Stock flywheel
Would a stock flywheel be better then a lightweight flywheel for a boosted Elantra? I have heard that a lightened flywheel on a turbo car can cause a loss of torque? Anyone confirm?

What you heard about is a loss of energy on the launch. A flywheel is a type of energy storage device. When you spin it up some of the work the engine did to get it spinning is "stored" in the weight going around in a circle. When you dump the clutch that energy is transferred to the wheels. Light weight flywheels cannot store much since the storage is locked to the speed of the flywheel and its weight. The actual torque the engine puts out is unchanged if not increased because after that transfer occurs its not having to spin a big heavy ass flywheel. I think I got that right.
In other words, you will need a few more revs to launch, it doesn't hurt your power output or torque.

^^^^ Correct,
It also for me, Has made my tranny alot less Grindy when combined with some synchro-mesh tranny oil. Yet street driving becomes a little more intricate. Even though that only adds to the fun, atleast for me. I have my Fidanza bolted to a CC Stage 4 with a Althier push swap. Works amazingly. Yet, again alot more foot work is involved.
