Supercharger Question?

Cameron · 05-20-2004, 09:58 AM

I have a friend with a 90 GT. He runs a Procharger with an intercooler and is having a small problem. The car runs good till you hammer it or down shift and hammer it. It wants to spit and sputter or cutting out should I say. It doesn't do it if you ease into the throttle. Only when you put the hammer down. Thanks Guys.

Do you know what his fuel pressure is before and during when the gas is mashed.

I don't know that right off hand. I think he runs about 45psi at ideal. I also believe he runs 36 pound injectors. Sorry guys I don't know a lot about the car.

Sounds like a LEAN Spike. How is the car tuned. Chip, Tuning Device(Tweecer,PMS, Etc.). He probably needs a tuning session so that a wideband can watch is fuel mixture.

If he is running an FMU it also may be going rich on tip in.

He figured it out. It is blowing out the spark, so he needs to check his plug gap.
