FLYWHEEL STEEL ROAD/RALLY INERTIA STARTER C-AEG421 - FLYWHEEL STEEL ROAD/RALLY INERTIA STARTER Light Weight STEEL flywheel! For non-Verto clutch and non-pre-engaged starter. se C-AEG420 for pre-engaged starter type "1lb off the flywheel is like taking 100 lbs off the car!" Not quite rational but close. This rule of thumb indicates the importance of flywheel performance. The stock cast iron 1275 flywheel is almost 22 lbs. Even the "S flywheel weighs almost 17lbs. The stock flywheel is "cast" iron and thus not very safe to lighten! This new "Street" Steel one piece flywheel is 11 lbs. and provides tremendous improvement in acceration! (The full race version C-AEG619 is 8lbs.) Special Tuning originally produced this flywheel and it was even fitted to Allegros by Leyland to stop clutch judder under warranty claims 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. …more
FLYWHEEL ULTRALIGHT STEEL 3.8KG INERTIA STARTER C-AEG619 - FLYWHEEL ULTRALIGHT STEEL 3.8KG INERTIA STARTER Ultra light (8.38lbs) forged EN8steel race flywheel for non-Verto clutch with ring gear for non-pre-engaged starter.Forged is more rigid at high speed. The latest refinement of the Ultra-light Mini flywheel is now made symmetrically to reduce harmonics vibrations caused by earlier versions (those with just 3 large lighteneing slots)- 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.. Not recommended for road use. (See C-AEG421 FOR FAST ROAD) 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.

FLYWHEEL VERTO LIGHTWEIGHT WHICH ALSO UPGRADES CLUTCH ALSO C-AEG422 - FLYWHEEL VERTO LIGHTWEIGHT WHICH ALSO UPGRADES CLUTCH ALSO For pre injection Verto clutch cars, it is also designed to increase clamping pressure which affectively upgrades the actual performance of the verto clutch, which with the AP pressure GCC679 (part of GCK151AF) exceeds all previous high clamping pressure plates including the turbo. Light steel outer section for Verto type assembly which Weighs approx 8.84.bs.

Therefore by lightening the flywheel by 8 lb, the engine sees a total reduction of the cars accelerative weight of 89.68 lb. On the flywheel, check the pedestals which the pressure plate bolts onto in case it has sharp edges, which can interfere with the springs on the pressure plate preventing it from moving (clamping it) This flywheel is designed to be fitted with a Valeo pressure plate. If an AP type pressure plate is to used, it may be necessary to relieve the two holes on the pressure plate used for the location onto the flywheel. …more
