Flywheel weight??

It makes me wonder if it' ll run with so little of the original weight (moment) why do I need a flywheel at all?

If it weren't for my braces, I could cruise with it in my MOUTH & if I rigged up an IN & OUT, I could be a race car pilot!
A friend had a spare motor, without a flywheel, sitting in a "box" made of 2 X 12's & cut a crank hole in it. Occasionally, he would crank it & let it run a few seconds at a fast idle, to keep it freed up & oiled well.

"The original flywheel weight was about 62 pounds so how much can you lighten the flywheel and still have a smooth running engine?"

On the last 3 engines I built I used a modified 350 Chev aluminum flywheel that weighed 12 lb. I also used a rebuilt 9 inch Long type ALUMINUM clutch cover. I like the Long clutch with the centrifugal weights because it takes less pedal pressure to operate.
Two of these engines were mild street engines and they would idle smooth at 500 and lug smooth right off idle.
Light flywheels do not add horsepower but they sure add driving pleasure.

I think we had this discussion before, but I'll reiterate my point again. Ligthter FWs do not add HP, but they free it up and it goes to the wheels instead of being lost. If that is not clear, imagine a 126 lb FW, or a 189 lb FW. How much or the power of each stroke would be left to accelerate. Sure, it's great for a constant speed engine or application. But not in a car.

Hey TerryNJ,
'free up HP' , is the most succinct and accurate explaination, for what 'lightened wt' flywhl does, IMO. I have never seen any reasonable stmt of how lightening the flywhl ..has negative result (s), other than 'if ain't stock'.
