Greetings,

Yes, I'm trying to avoid spending too much time on this, but I'm tempted to try adding more significant flywheel weight to the single rotor, to see it it will behave better. I realized this isn't an ideal solution to an already heavy engine, but it might still be worth trying.  My question is how much weight should I add to make sure this will get rid of the torque reversal issues?  I understand that weight added farther out from the center has more effect than weight close to the center. Ideally, I would plan to make a ring, with about an 11" OD (or as large as I can without interfering with the starter ring), and about 7" ID. This would bolt to the redrive side of the dampener plate, using the existing 7/16" bolts. I made an estimate of the weight of steel, by measuring the volume of a 4130 plate, and weighing it. The result was 4.5 oz per cu in. My best estimate is that I can get close to 10 lbs, using a half inch thick piece of steel. Unfortunately, this will be quite time consuming, and tough to fabricate, balance, etc.  The other option is to try to add more weight than I did before at the 4 bolt locations. This is a much easier plan to implement, but I'm afraid I'll be lucky to get 5 lbs added using this method.  Anyone want to take a swag at how well this would work?  Thanks,
Rusty (resistance is futile)


Rusty,

 How about one of the aluminum flywheels often
sold to racers?

Rusty, I have a Racing Beat aluminum flywheel just laying around gathering dust. It cost me over $400 new.
