just wanted to know how much power will a stock tpi camaro fuel pump suport befor stepin up to a high-flow pump?

 

i dunno but fuel pumps can be a nice upgrade got my car down 14.6 everything stock

 

what pump did you put in?

 

A walbro 307 255lph pump is good if you're running N/A, if you're running boosted I'd probably go with the 340. The Holley in tank pumps summit/jegs sell are pretty much a re-labeled Walbro from what I've been told. Should run around 130 give or take with the install kit. Another pump that the Buick guys use is the Syclone fuel pump, if you're looking for something "off the shelf"

 

so this Syclone fuel pump will be just fine for a N/A motor....and what if i go boosted down the read will it still work? and they will fit and work just fine ...like a stock camaro pump? how much cheaper are they from NAPA or a place like that to a walbro 307 255lph pump.....

 

They're about $60 by themselves if I remember correctly (the Sy pumps) but you'd probably want to replace your in tank harness too, and replace the piece of rubber hose and need a new tank seal, etc. so by the time you're done you're talking about minimal savings.

This is the racetronix kit which is a significant upgrade in the harness as well, I built something like they did using an old relay socket and a fuel pump relay from a JY harness. The Buick guys call this "hot wiring" the pump. The big deal is that the main run of wire is #10 to the alternator terminal, this can be worth significant capability in the system because the voltage doesn't drop off at load. The old fuel pump wires are used to turn on/off the relay which in turn turns on/off the pump. I believe they also run a heavier ground as well, but don't me to that.
The difference between a 307 and 340 is largely how much boost you can run, because you have base FP+boost level, the 307 bypasses at ~60 PSI the 340 doesn't. That means assuming a 43 PSI base ful pressure you could run ~17 PSI boost. The 307s are good for about 550-600hp generally, so unless you're running a super racey setup it should be a good pump.

This is $99 with the install kit, I'd call up and ask but it should fit your application as well. You can't go wrong with Mike, he's a good guy. For the extra $$ I'd just get the Walbro btw.
