**Lightened Flywheel**

I have an 87 dodge daytona shelby z. The car needs a clutch.
I am having the flywheel resurfaced. While i have the flywheel
in the machine shop i was thinking about having the flywheel lightened by using a big bore drill bit on the back of the flywheel and having the it rebalanced. Will it cause any drivability problems or throw the motor out of balance??? What about durability??My thinking is take as much weight off of the rotating mass.

Anyone dont this????

as long as the flywheel is balanced after it is lightened it won't throw the engine out of balance. with a lighter flywheel it will make the car easier to stall on takeoff and you may drop rpms easier while climbing hills because the engine has less momentum (inertia). durability shouldn't be affected as long as you don't go crazy with the holes. your engine will rev faster and throttle response will be much better because of this. make sure you check on the price of an aluminum flywheel compared to what the machine shop will charge you for the lightening and balancing of your stock one. it may be closer than you think.

Both of L-body's have lighted flywheels, I like them, not sure how it would do on an heavy car. One shop was able to take 6lbs off 1 wheel and another only got 4lbs off. Makes the engine rev quicker. Both shops cut metal off both sides of the flywheels.

The machine shop can turn it on a lathe to lighten it. I had 5 lbs removed from mine then rebalanced and resurfaced. Total cost was 90.00, a lot cheaper than an aluminum.

The clutch side gets resurfaced only, the weight is removed from the engine side

And YES it is worth it

Dean Stillie's old 2 door shadow had a flywheel that had been cut down on a lathe to lighten it. I dunno how much they took out of it, but it ended up shattering and taking out the trans with it....That's not a good tradeoff if you ask me...I wouldn't go cutting a stock flywheel after that.
