[gringo76]

doing a e85 conversion and trying to nail down a fuel pump. good rods and pistons, vortec heads, 80lb injectors, 63mm precision turbo. been looking at walbr 405 and 450.
which one do you think will support my set up. will be upgrading lines.

Re: fuel pump

I'm running e85, stock lines with a Walbaro 450. With a pte 54 turbo and stock heads and internals my duty cycle was at 80% at 18psi of boost.
