I have a 2000 Civic Si with a drag turbo kit with the 60 trim and tial wastegate upgrade. I have 600cc high impedence injectors, stock map sensor, on Hondata s100.

I went to get the car tuned on friday on a dynojet dyno. On 9psi the dyno read only 165whp. The graph was really smooth going all the way to 8K. I dont think that their wideband was working 100%. If the clutch was slipping, then the graph would be sporatic, right?

Im just trying to get what i was expecting out of this kit. I know it can make more than 165whp.

Thanks if anyone could help out.

 

On 9psi you should be making around 260whp.

Your injectors are a little big for your setup, although that shouldn't hurt you.

Do you have a fuel pump? Who is your tuner? Stock exhaust? Stock clutch?

I miss my drag kit so bad.

 

2.5 greddy evo exhaust, stock fuel pump, stock clutch. AA Autosports tuned it.

My Si only has 82,XXX miles on it also..

 

Boost leakage.....

 

the boost was holding to redline. I will double check the clamps.

any other ideas??

 

I'd get rid of the stock clutch and fuel pump.

Whats the a/f look like and timing maps?

 

stock timing i believe... i didnt get a printout because it was almost 12pm and it was only like 165whp.

 

who is tuning it?

get a walbro fuel pump!

 

I wanna say the guys name was Dave that was tuning it. Do i really need a Walbro pump for under 10psi?

 

with that size injectors yes you would need one or i would be a good idea
