Broken Flywheel, please help!!!!
Working on a 2000 Corvette, sitting still in park, reved the motor to about 3500 rpms. Had the AutoTap hooked up. Anyway the flywheel blew all of the teeth off, not too much damaged so far. I still need to tear it all down. I'm wondering is this a job I should pay the local shop $400.00 to do or should I do it myself.? And what's the top of the line flywheel? Looking for 900 hp to the wheels..... How much$$$$

I agree, come on, tell the truth, how did it really happen???
btw, if someone put an aluminum flywheel on your car, the starter teeth is commonly known as a ring gear. The ring gear on any flywheel aluminum or cast iron, is heated, and the flywheel is frozen.
The ring gear expands, and the flywheel contracts.
When the two are mated, when they cool/warm up to room temp together, it is a negative tolerance fit, and the ring gear becomes part of the flywheel.
With a cast iron flywheel, the two pieces rust together, and become one.
I guess it's possible that a ring gear could have gotten fractured, and come off, since most of them are made of mild steel, but mild steel doesn't fracture unless it's impinged upon by some force of impact.
why didn't it come apart when you were driving??
certainly you were shifting above 3500 RPM prior to that.

Wow I've never heard of that happening before. That really stinks, If your good at working on cars... then you shouldn't have a problem with the new Install. I know there are a bunch of flywheels out there, but Fidanza has worked for me with no problems. If Fidanza can handle my cars power with no problems, I back them all the way. I hope this works out for you. ~CHRiS~

I just installed a new 408, DTE rear-end and a Rossler tranny. The torque tube and the flywheel are the only stock parts. The car was still sitting on a trailor when this happened. I had the car idling and gave it a little rev, no more then 3500 rpms/ As for me driving the car, I have only put 1 mile on it. There is a running problem that no one has any idea what to do. The car idles just fine, but as soon as you put it in gear, the car stalls. It's killing me that I can't figure it out....
The $400.00 I said before was only for te labor, the flywheel the shop has is a TCI. It's $200.00..

I'm having my balancer done next week. $300 was the quote. From what I've found on the internet/forums, you have to remove half the dang front end. I aint into that anymore. I'm going with the underdrive set up. Then it's a new rear end.. and another $600 labor. I don't care.. I just can't bring myself to crawling under a car anymore. Too many years of it.

What in the H*ll would the converter or bolts have to do with blowing the ring gear off a flywheel bolted to the engine?
Last time I looked there was a torque tube in between the 2.
Besides the ring gear is welded to the flywheel, so did you forget to release the key from the start position?
I guess the starter is toast too!

Let me get a couple things straight.
1 this car is an auto, and you need a new flexplate, not flywheel right?
2.If so, the stock felxplates are pretty weak in general, how it blew off all the teeth is beyond me, but ok.
3. Any SFI approved flexplate should work, TCI is what i have used in the past and worked great. Price is about 200 bux.

I actually drove the car right after I retorqued the heads. The car ran fine for a few miles then we noticed a slight miss. We went back to the shop let the car cool and checked the plugs. I realized that the TR8 pluge I have for the big nitrous were in, so we put new TR6's in and went to crank the car up. There was still a slight miss, but for some reason to put the car into gear I had to hold the brake while giving it gas to keep the car running. Noone has any idea why the car stalls. It will start right up, idle for about 20 sec. then stall, or If I go to put it into gear it's like you turn the key off. It is an auto. I had the tune checked, it was fine. I was still on the trailor with AutoTap hooked up and I gave it a rev, to recork the readouts when the teeth came off. The whole row came off. Any ideas???? Anyone???

If the engine stalls it could be a VATS problem but since it dies when you put it in gear I think it may be a column lock problem.
