Lighter Fly Wheels

[Mark Red GTS Cooper]

Need to hear any impressions on the lighter flywheels.

I have heard conflicting stories, some say they can feel a difference, and some day they are not worth it.

I would like to hear from owners who have them and hear what they think.


Thanks,
Mark

I installed my Sean Roe flywheel today, ok, I bought the coffee and bagels while Dan Burch, Viper Tech, installed it. Big improvement! I have headers, gears, intake, Roe controller, etc. and the flywheel makes the car feel more powerful and quicker. I surprised myself this evening when the tires broke loose 1/3 of the way into 2nd gear. It felt like I was in 1st! I'm very pleased and, as usual, Sean's price and service were great.

Do you know what the weight (or better yet, rotational mass) is of the stock and aluminum wheel?

Thanks

The aluminum flywheel is 17 pounds. I think the factory flywheel is 38 or 40 pounds. I don't know what the rotational mass is.

The stock flywheel weight is 31 lbs. The McLeod flywheel is 16 lbs.

Jerry,
With my Longacre car scales (that read in ful pounds), it says the stock flywheel is 34 lbs (could be rounding up to next full pound) and the McLeod and th one I offer are both 17 lbs. An insignificatnt difference from your #'s, but stil a difference.

Glad you like your flywheel John. We sent out about 5 of them at the sale price of $449.95 last week.

Well, I was kind of close. Jerry, you're such a smartie.Okay, so what is the rotational mass?

More thoughts on that flywheel.

If you have a car that will light the tires in low at full throttle while TRYING NOT to lay tire - it may be a real clever tuning trick to size the flywheel so that you just avoid wheelspin given a particular tire/surface/HP/gearing condition.

Of course, the wider the transmission ratio, the better this would work because in 3rd or 4th gear, you really would like no flywheel mass since there usually is not a wheelspin problem.

Another concern might be if you had 600 to 800 HP. Here you may wish to size the flywheel so you do not get wheelspin at, say, 100 mph in your lowest, appropriate gear. Forget about taming 1st or 2nd.

This, actually is quite interesting because it appears to be different from the traditional applications where HP is limited: The drag racer looking for a heavy flywheel to launch car with monster slicks/suspension and the circle track racer who wants no flywheel to max accel out of the corners.

It figures - the snake was always looked down upon by humans - hell, most people don't even want to eat snake!
