Light weight flywheels

[B-ran]

So my brother, who had an 06 Cayman S, had his pressure plate commit suicide. So he decided while he was in there to also replace his flywheel with a light weight one. He called me yesterday to rave about how amazing it was. He said it feels like a new car with more low end torque feeling and a super responsive throttle.

Now I’ve read elsewhere by the internet lords of doom that putting a light weight flywheel in our damnable 996s will grenade the engine. I’ve also heard that Sharkwerks won’t build a car up without one, at least in all his personal cars.

What are your thoughts oh gurus of the 996 interwebs?

From what I have read, the light weight flywheels cause abbie normal vibrations on the crankshaft, thus expediting demise of the crankshaft and all internal engine components when it implodes. The dual mass flywheel dampens vibration, thereby saving the engine from internal destruction. Porsche engineers...pooh. What do they know about flywheels and such? But, each to his own. Whatever trips your trigger.....

I don't know about y''ll, but I'm sticking with Porsche on this one... flywheels are dangerous when they malfunction.

wow, there's a whole genre of wheels flying off on youtube.

No joke my friend! Check this one out!

B3, respectfully I have to ask, why do you post videos of flying wheels that are so obviously dual mass flying wheels and not light weight single mass flying wheels? Ugh, the internet scare mongers never sleep

I’ve read that the single mass flywheels effectively eliminate the “harmonic dampening”, which sounds like some guy putting sound deadening material around his teenagers bedroom so he doesn’t have to listen to the loud rap and devil worship music. But the one solid example I could find out there was Jake Raby posting something about a car where he thought the lw flywheel destroyed the crank. Now this car also had twelve thousand track miles on it. Sooo if a car can survive twelve thousand track miles with a light weight flywheel, just how darn bad is it? Of course the guy who’s engine went kaboom probably could tell me how bad it is.

I can only add that when FSI was building my 4.0 they would not install LWFW......they recommended against it.

ha! Don't know if they're truely dual or single mass, but they're definitely NOT lightweight. Did you see that one clip where it flattened that asian dude? Ouch! That's gonna leave a mark! Now, I'm going to have nightmares and start scanning all the highways when driving.

B3: One question and one comment:

Was the white Jeep ElSchnell's?

Don't stop on the side of a busy road to take a pee over the guard rail.
