUP PEOPLE!

Throw your internals in the trash and go top mount and use this turbo.

It's the sht, I just get more and more proof of the pudding everyday reading awesome posts like ths.

good job man. excellent selection.

[KrazyZenki]

When did you make full boost in the 19psi run?

Not sure it looks like before 4k, they have a feature on the dyno that tells me when i hit it Ill have to go down there and check.

if you only went to 6800rpms, ofcourse you have more power. Where is the proof/detail though?


Well Ill have to get it back on the dyno to see how much more power it will make after 6800. Im hoping to get the dyno graph emailed to me tonight.


what about internals? stock?

yup all stock bottom end. ARP headstuds, apexi hg

Thanks. I did GReddy valvesprings and RAS. Im putting BC ti retainers and springs in it in a couple of weeks. Bottom end is stock. Jay Healy from Carter Raacing tuned the car. Great tuner. Im hoping to have the graph posted up soon.

[projectdrifter]

that is very stout numbers for a 19 psi car. were u shooting 4 a certin psi and never made it or where u after a certin powerband and a got what u were looking for?
was that pump gas or 110?
its a very simple setup very good numbers congrats

[steve shadows]

Crower's cams are bigger lift than HKS, more air per stroke...

It makes a difference.

That and the numbers might be corrected (from the dyno).

Either way its right on target for what I would have predicted.

This is a equation for 400 hp, people should be taking notes now that their is some more evidence...once the dyno graph gets posted of course.

[projectdrifter]

i wonder what spec crower cams he has. id assume the 262 drop in cams because the v3 272 12.5 lift require the spring/retainers when u install them.

[steve shadows]

yeah I hope hes running the big ones, otherwise I think the numbers are uncorrected or sometihng...that is a little on the high side, would make more sense wtih gt3076R.

[white97s14]

damn nice numbers im hoping to be putting numbers close to that down with my setup

[j20accord00]

im selling my 2871r and getting a 3071r lol...nice numbers

[MavericStephenc]

do you think there would be much change from top mount to bottom in terms of power other than i'm using a gt3071r with a .86 arwith a 90trim turbine and t25 housing

[chrisman2k]

:bowdown: Stock bottom end, cams, and the manifolds.... my goal of 400 wheel is easier to do then I thought! I am still putting together my parts list for the shop, and now the list just got way shorter for the motor build. Post your chart, I want to see how streetable it is.

[slow40]

i don't know sr's...but how long will those piston rings hold up?? a buddy of mine blew his on 330 whp, that seems like alotta boost on stock internals...i'd like to know how long he plans to keep it stock...to me it doesn't matter how much power you make on a few dyno runs.. it's how long you keep making power...my 2 cents anyway

[projectdrifter]

im shooting in the dark hear. but id assume he has the 262 lift cams,arp studs, a 1.2mm apexi/cometic/ect/ect head gasket,ras he stated above that he has stock valve train. im going with a uncorected dyno pull. still a quick street car and depending on if he has a lsd and sticky tires could potentally put a ws6 or c5 vet down at the track. taking weight/power ration into account.

as for trading up from a gt2871. 64ar look under cody ace his recipie for 400whp. he has nothing to hide his list is out there and dyno graph. i can tell u from personal experiance and getting a few ride alongs his setup is no joke. he has made highly modded ws6 spraying play the catch up game.

[steve shadows]

its poop

go top mount and external for consitancy and ease of tuning + heat.

I wanted to stop the psi at 19 because scott enthalpy recommends that to be the highest boost to use on the street to be safe and avoid detonation. Now my buddies run 22-23 psi on pump gas with no problems but scott is scott so ill trust his opinion.

i wonder what spec crower cams he has. id assume the 262 drop in cams because the v3 272 12.5 lift require the spring/retainers when u install them.

I have the 264s. I also have the springs and retainers waiting to be installed. I chose the 264s because I wanted response which they do but they also have a nasty topend. Probably alot to do with the GReddy intake manifold.

yeah I hope hes running the big ones, otherwise I think the numbers are uncorrected or sometihng...that is a little on the high side, would make more sense wtih gt3076R.

