We're proud to announce that the 2.9L Whipple Supercharger for the 07-09 GT500 is alive and well. Recent testing at Whipple's facility showed just how potent the 2.9L is. On an almost stock car the 2.9L made 676rwhp at 16.5lbs of boost.

108 IAT2, 159 ECT, Dyno temp (right next to car) 93.36deg F, 29.87in-hg, humidity 12%, SAE 1.00. 20deg timing. Dustin's going to try going to 11.8 (now between 11.0-11.2) and 1-2deg more timing to see how the car reacts.
