Ford GT Dyno Runs at Carlisle PA June 7, 2008. Most GTs will put out ~535 whp right out of the box. This car has a 2.7" supercharger pulley, long tube rear exit headers and has been tuned. The result was 555 whp which indicates a fairly significant dyno calibration issue.
I didnt ask what correction factor they were using, but it was like 1 million degrees up there this weekend. That could be it ?
