I've heard quite a few things about lightened flywheels. Mostly from the Mustang side of the house. How drag racers really don't want to lighten it due to you need the mass down low to get you moving.
would this be the same on the CSVT?? I'm looking at getting the LSD, upgrade the clutch (mines slippin under n2o), and a lightened flywheel to lighten the load since the lsd would be adding more weight to the rotating mass in the tranny. Is that the right approach? how much weight does the lsd add???
Also, anyone read the article in MM&FF about the S/Ced Focus who got the 'custom' Aasco lightened flywheel? That's whre I got my ideas from. Lemme hear what you think.

I got a good heavy duty clutch I will sell you if you decide to go with a regualr flywheel. I could not tell much diffrence in the aluminium and steel flywheel. The aluminuim flywheel reved quick but had allot of bad rollover sound. It was like rocks rolling around in the tranny.

That's the clutch, not the flywheel making that sound. I bet your clutch doesn't have springs on it right? That's why it chatters!

It's going to rev faster with the lighter flywheel but I think you will lose some of your low end. That is why the regular Duratec's do just as well if not better than SVT's at AutoX. I make a little more power down low where as the SVT's powerband is higher.

right, but my thinking is the LSD will ADD rotating weight, and the lighter flywheel will deduct weight, thus evening it out....correct?

Only relative to roadspeeds on an LSD,makes little difference to engines ability to rev......

Nothing I would want when driving or especially autocrossing... Also about the powerband crack. STAY IN IT! It is pretty easy to do (4k-7k stock) BTW - The SVT's powerband is longer than the normal Duratec as well. Give me the lighter flywheel anyday. Once you are going ~5mph the lighter flywheel beats a heavier one easily just using physics alone. However another thing to think about. From a dead stop it is easy to smoke the tires at 2500rpm when starting. Raising that to 3000 or 3500 rpm with a lighter flywheel should actually improve your times because it's already higher up in the rpm band. Also take into account the significantly lighter rotating weight and it will accelerate faster yet... THIS IS NOT A DRAG CAR! by the way...

Thanks Demon, I was waiting for you or Terry to chime in. You broke it down potatoe head style for me thanks, that makes sense.... And WTF CSVT isn't a drag car? Since when?? Well can I pretend? :-D Originally posted by DemonSVT: Originally posted by todras:

With the lighter mass yet it was louder with the aluminium flywheel. After I put the steel back in it was quieter but it still had a little roll over sound. Rtstabler choose your clutch wisely if you decide to go with the aluminuim flywheel because some manufactures require flywheels to be grinded so there clutchs seat properly. (Ram) Costly mistake for me. I was so fed up with the flywheel I sent it back and now I am 400 dollars richer. What do I know about power diffrences I only had both in my car. butt dyno of course. Not worth it! My two cents :p

You and I both...  It does do quite well at the autocrosses though...
