Flywheel

[Brett240]

just found out why my engine was making an incredibly bad noise yesterday, it wasnt what i thought it was (stuffed bottom end bearing ), the flywheel was coming loose at a rapid rate!

so heres my question, does anyone have a really light flyweel attached to their car? what are the driving characteristics? will it drop its revs to quickly during up changes? stall easily?

but from what i have heard, you have to learn to drive all over again.

the characteristics are totally different and you will rev faster and they will drop off just as fast.

figuring, the stock flywheel and clutch assembly is about 42 lbs and you drop about 15lbs off of that well there you have it.

im not sure of the weight exactly of the flywheel itself, but i know with pressure plate, clutch and flywheel the total is 42 lbs. ive shipped that.

i would say at least 24 of it is the flywheel. its just something to get used to again.

If you like sporty cars, and I think you do, you will enjoy the improved throttle response. My 240 employs a 13.5 lbs aluminum flywheel with a Centerforce II clutch and I love it. It drives better than it ever did with a heavy stock setup. Would I ever go back to a stock flywheel? I think not!!!

what are the con's?

Go for a lightened flywheel - best change I've made on any car to improve acceleration

While you are in there you might as well have a look at the clutch plate and renew the rear oil seal around the crank:classic:

You would not want to do it all again later

i already have taken a little out of the original flywheel already, but i might take out a bit more. i'll leave the rear main seal, its only 400 miles old. how much can you safely take off the stock flywheel?

How much does a lightened flywheel go for?

[Brett240]

dunno bout bying one but i had mine 'street' lightened and balanced with the clutch and pressure plate for AUD 120

What was original weight Brett and how much did they take off? I gather from your previous post you want more taken off. Could you not notice the difference?

[Brett240]

i can only guess at the weight george, but if the flywheel weighs 13.5KG and im pretty sure thats close they have removed about 2KG. it did make a noticable difference, the car was happier to rev and the throttle responce was definatly stronger.

as the flywheel is out of the car at the moment i figure if it wont make the car difficult to drive id like to take out a little more.
