Post by: gtatbrissy on September 17, 2009, 07:12:32 AM: yer i agree with fiftytakedowns u will have way to much clutch travel lol

Title: Lightweight Flywheel
Post by: fabe on September 17, 2009, 09:26:12 AM: That looks like a lightened stock single mass flywheel...
How much does that weigh??
Stock is about 10kg... I've machined mine down to 7.6kg... Yours looks like it has more metal removed...

Post by: DaveM-sport on September 20, 2009, 01:24:19 PM: I used a lightened M20 flywheel with 325i clutch and starter.

Flywheel after machining and balancing weighed 5.9kg so with the stronger clutch a saving of about 4K over the standard flywheel and clutch.

Post by: fiftytakedowns on September 20, 2009, 01:42:44 PM: someone bought be an m42 clutch kit brand new, but I want to go for a Lightweight flywheel. Where can I find some cheaper aluminum flywheels for the stock dual mass setup?

(sorry for hijack)

Title: Lightweight Flywheel
Post by: gtatbrissy on October 08, 2009, 04:56:54 AM: I have now finished my conversion... epic lol
pros - better throttle response, revs harder from 5k+
cons - idles a bit lumpy, doesnt like revs below 2k although this may be a good thing ;)
highly recomend it
Title: Lightweight Flywheel
Post by: fiftytakedowns on October 08, 2009, 10:42:59 PM: Does the car feel like it has more torque, people say it revs more freely, but that doesnt really make much sense to me?
Title: Lightweight Flywheel
Post by: gtatbrissy on October 09, 2009, 01:47:13 AM: low down u dont feel that much difference but once u are in the power band the car pulls alot stronger if that makes sense...

@ fiftytakedowns & gtatbrissy, that is a single mass flywheel which has a completely different clutch and pressure plate than the dual mass, i have one on one of my cars

John

It was machined by a very experienced local machinist and was balanced by a company in the UK who build Audi DTM, Honda BTCC and VW F3 engines neither of which would have produced or worked on it if it was un-safe.

Post by: Boyracer on November 03, 2009, 01:01:54 PM: As long as the stuff is only removed from outer edge of flywheel and it is balanced properly, lightened flywheel is actually safer than stock flywheel.

Because lightened flywheel has less mass in edges, the center (which is the area that fails) will have to endure less stresses because there is less centrifugal forces tearing it apart. Also, lightened flywheel stores less energy due lower mass and it does less damage in event the flywheel breaks.

Because my project will rev to around 8500 and stresses are quite high, I decided to get custom billet steel flywheel since the price is going to be reasonable.

Theses parts are going to form the clutch:

That Tilton pressure plate will be converted to operate single sintered three paddle disc :)

Post by: gearheadE30 on November 05, 2009, 12:45:29 PM: wow.... that's pretty impressive. I think its about time for me to lose the dual mass haha
Title: Lightweight Flywheel
Post by: fiftytakedowns on November 05, 2009, 09:04:02 PM: Maybe we should do a group buy on the AAsco lightweight flywheels
its like 420 at Horsepower Freaks
400 at some other sort of shady business. I think horsepower freaks WILL price match.
