I had a Viper guy at Road Atlanta tell me the same thing. He was explaining to me how he would pull on the Vette. Unfortnately, we were running in different groups, so we were not on the track together. However, once he heard the Vette scream by pit road, he came over when I pulled & asked, "What to hell do you have in there?" I opened the hood & he said, "Forget what I said before."
