Audi single mass flywheel... which one is this?

It has 8 bolts, 32v v8s have 10 bolts

I realise that it's an 8 bolt so is either V6 or V8 (40v) or maybe even 5 cylinder but I was wondering more about the manufacturer and particular applications due to it's depth etc.

Have you weighed it? I know my 7a came in around 29.3lbs on the house scale. I don't think it's a 7a maybe it's something diesel idk but weight might be a good starting point.

TDi's have the 60-2 tooth setup?

No, they use a crank sensor, and they're all dual mass anyway.

The design, shape of the 60-2 teeth, and presumably lack of any Audi markings or part number suggest aftermarket to me. Most likely B5 S4 / RS4 I reckon.

The wear pattern looks like it was running a 228mm clutch rather than a 240, which is a bit odd.

Also will it fit a V8? I5 flywheels won't, V6 ones will.

Ok that makes sense.

I'm using a stock RS4 V6 flywheel (dual mass) for my other S8 engine conversion and that bolts on without problems.

This flywheel is fairly shallow in comparison to the dual mass... I'd love to find out who made it so I can see the spec.

It had a 4 puck racing clutch on which I think is 240mm. The flywheel has obviously be allowed to get rusty and then cleaned up.

Oh, I've just weighed it and it's 21 lbs.
