Whipple 416....
The plan was setup 2 tunes, 1 for each pulley. 3.75 and the 2.75.
Long story short, we didn't have a short enough belt for proper tension on the 2.75 and it shredded...lol. That pulley would be good for about 16 psi. So we only got to setup the 3.75 which is only 8psi.
It put down 661 on 8 lbs at 6750.
Car had gone 9.84 at 138 before the can swap on 8psi. Hopefulley the belt will be here Friday to setup the tune for the big boy pulley. I'll post a quick idle vid shortley.

Also, I'm curious about the boost and pulley size you're running. On the Whipple site the 3.75 pulley should produce 11 pounds at 6500 rpm and the 2.75 is 19. I am running the 3.875 on a stock bottom end and am making pretty close to what whipple says I should be (10 pounds).
Interested in getting my mind around why there is a difference. I assume that the extra cubes and cam, as well as, head work and opened exhaust would account for this. Correct?
