I have this engine on my r12 with a novamega tp-04 tuned pipe and the car runs exellent. I had to change the gear ratio because the car had too much power on the low end. My lap times at FTSPEEDWAY are faster than most of the mugen and serpents using mt-12 and sirios. The straight at FTSPEEDWAY is 280' and i have plenty of power. You wont be disappointed with this engine.
