Re: Fuel pump questions

I just read on 3 different boards people were achieving 700+ with 255 Wally's in parallel. So I'd try your pumps first. Then go from there.

My car already put down 760ish awhp at map with these pumps, 1650cc injectors and the base fuel pressure at 54psi. I now have 2150s and the fuel pressure down to 40psi so that should help. But how much more do these pumps have in them? I've read a lot of threads saying one wally 255 can support 450-500 on e85 so in theory 2 should do 900 to 1000.if that's the case these should be enough.

I am currently around 650whp and I am out of injector right now. I am going with 2150's soon I think to solve that and hopefully I can get my fueling under control. If I run out of fuel still after this then I will simply run a BAP.
Okay thanks! That's good to know.

Now what I would like to know if anyone can answer can you run one pump that is larger and one that is smaller when the pumps are set up in parallel?