Nope got the small ones. Not corrected. The tuner Jay Healy has set many records when it comes to tuning as far as making more power setup to setup. I also dont have a production exhaust manifold. It an equal length top mount with 15-16inch runners. Almost a straight drag manifold.

do you think there would be much change from top mount to bottom in terms of power other than i'm using a gt3071r with a .86 arwith a 90trim turbine and t25 housing

the t25 housing is going to be holding you back alot. Id say go top mount with a t3 backside.

Im trying to get the dyno chart waiting for the shop to email it to me. I have the paper but no scanner.

I know what your saying. Its made it through 120 dyno pulls. The bottem end should hold up for awhile because I only drive it around on 13psi. I got a little scare though the oil strainer broke off and caused a build in crankcase pressure which gave me a lot of blowby. Good thing enjuku racing makes a reinforced one so I can avoid this in the future.

Your right 264s, apexi hg, arp studs, ras, but i have full brian crower top end ready to be installed in the next couple of weeks. Im sure ill lay a few ws6s and vette down at the track. I have a cusco 1.5 and drag radials coming soon but i need subframe conectors and spacrs to get rid of the wheel hop. Alot of my buddies have TAs and vettes so its funny you say that. My buddy is making 412rwhp in his kat s13 and he was dead even with an 06 z06 from a 2nd gear roll all the way up to 120ish.

very sweet man i thought i seen your car in the image thread very clean car. best of luck in ur next steps to taking it to the next level. i would recomend a meth/water injection kit 4 safety with stock bottom end. it will reduce the intake temps and detonation properties. and im sure pick you up a few ponies as well. keep us posted

Just your 2 cents anyways.

In this case, 2 cents is WORTHLESS.

The ability for a combustion chamber to maintain life is directly equal to The temperature is operates in, and the ammount of detonation it sees.

I am guessing your friends had horrid Engine management systems.

Because, those to factors, and directly equal to the air/fuel ratio (cylinder temps) and the ignition timing (detonation).

If the tunner he broght it to was worth ANYTHING, which it sounds like he is, because you dont just stumble over 400whp on pump gas, im thinking he should be just fine.

BTW, I am :wackit: right now, waiting for your dyno graph, same turbo i will be using on my 2.2. OMG so f-ing hot.

thats my boy cody... that car is stupid quick and dosnt feel it the turbo comes in so liniar. almost like a high whp na setup. he is located in pa, the poconos.

u will deffantly have lag with a gt30 top mount but u will have hella top end where the gt28 dosnt flow as well. it still flows dont get me wrong. i would like 2 see cody ace setup with the bigger ar housing and a meth kit possible a 450whp+ setup on a safe tune

yea im a friend. i grew up with him i moved 2 sc about 3 years ago. i go up every few months to chill and what not. that car is fast and u never know it. he has pulled ws6 spraying because of how fast it in in the 60 foot. they play catch up but the car keeps rolling. simple yet effective tried and true.

sounds good to me... do you kno what FMIC he had during that dyno/setup? i e-mailed him like 4 days ago.. but nothing back yet.

[KrazyZenki]

I am really thinking of copying his setup in my next car. This car was supposed to be my road race car but I think it might turn into a drag car. The custom manifold wont allow for power steering, long runners more for top end, so it might just be the drag car and the next sr I do Im thinking copying cody's setup. If I decide to go drag with this car, it will get forged internals, 272s, and nitrous. 25psi+ some nitrous will get me 600rwhp+ :)

[boostin13b]

Looks like some killer numbers, I'm interested to know which 3071 your running. I've seen a few different makes and models. Everything from a 56.5 mm wheel to a 60 mm wheel. 4" inlet or 2.75". The power looks like your running the larger wheel, but if your spool time is what you say it is, I would think your running the smaller wheel, which would be very impressive.

I'm itching to get to the dyno with the wifes car running an SC34, which I've run on a few hondas with very good results. I'm hoping to see comparable numbers to your setup, with just a couple more PSI. HKS 264/272's, pistons, rods, ported head, valvetrain, AEM EMS.

