ok im changeing my clutch and would like to no whats best t do


i want to do as much as i can with out going OTT whilest the box it out,

so i was tnking of getting a lightend fly wheel

now is it true that if i wanted a lightend and balenced one i would have to remove my crank to get it set up right??

if so sod that.

if thats the case what up grade fly wheel do you advise, and whats the benifets of getting a lighter one,
aprt fromt he engine can turn over easyer..

will it alow it to rev higher? or pick up faster?

do you recomend doing this and getting one?

thank you

A lightened flywheel won't make you rev higher, it'll make you rev faster. Will increase acceleration a good bit...

Only drawback is that idle becomes somewhat lumpy!

[siggy]

Idle only becomes lumpy with Hi lift or scatter cams.

The increase in acceleration is noticable, but not fantastic

You should really have the flywheel balanced with the rest of the engine.

Sorry wrong choice of words. Not necessarily lumpy idle but basically the car will be more prone to stalling...

prone to stalling... !!


is it worth replaceing it then?

You won't have any issues with a road spec lightened flywheel, and you will notice the extra acceleration and faster starting. You'd only really notice the problems with lightened flywheels if you were shaving off insane competition amounts of metal from it, but that's why they make road spec and race spec wheels. The standard item can easily afford to loose a few pounds with no ill effects.
The benefit is that each pound lost from the flywheel effectively removes about 80 pounds from the load on the engine when it accelerates the car (in first gear, it's all due to the gearing which is why you don't see any more performance at the top end of fourth gear). The actual saving in your case depends on your wheels, gearbox, final drive and stuff but that's a good rule of thumb.

just had mine and maxmax's lightened. They are verto flywheels so theres not as much to take off as on a pre-verto but it should still b noticable!
