Car made 793hp and 737 ft at 18.5 psi, Still on factory headers and mid pipe with factory cats!!! Anyone else read this? I'm guessing another 50 whp with long tubes and off road pipe. Car went from 664/677 to 793/737 with TB MAF and inlet tube! this was all at 23* and 11.5:1 a/f. They said later on a colder day car went over the 800 whp mark. Damn is all i can say what kind of times you guys think this would run and how long will the factory rods hold up?
