I know that a higher mass flywheel increases torque.

But has anyone tried using gearing to off-set the loss of torque from a lighter flywheel?

As an example:
factory flywheel with stock gearing
vs
an aluminum flywheel and two cases, one with a 4.0 one gearset

any thoughts?
 
Are you looking for more HP? You could try a flywheel from a 22RE Celica...

I guess more gears would overcome the lack of torque, but I think in overall driveability you'd miss the torque....

HP gets you going, torque keeps you going..... :D
 
I don't think it is worth having to re-gear just to get it back to how it use to be. I don't see how it would actually help out because the heavier flywheel helps you get off the line a lot easier than a lightweight flywheel. It would actually hinder your top end quite a bit since you would have to re-gear just to accommodate the lighter flywheel.

I'm thinking that you have your logic backwards. I think you would actually prefer a heavier flywheel with the lower gearing (4.0 to 1).

All the lighter flywheel will do is allow the engine to rev faster. That really isn't an issue with a 22RE. What is an issue is to keep the vehicle moving forward between gear shifts and to then rev the engine back up after you let out the clutch. By going through another set of gears you create more resistance for the engine to overcome and, therefore, would need a heavier flywheel to maintain enough inertia to increase rpm without delay.

IMHO, you don't stand to gain anything with this set-up and actually would find it detrimental.
 
How about these two scenarios,

one you are on the street, you would have a quicker rev for usual driving,


your logic related to shifting off road is correct, however- it would seem to apply primarily if you were trying to accelerate up hill.
If you were on a steady climb in the correct gear, with the correct gearing, then you would be able to maintain movement without need of the heavier flywheel to maintain momentum
 
The lighter flywheel doesn't have the inertia that the stock one has, so when you engage the clutch the engine is going to slow down a lot faster than with a heavier flywheel. I still don't see how a lighter flywheel will help at all with a 22r.

x2!

Maybe if you told us what you were trying to accomplish we could understand a little better. Are you trying to go from 0 to 60 in 15.9 seconds instead of 16 seconds....for example? (That's assuming downhill, of course....)

If you have dual cases and one with a 4.0 you're probably rock crawling, so a heavier flywheel would be better.

And with that setup it wouldn't be worth the $$ to change from the stock flywheel to a heavier or lighter one. Keep it stock and you'll be fine .