I definately want to see your dyno.

[KrazyZenki]

Im running the Garret 3071R .63a/r with the 2.75" inlet. Its the 56mm wheel from what I understand. Like I said I think alot of the power has to due with the custom manifold and brian crower cams.

i've heard bad things about SR tranny's past 500+rwhp in dragging...?
heard some ppl use the 300zx TT 5spd. with some adapter kit?

just what i heard tho

[KrazyZenki]

I heard the same thing if I run into that Ill go with the Z32, peak performance dog box or the ppg gear set. I would love the ppg gear set because they make a nice whining noise. Some people dont like it but I think it sound awesome.

[GSXRJJordan]

What's the steering problem?? Does the mani or dp hit the steering column or the rack or something? Engine shots look great ~ and straight cut gear whine ftw! lol

[projectdrifter]

im not going to put his life out there but i school full time job and being military dosnt give much time for internet play. i pmed u back. i will get ahold of him and get back at u.

[KrazyZenki]

What's the steering problem?? Does the mani or dp hit the steering column or the rack or something? Engine shots look great ~ and straight cut gear whine ftw! lol

With the manifold extending past the block it leaves no place to mount the ps pump. I was looking into getting an electric hydraulic pump to remote mount but trying to find one thats run at the right psi to avoid damaging the rack and one that raises psi when needed or if its needed. Anyone heard of doing this or can anyone recommend a pump I could use? I was going to use an NSX pump because they are electic but they mount right to the rack and have an arm that moves the rack and is controlled by an ecu, so thats a no go.

congrats now we are believers

[codyace]

I really like your setup bud....super clean and well done...I like how you took into account the heat aspect and made some nice sheilding for it...any plans of getting the manifold and turbine housing swain coated??

Either way, good selection of parts, and nice numbers! I can't wait to see more dyno graphs when you're able to spin it another 1000 rpms more :D

LOL @ Steve about throwing the stock internals in the trash too...I can't wait to see what he and Mr. Griff are able to make with the 2.2 car and more boost :D



And thanks to all those who also have complimented my setup (nice to see you here mike) and it's potency....understand though that my car's purpose is MUCH different than this ones is (or has become much like the owner has stated)...however this car is still torque enough (and quick spooling enough) to be obviously be very very very fun on the street :D. I'll be throwing a set of cam gears in here in the next month or so, and will be re dynoing to see how much more torque I can gain :D

[PoorMans180SX]

That is the turbo position I have always thought would be sweet on an SR, allowing the runners to be the correct theoretical length. Are you gonna coat it with anything? I'd vote Swain ceramic inside and out.

Props man!

I as well love the turbo position. Ill have to look into the swain coating, whats the benefits of it over jet hot coating.

[codyace]

Swain coating is by far the best stuff available in terms of heat coating. It reduces underhood temps by far the most, and really works well...

www.swaintech.com...


(FWIW: THat stuff is used on the Space Shuttle!)

[PoorMans180SX]

Yeah, get White Lightning on the outside of the manifold, exhaust housing, and downpipe, and TBC on the inside of your exhaust ports.

It would be tight to see how different the dyno runs were.

good 2 see u aboard the board cody. i might have my t4 housin swane coated with my dp as well than have a turbo blanket put oer the exhaust.

on a side not cody's car is fasy dont let him fool you. not sure u can get much more out of the setup he is running. personally i was going to duplicate it but i have a massive turbo laying around and well im more a highway brawler than anyting.

is there a reason you didn't get a standalone?

How's driveability with that low end?

Coming from a V8 background to start, I say down low, the car drives much like any V8 Mustang or Camaro does...it's got enough torque that you can pretty much put around in 4th most of the time...thus saving gas and wear/tear. The only places I ever have had a problem with it being 'to quick' is when I get a littttttle to agressive on corner exits on the track, and I end up just roasting the tires off...but a set of R comounds would fix that undoubtedly...aside from that I love it...there isn't anythign else in the world that is more annoying to me than turbo lag, so it's my goal to eliminate it and create the most 'v8-like' car possible.

