FAST PORTED to a FAST UNPORTED? ? ?

What is the approximate hp gains as porting the Fast 90/90 setup. i heard from a friend about 10/15 hp. Is that true or just a myth?

We have seen anywhere from 5-14rwhp increases when doing our portwork to a FAST 90mm manifold. Depends alot on head selection and maximum RPM being turned.

if you can spend $1200 on a FAST 90/90 to gain 20hp...why not spend another $250 for the porting and gain another 10-15hp?

78mm FAST intakes are a waist IMHO. if you're gonna blow the money, go 90mm. i ported mine for FREE, less the cost of sanding rolls. went from 393rwhp through factory 10-bolt to 417rwhp through a 9".

there's a few threads on here about how to port a FAST yourself. Our sponsors know a few tricks we don't i'm sure, and have flowbench access, BUT there are several places you can easily work one over yourself and get SOTP gains
