.it could be clutch slip how old / many miles has it done and what power you running /torque

 

I've tried everything possible to get it to slip and it won't only when going hard through the gears spoke to our yard mechanic to day he said could be master sylinder not releasing fast enough when driving hard be checking it tomoro

 

are you using .4 or dot 5 fluid as might be worth a fluid change ? slave cylinder can be a problem with scoobs or try changing return spring on clutch fork first, hope this helps

 

Will be checking slave tomoro and checking service history when the fluid was changed last and what was used

 

Right, a bit left field here but does your boost solenoid need cleaning? When mine was clogged, I had what felt like slipping at wide open throttle in 4/5 gear. (I dont have a sixth gear, what a tightass!)

 

Boost is fine mate just checked service history can't see anything about fluid being changed I've had the car 2 hAlf years and I haven't changed it might need a flush and new fluid ???

 

Could be something as simple as that and if you do flush use .5 to replace hope this helps and worth doing anyway also good for brakes too
