These pics are from the 2000 NOPI Nationals at the Atlanta Motor Speedway. I was there working, and I was able to get away just long enough to get a baseline on my truck. I did one run wit hthe truck in bone-stock form, and the other two with the air filter cover un-done so as to by-pass it. Look at the gains by doing just that.
