Hi Ray, Erik. I would add one thing more if its OK. The racetrack and the street are 2 different realitys. Taking a race car onto the street requirea all kind of compromises, and trying to run a street car against purpose built racecars is like a 1 legged man at a [well u get the drift]. We all want to think we have a special kind of car for our own bragging rites, and thats a big part of the fun, as long as we keep it in perspective. Race engines work best on the track and any attempt to put them on the street compromises all the engineering genius.
