Tracy,
   Curious= as to the weight of the aluminum flywheel you are buying as most
I have seen are not = much if any lighter than the steel versions by virtue of
the the mass th= ey must have for the needed strength to survive the rotational<= /div>
forces put on them a= t up to 10,000+ rpm in racing use..........I realize that our
A/C use will not&nbs= p;turn at these rpm's but you can only reduce weight so <= SPAN style=3D"RIGHT: auto">much
without compromising= structural integrity............

Subject: [FlyRotary] Fl= ywheel thickness ?

Question for David, Kelly or anyone else p= laying with lightweight flywheels.  I have one on the way but won't se= e it until I get back home in October.  I'm working on a new design to= replace the stock flex plate and need to know the thickness of the lightwe= ight flywheel.  Every picture I see of them appears to show an almost flat= disk which would imply that there is MORE room between it and the redrive  adapter plate than there is for t= he flex plate which has about a 1 1/4" dish in it.  BUT,  much of= the discussion seems to imply that if anything, there is LESS. 
<= BR>Anyone able to tell me the actual thickness of these aftermarket lightwe= ight flywheels?

I'm looking at the aluminum versions for weight reas= ons and also because the iron friction surface is removable ( for even less= weight). 

Tracy
