Turbo build

Flywheel weight doesn't significantly affect turbo spool up time. The only weight that really matters is the turbine and compressor wheel weight.

I was under the impression that the quicker the motor revs, the quicker exhaust will exit and the turbo will spool up quicker resulting in less lag.

Please correct me if I am wrong, I really don't know much about forced induction. Thanks for your help.
