Flywheel..How light is too light?

This is the internet. You're just supposed to talk up whatever you do know as if you're a salesman for it. i.e. I drive a Supra and a Corolla therefore 2JZ is the greatest and so is the 4A and I don't care about anything else because it's all crap since I don't have it. I also have a stack of $20 bills in front of me, therefore 20>50 and 20>100 and 20>1000. $20 bill FTW.

A body in motion will stay in motion unless an equal yet oposite force acts upon it...
so think about this... you rev your motor (flywheel spining) you release the clutch and the "oposite" force being your tires on the road (traction) with the lighter flywheel (if you have traction) the motor will tend to bog easier, or if you over rev to get over the bogging you will spin...
now with the stock flywheel... same situation... you will be able to launch lower and transfer initial TQ easier (getting off the line)...

yeh, with a lighten flywheel, u have to shift a lot faster or blimp the throttle a bit since the revs will drop faster than a stock flywheel.

even if the revs drop, they come right back up if your clutch doesnt slip once its engaged. for example 60mph is a mathematically set RPM in each gear...a lightened flywheel doesnt change your gear ratio.

aint gotta use the clutch to shift during regular cruising, so the dropping rpms wouldnt be a problem...for me anyways, i rarely use the clutch.

The best engine in the world is the vagina, it takes any size piston, its self lubricating, starts with 1 finger, and every 4 weeks does its own oil change. It's just a pity the management system is so fucking temperamental.
trucker shifting woot woot!!!! hahahaha i can do it into 5th gear but i dont want to try it that often ... lord knows what it is doing to the car

I think he means he uses the engine rpms to slip into gear. say at 3rd gear 7k pop out of gear and shift into 4th when the rpms drop to like 4.5k ( not sure on the actual rpm values). it takes some skill and until you get it right a whole lot of grinding but it can be done. I used to do it on my s15 pickup, but haven't taken the time yet on the honda.
