Ok, here is the deal. I am a little confused and I really want to understand this...

If a lightened flywheel doesn't substantially change how fast a car physically accelerates (I know it does to some degree but mostly its the feeling of accelerating faster that people talk about) but it does make the RPMs increase faster, how doesn't it make a vehicle's 0-60 or 1/4 mile times noticeably better?

I say this because at redline (or at any RPM rate for that matter) in 2nd gear a H22 with a stock flywheel and a H22 with an 8lb. flywheel are both going the same speed. So if the H22 with an 8lb. flywheel gets to redline considerably faster then the H22 with the stock flywheel, how isn't it accelerating considerably faster also?

Be nice to me. lol.

 

lighter flywheel will only increase rev ability.. if you have no traction issues at the track use a heavier flywheel to get the car moving faster but if your car spins them like crazy use a lighter one for less mass and less shock on the wheels

 

That makes no sense. Everything I have read states the exact opposite. A lightened flywheel makes breaking traction easier and a stock flywheel makes launching easier. Not to metion you didn't answer my question at all.

 

if you have more mass moving at 8000rpm how is it gonna give you more traction when you shock the wheels with that?

 

I actually meant that having a lightened flywheels makes it more difficult to launch. They like to bog with slicks and then if you give it too much, they will spin the wheels like crazy. I think the inertia of a stock weight flywheel is easier to control.

There is a reason why many, if not most drag racers use stock weight flywheels. I don't know if you know who Earl is but he is one of the main advocates for not drag racing with a lightened flywheel. But I could care less about drag racing, straight line speed on the other hand is not too bad.

 

A heavier flywheel will make launching easier. Once you get moving though a lighter flywheel will allow better acceleration. They each have their upside. If your not looking at drag racing and are more into autocross and road course action then a lightweight flywheel is a good choice. I love mine, makes rev matching on downshifts much easier.

 

but you cant get traction with hte heavier flywheel then lighter is the way to go so it doesnt shock the tires as much then you can accelerate quicker down the track also
