question about boost-a-pump
Alrite guys. Im a few month out from supercharging my car as i dont want to pull it all apart when this is the season for driving up here in new england. Anyways, i've been trying to gather as much info as I can and i have a question about the BAP that comes with most kits.
I know it seems like everyone uses the BAP and has good luck with it but what is the actual reliability behind it? Why would you take a fuel pump that runs off 12-14 volts and "boost" the voltage up to 17ish. Why dont a lot of people get a faster flowing pump that would keep up with the fuel demands of a FI car? Kinda like using the right tool for the right job?
I know the aeromotive stealth is out there and the walbro 400 i think it is.
Can these larger pumps still not flow enough fuel at the stock voltage levels that are supplied to the pump.
I know the cost and convenience of the BAP are attractable as they come with most of the kits but does anyone understand my concern here or follow my logic?
Any info/insight is much appreciated.
Thanks,
. Zac

How much power are you shooting for? If you are staying under 700 than a BAP should work fine for you, also it is only 17v when in boost, yes it's cost effective and will do the job, if your goal is big HP. Then yes might as well do a fuel system now and be done with it. I myself am at 755rwhp on a BAP and my fuel pressure never dipped below 57psi while on the dyno.

Im just gunna do a ecs or a&a entry level kit. I'll have full exhaust with LT headers.
I want to be close to 600 but more importantly i want to be over 500 tq. I understand that only in boost it ups the voltage but isnt that still kinda using the pump like it wasnt designed to use? I just feel a larger pump at stock voltage levels would be more reliable? Also, are you at 755 on stock fuel pump?

So i guess my question is if many of you could take the time to change the fuel pump would you or are you just as confident with the BAP as far as reliability?

I run a BAP with 725 rwhp and have no pressure drop. I do run a Z06 pump and a racetronix harness which help also. I would definitely recommend the harness if you do a BAP.

Yes, you'll be fine. I'd do the Racetronix harness like realcanuk mentioned. Lots of folks say the BAP's fail. Sure they do. The high dollar mega flow pumps fail too. BAP, done right, is pretty reliable.

Took 2.5 hours on my car and I was dissapointed it took that long. Next time maybe 1.5 hours at most as we had two issues. The pump didnt want to come out of the hole as if it was swelled and the plug on the pump was stuck and for fear of breaking it we took our time.
Its not that hard to do, not at all.

I certainly hope this is a joke. Do you have Stevie Wonder, Ray Charles, and Helen Keller working on it?

I've had the tank out and pump out in under 45 minutes on the drivers tank. If it is just swapping to a z06 pump/etc then that is pretty easy. Now if you have to drop the passenger tank too, put in a bypass plug/etc that is when it becomes much more of a pain. I guess I'm use to dropping both tanks. What you said it correct, to get one tank out and swap the pump is a few hours.

I'm running just under 600 rwhp with 8 pounds of boost in my 08 LS3 and installed a Z06 pump because my stock pump failed on the dyno. With that and my boost-a-pump, may I recommend that in addition you at least consider doing a Racetronix wiring harness. My stock wiring harness was failing me. I wish my original installer would have just done it properly right from the start. The place that I had install my harness says they do it will all of their builds. It is cheap insurance. Being told to put a 25 amp fuse in place of the factory 20 might work, but just seems like a bandaid solution to me. $200 installed for the harness just made sense. Why mess around!

The harness is a cheap and easy improvement to make and everyone should do it.
As far as tank removal, I believe it is far more difficult and time consuming on an automatic car.

BAP's got a bad name a while back from a particular brand that failed often, some even caught on fire from poor wiring. The BAPs we use with our std kit is pre programmed for your car and is cut and dry basically. I would not hesitate to use one in my own vehicle. I would have years ago.
