I've had this discussion with Brent & others... this is what I've found:

IF you are stop-starting then the slightly heavier flywheel is best (ie: a little over 1% of car weight - ie 2000# car 20-25# flywheel). I'm not talking 40#

I know it's not the "sexy" or preferred "opinion", but none the less, it is what I've found.


The lighter fly wheels are great once the car is moving, ie: racing or Kirkham canyon drives, etc... but it can be tiresome slipping the clutch to get them up to overcome standing inertia from a dead stop all the time. You'll likely wear it out sooner.

Truth is 22# flywheel is still pretty light and at the back of an FE with 600ft/tq will not slow the sucker down much.

Just be honest with the type of driving you will be doing. This is indeed one of the hardest parts when deciding on your build.
