It is usually suggested that the standard clutch will start to have trouble a little before 300 lb-ft of torque. The power isn't really the problem, it's the torque that kills them. That said with 300 bhp on what is probably a TD05 equipped car you are likely (but not certain) to be running somewhere around 300 lb-ft, so change gear smoothly and don't launch too hard. If you are running that level of torque you are also approaching the limits of the gearbox.

My UK MY00 clutch took 406 BHP and about 340 lbft (can't remember exactly now) and wasn't slipping after 31000 miles, although not all were at that power, most of them were well over 300 BHP.

Totally agree with John.
I would be temped to contact David at www.apiengines.co.uk for a price and fit an AP/Lateral organic assembly and never worry again.

Mystery,

My original MY01 clutch has done 50k miles and has been around the 330lb/ft for the last 20k miles.
This includes over 100 - 5k - 6k revs launches at RWYB days.

Still holding out (looks around frantically for some wood to touch)

Cheers

Martin
