Aasco flywheel is here.

I would love that. JK They seem to work great on peoples track cars. I had light weight flywheels on 3 other cars and never had such a issue. One of the cars had over 90k on that setup.

It depends on the engine manufacturer.
Some companies fully balance the crankshaft, and the only thing that the flywheel does is provide needed inertia.

Other companies rely on the flywheel to provide the balancing forces for the crankshaft, along with the needed inertia to keep things spinning.

I could almost guarantee that your other engines were all internally balanced crankshafts, and that's why you didn't have any issues using a lighter flywheel.

Maybe your company took the balancing needs of the Porsche engine into consideration.
I don't know, so we will have to wait and see what Jake has to offer.

But yes, its kind of need having an actual sealed bearing as the pilot bearing.
Still doesn't make it much easier to replace if it goes bad, though.

BC.

ok. I see where this may go. I just read an article that Jake posted back in 08. The article was about a track car with 12k track miles. That is a lot of miles for any car on a track. In my opinion. I know nothing about how often track cars are rebuilt or whatnot. I hope your article is going to be good news for me not keep buying junk porsche flywheels.

Not sure I get why the Porsche flywheels are junk. There are several folks with more than 150k miles on their cars on PPBB, one even with 218k+ miles on his 2.7L boxster, still on his original clutch and flywheel. It may not look as nice or is crafted as well as the LWFW, but it seems to last. I'm at 59k on my original clutch and flywheel, and so far no issues at all. Could your issue be due to something else affecting your flywheel life?
