Boost a Pump Question
Can I use a KB or MSD BAP with my stock 01 fuel pump or do need to buy a Racetronix or equivilant pump (is there a difference?) to use with the BAP. Looking to support about 675hp at 8 psi.
Of course trying to do this the cheapest way possible and still get reliable results......but if I need to go to a dual pump set up I will.
Want to pull the trigger on a purchase...but still unclear of which way to go.

Call Will at RSI and go with a dual pump setup. A single pump (even an upgraded one) with a bap is just not a safe option with that much power.
You wont find a better engineered or easy to install system. (my oppinion of course. )

Your best bet would be to upgrade your pump to the GSS342 or Racetronix and a BAP. You say 675hp, unless you mean WHP. If not, 550 +/- whp is no problem with a in the tank pump upgrade and a BAP. I would do the harness as well for an added level of safety. On my car, i make 650 +/- whp on a GSS342 and BAP with zero issues and a great a/f chart. I also have done this setup on many other c5 conversions. My approach would be to do the fuel system safely and put money elsewhere and eventually when you turn it up, go with the RSI. Either way, I can put a setup together for you so PM me your info (shipping zip) if you are interested.

On the new 383 motor we ran out of "safe" fuel at 4700rpm with stock fuel system. We made 575 RWHP / 556 lbstq at 4 psi.
To conserve $$$, was hoping I could get by with the pump and BAP. But that looks like I'd be pressing the limit with that configuration.....??

After reading your last post I would say to heck with saving some money. You need some fuel to keep that motor happy. Better to spend a little now then a whole lot later because running lean will cause problems, quick!!

I would look at getting the fuel pressure regulator up by the rails first. I think PeterPan is running stock lines from a 97-98 setup and pushing 750rwhp, I am not sure of the rest of his system but I don't think it is too upgraded (read expensive). The newer setups 99-up run the FPR with the filter and they have a lot of trouble keeping up.

Ive got a few friends that replaced in tank pumps with aftermarket and have had problems (dont know which brands though but they all had problems with pumps going out).
Id rather do a external system and have quick access to it if there is a problem and even if there is a problem the car will still run perfectly with the existing stock system and get me home instead of being dead on the road somewhere with in tank upgraded pump problems.

I only use a BAP and Racetronix hot wire. The stock pump in my 03 Z works for me with >700rwhp. Yeah my fuel psi drops but it's compensated by the tune. My AFR's are good, and thats what matters right?

Just thinking out loud here ... how much does a set up like that run...

You would have to contact Jeff at TPE or Will at RSI for current pricing. We purchased the fuel hat only as we had the rest of the system already upgraded and just wanted the perfectly designed pump hanger. I believe they are offering a FULL fuel system now with everything you need front to back. Its not cheap, but quality never is. And let me tell you, this setup is QUALITY!

My setup has been together for 4 years with the 97-98 GM setup with a KB BAP, LPE intake fuel pump with 60# injectors and it works just fine so if you can find this setup it is inexpensive and works for me. Note I have mine setup on boost reference, 48 lbs at idle or no load and 58-60lbs under load or boost
