atx flywheel

half_twisted · Post by **half_twisted** » Fri Feb 01, 2008 8:03 pm

just a thought so dont flame on me guys.
I was thinking of a way i could reduce rotational weight on the crank to get quicker revs and response. I know guys with mtx trannies do the light weight flywheel thing so im wondering if guys with atx trannies can to.. can this be done?

Don't feel bad, I've often wondered the same exact thing myself... just never had the courage to ask at the risk of sounding like a

No, I agree.... this is a GOOD question to ask.

I have never thought about it, before...... Not for ATX.
But why not ??

I'm not sure if I understand the question correctly, but.... the torque converter bolts directly to the drive plate, there is no flywheel in the atx. Only the MTX with a non modular clutch can use the aftermarket aluminum flywheels.

many people call it a flywheel when really its a flex plate. while technically the wrong term, it gets the point across for most.

And the flex plate itself doesn't have alot of mass, no way to lighten it without sacrificing strength. The only option and not too sure about cost/availability would be a smaller diameter and/or higher stall TC. The older V8 ATX's have lighter internals available, but getting lighter, stronger internals for the 31TH and 41TE is prolly expensive if they even exist.

well I know we could add a light wieght crank pully but that alone wouldnt help reduce the rotational speed. doesnt the atx have a flywheel that the starter turns to start the car?
I hate it when I floore the gas and after letting off the engine stays reved for about 2-3 seconds, talk about gas killer.
would swaping the stock accessory pullies with light weight aluminum pullies make a huge difference.

The part that the starter engages is the flex plate. And said above, the flex plate weighs next to nothing by itself. This plate is sandwiched between the torque converter and the back of the crank. A smaller TC would be the way to go if you could 1) find one and 2) afford it.

why not just get a different torque converter

See above post, There just isn't a ton of aftermarket for these transmissions, and what is there isn't always cheap, particularly when compred to the parts for other trannys

Working on my motor tonight, I thought I'd take a pic to show the drive plate can't be lightened much, weighs around 3lbs as it is anyways. There's not much to it.

Cool, thanks for the pics. That is actually alot stouter than the old big block flex plates, but then the starter ring was on the TC. I'm sure you could punch some holes in it, but the gain wouldn't be worth the troubles of getting it balanced.

True, especially since I have seen the centers ripped out of them in the 2.2 turbo cars (stock). They use the same flex plate design, if not the same part entirely...got to check that...

youre money would be better spent on swapping to a manual

Post by **occasional demons** » Fri Feb 08, 2008 9:43 am

Where's the challenge in that?

Danteneon · Post by **Danteneon** » Fri Feb 08, 2008 11:06 am

I seems that my hunch was correct...Chrysler has used the same flexplate in almost every FWD ever..2.2, 2.5, 2.0, 2.4, 3.0

Part #4446309, MSRP $144.00. I have watched the price go up on this over the years. I remember when it was $75.00

Whoa.

Makes me wonder about those people who have turbo'ed their ATX Neons .....

There is, but it costs a lot of money.

a lot more than a 5spd swap.

As for reducing rotational mass, how much weight would knife-edging the crank take off?

Great question. I don't have an answer, but I'm sure it would be effective..... because weight is being removed where it really counts.

However, I would think it would require getting the entire engine assembly completely rebalanced ..... some rebuilders may end up having to ADD some weight in some other areas to balance it.
So it could end up being a wash ....