...I just hope these cam gears give me even more (to quote Steve Shadows) 'blast from the past v8 feel' :)

It will be fastarded....

dont worry...


That's what I like to hear :D Now are you using one of those stroker kits, or going with a 90mm Piston?? Either way that turbo is gonna spool so quick!

[projectdrifter]

cody i cant wait To have my big turbo setup. maybe get a few highway pulls on you. heck lets take it to island dragway.

[EchoOfSilence]

so how is it that you were going about eliminating turbo lag? i don't see an ALS system.... school me. This is really interesting...

[codyace]

so how is it that you were going about eliminating turbo lag? i don't see an ALS system.... school me. This is really interesting...

Well not in the literal sense, but I'd liek to achive my goal of having 20 psi at 3400/3500 on street...I already have it at 3700/3800 and want it sooner. I can't afford to go ALS as I can't afford a real ALS turbo.... I guess a real comparsion would be that I want to pack 400 whp/2871r into the spool range of a baby t25 on an SR heeh...

I also like how on track, I can pretty much be in any gear at any rpm, floor it, and have a full 20 psi with a second, ready to get goin down the next straight...that deals with transient and off boost, but you catch my drift...

To me, spooling 20 psi at 4800 rpm is painful...I just can't stand waiting for boost to come on...call me simple, but I'm a HUGE fan of being quicker rather than faster.....

KrazyZenki is using a standalone. I was talking to Cody

:hsdance:

[boostin13b]

oh, I see. I've noticed down here in Florida, 99% of SR guys rely on rom tunes, I'm not a big fan rom tunes if your going for high horsepower. I typically run AEM on most of my customers cars as well as my own, and if they don't offer a box, then I'll fall back on Power FC, microtech or haltech.

[steve shadows]

or you could use a flying lead with the AEM.

haltech offers patch harness for pretty much everything

['90RPS13]

So would a Power FC be out of the equation for this setup? I am wondering, I just picked up everything minus the turbo and standalone. And wanted to consult on the next move. *a

Power FC would be good for this setup. I'm a fan of power FC and have good luck with it when I use it. I would rather go AEM for full standalone though.

[GSXRJJordan]

Great dyno graph Zenki, and Cody, we love your setup man :)

PowerFCs are great if you have a PowerExcel tuner around. If not, you might as well throw it in the JDM trash, 'cause tuning with the commander sucks the big one. Haltech and AEM can be tuned by anyone with a dyno, which gives them the edge in my book.

The commander isn't too bad. The stock Map that come with them is actually pretty decent depending on what turbo setup you are going with. If you know your way around the Power FC, it's not bad at all, it's not as easy as tuning a map on AEM or Haltech but it's also not as pricey if your on more of a budget, I would rather save up the extra money to go all the way personally.

[codyace]

The whole Standalone vs Rom tune is going to go on for ages, and IMO (and experience) that unless you're going to someone who is extremly profecient in that specific tuning, that ROM tunes are the better overall option for 500 whp cars and below.

Now I understand that a true standalone, like Haltech and similar offer a greater ability for extracting the most power out of any particular setup, but I look at the total cost of the setup and the cost of getting it tuned into the final equation. To me, the 20 to 30 more whp you can may not be worth the 1500-2000 total dollars for a tuned EMS system....plus how many can actually afford to dump that much cash into a car that may not be even worth that much!!

Another thing we all need to take info effect is the fuel we use. Not sure if anyone else has taken notice, but e-10 has been beeing pumped into our gas now for a few months, and even JWT has begun not offering 93 octane program because of the irregularities in gas across the country. I'm running a 91 program, and love that I went that way...as there is that built in buffer 'just in case' I got another tank of bad gas (which I have twice in my life, and almost caused the end of my Turbo Altima)

Lastly, no EMS is plug and play and right 95 percent times out of the box like a rom tune. Call up JWT or Enthalpy, get your ECU socketed/chipped, and put it back in, and have fun. Now for those who say 'they are to convervative', you always have the ability to datalog a dyno run, and then send it back to your tuner of choice for a even more refined setup...so you're now 600 total into a custom sepcific tuned ROM for your car, that includes every function that car had stock.

