.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 lightening slots)- yet it still weighs under 4kg.! 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)
EN24 has better wear and shock resistance than EN8 which can fret on the crankshaft of highly tuned race engines. EN24 is more stable as it is a high strength alloy steel(nickel chromium molybdenum).
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.
