Yep, that's why manual cars can overboost in 6th gear at full throttle at 2000RPM. High load.

thanx

I agree with what you say Ive always been taught if I had 3.7 I would have more torque than I would with the 4.11 because its harder for the motor to turn the wheels with the 3.7. But on this occasion the ute gets up and goes before you realize you got to change gear. Back to how I know the clutch is slipping. The other night it was raining, I was sitting in third at time got to a slight incline up a hill nailed it seem to be fine and got out of it. Further up the rd I was in 5th droped it back to 4th and sitting around 2800 to 3000 and gave it gut. Full and heard the sorta trying to slip, revs go want to fly up to rev range, the thing is wasn't really moving any faster. I got out of it straight way, next second woof a big smell of clutch slip.

Its strange that its slipping, I've had one in my car now for years with over 400rwkws with no problems holding power even on a hub dyno where you can't hide clutch slip. Did you try talking to Mal?

Who installed the clutch? Were the installation instructions followed?

Simple things like putting grease on the input, or not using the supplied spigot bearing can cause this issue, and has happened before.

It looks like the clutch will need to be removed, and shipped back for inspection.
