i have the ported eaton with a 2.93 and idlers and i want to break the 500hp to the wheels club. its putting down 489 now. i want to do a new upper and a lower pully setup. what can i do without having to change injectors and do i need to do a fuel pump if i change. i know i have to change my jlt cai to the high flow and just that may get me there but i still want a little more power
thanks, Erik
Erik,
I am running a Stage 3 steggy port. JLT fender kit, 2.8 upper and 2lb lower, accufab TB and plenum, borla stinger cb, and mafia. Kurgan did my car a couple weeks ago and it put 492 down.
I was running 15.5 lbs of boost and starting getting belt slip at top of run. (has metco 100 tensioner to help but still slipped) Bob said I was just about the end of stock fuel.
Could you squeeze an extra 8 out of it. Yeah i am sure, but the tune was safe and I don't have to worrry about it. If 500 is the number for you, keep the 2.93 upper and do a 4lb lower.
As others stated you'll max out fuel next after you do something about the MAF which is most likely pegged.
