What's the MOST RWHP EVER from a S2000?

he makes like 160 more whp and i would beat his ass on the street or track

you know, he could throw some nitrous on it (75 shot) and it would really make his car a beast. it would spool WAY faster and bring the power up really fast

well it's over 700whp from 105mph to 135mph, that's probably 6000 rpm to redline in 5th. sounds similar to some of the other big turbo dynos I've seen. it's always gay when dyno's are over speed and not rpm.

I love my S2000 and it's awesome but it's still only 2.2L. any small displacement motor making a lot of power is going to have a small range where it's making a lot of power like that dyno shows. if you want a lot of power and a broad powerband you need displacement

My big turbo has a little lag but ummm I dont have any problems with "unusable" power.

ha ha, I think you've got enough power to spare

I would be suprised to see a 2 liter engine make a broad power band no matter what turbo it has when its in the 600whp + range. There is a point no matter how much you force it, the motor is still a 2 liter and has its mechanical operating range = narrow/peaky. When you build for max peak, low/mid fall into place where they may. I think this is most evident in the 700-800whp graphs we have seen. You want to make more low/mid with your high, then your going to give up some high etc...

my 650whp will bust that ass too

broad enough

What turbo, psi, and race gas?

you've got basically the same powerband as that other dyno if it was over RPM instead of MPH.

some of camuman's dynos were in 5th gear since it was spinning 4th. at about 8400 rpm it was spinning the rollers at 132mph, at 104 mph he's at 6700. just guessing for the differences in rpm from the 2.0L motor to the 2.2L and use those speeds and rpm's on the 800+whp dyno and he's probably got 700+whp from ~7000rpm to 9000rpm.

so for the RPM range you're over 600whp he's over 750whp, that's not too bad

no its really bad...his dyno is horrible


he prob has 1000 or less rpms of usable power. with that steep curve you can tell its coming in really late. i run 125 in 3rd, so he is prob in 4th and that power is not usuable

DYNO QUEEN

^^^ your numbers are impressive no doubt, but from what I can see from the two dyno graphs from the shifting point of 6k on, your basically the same hp curve, yours just doesn't peak because your lacking 160whp, so I'm unclear as to how his is less "usable" or broad then yours? Also if i'm off in my assessment of the two graph comparisons, if he is lagging behind 1000rpm in boost so what? That's what a close ratio 6 speed is for. He's going to well make up for that split second a 1000rpms goes by from his extra 160whp

unless the other guy is going from 105mph to 135mph in 1000 rpms (highly unlikely) he's got 700+whp for the entire rev range of each gear when shifting at redline. obviously a broader range would be awesome, I'd love to have 700whp at 2000 rpm, never gonna happen though. the more turbo power you have the less low end / mid range you're gonna end up with, it's that simple. that being said it's still a wide enough range to cover the entire time he's in each gear.

i dont think you guys understand how this works...

1--i have longer gears than a stock s2k, so you have to take that into account

2---when you making 600+whp, how long does it really take you to go 20mph? maybe 1000rpms or less. if you have ever been in a s2k with much power, it is unreal the speed you climb

3--compare his to mine like kutsu did....his curve is made for the dyno...if he were to drive it on the street or try to launch it at the track, he would have major difficulties....that why they didnt show RPMS on the bottom and opted for MPH. because the graph sucks

In addition to the early and rapid spooling with N2O you would see a disproportionate increase at onset due to the significant intake cooling and a 75 shot might give you as much as 150 hp and 100+ ft lbs torque to bump the midrange.

N2O is beneficial in any boosted application and especially for high power numbers.

1- So you have less available wheel trq now but over a broader range, well if that floats your boat thats cool.

2- I can only speculate, my 350/ 210tq is no comparison, but logic would tell me it depends on traction and what gear your in. Gearing is the other important part of the equation as you know.

3- possibly, but we dont know what his trq curve looks like

I'd bet money that 800whp dyno is basically bstone's powerband just more exaggerated up top with a little later spool. unless someone knows them and can get a different dyno we'll never know so oh well.

don't get me wrong, your's and kutsu's cars are making great power. shortly I'll be running a GT35R and I'm not expecting to make tons of power down low. I just don't think the other guy's dyno is that much different than yours besides making more power, it's definately more than a 1000 rpm powerband.

Im not disagreeing with you.

im disagreeing for sure....

there is a reason why the shop posted in MPH....you havent looked at too many dyno graphs i see.

the whole point of tuning and adding poswer is to get it fast and hold it....not just spike up and hold for 1/2 a second

and as far as tq goes. i made just as much tq as Kutsu, and made it 1000 RPMS earlier. so there is no problem with my tq, i made the right turbo choice

It depends on what your application is, as long as your gear spread is condusive to a narrow high peaking power band then it doesnt matter how broad it is becuase your still always in the power band, this is ideal for drag racing, and tuning this way results for the most power possible.

The therory behind your car would be better suited for all around street/track situations where you have a more forgiving broader powerband at your disposal.

I appreciate both methods of power, they both have thier pros and cons. I'm sure you did make the right choice for you.

i would tear that 810 whp s2000 ass up on the street or track....im 1000% positive he would not beat me in any race

reason---when he launches his car the rpms drop drasticly. just hazard of the game....so by the time he spools. im gone and he is not catching up. he has to shift too much. his car also will prob break the tires loose really easy because of the huge spike in power. which is not good for drag racing. you want it to spike early then hold it. street or track...im taking his money

only one way to settle this, find that guy and race just get it on tape, I don't care who wins it'll be two fast as hell S2000's hauling ass

either way the topic was who has the most WHP with a stock powerplant (ie not a supra swap) and that's the highest so far.

look at SFWD guys running low 9's to high 9's on 72mm turbo's.....your telling me a s2000 is that much different that he can't do those times in a RWD.


Inline Pro did it with a 42r, did they not?

You are smoking some good stuff man.
