Done in Santa Rosa, California (northern) at Black Sheep Performance using a new-model Dynojet. Block is a mildly ported S4 turbo block with aftermarket flywheel and Ser 5 crank assembly (9:1), Precision Turbo PT67 w/ a 0.81 A/R P-Trim hotside, 680/1680 injector combination, 23.5 to 24psi of boost steadily on 111 leaded octane fuel. Tuned by yours truly.



Pictures and videos of the car can be found at:

Fikse -- Close to 90% at that point. That's one reason why we shut it down.



Vosko -- Jim's car made 417rwhp at 15.5-16psi.



L8t -- Yep, of course I can. Carl's S4 block was unpinned.

thats pretty cool, a little low on torque though, would love to see a rpm graph instead of mph to see how the spool is

B, how would you rate the "aggressiveness" of the tune? Is there room for more HP @ that boost level?
