balancing clutch/flywheel

[Enchanter]

...my understanding was id lose torque from a lightened flywheel in an NA, something i rlly want to hold on to....

You dont actually lose torque with a lightened flywheel, all it does is change the way the torque is delivered to the drive train. If you have a light car I would go for a lighter flywheel, if the car is on the pudgy side a heavier flywheel is better.
A flywheel will store as well as sap the engines momentum, so off the line an engine with a light weight flywheel will need a few extra revs to replace the lost "torque" or momentum of the flywheel. Once the car is rolling the engine will be able to gain revs quicker as it wont have to spin the weight of the flywheel with it.

Good explination Enchanter.

Always compromises to consider in any build.

well i picked up the flywheel and clutch, the guys did a nice job machining it, really nice ppl to talk to as well, his name was Rob from Transmission physician in hornsby. he said it wouldnt need balancing because it was balanced from factory, and that unless it was gonna be revved beyond 14 000rpm then it wont need a balance.
