I don't think I would install a lightened flywheel with out doing the entire rotating mass balance. I think all should include crank,piston,pins, fan; ect... If your gonna use this on a DD I wouldn't go less than about 15 lbs. Whats the real benifit on running a lighten FW. I would think the quick revs only. Whats the down side? Float the valves on a missed shift. What about the loss of TQ and driveabilty. Just my 02 cent, but I like it when we go outside the box. Thats why I hang out around here!!!
You guys will never stop letting me learn- Thanks for that......

I machined mine back in the day down to 11 lbs and ran it on a daily basis with a Six puck solid hub disk. Made a grabby as hell clutch but if you learned to drive it and slip the clutch just a little it wasn't that big of a deal.

The one I made, I machined the normal wieght off the backside and then layed it face down on the bed of a mill. Then came in and carefully milled all of the area on either side of the dowel pins. I did this on four sides. All done without a rotary table. It was ugly but it worked well. Never had a problem.

Joe Ricard has it now. I think he was little ill that it was as ugly as it was, but it worked great.

You should be able to get it down to around 8lbs without too much work.

Could it be possible to machine a 911 (225 mm) clutch & pressure plate to fit a 914 flywheel? For high HP engines.

I lightened my first VW flywheel on a disc brake lathe (IMG:style_emoticons/default/biggrin.gif) . Damn......that was a LONG time ago (68). Balancing? Hey, as an edumacated teenager, if you took the same amount off all the way around.....it's STILL balanced, right?? (IMG:style_emoticons/default/biggrin.gif) I put that puppy in a 58 Rag with a 63 40 horser. Hang on brother! Oh yea.....I agree with you Mikey, they are sexy (IMG:style_emoticons/default/thumb3d.gif) . Sorry I missed ya last week Mikey...................Dad (IMG:style_emoticons/default/driving.gif)

I just ran a newer program on the cnc today... came out at 12lbs. Yes I can get it lighter if you want. Looks like we will be charging 150 to lighten it, and 60 for the surface. Also if youre intrested found the parts to modify the flywheel to take a double clutch pack(pricey though).

I am looking to get extra flywheels(those of you who offered) so I can get them ready to trade out for ppl who want a fast turn around.
