Longer rods lose less energy into the bore through vector forces.
Lighter flywheels use less energy to accelerate them and also slow down
quicker when you take your foot of. This is good on a performance vehicle.
Lighter is better.
A stock :20B wheel is 13kg and most race cars are running 4 -5 kg wheels. I
have an OS Giken chrome moly wheel coming that weighs in around 2 kg
including ring gear
When you add the clutch weight to the flywheel the lower the total mass the
better. This is why people use small diameter (5 1/4" 133.5mm) twin plate
clutches in race cars. With the smaller diameter the polar inertia is
reduced.
CR = close ratios
Lower ratio diffs have smaller pinion gears and are not as strong as diffs
with larger pinions.

I heard 1:1 is best for power, what do you mean by "or better"
> heaps of compression
> forged pistons
> aluminium flywheel
I have a 6cylinder clutch and flywheel sitting on my garage floor which is
1kg lighter I think. Is there a limit to how light you should make a
flywheel?
> CR gearbox and of course
What is this?
> 5.1:1 diff
Do lower ratios break easier?
