DYNO results

[ROIDMONKEY]

Finally got my car tune today or semi tune since my power fc ended up bad so i've sent it to repair so i got me an AFC for now untill i get the PFC
mods
sr blacktop
HKS 272 step 1
Greddy Rocker Arm Stoppers
T28 (s15)
Greddy elbow
greddy TI c exhaust
FMIC XS power
HDI boost controller
nismo 740cc
nismo FPR
Z32 MAF
APEX AFC
HKS Super Sequential Blowoff Valves SSQV

made 296.74 torque and 289.44 HP. that low numbers was the first pass at 6-7 pounds the other one we tried 20 pounds but boost falled down to 16 pounds right at peak , we tried putting a T and got a bit better but still falling to 16 it wasnt holding 20 , i think if it can hold 20 pounds it would go up till 320 or so
once i get the PFC back from repair we will try again . dont like the AFC , it is momentary

Looks like a nice setup!

How much boost can you safely run on a stock bottom end SR?

[ROIDMONKEY]

Cant answear that question since is my first SR . im boosting 16-18 right now

well, on race gas as long as the AFR is clean and the head gasket holds up, its really more a matter of how much power the internals can handle, on pump i would think 20 would be pushing it, esp since its blowing hot air at that point.

[harangatang]

289 whp and 296 tq?? To me, that sounds pretty good for a stock sr minus cams and a t28. And you shouldnt be boosting that t28 to 20psi. It wont like it at all.I believe the efficiency rating is around 15psi if I'm not mistaken.

[steve shadows]

nice man im a fag

[Gjohnson7]

Alright, that's basicly what I was getting at. 20psi on a almost stock SR seemed like a lot to be pushing.

very sick how that thing pulls u when boost kick in .

hook up a catch can to that valve cover T before you drip oil on the exhaust manifold and blow the welds on the passenger floorboard

ehh i read it wrong, i think.

I dont know its high.

I thought it was 296ftlbs @ 7psi. I was going to lose it. 16, sounds closer, but still way high...

[ROIDMONKEY]

U got it yes , fynetune really nice dyno setup. it was falling down to 16 but boost controller was set to 20

[johngriff]

DynoJet is not a nice dyno setup.

Maha (http://www.maha.de) is a nice dyno setup.

DynoJet is NOT a load bearing dyno, that is why your boost controller was dying.

[Z U L8R]

not too shabby for afc, you'll make more power/torque through out the powerband once you get your pfc back. i wouldn't recommend you push it passed 16psi either though, and yeah ~300rwhp pulls pretty damn good. good job man. my only advice is (and i'm a total hipocrit) u gotta know when enough is enough. like turning it up 4 more pounds of boost, which is mostly just hot air, to only gain ~20hp isn't worth risking the motor in my opinion. just upgrade the turbo. i don't see ur motor lasting that long @ 20psi on this t28, i think you'd do fine keeping it at 16psi till you got a bigger turbo. just my .02 . i'd rather see you kicking peoples asses with 300rwhp than spending money on internals for your sr and driving around the beater. if i were in your shoes i'd keep it at 16psi, when the pfc comes back in, get another tune @ 16psi. and drive on the new and improved 16psi while saving up for the bigger turbo + exhaust manifold. all in all i think you did a good job, nice numbers
Dave =]

[johngriff]

Doesn't matter, tune ignition timing around fuel and boost, run as much as the octane rating is going to handle, 4 more psi isnt going to break the cylinder head off the engine.

[hijack3d]

Is it just me or does 760cc inj. seem a tad ... excessive?

[statik]

Is it just me or does 760cc inj. seem a tad ... excessive?

maybe he plans on upgrading the turbo later, the price difference between 550/650/750 is negligible

[((sr)) kelly]

if you want 20psi you need a 2871r atleast

[hijack3d]

That makes sense. Esp. since he says he's going with a PFC soon... I probably would've just gone w/ kicking up the fuel pressure with that adjustable fpr until then. But that's just me. Oh well.. pretty impressive for tuning with an AFC and humidity up the ying/yang.

[DrIvEsldEwAyS]

the s15 turbo will not hold 20psi, you will need something bigger.

[ROIDMONKEY]

maybe he plans on upgrading the turbo later, the price difference between 550/650/750 is negligible
correct , ill be getting a 2871 soon

[Hooorahh!]

wow nice numbers but s15 turbo 20 psi:loco: try more like 17 psi MAX .. avg 15 psi but max id say 17 ...
good numbers thoe

[steve shadows]

yeah he would be around 240 on hp and 215 trq on dyno dynamics at 16-20 psi.

