When pushing more HP - impact on drivetrain?

I'm super confused here and also extremely interested. Our flywheels are dual mass, the clutch disk is single mass.

Do you have the PN for the clutch you're talking about? I would love to see it.

Already tossed everything; so no pics..

The Audi clutch gripping surface has a smaller ID; but the same OD. The dual mass clutch has workings and weird stuff happening on the inside of the clutch so the ID is greater and the OD is the same. IDK what the weird duel mass trickery was; didn't take a hard look at it just went strait to the scrap yard. The dual mass clutch's band was about 3cm thick; I'd say the Audi disk is about 4 or 4.5 cm thick.


EDIT:


Damn I was close guessing their thickness... This guy is selling A4 clutches and has a side by side picture.

That's really interesting. The only time I've heard of using a sprung clutch disk on these cars was with a single mass lightweight flywheel. This wasn't a popular update for many because that DMF serves as the engines harmonic balancer and deleting it may or may not cause crankshaft failure.

What'd you say killed your original m96 motor?

IDK about killing your crank... Honestly if I was developing a car and the crankshaft was so fragile that it requires a special flywheel I wouldn't use that crankshaft. IMPO the M96 is a TERRIBLE engine, but thats just me


Don't know and kinda don't care about the original engine from my car; I don't hold the M96 engine in high regards LOL
I was told by the PO it was IMS failure, but the guy I bought the car from ate meth for breakfast like every day for 10 years. He saw the cash in my hand and got a big woody for that next crack rock. LOL


All my trash talking aside; my wife had an M96 powered boxster for a couple of years. No IMS, D chunking cylinders, no cracked cylinder walls, or cracked heads so IDK.
