Anyone over 400rwhp?

[Boostage]

Anyone here making over 400rwhp in an S car? s13 or s14 is it scary? hard to control? just want to have an idea of how it feels in these cars. I know in heavier cars mustangs/Camaro's its not soo bad.

[Grenade180sx]

its not scary unless you drive like an ass hole.


and it depends on what turbo is giving you the 400 horsepower.

a smaller responsive turbo will be very fun, but if your running a t66 boost will come in hardcore and things can get scary quick if your not ready for it.

[Thursday]

NA 400rwhp can be scary in a LS1 or other v8 swapped s chassis.

pm some of those guys and ask them how resposive it is.

[kensreliableb18b]

if you have to ask then it's not for you.

[GSXRJJordan]

if you have to ask then it's not for you.

I tend to have this attitude also.

Steve Shadows' car is definitely over 400whp, and seems very responsive. Just like anything else that has more power than grip, as soon as you floor it, you expect the back end to walk a bit if you're not pointed in a straight line.

Nothing is scary unless it's unexpected.

[((sr)) kelly]

if i ever get my car boosting right itll have over 400whp :(

[Syncade]

Any hp can be scary if you are on the right kind of road

I miss my Pennsylvania mountains so much :cry: Living in states where it is flat is just torture when you grow up in hills

[mugendork]

400hp will only be scary your first time stepping on the throttle. Your driving style will definitely have to adjust, but you get used to it. The screwed up part is shortly after you hit that 2-3-4-5 hundred horsepower peak, it wont be enough. You get used to it..

Very true..... i went from 230whp to 330 whp and that was a blast for a few days.. im sure that the 400 whp rush will be short lived as well..

id have to say its not really the HP that scares you.. its the torque.. imo

Query, would you suggest then when building an engine, if your goal is 350 HP build it to withstand 600 HP that way when you reach your goal and get used to it, you dont have to rip the engine out and re-building to get more hp?

Also super newb question, if a KA, SR and RB 20/25/26 were all running at 500 HP would the cars feel significantly different other than torque?

[Full-Lock]

its not hard to get used to

yes

.

hard to control

depends

tires not hot? yes

tires too hot? yes

too much air in tires yes?

do I need bigger stickier tires? yes.

Is it fun getting sideways in 3rd sometimes? yes.

semi-laggy? barely.

3076R- 18 psi - 91 octane - Red Top - Haltech - Greddy IM - 264 HKS


ive noticed laggier but with 50 more whp is easier to control.

Also not quite as fast on the street. Fast at track though (old setup with T61)

its not hard to get used to


graph please

Exactly. I'm over 400whp and I got used to it. It scares the hell out of people riding with me but it feels like a sentra to me now. :hsdance:

[Zerolift Autolab]

My S14 Made 469rwhp with Built SR 3071R, AEM + much more obviously

The car is alot of fun, with the proper tire fitment, alignment setup and most important - not driving it like a complete Jacka$$.

[steve shadows]

Yeah I get jaded pretty fast.

But then again with a 2400 lb weight (2600 with me)

it's a little more knuts then a soaking wet s14 with 450whp

I already have the itch, I want to build the other block I got then go for 500whp at 28 psi.

I mean if im at 405-410whp on the dyno dynamics at 18 lol - It should be plausible - the math on paper says so at least.

Ive just been beating on this stock bottom end for 2+ years now at that power level, I want a refreshed set of pistons at least.

anyways im just blabbing :blah:

wow...nice numbers..

[steve shadows]

cool none-the less.

torque leaves something to be desired? less than 250 under 5500?

what is that a T66-T3?

that has to be a sr20...

[steve shadows]

that has to be a sr20...

I make over 345 peak and over 300 from 4400-7

I have an sr (thats on a real dyno too haha)

16 psi -18 psi 91 octane (http://a126.ac-images.myspacecdn.com/images01/43/l_ac7d64c466f21a174cca27fbf196bd7d.jpg)

the spike is actually the boost controller over correcting (down to 15-16 then back up to 19 by the end of that slope), fixed it since then, should make even more power and torque now.

thanks guys

[Koopa Troopa]

Engine is 450 some capable however I am far from there right now :( For a car with a T04S and 270 cams my car is extremely responsive.. Hell the T88 180 I raced seemed pretty responsive too...

Just tuner. probably

Probably has more potential.

[Full-Lock]

yea my car did dyno 650whp with its old tune/standalone, super unreliable though..
which is why it was changed

yea
i dunno

the tuner is ivan from AMS..he has the quickest ka-t in the world i believe..
i was going to bring it back up there this summer and have him mess with it again..

