fuel problems after whipple dyno

[RiffRaff04]

Finally got the whipple on and dyno'ed but one thing my tunner noticed was that I was running out of fuel past about 5700rpm. He said that my twin focus pumps were maxed out past there. What would you guys suggest to fix this without breaking the bank on another fuel set up?

either a bap or upgrade the pumps to ford gt and a modded fpdm.

bap and add a return line

Somthing is not right I am running the same setup as many of my other Cobra friends and I have pleanty of fuel, on the dyno I was pig rich my tuner had to keep taking out fuel 580hp 540tq A/F at 11.4 up top conservative, street tune. Mac o/r prochamber and mag cat-back 3.0 upper pulley stock lower. You should be good to go try a different tuner.

i was 90% duty cycle so i added BAP with modded fpdm to be safe and that with a ported eaton,so it happens . so for 550 bucks your back in bussiness

BAP and wiring upgrade.(to pumps and BAP)

This would work with just stock pumps too...

I also removed my PPRV while I'm in there.(still currently underway)

The PPRV is a big restriction and has been proven to contribute to....... if not solely cause the dreaded between shift hesitation.

BAP and wiring upgrade. IMO the focus pumps are a waste. You can get by with more power on the stock pumps with a BAP and wiring upgrade. Now, the FGT pumps are a different story.

I am on the stock pumps with the bap and wire upgrade. I am running 17 psi with a new tune (done on 6-06-07). My A/F is 11.7:1, and my duty cycle is at a max of 82% with the BAP set to 40%. I still have a lot of room to work.

I don't get this. I am running 19 psi on twin focus pumps with no problems. Am I missing something?

 

[mixxer]

every car is different fang, ive seen a bunch of 600hp cars running focus pumps with no problems and other that cant.

 

[RiffRaff04]

You guys think I can get by with just BAP??

 

[mixxer]

no you need modded fpdm with bap with focus pumps.

 

[unit213]

no you need modded fpdm with bap and focus pumps.

Really? :shrug:

My fuel mods(at this point) consists of a BAP and 55lb injectors.

My 2.2L KB is at 19psi and it makes over 600rwhp.

 

[mixxer]

unit, he has focus pumps you have stock pumps.you shouldnt run BAP with focus pumps unless you add modded fpdm. stock pumps and BAP is fine.

Hey Daniel...... I can attest with Hissman, I have the same setup and no issues... BAP and WIRING upgrade is the key.
