Can U Get Your Stock Fly Wheel Lighten

[jas_r34]

no, you must buy a lightened flywheel from an aftermarket company...try ebay

[abs-lsd]

Yeah, you can. A machine shop could take care of that for you...get a couple of pounds off it. But then you wont save much money over a proper flywheel and also run the risk of a nasty failure.

A good machine shop should be able to do it for you. A local one here in BC charges $100CAD to lighten and balance. He has gotten rave reviews from many people including the local autocrossers. As long as the lightening and balancing has been done properly and not excessively, it should be fine. I'd try to hit up the local car forums to see if there are shops near your area that's been recommended.

1. You can lighten the stocker but will you feel safe with one?
2. Resurfacing is a different thing which most shops can do.
3. I would just get an aftermarket flywheel with all the hassle. Think about it...New product, made lighter, and tested properly.

i was going to say, if you're going to remove weight from the stock flywheel, how are they going to ensure that it's balanced properly?

[YK86]

Like I mentioned, a good shop will lighten AND balance it. My buddy has a lightened flywheel done by the shop I mentioned in his h23. It's been 4-5 years now, used and abused with no problems what so ever. Have another friend who bought a lightweight aluminum flywheel had to get it balanced at said shop because it wasn't balanced from the factory properly. Mind you, his was a cheap Ebay flywheel so maybe he was unlucky.

But I do emphasize that it is important that whoever does the lightening have a credible rep. The shop nearby does machining and precision balancing for all sorts of machinery and has been in business for quite some time.

by how much do they lighten the flywheel? is it comparable to an actual lightened flywheel you can buy?

[lowproki]

okay dude think about this way ur going to lighten your flywheel it will work but how much is it going to cost $100-up.

How much does a aftermarket one cost $100-$150 which one u think is better.

Its only worth it on expensive cars that they cost alot . Like mustang,camaros their flywheel cost from 300-up. Honda is commend and any brand makes them so thats why its cheaper. Just stop being cheap and buy a aftermarket one because your still going to waste the samething.

I just bought one for my car I bought 8lbs. Flywheel and clutch for 228.65 shipped it was a combo

I bought a flywheel for my SR20 cost me 300 just enjoy u have a honda

It needs to be done by someone who really knows what they are doing. If done incorrectly the FW can be dangerously weakened, people have been ripped apart (literally) by exploding FWs bursting through the bell-housing and firewall like they weren't even there. There is an absolutely huge amount of kinetic energy in a FW spinning at higher rpm...

No metal should be removed from near the centre of the FW as this is where the most stresses are and where the least gain is to be had from removing rotational mass. The closer to the outer FW edge X mass is removed the more affect it will have on engine response and the less energy wil be 'lost' to the wheels. If you remove X mass near the centre of the FW (i.e. near the axis of rotation) it will have very little affect on rotational inertia, but if X mas is removed near the outer edge it will have a much bigger affect. Two FWs of X mass can have very different characteristics re rotational inertia (engine 'reviness', power required to rotationally accelerate the FW and time it takes to rotationally decelerate the FW), depending on just how that mass is distributed within the FW. You want most mass near the centre and least near the edge, both for strength and for the characteristics we want from a light flywheel.

Keep in mind that stock FWs are typically made from cast iron which is a relatively brittle material compared to steel, which many of the aftermarket FWs will be made from, so you should never use an aftermarket FW as a template for lightening a stock FW...

Around here (BC Canada), buying a lightened flywheel made by a reputable company costs $350 to $450 after shipping, taxes, broker fees. A new in box Exedy that a guy was trying to dump was $250 and that was considered a great deal.

I'm not saying you should "cheap out" or anything. If you can afford it, get the aftermarket. All I am saying is there are reputable machine shops out there that can do it properly, have it last a long time, and priced reasonable too.

I haven't priced aftermarket FWs, but I expect the $ situation would be quite similar here in Australia.

It needs to last more than a "long time", it needs to last effectively forever (do you want to die soon, or long time later?). Lightening OE FWs is certainly a viable option. There will be people who know what to do and what not to do, I'd look for a racing engine specialist who's been around long enough to have been doing this sort of work from a time when light aftermarket wheels weren't common or easy to find. And, I'd be relatively conservative in the mass removed.

yah that was me, heh, i decided to give it a shot. hopefully it works, ill be keeping the stocker just in case. IMO reasearch more and do what you feel is right and comfortable.

try a reputable machine shop or buy one, i bought one and next week the bitch gets horseshoed in. hopefullly it works well. 12lb F1 racing wheel. havent heard any bad things about it yet and with the clutch combo it was 300 to my door all in.

Hey, nice to see another VAC member on here. Keep us updated on yours. Did you get yours online or local??

I'm helping 604_SE with his swap. He picked up the Exedy from another VAC member. We'll see how he likes that.
