RWHP/RWTQ: 475rwhp / ~ 440 rwtq

Installed: August 2008

Approximate miles since installed: ~10,000

Issues since install: Originally the kit seperated my stock crank pulley/harmonic balancer after only a hundred miles or so (with the stock pulley it was making 428 rwhp / ~400 rwtq @ 7.7ibs) . Replaced the harmonic balancer with a much more sturdy looking Summit version based on pro-charged friends recommendation. No issues since - just had to buy a longer belt.
I have been shredding belts. I'm on my 2nd tensioner (original stock tensioner pulley started to wobble around 18k miles) and my 4th belt since October. The outter edge starts to fray. Going to try a new tensioner/idler pulley and a heavy duty belt next.

Driving habits: Weekend driver, Monthly AutoX, aggressive street driving.

I'm nearing 30,000 miles on my car. The KB was added around 10 or 15k I believe. Everything is still fine on the motor =)
