My rx-7 is stock but has cold air intake quiet muffler. I had a full 3"exhaust w no cats last time I went to the track 6year old tires. Boost is 11psi. This car could lap faster than the LT-1 93,94 ZR-1 (Slightly modded to 440HP according to the owner), 5.0 mustang. The gearing in 3rd allows about 110mi/hr and I had to hit 4th on the top end of the track at Holtville. I could carry more speed coming out to the straight than all other street cars. The ZR-1 could pull slightly more during exit but I was even on the top end and I could delay braking and would shoot by at the end into the sharp turn after the straight. Braking at 115mph and handling easly makes up a tenth 0- 60 accel.
balanced performance and light weight = greatness at any price
