I decided to upgrade my flywheel adaptor.

The old one just sandwiches in-between the Mazda CW and the Porsche flywheel. It works, but the "new model" is in a whole different league.

I turned out the new adaptor out of 1045 steel. I made it so the adaptor bolts directly to the CW and the flywheel bolts to the adaptor.

I should be able to dump the clutch at 10 000 RPMS now.

^^^^^ I turned down a bushing so I could drill the holes in the adaptor accurately

^^^^^^ this is the bushing.

^^^^^ I used the bushing to drill the adaptor.

Here's a time lapse I made that goes over making the adaptor out of a chunk of round stock.
