Lock Up Multi Stage Clutch

Managed to get a good deal on a MTC multi stage lock up clutch kit from a drag racer. The kit was fitted to a 620hp turbo hayabusa and used for full bore launches at 10,000 rpm. So should be more than capable to stop my clutch slipping with the higher power engine.

The clutch kit comes with a MTC billet inner hub that completely replaces the stock clutch centre and back torque limiter, a billet clutch basket, a modified clutch pressure plate, updated springs, and an updated clutch centre that has spring loaded arms that sequentially push the pressure plate down above 5,000 rpm and locking the clutch in place. There is also a larger billet clutch cover with a removable access lid for easy clutch adjustments. 

I decided to keep the Extreme Engines billet basket and to put the MTC item on eBay, which I'll list at a later date. In a drag application where the clutch is designed to slip before it locks, the racers often run more steel plates than fibre. For the time being I am going to run the standard clutch set up with the half plate at the back swapped for a full plate.
