Any feedback on the positives & negatives on having a lightened flywheel fitted to our mini's could you post here please.....
Positive is the motor will rev quicker. Great for racing!

Negative is you'll have to rev it higher to take off from a start because the motor won't have the weight of the flywheel spinning to help it.

"Negative is you'll have to rev it higher to take off from a start because the motor won't have the weight of the flywheel spinning to help it."

hmm havent done any change in take offs.. still doing it at 2k.

But then again i went to lighter Weight wheel and tire combo. Which countered the effect of having a lighter flywheel. This is VS stock.

Stock: 28 lbs flywheel with 116 lbs worth of Rims and tyres
MOD: 11 lbs flywheel with 64 lbs worth of Rims and tyres

A flywheel that's significantly lighter than stock will render the car difficult to drive in normal traffic situations, as indicated above.

Maybe you can find info or posts about folks who've installed one, or had their stock flywheel lightened. I've never seen this posted, but I'll bet it's somewhere.

Please let us know what you do, very interesting.

Good luck!

Has anyone got first hand experience of a Fidanza flywheel in a MCS?
Is the chatter at idle a major issue? I've heard that a lightened crank pulley sorts out those harmonic issues anyway...

I am planning to do a full drivetrain upgrade in the new year (clutch/flywheel/quaife).


One last thing, does anyone know if a Quaife diff messes with the working of ASC traction control??

Cheers,

Henry

I havnt got any experience in a lighter flywheel but do remember reading somewhere on this site that someone regrets doing it because of how loud his car is now at idle. I also remember reading that the MCS doesnt get much advantage out of a lighter flywheel compared to other cars, cant remember why though. I bet that was helpful :rolleyes:

I posted this before but now I cannot find it.
I have an aluminum flywheel and a competition clutch on PKT RKT.
The clutch (due to its monster spring rate) is a bit of a pain in traffic, nothing to do with the flywheel.
I have not detected ANY difference in the idling characteristics.
As I did not do back to back comparison with and without, can't speak to an improvement in "speed" due solely to the flywheel.
Hope this helps......

Perhaps this will help make up your mind.....if you're gonna fit it yourself.....it is a major pain in the rear end.....AND you will need a pal.....even the factory manual calls for two men......if you're gonna have it done....like NIKE says....Just Do It.....

Thanks Roland, hope everything go's well, just one point though, someone had posted somewhere that reducing the weight of both flywheel and pulley causes major problems with the crank not to sure what though perhaps you could enlighten us...

Rasp Yes I had seen that too. It maybe an assumpsion rather than an experience.
The only way to know for sure is to test it . I shall grasp the nettle!

Thats what I like to see , someone getting in there and taking the bull by the horns and all that malarky, I done the same thing when I got the Hartge conversion and you know I have never looked back but there is always room for improvement dont you think?, be interesting to see what you come up with Roland...

Good Luck...

On another car, I went from a 22 lb to an 11 lb flywheel. There were no problems with launching, noise, chatter, or any other driveability issues. It didn’t take any time getting used to it either. The car was noticeable quicker on the launch and quicker to slow when lifting off the throttle. BMW could have used one in the first place but unit cost is always a concern. Get a two piece so it can be resurfaced when needed.

round CC than me.! It arrives tomorrow ( plus flywheel ) will fit it xmas day at lunchtime
Regards Roland Gt Tuning.
Doh!

It all depends on the driver though ;) :p :D

Seriously, let me know how you get on and please report how it affects driveability, ASC and if it pulls the car all over the road (!)

Have a great Christmas,

Henry
