How much h.p. can you sqeeze out of a supercharged setup with #60 injectors a bap and a stock fuel pump typically?

clemsondave

You will run out of pressure before maxing out the 60's. With bap and stock pump, you will max out around 550rwhp (with 42s or 60s).

550-575 w/stock pump.

With LPE pump, you can push it to 650rwhp.

On mine, with a Bosch 420 intank pump, I pushed mine to 802rwhp/ 851rwtq.

Stock fuel pump, KB BAP, 42# injectors @92% duty cycle. 596 RWHP

But this is with Methenol,right? Could be very misleading.

I run 60lb injectors with stock pump and BAP to about 600-650rwhp. Mind you this is tuning the fuel pressure drop.With no drop you could probly hit 750-800rwhp.

I run a ECS novi with ECS installed 60 injectors with a MSD booster and I have 581 rwhp and guage never drops off

I've got the A&A S Trim kit with the 60lb injectors and new fuel pump (I think it's an LPE) that comes with his kit and got 563rwhp on Andy's dyno and 561rwhp on Charlie's dyno (with a slipping clutch). I had Charlie re-dyno/tune it because a couple of times running on hot days I got what sounded like knocking when pushing it over 6000rpms.

Charlie saw the fuel pressure dropping to 40lbs on the dyno so he is installing a Boost-A-Pump right now. So I can say this, even with A&A's kit that includes a new fuel pump if you're anywhere near 560rwhp you will probably need a BAP.

No meth, I was wondering because I'm running 520 to the wheels now on 5 lbs of boost and was curious if I could run the 7 lb pulley and still have enough fuel capacity.

In an 00 Fuel System ,I asked Ecs the same Question ,His Response was, 525-550 is about the most I would push the system to be safe

SuperZ1

Correct, that is with methanol. I have no fuel pressure drop.

Slowhawk did my tune, i have the 60# and the bap and i dynoed 643rwhp

I am running 800 rwhp with 60# injectors, BAP, and Racetronix. Fuel pressure would drop at the very top. I am in the middle of installing a Stage 2 ECS fuel system and will continue to use the 60's for now but may have to upgrade due to a couple of other changes I am making.

I think it makes a difference if you have a return style system as well. A returnless system will show a pressure drop sooner than a return style. That is what we have seen

i have 60# injectors, and a kenne belle boostapump, and im making 650ish at the wheels. I need an upgrade return line system, whos is the best? Im putting in a single pump, im sick of this boostapump multipump nonsense... i just want one big pump. Any advice?
