Post subject:  Steel Flywheel Update.
I have been reading throw the search results on here and there doesn't seem to be a clean answer. :? I was about to buy a Swiftune Feather Light Flywheel and Backplate but now the AUD has gone so bad I don’t think I can justify the $874 + post.

So what are the current 'good' ones to get? Are the new ultralight ones any good?

It will most likely go in a 1293 with a Eaton supercharger, for manly track work. :wink:

Thanx Nathan

we use the ulf and light backing ring and it does make a diiference

the only problem so far was one of the welds split so we welded it again and added 3 new welds

Have a read of Des Hammill's chapter on flywheels in his revamped book on tuning 1275 A series. There's some interesting info on the pros and cons of steel versus cast fywheels.

Ok well it’s been some time but I finally order a steal flywheel assembly. Ended up with getting one from MED engineering in England very nice to deal with and took less than a week to get here and no import duty :wink: When i spoke to Swiftune we agreed that there Feather Light Flywheel would have been to light for my application. (1kg lighter agen) Also got a AP Bonded clutch plate and a Grey dot diaphram.

According to the bathroom scales:
MED flywheel: 3.9kg
MED back plate: 1.4kg
MED clutch package: 6.9kg
STD one peace flywheel: 7.3kg
STD cooper S backing plate: 2.3kg
STD clutch package: 10.9kg
So the MED item is about 4kg lighter then STD item, should make the new motor a bit livelier :lol:

Yes the Flywheel Shield is going to be on the list of addition for this build I think.

When I get all my stuff back from getting machined next week I will post up the new build the flywheel is going in to. Quick hint it’s a fully worked 998: 100” over, wedged, bladed and nitrated crank, lightened rods, centre main strap, the big 12940 head with it converted to 11 stud, new blower with 15 ish psi of boost and a few more goody’s. So I think it will rev well. :lol:
