Ive been following that thread. I trust what Bob says 100%. The only downside I see to pushing the 80s so far is the fact that in a return type system you have to remember the regulator also ramps the fuel pressure 1;1 with boost. So if you have a base 70 psi fuel pressure and are running 25lbs of boost now your at 95 psi fuel pressure. To much for the hoses and pumps in my mind. Will it work? Yes. Will it last? \..........? Ive already lost one big motor in my friends vette because a hose split. I am a big believer in the KISS philosophy.
