Bullitt intake with blower
 

If you have a centrifugal supercharger on your 2V-4.6, you may want to check out this month's MM&FF. It looks like if you have a blower those larger diameter, shorter runners really shine.
They took a basically stock 99+ 4.6 2V (just had a 70mm TB) with a good size centrifugal blower (some kind of Procharger I think, might have been a P3) and custom fuel system and added a Bullitt intake manifold. The dyno came back with a 35hp increase and 45 ft-lb more torque - 561rwhp.

Mine goes on in a few weeks except my car is NA.

561 RWHP!?
I'm going to have to buy the issue just to find out what OTHER mods they have... They must be runnin some tremendous boost.

And I hope they've built the bottom end of that motor!
10 pounds of supercharged boost is iffy, and 12 or more....
Well, I hope they have an engine rebuild planned. :)

561rwhp:eek:

Hammer,
It's Jimmy V's car with a ProCharger. I really don't think the term "otherwise stock 2V" applies to anything he owns!