Am I saying EMS systems are junk? Certianly not. Get a car with a custom turbo header and setup, and you can have the best setup possible....but you will only gain the advantages if going to a tuner who knows your choice of EMS inside and out...As I've said, no use in reinventing the wheel. Why run a t28 with stock cams and intake and parts with an EMS, when with that money spent you could have gotten cams, an exhaust, an intake manifold, and a rom tune and made some good power...

Will I someday potentially look into a Standalone? Yes, but only when I've maxed out my rom tune setup and can afford so...but at that point who knows where I will be with my car...I'm very very very content with my power now, and don't feal as if i need much more....

[scottie]

Well said Codyace! That is exactly my thoughts. The only reason i would go full standalone is if i wanted the 2 step, boost by gear or other features. As for extracting more horsepower, its not worth it to me. The AEM or equal would be the only thing i would look at. I used to own a Power FC and i can honestly say the stock ECU with a 4 map chip upgrade is better engineered. The Power FC didnt work so well when it was really cold outside. Seemed like the engine just didnt run as smooth as with the Nissan ECU. So this is why i went back to ROM and will stick with it until i go over mid 500rwhp. There is enough research and tuning experts that are so efficient with the ROM tune that it makes sense to go that route. I would like to see if people can start running twin MAFs like the Skyline to get over 600rwhp on a ROM tune.

Awesome. That was exactly what I was looking for Cody. Preciate it. *a

[EchoOfSilence]

where did you get your ROM and tuning from, cody?

[codyace]

Jim Wolf Tech...(no offense to Enthalpy, as he's a Genious) only place I'll ever go...


I'll be redynoing in the spring with my cam gears, and sending the datalogged run to Clark for a retune (even though i'ts pretty spot on now), as well as for the Meth Injection, and Launch Control...

['90RPS13]

So, I am going Thursday to the machine shop for my mani. So do I tell them I want a Top Mount Theoritical Length Manifold? Haha, first time I have ever needed a custom mani. Just trying to get a heads up.

[forum04pl]

any track times by any chace? im just wondering because im currently running a 3076r on built bottom end that im going to get retuned next week. ive been looking for what normal track times have been for this setup or ones close.

[hahahahaha]

^ ^ ^ ^ ^ just a built bottom end? no cams? valve prings? hg?
how much boost?

[hahahahaha]

k if its the 437 whp on ur sig with tires and lsd id say u can maybe see low 11's or maybe even high 10's im just guessing .. cause my friend has a stock motor with a hks 2530 and he runs a 12's low 12's so yeah o and thats with like a 1.7 60ft .. and hes at maybe 320whp so 437 and ofcourse suspension and good tires 11's shouldnt be a problem at all... if u grip of course

[forum04pl]

well the full specs on the motor are tomei cams, peak performace valvetrain, apexi headgasket, cp pistons, stock rods and crank. this is with a full race 3076r and a apexi power fc. it made that power on 21psi on pump at the end of the summer, but stock bottom end. i built the bottom end this winter and am going back for more pump numbers and some racegas numbers next week hopefully.

i figured it would pull low 11s with traction, but who knows with racegas and slicks :)

[hahahahaha]

pump numbers and some racegas numbers next week hopefully.

yup yup ... good luck ! and hope u get some good numbers ... and hopefully 10's at the track with traction .. :bigok:

[forum04pl]

haha yeah and alot of broken stuff all season!

Codyace, your dyno graph just convinced me not to go the LS swap route! I am new to the 240sx scene, and my previous project was a 98 maxima with a swapped 2004 VQ35DE, so I really feel the lack of torque and power in the low end before the turbo kicks in on these smaller engines. I've looked at a bunch of dyno graphs and the curve goes up just too late for my taste, so I was considering an LS swap, or another VQ35 swap (love that engine). But now that I've seen your dyno, I'm sold! Awesome!

