BAP Installation with Pics

[JoeBoomz]

The comment a tad more you writeup is to install your BAP Pre FPDM my existing setup is After FPDM that's why I spliced into the pink&black wire that feeds the pump directly. What's preferred thou with a vehicle at 500+rwhp?

The concensus is that you wire the BAP before the FPDM, otherwise your ECU will not be able to control the fuel pump as intended.

Great write up but I noticed you didn't use a relay to supply the the boost a pumps power. Also I thought you splice into the pink and black wire or use that and the trigger for the relay. Anyone else notice these things?

The BAP will work off the stock wiring, however the BAP greatly amplifies spikes and droops in the current. For best results you should run an 8 or 10-guage wire from the battery for more consistent power. Use a relay if you want to maintain the fuel pump shutoff switch functionality.

For best results, you should use the output from the fuel pump shutoff switch to trigger the relay, and feed an 8ga wire from the battery into the relay to go into the BAP.

Run the BAP Pre FPDM. That way you can use a relay and separate power wire. Its how I'm running the BAP on our Cobra.

Why not just get a new 255lph pump, instead of "overclocking" an 8 year old stocker?

I'm "overclocking" a GT SuperCar Pump. Don't know how well it would work on a stocker.

In my case, the other option would be to go to a full dual pump setup and a BAP is much better route if you're under the 500HP mark.

Single GT is plenty of fuel for around 500rwhp mark

With a BAP, yes. Without, I was not getting enough fuel and I'm probably around 430 HP.

That's what I meant. Been there done that with my older car

Nate I keep meaning to tell you . You need to wire yours pre FPDM, cause your Fuel Pressure goes wacky when you step on it. Fuel pressure drops way down sky rockets then finally levels off. I'm pretty sure you can't see it on your FP guage on the pillar but the log I took you can see it. I'll see if I can get a screen shot of it. Your fuel pump is also maxing out at 5500rpm.

And a log of BAP pre FPDM.

Why would anyone wire the BAP post FPDM?

For some reason thats the way KB likes them installed.

Thanks Chris. Since then I have wired my pump pre fpdm and also upgraded the power wire and ran it directly from the battery fused of course. What do you recommend on my setup Chris? I have 60lb's gt40 pump already. Think it's time for dual pumps? If so will I need to add another fpdm and booster pump?

With 2 GT Pumps I ran out at ~540RWHP. I added a boost-a-pump

You added a 1 or 2 boost a pumps? Your current setup you have two FPDM's correct?

Natehawk, You don't need two BAP's. get a modded FPDM, 40amp BAP and a second fuel pump and you will be good on the blower you have now.

In doing my research I see a lot of people don't believe in that modded FPDM. Where would you recommend to get one? I see some people run dual FPDM where they grab one out s CV or GM from the boneyard for pennies. Also the data that Chris logged from my car was before I wired the boost-a-pump pre-FPDM, added in a relay and ran a 10 gauge wire from the battery (mines trunk mounted for a short run of wire), and shorted the boost-a-pump control wires to have it run at all times and not just on boost. All logged data was with post-FPDM and no relay with the bigger power wire. I think that alone may solved my problem. I'm going to data log my car this weekend it's suppose to be nice sunny weather.
