i agree. I just dont understand why solo is trying to fight me then every1 on this. This is what i said again..... If 2 Robots with the exact same driving skill racing in a DE and a HR the HR will win and i have already said that. However ur trying to contradict me saying my Mods didnt help my performance which is kinda stupid. If the flywheel lightens up weight(revs faster) and a pulley lightens up weight and volks lighten up weight and racing seats lighten up weight and ripping out interior lightens up weight...What does all the mean? A faster car
. Its u vs everybody else. I have beaten Z32TT and Rev ups and HRs. and I said with my 1st post DRIVER IS THE BIGGEST MOD and u declined that. well if my mods didnt help me win the race...PLEASE tell me how i won?

I've been racing at the strip for a decade and the flywheel debate has been in effect during my entire track period.
It has never been "proven" that a lighter flywheel is better or worse. But if it "feels" to you like it is, then more power to you. Yes, a lighter flywheel allows you to rev up faster. But then you lose momentum due to reduced mass. In my experience it is always better to error on the side of more power. Having more momentum means having more power to me, so you know where I stand on this.
I actually seen two old men with decades of racing experience get into a fist-fight at the track over this once.

I also took the liberty of your fixing your grammatical mistakes.

lets end it with note....taken from
http://www.vetteweb.com/tech/0407vet...ion/index.html
"The important thing to look at in this test procedure is the time to speed relationship, not necessarily the increase in horsepower. Keep in mind the test device we used was an inertia dyno. A flywheel does not make any horsepower, but it shows up as a horsepower gain because you have reduced the inertia on an inertia dyno. So you need to look at the reduction in time to speed that was created by the reduction of inertia. We went from 14 to 11 seconds to 145 mph on the stock Z06. What that tells you is how the car is going to feel on the street. It is going to accelerate quicker to the redline."

Exactly. Never been proven. It feels better but it never shows it at the strip or the dyno. So no the car is NOT faster.

it's like changing speeds on a ten speed bike...the heavier gear takes more time to get going but once you do your flying, and the lighter gear spins like crazy and u take off faster but you dont move any faster compared to the momentum of the bigger gear.
(there's no weight on the gear of the bicycle only high or low, but you get the jist of it.)

Another thing they didn't mention was the need to rev higher when taking off. With less momentum the vehicle would be more likely to stall on take-off at the lower revs.

You have less STORED power, so you need to either rev higher, or let the clutch out slower.
In a racing situation, you'd be launching anyways, and stored power in a flywheel is totally insignificant relative the the amount of power necessary to turn 4 wheels and move the car.
Calculate how much energy a 14 lb flywheel has, vs a 27lb flywheel, both spinning at a given RPM.
Now calculate the energy required to move 3500lbs (car + driver + fluids) including the energy required to rotate 4 masses each weighing roughly 45 lbs (we'll assume it's a solid mass to simplify calculations for both the wheel/tires and flywheel)
