So my dad talked to Williams Performance today...they said that got 393 HP on four pounds of boost with the fuel system maxing out at 5500 RPMs, think I'm getting an aftermarket fuel pump in the next few weeks and going for 5-6 pounds of boost. I'm hoping for at least 410 HP.


This is on an all stock motor with the base STS kit plus an FMIC by TRT.

Sounds like it's coming together. Are you running the stock fuel pump and injectors?

jeremy02

I was suppossed to get 42 pound injectors, but I instead got 30 pound ones(mix up), if they an't tune it well enough with the 30s, we got word that the guy will send us the 42s we are owed. Stock fuel pump.


I'm excited.

i don't know if I'd run it again until you upgrade the injectors... I would hate for it to go lean because you're running too small of an injector...

jeremy02

Wideband has read lean about 700 times since it was installed and I haven't had anything(that I know of)go wrong yet. Noone is touching the car except for the tuner until it's right. I'm leaving it there.

Picked up my car today. Boost guage still reads four pounds and they got it to 402 HP.


Racetronix fuel pump and 30 pound injectors.

Im guessing those poor little 30lb'ers are running at over 100% duty cycle.

jeremy02

Nope. I'm not still 100% sure that they're 30 pounds. I was suppossed be sent sent 42 pound injectors, and I thought that's what was on the car, but the people at Williams said they were 30 pound injectors.


Car doesn't go lean at all.

nice! throw in the bigger ones for some safety, and for when you up the boost!

Yeah, I'd hate to see you just guess and cross your fingers, ignore the wideband and have it blow. It's not like you'll get a few warning messages first.

Thanks for the tips...but I sure don't ignore the wideband. My car was tuned at Williams Performance...they're great and said I'm perfectly fine.

I thought people make 400hp on stock injector's with head's and cam setup's.Do you have a FPR?

They can make more HP on a given injector NA because the Brake Specific Fuel Consumption is lower than on a supercharged or turbo setup.

Cool! I have never done a N/A setup,so that's useful info. Thank's!
