Running a corsa with a LET in it. Was driving fine, superbly in fact. Took it out the other day and it still ran ok, till about 4000rpm. The turbo carrys on spinning and the engin note gets louder and louder and it carrys on revving as normal, but the car doesn't go any faster. It just continues at the same pace even though the engines still revving ok. I think its got the lighter XE flywheel and the LET clutch (don't quote me on that though).
Eating a driveshaft spline (but then surly it wouldn't go well at all or move anywhere?)
Eaten a clutch up (clutch not being able to handle the power as from 4k yupwards (could be an XE flywheel/clutch mated in a 2wd F28 gearbox, its not my car so im not sure) so its just spinning).
Eaten a diff up in the gearbox (but again if it had wouldn't it not move at all?)
Air flow meter?
Has anyone got any ideas, need toget this sorted by thursday.
