Well, the kit makes more power than the stock Exedy clutch can handle!

Surprisingly, the car still hit the advertised peak numbers (430/400):
- 427 whp @ 6220 rpm
- 406 ftlbs tq @ 4270 rpm

It could have made more, even with the stock nismo exhaust, on pump 91 octane, with the cats still installed, but we found out that hard way that the Exedy clutch is only rated for 383 ftlbs torque. The power curve hits that and the clutch slips. It’s still totally drivable day to day, but it slips if you floor it. Honestly, I drove it around town for a week and never had enough road in front of me to floor it, so I didn’t notice. But I’m probably gonna have to get the JWT clutch, rated for 600 ftlbs, to get full value out the kit, especially if I want to track it.
