They have a super light 8 pound flywheel, and I'd like to put a light flywheel in next time I do my clutch (nuther year or so), but...

I've read posts here about flywheel bolts backing out becuz the aluminum flywheel expands and contracts at a different rate from the OEM steel bolts. Obviously, this is bad. Does anyone have experiece with the Unorthodox aluminum flywheel?

My other option would be the Zex 10 pound flywheel, which is steel. Still really light compared to the stock CRX flywheel, and about the same price. Any ideas as to which unit would be better for a car that's street driven and raced as well? thanks

 

I got an 11lb SRR chromoly flywheel for $200. I haven't put it on yet, though.

 

I have a 7lb aluminum flywheel, haven't had any problems.

 

I used to be into the chromoly flywheels over the aluminum ones. Now I've kind of reversed my opinion mainly because with the aluminum ones you can simply replace the friction surface instead of the whole flywheel. Basically they're both good.

ACT just came out with a line of chromoly flywheels and the pricing is pretty good right now. Check out the page at Options Auto, they run from $224 to $251 depending on weight which is one helluva deal.

 

Ok, after talking with people that have had these flywheel bolts back out, I'm fairly certain that this results because there is no mention in any of their literature of using loctite. Using red loctite with the spec'd torque should eliminate this problem. If you're really concerned, there is still no reason to overlook an aluminum flywheel if you really want one; you could always have the flywheel bolts drilled to accept safety wire. :dunno:

 

Hey, did you know loctite was fabed up in WW2 as a quick way to bandage soldiers? Medics didn't have enough time to bandage them traditionally so they just made this goop that would bond skin shut. Next time don't be afraid to use it seal your skin shut.

 

are there any disadvantages to putting in a lighter flywheel?

 

How do you get it off? The same way you get it off of fasteners? Blowtorch?h:

 

my guess is it was a less permanent form than the type of stuff you need to use a blow-torch to get off. they do make something like that in a chap-stick type container which you use to quickly patch up razor cuts from shaving. i'm thinking that's the kind stuff they probably used back in ww2
