Boost A Pump ?
I have installed a twin screw Whipple Supercharger on my 02 vert. The HP is in the 500 range. A Boost A Pump came with it. Should I use it, or install an in-line pump. What recommendations if I decide to go with the in-line pump? Also, if I go in-line, do I leave the pump in the tank alone?

If you want to know if you need the BAP, you can dyno your car with it hooked up to a tuning program. This'll let you know your fuel pressure as it's revved up, under load. A real good bit of knowledge for safety's sake.

I don't think there is any doubt you will need it if you decide not to do anything else.I don't know the difference between your pump and a stock Z06 pump.Chris Stewart makes over 700RWHP with a BAP and Z06 pump.I have heard of some BAPs failing and if that happens under boost it may hurt your motor.
If you have the extra money it would be a good idea to put an upgraded fuel system in the car which included a high flow pump.The Racetronix pump worked well for me.It came complete with the factory bucket so installation was simple.If you plan on making
power in the future then go to a return style system and save yourself the time and money from redoing it later on.
If you decide on an inline system then leave the stock system alone and put the inline pump on a Hobbs switch.That way you will have no priming problems and the stock pump will give you extra fuel.
Good luck.

Agree!

. One point to note about potential BAP failures. KB sells a 20 and 40 amp version. When I asked KB which I should purchase, they strongly recommended the 40 amp version.

Hmmm. KB recommended a 20 amp for me when I was at 600 rwhp and thats what I had on for a long time before going to a A&A fuel system when I went with more boost. I never had a BAP problem with the 20 amp one though through 12K miles.

I am running a BAP, 255 Walbro, stock fuel system, 42lb green tops.
BAP only active when spraying (so it's not boost) and about 700 rwhp. I just use it to make sure (hopefully, lol) FP doesn't drop under load.
