Well there is a Gary Dares running a 383 Chev powered 1200 Sedan at Powercruise 7. I have posted a couple of pics in the gallery, some other cleverer bugger can link them to this subject. It looks like a nice car, but I would have built it a little lower , my taste though! As for his theory on vehicle dynamics he needs to reread his mechanics textbooks.....the front spoiler will help direct air around the front of the car and stop air running under the car and unsettling it.The rear spoilers is really only for looks and will only start to work at higher speeds. The flares will be helping redirect air as well. As a power man I am sure he has checked out the wheel wells of the top doorslammers and funnies to see how subtle changes make speed.
