Lightened Flywheel – Would you do it again?

[Jerry Dobson]

I have read previous posts on this subject and still did not get a clear answer from reading them. I am removing my motor. I have a question for anyone that has installed a lightened flywheel.

1) Would you do it again?
2) How is the drivability at low speeds?
3) Did you have to balance the assembly (flywheel and press plate)?

Thanks,

Jerry

I found the flywheel to be balanced very well but the oem pressure plate needed a lot of attention. There is evidence of it being balanced from production, but they must not have very tight specs, certainly not mil-spec.

Machine Shop will either need to make an arbor to bolt the flywheel to or use a Viper crank as an arbor. Fortunate for me they had a Viper crank in there at the time and had just balanced it. It was used as the arbor and the flywheel was bolted to it and balanced. ( a very small amount of material was taken off.).

Now, with the crank in balance and the flywheel in balance, the Pressure plate was put on and balanced. This required some places to have material removed and some areas to have material added. While bolted together and all balanced up, the flywheel and pressure plate were marked so that you match them up in the same spots when installing in the car. (In theory it should not be necessary, but why not go the extra mile?)

I believe it was worth doing.

YES

I have them on all my cars (fidanza's on all but 1 and that has a RPS carbon/carbon twin disk (my 95 stealth))

My answer, yes.
I put one on each of the RT/10 and GTS.
The RT/10 was done first because the engine was coming out. It worked out so well we put one in the GTS.
If your engine or trans is coming out for other work anyway, that's the time to do it.
I didn't balance either set, specifically to see if there was any noticeable vibration / change (we sell aluminum flywheels and I have to be able to tell people what needs to be done according to our experience). There was no vibration or change. As Marv said above, the flywheel is pretty well balanced as it is manufactured, but it wouldn't hurt to have the flywheel and plate done as an assembly if there was time.
Regarding any driveability issues, it made no (negative) change that I could tell.

1. YES, in a heartbeat!
2. Slight lope with heavy mods but not objectionable.
3. Hennessey did the installation, so I don't know,
but in 30K miles no issues.

Jerry, the aluminum flywheel is a great addition in helping the 'lopey' V10 spin up faster. It's especially useful for road racers who heel-and-toe downshift often. Driveability at low speeds is like stock. All our customers have been really satisfied with the aluminum flywheel, especially in conjunction with our Dual Kevlar clutch kit.
We have plenty of aluminum flywheels in stock, ready to ship. For pricing, please e-mail me directly at [email protected]. Thanks!

I disagree, but it's still worth the expense.

No low speed problems with the wheel from Roe Racing on my '95. Car runs great!!!!

I'm about to do it, so I hope the results are as good as expected, flywheel and clutch on their way from states at the moment so I'll post when its done probably in a couple of months. I dont plan on balancing them, fingers crossed.
