OEM flywheel weights in at about 26 lbs.
This one weights in at 13 lbs.

Less reciprocating weight means faster acceleration. :D

The engine can now spend it’s time accelerating “other things” instead of those extra 13 lbs.

For road racing, and aluminum flywheel is the way to go as it helps you accelerate out of the corners. I don’t know about drag racing, but I would think it would also help. Anyone have any experience with an aluminum flywheel and drag racing? :2huh:

I know I have had many, many "discussions" with SBC racers that say a heavier flywheel is better for drag racing. I personally think they are insane, but their argument ("stored energy") does have some merit. :leftright

Has anyone elso done this? If so, how was your experience? Keep us updated on this daily driven. The ebay listing describes alot more power.

For pure drag racing, you want a heavier flywheel. A heavy flywheel has more momentum. If you notice in drag racing the revs are brought up and then a huge strain is put on the engine when the clutch is released. the more momentum you have the harder it is to stop you. Is it easier to stop a remote control car going 5mph or a train going the same speed?

Yes, I agree that on lauch the extra weight is good. But, and this is my point with all my friends: once you have to start accelerating, the heavy flywheel is a detriment. It's funny because all my friends are spending huge amounts of money on lightweight pistons and lightweight connecting rods and then bolting this big honking chunk of metal to the end of the flywheel. (Yes, I know the lightweight stuff helps when it has to stop and go the other way... :D )

I wish I had a side by side test of aluminum flywheel vs. heavy steel flywheel in a drag racing environment. :leftright

Anyone ever seen that comparison? :2huh:

I was looking into putting a flywheel into a 01 cobra when I was swaping its clutch but after looking into it. I found out that the aluminum ones are not so good at all for drag racing cause they can't take the abuse of the launch. I have even seen pictures of shattered aluminum flywheels because of a hard launch. However they are supposedly excellant for auto cross.
