I'm considering either a 9.25 pound Spoon or an 8.6 pound Toda (in which more of the weight is removed from the edge, so the difference between the two will be even greater than the physical numbers here).

For turbo, I've heard not to go too light (under 7.5 pounds or so I think is what Ben says).....Dustin has an ITR 14 pound flywheel and says he wishes he went lighter.

What is really the ideal weight for a turbo car?

 

The speed you build boost is related to engine load. So wouldn't a heavier flywheel build boost faster? Of course a lighter flywheel is funner to drive.

I use the Clutchmasters on my SOHC. 7.5 lbs or so I believe.

 

stock.

 

hehe, alright maybe instead of just listing the weight, tell me how you like your lightened FWs.

 

I am planning to use a 12lb flywheel on my car. It seems to work ok on Rocky's 670whp race car, so I figure what the hell, it'd be good for me too

 

Cant you just machine your stock one so its lighter? Wouldnt that be cheaper, because I might do this is there isnt any draw backs. Even tho I do recomend stock, I might try it just for kicks.

Machining the stock one so that it is light is not a good idea. It will become very weak.

 

I love mine. I bet it would rock on a DOHC

 

My freind had his stock flywheel lightened to 12-13 lbs by comptech, and he has been running it for almost 2 years now. If the machine shop know what they are doing it won't be a problem. Too bad Comptech doesn't do it anymore.

 

My Turbo is not in yet, but I had OPM lighten my stock flywheel to 12lbs when they put the Quafie in. It is nice, but not lite enough. If I had to do it over I would look for a 9-10lb flywheel and use that.

 

if you can get a machine shop to do it, it's safe. If they don't break under 670whp and low 10 second timeslips, they aren't going to break if you're making half that power. Mine cost me 200 to be lightened, balanced, and resurfaced. I've been told that's kinda high priced, and others have had it done for less.

 

why not just use a ITR flywheel i think it weighs around 13 pounds

 

actually i think ITR flywheels are 16.

 

15.

 

I have the Clutch Masters also and i have no complaints about it. It seems to take abuse well but im sure that is not an issue with most flywheels.

 

By that theory, a car full of rocks would build boost faster

 

BTW, boost is built by flow and EGT. Load in the honda sense is the same thing as manifold pressure. MAP input to ECU = load. This is why throttle position and RPM are the primary contributors to the onset of boost.

good ol Dustin to clear things up.
