update on Sierra's Rx-7, i fixed the boost leak and dynoed the car at 9psi. car made 280rwhp, anything over 9psi and it would lean out real bad so i kept it at 9lbs of boost. we took the car to our local race track and she ran [email protected] with a 1.7 60ft mark

here is a video of her 12.8 run, the loud noise behind her was a rotary powered toyota starlet also testing that day.. on this run you could see how she over revved it,(between 2nd gear and 3rd gear) hitting the rev limiter and slowing the car down. this Rx-7 has more in it.
