its different for the STi's. the lightwheel is already somewhat light. the STi's have very short gears and lightened flywheel will call those gears to be shorter. also, they have been know to throw misfire CEL codes.

 

ummm how does that cause the gears to be shorter? i just dont see how that would do anything to the length of a gear?

 

Lmao.....

 

it just makes it rev quicker so theres less time in a gear?

I would just break out a wire wheel and give a rough up and get ride of the heat stress marks

 

This is fun...

Now lets not spread to much mis-information in my thread, lol.

Yes, less reciprocating mass means faster acceleration even if power remains a constant. That is why a 4 banger can out accelerate an equally powered V8... becasue its internals weigh less, hence take less time & effort to move around.

Can you throw a baseball or bowling ball faster? See?

The misfire cells disappeared with the 2005 ECU in the Sti and only occured randomly-anyway when 10 pound flywheels were used. If you do get one, it is harmless.

The 06 STi flywheel weighs 19 lbs and the ACT Atreetlite weighs 15 lbs. A 15 lbs flywheel is not really that lite. ACT does make a 10 pounder for the STi called the Prolite. Anyway the car should rev out a little better from the 4 lbs savings in this wheel.

I will save the stocker, resurface it, and reuse it again if I get back into the Bradenton drag racing. For my intended use at Sebring, this Streetlite should be a welcome addition.

 

so a bigger turbo makes less time in a gear... but each gear is still going to end at the same mph as it did with the stock turbo lol

 

sure, gearing is just a function of leverage... more leverage (more power) = less time till the gear runs out

this is fun..

But wasn't he asking about the flywheel & not a turbo? I am confused again.

 

im just saying because i flywheel just means less rotational weight meaning it will rev easier the gears will still end at the same mph as they did before... what he said is like saying more power will make your gears shorter but really it just makes you get you speed up quicker

 

well said kyle!
