As a rough guide....

Depends where the weight is from relative to the crank centre line, the gearing, the weight removed and the weight of the car

The weight from any internal lightening is approx 1:10 in 1st gear

So 1kg off engine internals is approx 10 kg off the car as you go through each gear the 1:10 reduces

There is a formula in DV's book

It has no affect on top speed, but you will get there quicker....

Megalite Fw, alloy spacers, 3 straps, En24 lightened bolts, Alloy Back Plate Ti bolts. Whole set up 4.8 kg

..it's hardly a flywheel - more like a pressure plate with ring gear attached!!

Cant blame anyone looking out the window in physics class, loads of bad physics teachers around, while it is the most beautiful class possible if done right :)

Vizard yellow book page 382, 3rd edition - what is there really sounds logical and proven practically and with formula.....guess no really doubt regarding benefits of lighter components,  just find the right proportion of components for intended use.
