All other times it will be superior performance wise.


Demon not to ba a naysayer but mustang and fast fords did a test and they showed the oppisite. Power increase 1,2,3 and then leveling our on top. I know you don't like the stangs but check out the mag its very interesting.


I've read the article.

You seem to forget that dyno testing is done AFTER the wheels are already moving. (also it is not accelerating the car's weight only rolling the drum)

Read my post again & tell me how what I said could be construed as wrong???

A lighter flywheel has less mass (stored inertia) to get a car moving from a stop. This is simple physics. Once the car is sufficiently moving this drawback of a lighter flywheel is gone.

Dyno testing normally starts around 2500rpm. The wheels are definitely sufficiently moving by then.


Good enough for me!
