Default what size TD's for 450-460 hp?

as the title says? what size pipe for 450-460 rwhp?

in the future in going H/C... custom comp 228/232 110 cam, Dart or AFR 205 heads and a 90/90
is 2.5 inch pipe enough for a zero lose system?

definitely go 3" 2.5" is just to small. With that kind of power that car is going to want to breathe.

Free flowing 2.5" duals will support a hair over 500fwhp before they become a restriction. Anything over that and you should be looking at 3".

I think dual 2.5" should be able to support it. Where's that formula for calculating hp vs CFM flow in pipes...that's what we need for this.
