3.9 g6 GXP flywheel

[NateD4]

I suspect the 3.6L use a totally different flywheel and probably even bolt pattern on the crankshaft.

The harmonics of the 3.6 an the 3.9 could be totally different as well, which, is especially critical if they use a dual mass flywheel.

Sorry Joseph you lost me....

There are really only two factors that play into torque the flywheel sees. 1) Available traction and 2) Inertia loading of the flywheel at RPM. No matter how you slice it though the available torque at any given time is the function of: HP = RPM * Torque/5252. Solve it however you want. The max engine out put is the max engine output. Regardless of whether the car is moving or not.

In any rate I prefer not having failures of the flywheel. Hopefully I'll have a few made in the next month or so.

I agree, but my concern involves the transmission shock loads not flywheel failure, as it relates to instantaneous load. From a mechanical standpoint devices tend to endure exceeding load capacities better with a gradual onset better than instant, stacking 500 lbs on a 475 lb capacity board in four increments vs all at once. There's more science above my level of knowledge regarding the theory but I believe most tranny/drivetrain failures behind the same engine at the track usually occur at the starting line as opposed to mid track and I suppose the missing recipe would be the exposure time to the high load and at what point it's greatest. Clutch dumping with stock motors can break trannies for more relevance to the shock load subject.

I just don't see the need for such a scientific approach to a dualmass flywheel on motors that have performed dependably for decades with a solid unit except for the chatter that results in a 6 speed unit without it, including in the Corvettes.

Does the 3.6 in the new Camaros use a Dual mass flywheel? Can it be used behind a 3900?

The proper manual flywheel for the 3.6 can be found in the Cadillac CTS and the appropriate Saab cars with the same engine platform. The first itteration of this motor occured in the Caddi years ago when the CTS was first introduced if I recall correctly, however it was a different displacement.
