Is a boost referenced FPR required on all builds or just the big ones?...
(im only looking for 450-500rwhp to start with)
ill be running dual walbro 255s... to a T70 Manifold Build on a stock long block... will I need a FPR of any kind or just run it direct?...

If one is required...what do you guys recommend for this mild build?...

you can use the stock FPR. and unless your planing to up the HP soon, id just stay with one walbro, should be plenty for the power you are hoping for.

hmm.. You think one pump will flow enough?

I am interested in this as well. I was under the impression I HAD to get a boost referenced fpr. I have roughly the same hp goals as the OP

A single pump with a hotwire kit is easily good to 450-500.

while the BR fpr is not required, it sure would help. When I had the stock setup, my fp would drop 8-10 psi at the rails when in boost. Now, it doesnt go below 50psi and even rises with boost pressure.
