Nice RL have you had it on a dyno? I have been thinking about replacing my SL with a Used Red Line and I was curious what one with the comp package will do. The one Sport Compact Car tested in 2004 put down 197 wheel hp which gives the car way more than the GM claimed 205 crank HP. It probably has more like 230-238 crank hp in stock trim.
