Not so sure that would have qualified as "fun run", sweat was running at the end of the race. The cobra plus bumpy track makes for hard work, so may areas that require a light tough on the throttle.
Finally got some pace in the last few laps, as if something just clicked and the car started flowing around the corners, should have hanged in there Viper
But Wally had this one easily in the bag, faultless and quick, nice driving.(ps, your result links are busted Phil)
