I don't race the car as I don't fit into any classes. Any class that allows two power adders, is going to have people FLYING. They also will weigh a lot less. I'm over 3800lbs, it's a pig. Since my car is a street car first and track toy second, the converter is mild. My car has been 7.80's at 184 with previous owner. That was with a different converter, cam and intercooller. Could it be driven on the street, sorta. With slicks, my car is only worth an 8.50, which just isn't competitive in most classes. Between the weight and the converter, I'm just not fast enough. Which is fine with me. I have a purpose built street car that just happens to go fast on the track. There is another viper out there, Sal's, that runs some Drag Radial stuff. His car is street legal and runs 7.50's. Super nice guy.
