alright so a lightened flywheel increases how fast u get to your peak rpms and gives it a little more power in the top...



and a heavier flywheel increases torque?



is this correct?
Click to expand...


imagine getting a piece of rope and one having a 1 lbs weight and the other having 25 lbs.

The one with 1 lbs spins up quicker and is easier to stop.

The one with 25 lbs takes a while to get up to speed and takes alot to stop.

An engine reacts the same way.

Although it does take hp to spin up the heavier weight, once it's spun up, it will stay there.

Physics will teach you this... Mass once in motion will stay in motion unless other opposing forces are acting upon said mass.

Hope this helps.

It will also lower your top speed.



Using the weight (of the fly) your motor uses the heaviness to help it from slowing down in between power cycles.



I don't think your torque is neccessarily increased, but the effect (and location of the peak) definately is. With lower rotating mass the motor can accelerate faster, but not necessarily generate more power.

hahahaha.. who cares. the flywheel is the LEAST of your issues!



Though, believe it or not, depending on the weight of the Jeep, you might want a heavier fly. You'll have to set it up and then determine what's best.



Weight, wheel, size gearing, how loaded your daughters diaper are.. they all matter.
