My torque is instantaneous and intense. I make 247lbs of torque by only 2700rpms It's an instant kick in the dick for my poor transmission...

yeah my last car was a supercharger gsr and the instant shock is tough on things especially on radials and w/o pre loading things break .I broke three axles in the old hatch and one final drive in it .So far the k series trans has handled everything I have thrown at it and that is even hard for me to believe as I know what its been thru

Stage 4 competition clutch and fly wheel

I have been slowly working my way up in power. I started out with a small boost setup at 278HP drove and tracked that for 10k miles.

Upgraded my fuel system and made 384HP. Drove and tracked that for another 9k miles.

I built the motor in Jan 2012 and finished April 2012

Made 421HP on 13psi

Did more tuning hit the dyno again and made 443HP

Ran this power level for 2 weeks about 1200 miles (Drove to tracks on the weekends)

Did more tuning and made 455HP/389ftlbs drove at this power level for 100 miles and broke 4th gear. Sounds like aluminum cans and rocks when I put it in 4th gear lol

I think my transmission problem was exacerbated by the fact my clutch was slipping. You would think the clutch slipping would help protect the transmission but I am thinking because it only slipped a little then it would catch instantly that put a shock load on the transmission. Like a 6krpm launch
