Cause Dave is REALLY picky about what he considers a street car. I know he'd find some excuse just as I would if I lost to ya and you were spraying. I know he'll want us to run with 93oct and no nitrous before he'll admit our times as being officially the faster street car. O well. IMO if everyone uses 116oct etc then why not go ahead and use it? Its so much more fun using it and if the playing field is leveled then it isnt cheating
