Flywheel question

[Fiorano]

Before delivery, I am planning on having smooth tubes w/K&Ns as well as a Corsa exhaust installed. I've been debating about a lightwt flywheel. Is there any real reason not to do it aside from spending more money? Thanks in advance for any opinions.

I'm curious why you say that? I've heard it's a good track mod. I hear that it allows the engine to increase and decrease rpm faster since there is less rotating inertia. You didn't find that to be the case or what?

Phenomenal track mod, and used by virtually every driver in the Viper Days Racing League. Most of us just like the way it zings right up to redline -- it will keep you awake and ready to shift at a moments notice.

What Bill said!

Yup, put 2 Vipers next to each other, one with a lightweight flywheel and one without and gun em' both. The Viper with the upgrade zings to redline muuuuuch faster then without. A must for road racing.

Another Viper owner (97 GTS with approx 500hp) and I (2000 GTS with approx 475hp) had a side by side race. I could stay with him up to my shift point where I have to shift and he has about another 200-300rpm to go before shifting.
The flywheel definitely makes up for some loss in horsepower because my engine rev's up a lot faster than his. I have since driven a 97 and a 99 GTS and found the engines to rev a lot slower than my car.

If you are road racing, I think the aluminum flywheel is a great improvement, the car really pulls hard off the corners, you can make up for some horsepower deficit, but you have to shift a little more than a car with more horsepower.

I agree w/ Bill P et al.........but the launch technique is skwewed higher for dragsters.

P.S. There is a new FW in town, and PartsRack debuted the 4-Chromoly puck AL flywheel at VOI-7.

Instead of 1 steel friction ring, which dragracers and S/C cars are often warping like a rippled potato chip, this FW has 4-pucks of chromoly steel. Absolutely cant warp. Only $25 more than Fidanza.

Bonus: Comes factory balanced at no extra charge......balancing costs $75-$100 more with Fidanza....

Qustion,On the light weight fly wheel a lot of manufactures, different makes of cars voids the warranty because it is part of the balancing of the crank as is the damper. has any one checked with dodge with this.

So how is launching affected for drag racing then?

I have used Aluminum and the stock Steel FlyWheel. After Warping the Friction Ring in the Aluminum FlyWheel did I switch back to Steel. When dragracing do I absolutely prefer the steel Flywheel. You don't loose RPM between shifts as rapidly as you do when you have the Aluminum Flywheel...
As long as you have rpm and power enough is launch not affected of your choice of flywheel. (With DOT Slicks)
