ok guys got dynoed on 3/24/09 at churches tell me what you guys think
havent even try to run the car at the high power levels yet but pretty happy with the results so far.

specs: H22a4 88mm
CP pistons 9.0:1
eagle rods
stock head with supertech valvetrain
skunk2 intake manifold
hondata intake manifold gasket
PWR intercooler
precision GT35r T4 .58 A/R
3inch vband dp crush bent ghetto fab.
3inch E cut out exhaust
last run high hp was on c16
1000cc precisiion injectors
255 walbro




tell me what you guys think of the power band and what not thanks
oh yea and the last high power run was at 25 psi

Pman92

Sounds kind of low since I made the same power with a 60-1 on stock head at 27psi 1000cc injectors. Same pistons and rods. c-16 race gas. What size down pipe and what type of mani?

Mikey3000

i agree with Pman92. that seems like a low HP number for 25 psi. good torque though. you must have a restriction somewhere.

The graph resembles non performance

As long as you're happy, and it drives fantastic for you, who cares about the numbers..

thanks guys youre right it feels awsome especially the response its insane i cant go straight lol

Nice numbers mang! I bet its fun.

You should post in the High Horsepower H-series thread.https://honda-tech.com/forums/forced-induction-16/high-horsepower-h-series-thread-1833278/

vtec is a tad to early

superturboprelude

will 15inch accord wheels clear my calipers guys? or prelude wheels or what 15 inch will be good i really need drag slick.

superturboprelude

Some one was sayig restriction some where. can it be down pipe design? It's 3 inch

custom specs?? whats that mean.. its dumping torque hard up top somethings not quite right what muffler do you on the car...

I made 604whp on 28psi on my 35R with a stock head

2point2

Who did the sleeving?

superturboprelude

as far as custom specs its .58 a/r T4 gt35r with stock head and i am running a qtp cutout 3inch with the rest of the exhaust goin to a 2 inch stock prelude muffler. Also can you please specify on how it is dumping torque hard up top? also can you show me your dyno graph i would like to compare so i can fix what is wrong with my power band thanks.


also it was sleeved and built by laskey racing

nice numbers. must be crazy on the street.

Your torque is falling off rapidy after it peaks, is boost steady?

Its making decent power but something just isnt quite right, powerband should be better and hold out longer with that snail

superturboprelude

you think its becuase im running a T4 .58 a/r housing on that 35r? but here i think this is my problem and yes my boost stayts constant to 25 lbs alll the way and it hits full booost by 4700 rpm

Tony the Tiger

Crush bent downpipe sure isn't the best, and the MIG welds could be potentially full of slags inside the weld joint... A T4 0.58 A/R isn't that small, but I would go larger because you have a bigger motor than most of the B-series guys and you shouldn't follow their footsteps in terms of choosing turbine size. The fact that your torque curve looks almost identical from low boost to high boost doesn't really point to having a small turbine or a restricted downpipe, etc..

How's the boost curve?

If boost is holding solid all the way to redline, then there could be a timing problem somewhere; either ignition is not getting full advance, or the cam timing is off and shifted the powerband.

superturboprelude

Ok I check my timing they are dead on , and my boost stays constant from 4800 rpm all the way till redline. Only thing I can think of is the exhaust system isn't efficient. Anyone else?

B20luda

looking at the dumptube... i bet your turbo was injesting some exhuast from the dump... try and reroute or extend it else where next time your on the dyno

also your cutout is going agaisnt exhuast flow, getting a manderal bent Downpipe and fixing that cutout might help as well

superturboprelude

For the cut out what you mean by it's goig against the exhaust flow? And yea I am going to to redo the downpipe for sure and I see what your saying about the dump so you think the turbo is sucking in hot exhaust gas from the dump right? Thanks any more suggesttion? Also do you guys think I should go with t4 .82r turbine because I'm goig to redyno for 600 hp this any other suggestion thanks ?

LightningTeg

These were done with the cutout open Im assuming

superturboprelude

What size turbine were you using? And size dp and exhaust ?