I just wanted to compare these in my argument in favor of larger journal bearing turbos over smaller t28 at less boost

just compare straight accross and keep in mind the dyno dynamics reands 15% LOWER than DJ.

this a customers car I tuned at 12 psi on 91 oct.

just fyi.

You still have more power to be made with a little more timimng map and steady state tuning of the cells.

ps you cannot do this on a dynojet

only DD. fyi

I know a pro Japanese drifter the #1 guy on a s15 turbo runs 1.2kg wich is 17.4 psi.. Dont listen to anyone until you see it for yourself.. 18 psi is max for s15. I ran 15psi for a year on my silvia t25 100 octane no probs and drifted and touge the shit out of it!

And a stock bottom end!

sure you can hit 25psi with a t25 if you take the vacuum line off the actuator.....turn the boost up ftw

I just noticed u have a 280z , my buddy have a 280 also with a RB26 pretty cool car . love them. hes only making 340 right now . stock turbos at 10 pounds i think . hes putting 2 T28 that he just got , lets see how it goes

BTW i just beat my friend GTO pretty good :) . he got the LS2 version with "400" hp

[Z U L8R]

Hopefully turbo dave has time today to help me modify my manifold to get his frankenstein turbo on it then tune me up, i'm shooting for 600 but anything over 5 and i'll be pretty happy. my luck i'll get 492 and it won't budge anymore hahaha. i'll let ya know how it goes. i'm on hybridz also , if your friend's on there, what's his screen name?

[White Comet]

to get back on topic, am i the only one that thinks the op's numbers are low? my friend who is a member on here has similar mods on his redtop sr except he has a pfc, no ras, stock cams and stock s13 turbo. at 15 psi he dynoed at 277 hp

[posdrift240]

4 PSI Can be the difference between life and Death, My buddy cracked his cylinder wall just going from 12 to 14lbs of boost. So it can happen,

Good numbers man!!! Keep up the good work. I like seeing good numbers, Dont let these guys intimidate ya on here, There prob just pissed because they cant get those numbers out of there motor, Everyone's setup is different and not everyone can handle it.

So congrats!!!!

thats awesome bro. wondering when my PFC comes whats gonna be my numbers , cant wait
well i dont know about the dynojet or dynodynamic or any other dyno but i spanked a GTO last night pretty good that comes with 400HP LS2 right? the one with dual exhaust

[DUBCITY]

are u still on stock head gasket?

those numbers are nice for the t28, but you can see it does fall on its face pretty hard higher up.

also, youre running HKS Step 1 272? on both sides?

do they even make step1 272?

when i had 441rwhp/[email protected] it'd hook with 245/60/14 bfg t/a's which is a pretty soft street tire, i could roll onto second gear and it'd hook the whole way. once they had 40% life left on em they would spin a little though. all in all however i think it's in the tranny. those were 14x7 rikens that had the bfg's and i was running the rb20 tranny at the time. now i'm running a z32 tranny which i'm REAAAALLY liking at the moment. first, second, and third are really close, fourth spreads out a little, and fifth is good to cruise in. i'll spin tires just rolling into 3rd and 4th once it gets to 5-6k rpm, it's still pulling since it's open diff but you can hear em screaching lol. i'm gonna get some mickey thompson et street drag radials...hell they're cheaper than the brand new potenza's i got on the rear right now lol. right now i'm running tsw 16x7.5's with bridgestone potenza pole positions 245/50/16 w-rated. i thought my rear end was a 4.11 open diff, but i think it's a 3.9 open out of an 83 280zx. it's a little short, i'm haulin till 120mph, but then i go in fifth, which with this 3.9? i was trapping 125mph in the 1/4 mile so that last shift into 5th kills it, the stock 3.54 open diff was too long and i was only trapping 122mph with that, it'd hit 145 in 4th gear.....the perfect rear end would be a 3.7 lsd out of an 88 turbo 300zx. can't wait to find one.

sorry to get off topic but you asked about traction.
my advice to him would be to go with some drag radials and if that doesn't help then go with a lower gear ratio.

[Hooorahh!]

im running right now at 16 :) . thanks bro
ill try to get the 2871 before i get the PFC back from repair .
average boost for 300-320 on a 2871 is?
hmmmm id say about 14-16 psi .. all depends on tunning and what a/r u get .. smaller equaly quicker spool but a tad bit smaller hp ... small a/r will max out at around 360whp .. unless ofcourse u port it / modify it of course .. but avg 2871r .64 will max out at around 360whp with quick ass spool .. or get the big a/r have a better top end and be at 390-420whp ...

