Weighs approx. 8.84.bs. Effects of lightening rotating engine components: (0.5 x n2 x r2 + R2) / R2 n = total gear ratio (gear ratio x diff ratio) r = radius of gyration R = Radius of wheel/tyre This formula gives what accelerative weight the engine sees of the car per lb. Radius of gyration of a transverse engine's flywheel is approx. 3.75" So to determine "weight loss" for a flywheel weight of say 18 lb to 10 lb, the engine would see an overall weight loss of the car to accelerate in first gear of: 3.33 = 1st gear of 4 synchro 'S' box 3.44 = diff ratio (0.5 x (3.33 x 3.34)2 x 3.752 + 9.52) / 9.52 = (0.5 x 131.2 x 14.06 + 90.25) / 90.25 = 1012.59 / 90.25 = 11.22 lbs So for every 1 lb removed from the flywheel, the engine sees 11.22 lbs less to accelerate off of the total car. Therefore by lightening the flywheel by 8 lb, the engine sees a total reduction of the cars accelerative weight of 89.68 lb.

The Verto/Valeo type diaphragm included the pressure plate in its assembly, much like a 'normal' car set-up. The spring being of the 'finger' type as opposed to the disc spring used on earlier, three-piece assemblies. There were originally three diaphragm specifications using progressively stronger springs - small-bore, big-bore, and Metro Turbo.

If there's one subject that gets washed over when transplants or modifications are discussed its the flywheel and clutch assembly. There also seems to be a widely held belief that up-rating an engine from anything other than standard automatically requires a â€˜competition clutchâ€™. This, as with many other subjects concerning the Mini, is a myth.

There is only one version of this flywheel as standard, and fits all A+, Verto or Valeo (same type, different manufacturer) installations. And it’s heavy. Very heavy. Those up-rating power outputs in later Minis bearing this set-up were stuck with it. It is possible to shave a few ounces off this chunk of iron, but is difficult - especially for the DIY-er - and not cost effective when paying to have it done.