KrazyZenki, those are some amazing numbers! Have you run the 1/4 mile yet?

Props to both of you! Hopefully I'll be able to learn as much as I can from this forum and achieve something close to what you two have done :)

Hehe thanks! It's a fun car for sure, but never discredit the awesomeness of an LSx swap...you'll ahve damn near equal power with simple mods, have a very cheap aftermarket, and have gobs of fun low end torque. I could never bring myelf to swapping one in, but heads/cam/tune LS1 even is going to bring in some awesome numbers...

Either way you go would be balls fun. The car as it sits has no problem beatin gup on higher power cars (weight)...but I would always wonder how quick a 400/400 LSx engine would be in the same chassis :D

what i'm wondering is why your curves fall @ 6500? is that the turbo choking?

also, do you think you may achieve better response + more power with a different exhaust manifold?

would you ever go equal length?

[codyace]

If directed to me:

The torque curve does fall off, but still at redline it's making near 285/290 ft lbs....I think mainly because it's a T28 at heart, but in the same respect I'm making 400 whp at the same time...so loosing the torque at that range of the rpm is the least of my concern...

And on track I tend to shift at 7k anyway...no reason to take her to the limit all day long....shifting to the next gear is right back in the sweet spot anyway, so it's more of a continuation of carrying speed, rather than making more...

I was in the works of setting up an exhaust manifold test with Full Race and their new bottom mount vs my swain/extruded OEM unit, but it ended falling through...mainly because FR wanted me to be running a tunable EMS vs my ROM to see if they could extract any more power out of it...not saying it is, but in my mind that basically tells me for all intensive purposes that mine performs equal to theres on ROM tune cars. Plus I like the idea of the factory log style manifold to help keep spool times fast as possible, and to create more low end trq.


Like before, I will be dynoing with cam gears here in the spring....maybe if I can find some extra duckies laying around, I'll get a new OEM unit and make a provision for external gate (like the FWD guys do) and go from there...

[hahahahaha]

okay i saw ur graphs and ur numbers and mods .. maybe compare it with my brothers .. as of what i know he should be getting the following items in and get tuned by nexy month or so

all items he all readys has but needs to get them in and tuned!!!

*gt2871r.64
*740cc injectors
*megan exh mani
*fmic
*hks ssqv
*brian crower 264 cams <-- didnt want the 272's cause he wanted a quick response
* brian crower valve springs with titanium retainers
* tomei 1.2 metal Hg
* greddy RAS
*arp head studs
*AEM EMS
*3.5 bar map
*full 3ich exh

and i think thats it well he has alot other lil bolt ons like sard fpr walbro fp and so on but those are the main things .. what do u guys think he's gonna get? i think its a lil similar to cody's just the fact that he doest have a rom tune or he doesnt have all the swian and porting or whatever that is on ur turbo .... also he will be getting tuned on pump gas 91 so yeah

[EchoOfSilence]

the swain coating and the extrude honing would make a big difference though

damm it so ur saying with out the hounding and so on there is no way to even see 400 whp?

also isnt the dico potato smaller than a 2871r? cause my friend made 375 whp on the a disco potao ... and i was impresed @ 17 psi with 340lbs of TQ and 100 octane .. o and also a built head hks camd and so on

[EchoOfSilence]

Is that like, the third or fourth time you've posted those same exact words? :rofl:

the shop needs to know what the hell they're doing, and oyu to be sure of it
might as well go full-race if you don't want to extrude-hone your stocker


What I think would be nice is a short-equal length manifold but obviously that's hard/inpossible
I don't like the idea of log-style manifolds...

[codyace]

What I think would be nice is a short-equal length manifold but obviously that's hard/inpossible I don't like the idea of log-style manifolds...

I really wonder what the gains would look like...certainly not worth the cost Im' sure...

The newer twin scroll setups are nice (that F/R offers on their top mount manifolds) and I believe they work well, but again, cost per users able to purchase them...


damm it so ur saying with out the hounding and so on there is no way to even see 400 whp?

