do you need twin fuel pumps to get over 400 bhp ?
i am building long studed bottom end , pocketed mahle pistons , ported & polished head
.Swedish inlet with 68mm throttle body . t4 & greys & p8, with as much boost as fuel will allow .
i have only got an uprated in tank pump at mo . was hoping to acheive a reliable 400 bhp .
what do ya think ??
