Anthony,
A flywheel is just a device for storing and releasing energy from the
engine.
With a heavy flywheel, as an engine is accelerated, the amount of energy
stored in the flywheel increases in direct proportion to the rotational
speed. This takes energy from the engine that would normally be directed
further down the drive train to the driving wheels.
On a hill, when the engine is unable to produce enough torque to maintain
the velocity in a given gear, energy is released from the flywheel to
supplement the engine torque output. This means an engine with a heavy
flywheel loses less speed on the hill than the vehicle with a light
flywheel, provided the same gear is used.
On a flat road when two vehicles identical in all respect apart from
flywheel mass are accelerated, the vehicle with less flywheel mass will
always accelerate (and slow down during braking) faster than a car with a
heavy flywheel.
For a cruiser use a heavy flywheel. For a racer/sporty use the lightest
practical rotational inertia combination, as this will give you the best
performance.
Any comments from the engineering fraternity?
Cheers
Feral Errol

I'm not sure that this information is correct but since your application is
for 'rally' then the alloy flywheel might not give good acceleration/torque?
when going uphill.
Can anyone confirm this? All I am going of is the part descrition in Gran
Turismo hehe anyway there might be some truth in it.

I am going to buy one from Errol, He's an engine
biulder whos giving me a hand and one of rhte
questions that hes asked was how much was my flywheel.
BUT I am still not sure if I should go the alloy
flywhel option yet, being a rally car and all.?!?
Hence thats why I have not ordered it yet!?!?
Cheers NAt