I definatly think that copying my setup is about the only way to get near that mark with the t2 manifold...but regardless, anything over 350 whp with this turbo is unreal to drive...and will be damn fast as it is...aren't guys already in the 11's with slicsk with 350 hp setups??? That's fast.

also isnt the dico potato smaller than a 2871r? cause my friend made 375 whp on the a disco potao ... and i was impresed @ 17 psi with 340lbs of TQ and 100 octane .. o and also a built head hks camd and so on

Built head and the 100 octane maybe part of that reason....but that's really stretching that poor spuds effeciency range...if possible post a graph...I wonder how bad it died off....again total area underthe curve >peak power ANY day of the week.

[hahahahaha]

yeah well a buddy of are's has about 320whp and hits 12.1 so yeah i figure anything above that will hit 11's on slicks and ill try and post a graph ill ask him for it .. also the dyno guys tried to squeez 400 out of it by raising the boost to 20psi but it made no more power so yeah

[Teambadrun]

Must be american dynos but the most ive seen from one of them is about 280rwkw @ 20psi

[delphis]

not to rebump an old thread or anything but I found the same exact dyno sheet on brian crower website is this your dyno sheet on the site? if so congrats!

[KrazyZenki]

Yes that is my dyno sheet on brian crowers web site. Ive talked to him via phone a few times and I atribute my higher than normal hp numbers to his cams and my custom exhaust manifold.

[Z U L8R]

good stuff man, i love my turbo too. ball bearing turbos own. i may be going 35r soon so i may post mine for sale in the near future. it's been on the car bout 300 miles. gt30/71 flow their asses off, it kicks in bout3500 on my rb25 full boost is 4.0-4.1k, at 3700rpm it's making 350 ft lb's at 22psi, at 20 psi it's almost 260ft lbs. lol, huuuge difference in how it feels lol, good choice on turbo's, i can post my graph if you care +111 g/l

i'm running power fc, i wish i had datalogit so i can log my knocks, and we could probably add a little more timing but 20psi on pump gas with a safe tune (basically 12.0 a/f across the map) is pretty high, i usually'll turn it down to 17-18 unless i'm playing with someone.

a friend of mine just switched to aem ems from his old stand alone (don't know exactly) on his TT supra and he gained 175 ft lb's.....

i'd like to go aem in the near future, since everything can be logged, i can go map sensor, it can do 2 step, etc etc

AEM EMS ownz!

Series 1 RB25DET, internals = all stock, no headwork, stock cams, Commetic 1.2 mm headgasket + ARP head studs, GReddy Intake manifold, Z32 maf, blow through set up right in front of the q45 throttle body, 550cc deutche werks side fed injectors, ngk 3330's @ .028 gap , buick grand national coil pack /w 8.5mm msd ignition cables, XS Power exhaust manifold (modified flange so compressor would clear the valve cover), tial 38mm external waste gate recirculated, GReddy profec b (old school), Blitz Bov a couple inches in front of maf, 3" exhaust, basically bolt on rb25 /w HG + studs

[Z U L8R]

I'd like to get that dip out of 4k-5.5k with a little more timing but, without datalogit i can't log my knocks so it's good enough for now. 12.0 a/f across the map, pretty sure with cams/ported head my torque wouldn't fall off like that either, cause those turbo's flow like a mofo

GT30/71R = very good turbo

[KrazyZenki]

Nice powerband, nice setup!

Quick question.

So if I`m reading this right, a single scroll 3071 .63 A/R can see full boost with a built motor before 4K rpms? Hmm.... possibly going to go this route!:coold:

And race gas power is 400-450whp?? nice so I would say a consistent safe 375whp is attainable providing a good motor?

wow im surprised the power this turbo has been putting down. for some reason in my head i dont put it in the same category as the 30r, but closer to a 2871. i guess that gt30 wheel does wonders. does the 71mm wheel match better with the gt30 wheel than a standard 30r? [email protected] on a dyno dynamic. thats more that steve put down on a 30r. And steve has countless hours on his tune. either way impressive numbers.
