on street tires weighing in at about 3400 i pulled a 12.1 @ 117 mph.
Its not unbelievable for him to pull them times, you just spend more time on weight reduction and traction over the motor aspect.
11.87 and 118 are hand in hand 60whp is a bigger difference when you are talking about cars that have no weight on them…
what kinda times do you run now?
