Default Can the stock pump keep up?

In an 02 Z28 with 36lb injectors at 58psi making 475-500hp is the stock pump big enough? I was asked this question the other day and didnt honestly know the answer.

I would say no.

I would just buy the Racetronix entire PnP 255 single pump kit, wiring harness & all.

it is worth it. direct bolt in once you drop the tank and it is a damn easy install & wire in.

Thats what I thought as well. Every time I have installed bigger injectors I have at the same time installed a 255 pump. I have never attempted to use the stock pump with larger injectors. Its my neighbors car and for some reason he balked at the idea of dropping the tank to install a bigger pump.

Can it be done? Im sure it can. Is it safe? Probably not. And do you really want to take the chance on something so absolutley important? I just look at it this way: a hotwire kit, and pump is a WHOLE lot cheaper than fixing the damage done from the stock pump failing to keep up!
