I'm soon to be pulling the tranny off of the motor to install a new final drive. I was planning on having a few pounds shaved off my R flywheel rather than buying a new flywheel. I have heard that you can only remove 5lbs off of a stock flywheel. Since the ITR flywheel is 3lbs lighter, does that mean that I can only have 2lbs safely removed, or is the R fw its own seperate casting? If I could take 5lbs off of the ITR fw that would be nice.

Any help or input is appreciated, and yes I did search first.

 

I took a few lbs off my old FW , it wasent worth it at all IMHO.

its not so much how much weight but more of where the weight is located , the upgrade to a nicely designed lighter FW was one of the better things I've done to the car.

that being said , I would go under 12lbs on a stock flywheel.

 

I thought it was never safe to take any weight off it.

 

i honestly would not trust taking any weight off of any flywheel.

just purchase a light flywheel.. you'll probably end up getting a lighter flywheel anyway.

 

I would not bother unless your flat broke. I would just get a Comptech FW or what ever you like.

 

exactly, best bet and safer to leave it alone or buy a new light flywheel

 

yeh, and like someone mentioned its where the weight it located, performance flywheels are light and the weight it more centered. it requires less force to be reved up. thus holds less momentum then a factory fly wheel. which is why rpms drop much more quickly and allows your car to decelerate more quickly while down shifting.

 

about how much does the comptech flywheel go for?

 

When I had my '94 GS-R, I had King shave 5 lbs from my flywheel (18 lbs to 13 lbs). New ITR clutch, lighter fw, and new clutch MC. Felt killer. $100 to lighten a fw seems like a deal to me.

An extra $100 for an additional ~5-6 lb. reduction plus a replaceable friction surface seems like an even better deal.


Edit: Realized that my math was off.

I second that

 

how much does a stock ITR weigh?

 

how much does the stock itr flywheel weigh??

Who makes a $200, 6 lb. flywheel? I just posted my story for the budget-minded out there. I'm sure you could safely shave 2-3 lbs. from a ITR flywheel, which is 15 lbs.

I realized this morning that I made an error in my quick math. Nevertheless, there are ~$200 7.5 lb. flywheels (which are what I was originally referring to), and they are an excellent deal, IMO. With the effort involved in removing and reinstalling the flywheel, I would personally prefer to spend the extra money for the lighter, longer-lasting piece, but others might not agree.

 

Does anyone have an idea on how much you can find a comptech flywheel for?

 

Toda is the daddy of all flywheels.

I see them used with a few miles for 2-250 all the time.

 

why do you say it's the daddy? Isn't the comptech the lightest?

yep.

theres more than just weight to consider in rotating mass , its the location of the weight thats the key.

thanks steve!

This is inarguably true, however I have yet to see any objective data indicating that Toda's design has more favorable distribution of mass than other available flywheels (especially those that weigh less overall). I'd be interested in seeing such a comparison, but obtaining the data would likely prove difficult. Regardless, I remain a strong advocate of the CM/Fidanza pieces, which IMO are excellent in both performance and value.
