Hey guys, sorry for the newbie type questions but I dont know much about 1st gens.

Can someone tell me if the clutch system on any of the first gens is mechanic or hydro.

I'm brainstorming up a rotary project and will be in need of a mechanical clutch. I'm hoping one of the 1st gens had one

Thanks,
STEPHEN

None are mechanical, all are hydraulic. You are not using the mazda xmission?

no, its actually not going to have a transmission. I'm brainstorming a one speed belt driven (similar to motorcycle) go cart. It'll be belt driven off the flywheel assembally directly to the axle. I just need a clutch so when I'm at idle the rotating flywheel wont keep turning the wheels.

I dont want to install all the hydrolic ****. Didnt they use to just make mechanical clutches that didnt have all that ****???

Not on the RX-7. It sounds like you need either a centrifical clutch or a fluid coupled clutch of the type you would find on a go-kart, but with a higher load capacity. Such a clutch would not have any external control (clutch pedal etc.) and simply be engaged by RPM. There are some race cars (F5000??) that use that arraingement, and what are/were the Malibu Gran Prix cars using (single rotor engines)??
