Maxed out at 4000 rpm's

[swordfish]

Took the car to the dyno yesterday. Said the fuel is maxed out at 4000. Ive got the GT super car pump with a BAP with 42lb inj. He's telling me I need 60lb inj. This is same set up the other SC Marauders are running. So my question. What else can it be?

what are the mods how many hp/tq before you ran out of fuel

First check the bap is putting out 17 volts.
Next make sure the alternator is putting out proper volts at high.rpms.
if that stuff.checks out time to.go.back in the.tank ans fix whatever is wrong.

This is assuming you have a new fuel filter on the car.

You don't need 60's. When tuners tell you.that its probably time to.go.elsewhere

Stock motor with Eaton, 420hp

Put on a new filter, will check out the bap and alt this weekend.
Thanks!

I went overkill and I'm running 60's and 2 Ford GT pumps.

Something is definitely screwy with that Mark. Mine is only a Walbro 342 pump, BAP, and 39#ers and FPDC is no where near maxed at 445 RWHP.

I'd check the BAP first.

He told me its the BAP, unsure though if its a wiring problem or the dial at this point.

Had the same issue with mine. I'd purchased a used BAP, was only putting out 12 volts, swapped out with a new unit, problem solved.

Did you install.a.new bap and dial? Or just.the red.box?

New bap and dial, after the the install, 17+ volts, life is good!

Do you know if used BAPs can be rebuilt? If so, I have one available.

BAPS don't go.bad. Just the dials.

My bad!:-o

Are replacement dials available through Kenne Bell or elsewhere?

Yep, for $25 shipped IIRC.

You can also splice into that wire with the RCA end and simply connect the + & - and the BAP would put out max volts at all times.
