I agree that in theory a lighter item is easier to accelerate, but when it gets rotating at such high speeds interia helps it keep going. And more weight equals more interia. So you're not fighting deceleration so hard with a heavier item. Again this only applies at high rotational speeds. At low speeds the lighter items will prevail.
The reason we still toss that theory around is we've had two cars with identical mods except for one with fidanza and one with stock. When racing, the fidanza would always jump ahead in the lower gears but on topend the stock flywheeled car would pull ahead. This is at very high speeds, not speeds a normal KL car would see in a 1/4 mile.
All interia theories aside. Any of our cars can attain the speeds mentioned in this thread with enough power.
top end=nothing there

this is true...imagine u had a huge bus moving 140 mph (yea i know..but just for sake of theory) and a geo metro going 140 MPH ( again..haha)
Wind resistance is gonna slow down the metro ALOT faster than the bus if both vehicles let of the brakes and lt it coast to a stop. So when the metro got to the HIGH mph area it would be struggleing againts that same resistance while the bus (assuming it had the same power to weight ratio) would not have that much of a problem cause it has so much inertia.
