lightened fly wheels

[Powered by Spearco]

I've got a 210mm lightened flywheel with a 200mm Bug solid disk. No issues with shifting or power loss. Also I can ease out the clutch at idle and will not stall out.
Yes it does rev faster and return to idle faster.

Just did this about a month ago, car is a '92 four door Jetta with an AAZ. Cut the flywheel from about 14 pounds to about 10. Stopped there because of balance cuts that were in the outer ring, left them alone. Would I do it again? Yes, in a heartbeat. Pretty sure the car is more responsive, just feels like everything is a little looser, runs free compared to before. Torque and horsepower haven't changed, just momentum in the flywheel. Did stall it twice the first day I drove it , but it didn't take long getting used to the the change and haven't noticed it since. Next one I have apart will get cut farther!

You have a solid disc? I'm interested in running one but concerned on street use. You say the word i'll get one. Its my daily driver. Also you used a bug disc?

My lightened 190mm flywheel, presure plate and disk weigh maybe 14 to 15 lbs total.  Using a solid kennedy 4 puck disk.  For street driving, I would not do the solid puck disk.  I autocross this car.  recipricating parts in engine are balanced within a couple grams.  The motor quits pulling hard around 5700 RPM.  Yes, Giles did my pump.  It does rev VERY fast, but it is a complete package, not just the light flywheel.

For street I would lighten a 210 and use a regular spring center disk if I went with a lightened setup. The 4 puke solid can get anoying in stop-n-go rush hour traffic.  I've been thinking of switching to my lightened 210/spring center disk to see if it will help on pro-solo drag race starts.  The solid disk is not a problem with regular autocross since time doesn't start until several feet after you launch.

A good machine shop is worth their weight in gold.  They have the tools and know how to do it right the first time. Just like Giles does with the pumps.

hope the info helps.

I too daily drive my truck in stop and go trafic. Still with the setup I run, no slipage, no chattering, no stalling.
The complete engine and clutch, rotating assembly all balanced and lightened.
I guess I could of used the 190mm flywheel but I'm not planing to use it long in there, so I used it for now.
Yes a Sachs, Bug solid clutch disk with a 16v pressure plate.
Works great for me.
I running a 1.6 MF bottom end with the AAZ ported and polished head. Stock manifolds and down pipe.
I guess I've got some power to put to the clutch set for now  .

I've got about the same setup as your engine. If it doesn't chatter and isn't an on off switch. Is the bug disc a puck style? What material is it? I like a firm clutch engagement but it needs to be able to slip a little on take off.

The Bug disk is an organic full surfaced dish with a solid hub.
It'll slip if ya let it, kinda hard to do, but I know it hold good though when I want it to.