Heres a thread with rb26's with a bunch of different turbo setups. I think your setup is good for 550+whp and 450+ tq. I have a rb26 with 2510's waiting to be put in a track car...that should yield 500whp and 400ish lb tq. Def get your setup retuned.

[donabeast]

i went from a shit ass civic to the sil80 i got like a month ago and im def used to it already the guy i bought it from said it was puting down 400+rwhp but i havent seen a dyno sheet yet 130mph in third kinda has me thinkin hes telling the truth but im def used to the power and will be finishing up the top end here in the next month or two

I was thinking the same thing, the power band for the 26s isn't usually that steep from what I've seen. Are you running stock cams? That might be the issue...

[McRussellPants]

Straight line 60mm+ turbos are boring, they're really lazy so you have alot of warning before you have to start pedaling it.

3071/3076 can get intresting drifting/racing. You just have to pay attention to where your RPM is more, beacaue if it catches you out of boost and then hits in, its a bitch to catch.

Other than that its all cake.

then again, if you drive like a chump you'll think everything is scary.

man I have a stock Ka and I think that is fast, so if I jumped into a 400hp 240 im sure I would get a hard on (;

Have you driven in any Minivans or hybrids in the past 5 years, because all of them are faster than a stock KA....16.1 1/4 mile hahahaha

[KA-T_240]

I run right around 400whp


You get used to the power, and how to control it. When I auto-x and road race I drop my boost down to 10psi. Its plenty fast, 400whp S-chassis is more then enough to slaughter vipers:). If its wet, its a completly different story.... I love every second of it!!!! I am glad my car is parked for 6+months a year, then I do not want more power all the time.

[Mi Beardo es Loco]

You have to build the engine with the driver. Kinda strange but every car is different and you have to get use to the lower hp first and build yourself up to go higher and higher. We have 2 400+ hp motors in our house, a Dodge Cummins Diesel and a 350 Chevy small block. My sr is pretty tame right now with the jun exhaust mani, stock turbo, and power fc. I was planning on maxing out the t25 stock turbo and seeing how far it will go before swapping but eventually just wanna stop at around 330 to the ground. It's a safe mark to really stop at if you don't want to build the sr's bottom end. When the motor eventually gets build I MIGHT go higher.

[landins13]

Query, would you suggest then when building an engine, if your goal is 350 HP build it to withstand 600 HP that way when you reach your goal and get used to it, you dont have to rip the engine out and re-building to get more hp?

honestly it would be smart either way to build the motor for more than your goals, with most of the boost controlers and management systems out there you can set the car up for different tunes, if you want the car to make 350 build it for 600, get it tuned for 350, and you will always have the option to tune it for higher or lower numbers, you can set it up with a low boost tune for 350 rwhp and a high boost tune of 500rwhp and just select which tune you want to be running and make sure you have the appropriate fuel to compensate, you can safely make 350 hp on mid grade, but for 500 youll want to be running higher octane race fuels, it is possible to make 500 on 93 pump gas but you will need someone very talented to tune the car safely on it.

you have an excellent point + 1 for that, I will keep that in mind whenever I get around to my build

well, it depends on how far you really want to go. That's what I'm doing but it does get expensive to prep your car for 500+ and only run 350 on it. If 350 was as high as you were going to go then build it for 380 and detune for 350 to save some cash.

[GSXRJJordan]

Build for ~400whp (as long as you've got good compression already) = head gasket, cams, walbro 255. The bottom end's good for it. The mid-300s are popular target numbers because the car's very fast at that point, but you're using turbos that also allow great response, and doing it all on the stock internals (without cams if you've got a GT2871 or bigger). Build to that point (for not very much money), then decide if you're ready to build the bottom end and go for more.

[origin_s135]

stock ka was pretty bad, when my car was stock back in the days, i used to drag race in the naval base[it's SAFE!] with a friend. he had a single cam vtec 92' civic hatch[probally w. headers and exhaust, intake,]. i used to take off then second gear he fuckin smokes me. i got mad so i got the swap and he didn't want to race me anymore. haha. but to get back on the topic, i sat in a supercharged cobra before, forgot the numbers it was putting out, but that thing scared the shit out of me. it was the first fast car i ever sat in, my hair was standing on end. haha. like someone said in this thread, it's the torque that will get to you.

[steve shadows]

Some tuners just arent Nissan peeps.

That torque is just wtf?

I tune sr's that make twice as much everywhere...

See how much the Tuner matters guys!!!!

[Jodan]

i run roughly 450hp on daily driven boost with my KA-T, SC61/ar.70, EMS, BIG fuel (2x 255's, 1000cc injectors, 0.8 lines) ive got room for about another 200, making mine one of the fastest around. it is scary at first but im more than used to it, ill see what happens when i go for the 600hp mark.

