MINI COOPER FLYWHEEL ULTRA LIGHT 8.5LB COMPETITION

Ultra light (8.5lbs, including the box!) steel race flywheel for non-Verto clutch with ring gear for non-pre-engaged starter.
The latest refinement of the Ultra-light Mini flywheel is now made symmetrically to reduce harmonics vibrations caused by earlier versions - yet it still weighs just over 8 lbs.! This is considerably lighter than a safely lightened standard iron flywheel, and also provides a much hardier clutch surface..

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.
A set of three spacers are supplied with the flywheel used to maintain the correct postion of the straps. They are .425" thick, .620"OD and .380" ID
