hi. i was wondering if it would be a good idea to get a lightend flywheel when you supercharge. would a 9-10lb flywheel be best or would a itr flywheel be better? thanks alot

 

Lightened flywheel can't hurt, unless you are a drag racer.

 

im confused. how would a lighten flywheel hurt a drag racer?

granted people say you lose torque etc...

thats not true. your rotating mass is lighter however (flywheel) and therefore easier to spin. I would not call that a loss of torque however.

 

lightweight flywheel= regardless you're supercharged, turbocharged, or naturally aspirated.

 

Nothing to do with torque. For those hardcore drag racers, there is a loss of momentum. The lighter flywheel will not store as much energy when you rev up for launch. I dont' drag, so this is not a concern for me.

For anything beside a drag launch, there are no advantages besides ease of take off due to the extra weight of the factory flywheel.

Less rotating mass is gooood. It allows your engine to spin up quicker. I don't think this is measureable as torque increase on the dyno though.

 

...and it means less wear and tear on your motor! Unless you constantly rev the **** out of it...

 

Your revs may also drop quicker with a lightened flywheel

 

would a supercharged car be faster with the lightend flywheel? thanks

 

Same rules apply for a supercharged car. It is a good mod. Do it if you have the money.

If you just want to be faster, there may be better mods out there though. Pully upgrades etc.

 

so basically a lighter flywheel lets you rev up quicker. so would your times improve? i know there is no hp gain so im trying to figure out if i should get one for my b20 that will be turbo eventually. im going to put in a new clutch and so im trying to see if another flywheel would be worthwile, or just spend it on something else.