[Erjay1]

Im new to these cars and these SR motors. What kind of numbers can I expect from a stock SR motor with a stock turbo or T28 I believe? Cams, full 3" exhaust and a good tune?? +300whp??

Also, what would it take to achieve 400whp - 450whp daily driver?

[Jodan]

t28 depending on s14/s15 will get you around 300 safely, no more than that. the cams will give you kick ass powerband though, depending...

Yeah I have room to go to 600 B hp too.

If your built do it already. I have all oem parts in my lower half right now.

I'm waiting until I have the other engine on a stand ready to go before I do the 28 psi max out

SC61 is a good turbo but with the T3 hot side it runs out of breath around the same levels a GT30R does.

GT35R is better, better turbin wheel, more flow- get the .82- or get the gt40 back side.

If your using the T4 hot side with your T61 then you should be fine though. (P trim wheel is the shit btw try it out)

[Jodan]

im looking into a new turbo after i build the head, im all stock right now up top, but the bottom end is 100% built. my current turbo is good for the 600 but not reliably.

[Erjay1]

Sounds like these SR motors can put out over 400whp on stock internals, am I right?

[Om1kron]

LOL -stock KA fast- Ive heard em all now... (;

heh, stock ka is fast enough for me now. I just drive to and from work, I dont need to get to 80mph on the freeway in 3 seconds lol. And burning half of my tires rubber to get there.

But picking a platform to build had a lot left to be desired. I cannot decide if I want to go ka-t / sr / rb26dett / or vq35

sigh... I want boost :(

[Jodan]

yeah^ depends weather is solid or not. ive seen 460ish with a cometic and some head work. not to mention fuel/boost/ignition/tuning.

[steve shadows]

Sounds like these SR motors can put out over 400whp on stock internals, am I right?

Ive done north of 410-465 whp for about 2 years on stock internals (bottom end)

the only thing internally modified on the long block is valve springs, cams and retainers. Not really anything overall structurally stronger.

I beat the crap out of my car too, track days, daily driving lately, weekend cruises, fwy runs from time to time, dynos for fun etc.

100% stock oem parts down there.

Hybrid Dynamics did 600whp on stock bottom end on a dynojet (450 trq)

They raced that car for 6 months IIRC, and before that they were eating throttle bodies through the motor for a 1 year at 500 + whp, running high 10s low 11s.

It's all in the tuning.


If you remeber Scott Avoy he also did 520+ whp on stock bottom end very similar setup to mine

http://www.youtube.com/watch?v=qlYZYOqsYD8

In Car 400 whp level

don't let the description fool you, it's all oem bottom end, I know Matt Vasello (over the i-net) he's in the video.

This is my current 240 2 years ago with a T61/T3 and just street tuning , around the 380 whp range

TUNING TUNING TUNING

bad tuning, shitty piggy back = engine fail

Standalone + good tuning = Infinite possibilities - like 400-500-600whp on stock sr bottom end for long periods of time.

Why would you want to go with a VQ35? Its so expensive to mod if its NA. Only worth it if you're looking to boost it but it will cost alot. Thats why Im ditching my Z.

Probably around 450 whp range on a dynojet. A lot of people over inflate their figures or compare to insane japanese tuning shops that are running higher compression and better gas.

You should be at 450 whp on 93 octane witha decent safe tune.

Your torque curve should be violent and close to 380+ levels maybe even 4.

I am not the best at predicting outputs (espeically without the car in front of me and without knowing the quality of the build and especially tuner) and I havent had a lot of RB's in the shop (26's anyways).

Splitfire coils? Big whoop, Stock nissan coils are usually good to 500whp+

Not 100% sure on RB coils though.

[Om1kron]

to get it bar'd and leave it stock... but what fun is that, I want a turbo motor to play with and tune.

[YoungGun]

Lol in the first video. Tuner: "As you can see right here it's like bahhhhh"

[steve shadows]

That's a technical term for " Spiking curve (adjust timing/boost controller)" haha

[landins13]

im sitting about 540rwhp, its not bad once you get used to it, but with ym clutch and all it cant really be a dd, technically yes i could daily drive it, but gas is too expensive, and rush hour traffic on a twin plate unsprung clutch sucks. plus that what my 92 coupe is for.

[Rick-95ZE]

RB25+GT35R+wide sticky tires+good suspension+ HLSD+Responsible driver = I'll let you know:D (i'm still at stock boost)

[Rick-95ZE]

Anyone here making over 400rwhp in an S car? s13 or s14 is it scary? hard to control? just want to have an idea of how it feels in these cars. I know in heavier cars mustangs/Camaro's its not soo bad.
