I would have to say its Nascar Jimmy I met this guy through all the local car shows he started in Nascar 30+ years ago sweeping the garages out and retired as a head official. He has a Lingenfelter one off twin turbo C5 vette convertible. he had this thing when the C5s FIRST came out and there was no convertible. Dale Earnhardt drove his vette around Daytona at 220+ MPH. im not sure of the exact setup but it is MEAN he has 8 sec time slips he says were with the AC on and this guy is OLD and its an automatic!
