I do not own a Backdraft but I did sleep at a motel last night.
Actuall I have had the pleasure of meeting Reg Dodd of Backdraft and saw him run at a couple of our Deep South Cobra Club events. He brought a new model Backdraft with the M3 suspension and it was running a 400plus C.I. stroker with about 500hp. This car was scary fast and simply overpowered the Kumho Victoracers he was running. At first I thought the engine was smoking but it was smoke from the rear tires. It did this for several hundred feet past the corners at Gainesville road course.
This was not a big block but it did have awsome Torque. Another guy had a backdraft with a built 302 and he actually was the fastest car due to his SCCA background. He hopped in Reg's car and did run faster in it than his own car which had spun it bearings(High volume
oil pump was the suspected problem)
IMHO the backdrafts are not quite the car a SPF is but they are great looking, handle great and a great value. They do have a 92" w.b. so they have a slightly different look to the side profile but the average person will never pick up on it. They do have a lot of room in the cockpit so if you have long legs that is a plus.
Reg is a great guy and he took care of the customer who had the engine problem.
