Default can there be too light of a fly wheel?

aight so i orderd a 9lb flywheel, i figured the lighter the better, but my boy told me that he has seen someone tryna go up a steep parking gurage and he wasnt able becuse the engine was bogging out? not enought rotational force or somthing...it doesnt sound right to me but im still not certifyed at HONDA eather?

when it's too light, you can rev it up and then slow down quickly... like at a stop light or something, and the car will shut off.... not enough rotational force to keep things turning... not sure about the parking garage thing though

I could see it being a problem if the accepted technique for going up a steep hill was to redline the engine, close your eyes, and drop the clutch, letting the flywheel's momentum carry the car up.

However, if the driver of the car used the engine to drive up the hill, I don't see how it could be a problem...

The problem here is the point between shifts. With a flywheel thats TOO light, your engine will drop out of optimal range when you shift, resulting in you loosing power and time.

The ideal flywheel weight would be between 9-12lbs.

Are you supposed to lift off of the throttle when you shift?

I read somewhere that if the flywheel is too light, you can actually lose inertial toqrue.

I completly agree. It really depends on what you use the car for.

(Daily driver) Street = you are going to have to use something a little heavier so you don't screw up idle and start off

(Track) Racing = go with a light wheel since RPMs won't drop much below 4-5K, and you get best acceleration due to reduced rotating mass

That's my two cents, but hey it's a free country, due wht you want.

i think that it isnt anything to worry about.

9lbs is a good point between too light and too heavy, basicly between super light and stock.

you shouldnt have any problems i had a hdss with a exedy 9lbs flywheel, the rev was alot faster than stock, but it wasnt anything that was undrivable or cause ANY problems, basicly just felt alot faster reving than stock

I have a 6.3lb flywheel, 3puck solid hub disk, and an extra heavy duty presure plate. I wouldn't want to get caught in traffic with it.

he brings up a good point. how the flywheel is will depend on what kind of a clutch you have
