Where can you find a true 9.5 lb flywheel
 

It seems to me that all the flywheels are advertised as 9.5 lbs with out counterweight then 12 lbs with it. Is there any flywheel that weighs 9.5 with counter weight?

Explain to me the importance of the difference. The counter-weight weighs a little over 3 lbs. The lightest flywheel I've seen is 8.5 lbs. How much lighter do you need? There has to be SOME mass to the flywheel....

Tell you the truth,i just was wondering if there is a 9.5lb flywheel, it just seems like it's false advertised.So technically lighest flywheel you seen is 12lbs.It should say 12 or 13 lb flywheel. I'm in the market to buy a flywheel,and just looking around and wondering what is the lightest. I'm assuming 8.5(12 lb) is the limit.

I don't think i've even seen very many flywheels that include a counterweight, so the makers of the flywheel just address their own (i'm guessing).
I've heard of people using the counterweight off an auto FD... woudl that make things lighter?

i have seen a whole clutch and flyweel assembly that weighs something liek 12lbs TOTAL!!! but that was a race ONLY kit...

The racing beat flywheel comes with a counterweight, and that is 12 lbs total. It also has a replaceable face.

I don't think you understand the idea of the flywheel. The 9.5lb flywheels actually weigh 9.5lbs. The counterweight is not really part of the flywheel. It does not spin with the flywheel, so the rotational mass is still the 9.5lbs, not 12. The counterweight attaches around the eccentric shaft with a tab angled so that it provides a small amount of torqe force to the engine to reduce throttle yank. I have the racing beat flywheel sitting in the shop now. It weighs 9.5lbs and it is light enough for what the car will be used for. Anything less than that and I would want to have a different engine in the car because it'd drive like a motorcycle. Clutch engagement would deffinitely suffer going lighter than what's available for street application. If you want the car to rev faster, just drop in a 3-rotor and I think you'll be satisfied.

correct.