[DUBCITY]

yes stock head gasket and yes 272 step 1

[johngriff]

4 PSI Can be the difference between life and Death, My buddy cracked his cylinder wall just going from 12 to 14lbs of boost. So it can happen,

That is a statement made on 0 quantifiable evidence. The reason a cylinder wall will crack is because of detonation. Detonation is caused by boost exceeding the octane rating, or improperly tuned ignition timing, or bad af/r. It is not going to happen because of increased pressure.

Even in the cheapest motors (kia, daewoo) you will bend and break rods/crank/wristpins on properly tuned cars with too much boost before you crack cylinder walls.

Your friends car sounds like it was open deck, I am thinking it WASN'T a nissan.

Let me try this one more time. "Taniguchi", "One of the best street and pro drifters in the world", who has the best sponsors in Japan, who rocks Japans circuits on grip, touge, drift, and on the street still to this day was or still runs a s13 SR20DET with a s15 turbo and boost it at 17.4psi in his hatch. The max is 18psi. No body here in the states knows much. Forums help out but not all the answers. How would a t25 turbo be maxed out at 15psi but the s15 t28 bb be the same first off? Its not! I get all my info for Pro or street drifters in Japan i will run what they run.

i thought you were getting all your info from superstreet. and since he's the best drifter in the friggin world you'd figure the best sponsors in allllll of japan would do something absolutely crazy and unthinkable like port the housings and put some better wheels in there (at least i'd ask for it).... "how would a t25 be maxed out at 15psi"......does it hold 15psi all the way to 7,000 rpm? i didn't see anyone say a t28 is maxed out at 15psi, i would say t28 should hold 17, sure crank it up to 17.4 psi for the quick .4psi of extra torque really quick (since you're drifting) and if it drops back to 17 at redline who cares, you clutch kicked it and the tires are already spinning. anywho, being best friends with michael jordan doesn't make you an nba coach. the point me and some other people that said no need to go 20psi, was that the minimal gain isn't worth the extra risk. enjoy your car, if you want more power than your turbo's capable of, then upgrade your turbo, why push it till it blows your motor or the turbo takes a shit. that's all =]

[johngriff]

You dont blow the turbo or motor.

You would just be boosting out of the efficiency of the turbo.

Like you know, a compressor map.

This isnt his only car. He has so many. Its not his pro car! Thats all HKS.

"how would a t25 be maxed out at 15psi"......does it hold 15psi all the way to 7,000 rpm?

Mine did even on a side mount. But i never took it apart so who knows!

i didn't see anyone say a t28 is maxed out at 15psi, i would say t28 should hold 17, sure crank it up to 17.4 psi for the quick .4psi of extra torque really quick (since you're drifting) and if it drops back to 17 at redline who cares, you clutch kicked it and the tires are already spinning.

They dont go by psi they go kg 1.2 = 17.4 sorry its the math.

john, so what's the point of boosting passed your turbo's efficiency? what's the benefits? what's the risks?

this is madness....madness??? THIS! IS! POINTLESSSSSSSSS!

do you think running 15psi on the stock sidemount is ok?

[johngriff]

there is no benefit at all. Its not making any more cfm, but its not going to blow the engine up just because its past efficiency, its just going to weeze and suck.

I was waiting for that man, cracked cyl wall, WTF? Not normal on closed deck at all and not on a good tune. I saw it recently on a new Solstice, open deck, that was pushing 15psi off a 20g without a proper tune.

risks- hot ass air coming out of turbo, I/C getting heat soaked and not doing its job, turbo dies earlier.

Benefits, none.

No 15psi on sidemount not ok unless in 20 degrees ambient temp (just an example number)

Oh and why 3 posts in a row, because I havent figured out how to wuote multiple people in the same post the way I want it to look, that I cam across the dif posts at dif times:mrmeph:

I think so, I did not see it last time I was at the shop, but I have not seen him driving around in it on base either. That poor kid was f'n hopeless, too much port work, no cams, oversized valves, no standalone, forged pistons and a 20g, man what a mix up of parts. Nice guy though. Dude where you there the last time they tried to bolt the head to the block while the cams were torqued down. We told em not to, it looked to be an interference motor, I think they bent a valve.

[Z U L8R]

i've seen stock sr's melt their pistons/crack rings from running 13psi on the smic. 15psi on a smic...no thank you.

[fro20]

Thats from a combo of the smic not taking the heat out and the tune not being proper for the car. Cuz if he had smic I am sure he had no mangement, prob just a B/C

damn that's horrible remeber i told u last time i was there, they where having all this trouble tryingt o figure out what was wrong, and I quickly said "A) Injector not firing B) Ignition coil not firing" then about an hour later they said they thought and injector was stuck open. kinda sucks but whatever. back to the SR topic. yeah I would never push more than 9lbs on the stock SMIC. once i got the FMIC I was pushing 1 bar all day =) (14.7lbs)
