im about to order a clutch and flywheel for my build and i have ben reading up on what other people have experienced and i came across someone saying that ull loose torque with a light flywheel on a boosted setup...thoughts and opinions???? ill be running around 350 to 400 hp on a ls vtec turbo setup.fully built.will a lightweight flywheel make me loose torque???

 

Reducing rotating mass will not make you lose torque.

 

thanks for the reply.thats wat i was leaning toward...anymore thoughts or opinions anyone?

x2

 

you dont want a lightweight flywheel on a boosted engine.

OK , and hes asking WHY , or will it reduce torque .

I'd like to know as well.

 

The lighter the better. It doesn't make you fall out of boost, you just have to shift faster. The only time a light flywheel is bad is if you run out of revs trying to launch on large slicks. This happens because your engine doesn't hold enough momentum to launch without bogging. But if that happens, I'd say running smaller slicks would be the better solution since a heavier flywheel robs power and torque across the entire RPM range. People also seem to ignore the fact that their ginormous aftermarket rods add a ton of weight to the rotating assembly.

Having said that, I'm running an 8lb flywheel. Had the same flywheel on 2 engines, 3 setups (N/A, JRSC, turbo), and wouldn't have it any other way.

BTW, this topic has been beaten to death a million times in the archives.

and what do you gain with it on a turbo'd engine?

dont forget about drivability..

You mean other than more power and faster acceleration? What more could you want!

"Driveability" isn't an issue. Give yourself a week or two to adjust to it and you'll never know you even have a light flywheel. Although it does kind of suck when you borrow a friend's car for a few days, then go back to your own car and start stalling out because you forgot how to drive it...

Good real world scenario explanation.

 

The lighter flywheel will have less momentum when you shift into gears causing the engine to feel like its stumbeling a little more. Poeple may interpret this as a loss of torque, when it is in reality the engines willingness to change RPM's quicker (coming to down to meet a transmission at a lower speed, like 0 MPH).

 

i used to drop out of boost using a 7.5lbs flywheel

i went back to stock.

 

yeah ive noticed some lighthweight flywheel applications to cause trouble launching turning it into a bog or broil situation.

 

i just changed from a 7.5lb flywheel back to my OEM gsr flywheel. Im pushing about 320whp and i sware it feels alot sower! i didnt think launching was that hard with the lighter flywheel. Maybe it is just me but it doesnt feel the same...

 

my engine came with a light flywheel. no idea what weight but i hate it. its a bitch to drive and you have to shift as if you were racing jst not to have the car studder. when i get the motor out ill be going back to a stock flywheel.

 

stock FTW!

i guess some people just dont realize a lightweight flywheel isnt worth it on a boosted honda. just turn the boost up a 1/4 psi if you want the extra power of a lightweight flywheel lol.

 

yes, with a light flywheel, you have to shift like if your racing.


imho, light flywheels are for NA

 

I agree lighter is better just balance all your internals with it

 

A light flywheel works for me. I'm a little concerned about harmonics but ignorance is bliss.

 

lightweight flywheel here

had no problems with it when i switched from oem , unless you dont know how to drive then you will get used to it very quickly...

also to whoever said to just turn up the boost... that works in some situations but i would rather have a more efficient engine to begin with and run less boost

even if its just a 1/4 of a psi ? lol

I was thinking the same thing. One trip around the block was all I needed to adjust. And when I'm driving on the street I don't shift fast like I would on the track, I shift slow and smooth and I've had no issues. I haven't found any reasons to go back to the OEM flywheel.

 

Sorry to continue to the offtopic but a lightened fly was one of my favorite mods to my car.
