upgrading flywheel

[Cubes]

So what about the Kevlar clutches then..

I remember GTRBen used to use one in his GTR and he swore by them.

i got one of those extreme clutches too. Really happy with it. Got the lot fitted for $880 some time ago... i think it can handle 450hp at the engine? not sure, but whatsisname has 250+rwkw and has just fitted one of these, i think hes pretty happy with it.

dunno bout kevlar though...

what lighthened flywheel can u use with that clutch? whats the bolt pattern?

[skyzerr33]

i have the Ogura lightened flywheel

all 4.8 kgs of goodness

its took 1/2 a sec off Rev210's 1/4 mile time alone.

as joel said the off boost acceleration just doesn't compare this thing rocks.

mine was $720 landed at my door from Taka

does the Ogura flywheel bolt directly upto any clutch? what stud pattern does it use?

[JNR24]

Of coruse it will dude!

If you buy a RB25 Clutch its going to boltup to any RB25 Flywheel. (there 5 bolt by the way)

and likeways the other way around.

cheers trev!

bolts up the same as the stock flywheel

i'll find the pics and post em (just out of the box when it arrived)

front

[Cubes]

wow.. Thats way different to mine.

[skyzerr33]

back okay from the shadows u can make out how deep the walls of it are.

on the stock flywheel that whole area is solid metal, to make an analogy imagine the pic as an empty cake tin (the ogura flywheel) the stock flywheel whould be the cake tin full.

[skyzerr33]

different engines joel is all i can say

[Cubes]

Mine definately looks smaller though.

joel your looks heavier than the r33 one

It doesn't actually matter how light a flywheel is but where the material has been removed.

However a certian extent measuring the weight is a good indication.

Around the outside is where it affects inertia.

You could have 10kgs 5cm's away from the crank and it would rev quicker than if you had 5ks 15cm's away from the crank.

Its not so common with 6cycl's but with 4cycl's you will find if you remove to much material from the center of the flywheel you will get vibrations, nasty ones.

Still I can't complain for a Chrome Molly Flywheel for an extra $200 when fitting the clutch.

The rev's do drop really quickly now when free reving and is heaps quicker in matching rev's when pulling up hard.
