Andy recently got rid of the 2008 A6 and replaced it with a 2007 Z06. It made 445 RWHP, bone stock. About average for a C6 Z06.

With a Calloway Honker cold air intake and custom tuning it made 483 RWHP and 448 RWTQ.

The guys in the shop installed one of our new blower cams and a set of 1 3/4″ American Racing Headers and it made 535 RWHP and 505 RWTQ.

Impressive. A major improvement over stock. It had a very nice little lope at idle and had absolutely no bad manners in traffic.

This week we installed one of our standard supercharger systems. It is an SI Trim with a 3.8 pulley. I didn’t upgrade anything over what comes in my standard system. It made 665 RWHP and 625 RWTQ with only 13 degrees of timing and about 6 1/2# of boost. And that’s on 91 Octane California gas.
We couldn’t be happier than that.

Here are the 3 HP and Torque curves. The stock curve is not on the graphs.

Stay Tuned for a T-Trim upgrade!
