Re: Lightweight Flywheel
Fuel economy should improve as the rotating mass of the engine is reduced, but as most likely the people doing this are going to be redlining it in each gear then fuel economy is probably not what they are worring about.
Lightweight alloys are an easier way to reduce ratating mass.
My old wheels were Alfa 5 hole 16 inch by 6.5 jobbies that came with the old Sports pack 1 - they weighed 9.25KG each.
My new Team Dynamic Pro Race 1 wheels are 17 inch by 7 and only weigh 7.5KG each.
Even though I've only saved 7KG in total car weight, the fact that this weight loss is on the wheels It counts as alot more (Someone somewhere said you can multiple the weightloss by a factor of ten when doing say 70mph).
So even though the lightweight flywheel is (at a guess) say 1KG lighter, it makes a noticeable difference because it is spinning so fast.
I read on a Mitsubushi EVO forum that you can get titanium wheel bolts which save about 1KG in weight which isn't much, but counts as more because it is rotating
