FS-996 GT3R clutch/flywheel (usable on G50's)

[JoeMag]

996 GT3R 7.25" Clutch, floater discs, friction discs and flywheel with ring gear.

Clutch is Tilton 66-012-HORA. Friction discs new are 0.104" thick, ones included with this package are ~0.101" - ~0.102", and instructions indicate first 0.002" wear happens pretty quick. Wear limit is 0.094".

Clutch with friction discs run $700 new... Similar type flywheels run in the $900 range...

Can be used with standard G50 transmission and 911 9 bolt crank. Will require circular throw-out bearing. Flywheel spins up balanced and is not warped.

$780 shipped CONUS (price updated due to addition of parts below).

...here's a few more bits to add to this setup. Spare clutch with discs (~0.100" thick, discs not in this pic) and the botton part of throw out bearing (you'll need to get piston)

How much does that assembly weigh?

Thanks,

It weighs about 17 lbs... However, over-all weight definately doesn't tell the whole story on this due to moving rotating mass in. Here's copy of post I put on another forum regarding this...

~~~~~~~~~

I think bene's are combo of clutch wt red'n and moving the mass toward the center. I've been told that reducing the moment of interia (moi) on a flywheel/clutch that's ~200 lb-in^2 by ~25% yields about 4 rwhp gain (I believe 200 is rough MOI of this flywheel/clutch).

Just looked up the moi for a disc and it's 0.5mr^2 (m=mass, r=radius). this clutch/disks weighs ~8# and i looked up weight of light wt clutch/disk on pelican and total weight looks to be ~13lbs. therefor roughly moi lt wt clutch = 0.5 * 13lbs * (9.5"/2)^2 = 146 and tilton 7.25" = 0.5 * 8 lbs * (8"/2)^2 = 64. Obviously these MOI's are not right due to the gross assumption, but MOI is roughly half.
