Man, I hate to bring this up again, but...

[Jerriko]

A thread a couple weeks back mentioned that some vendor carried an aftermarket aluminum flywheel for a 3800 series 2. Does anyone remember who sold it? I checked the various vendors on this site (TByrne, Thunder Racing, LM Performance, etc) but I couldn't find a listing for this flywheel. Seeing how no one makes an aftermarket one for the 3.4L, some people may find it interesting that the 3800 flywheel will bolt right up to the 3.4L V6 (without any problems). The only difference between the Centerforce dual friction kits for the 3.4L and the 3800 is that the 3800 kit has a pressure plate that applies more holddown force than the 3.4L. The diameter of the disc and pressure plate is the same as is the spline count of the disc(26). So for people such as Tiago who has complained about the disc slipping under heavy load, this maybe an answer. But please don't take this info as gold yet, I need to find the 3800 flywheel to get it and test it out.
Thanks,
Jim

You might want to edit your post to say "might" or "should", not "will".

The clutches are not interchangeable and I doubt the flywheels are.

I know, I tried. [img]smile.gif[/img]

Back in the spring of 2000 when we performed my engine rebuild I bought a Centerforce Dual Friction for the 3.4. (At that time there were no aftermarket clutches for the 3.8 and knowing how V6's usually get treated by the aftermarket companies, I wasn't holding my breath.)

The diameter and everything was the same but the dowels didn't line up--we could not get it to work. So I sold that clutch cheap to some guy named TealV6 aka Steve on camaroz28.com.

Just wondering, why not just buy a remanufactured cast iron 3.4 flywheel? Why is aluminum or steel that big a deal? So there's one modification you can't do... do every one in the book but that.

The discs are the same size in diameter (overall and input shaft) and have the same spline count (26). The bolt patterns for the pressure plate were also the same. And yes, I am considering the cast iron but I just don't want to worry about cracking and warping the cast iron one. I do think its a little ironic since I did want a heavier flywheel but I am looking into this possibility with the aluminum one. :rolleyes:
But anyways, that's why I'm glad you guys are here to bounce ideas off of and get feedback.
Thanks,

That's funny, they should know better. If they were interchangeable then they wouldn't have bothered making two different 3.8/3.4 clutches.

The bolt patterns are NOT the same. This is why I was forced to sell mine to TealV6 rather than just return it to the shop I bought it from. The bolt holes were completely different so we had to drill new holes just to line it up. Then when we discovered that it wouldn't work I had a $400 clutch with holes drilled in it that I couldn't return. So I sold it dirt cheap online.

What about getting the flywheel for the 3.8L V6, bolting it to the crank of a 3.4L V6 and then using a 3.8L V6 clutch set to finish it off. That should work, right?

That's what I am thinking. Since the spline for the 3.4L set is the same as the spline for the 3800, it should work fine.

If you find out that the 3.8L V6 flywheel will DEFINITELY bolt up to the 3.4L V6 crank, please let me know. That will open up some more doors for me.

I am waiting to hear back from Spec right now.

It was SSMS who had Spec do the flywheel for Ironman24. His has been on for a while now.

Ironman24 has a 3.8. They are asking if a 3.8 flywheel will bolt onto a 3.4 crank.

[Tiago]

I am 90% sure teh 3.4 crank has 6 bolts to hold the flywheel while the 3.8s have 8. Or something like that I remember a difference in the bolts.

[BillyCobin]

The 3.8 has 8 bolts for sure.

I have great news. I have been talking with David Norton at spec and he is willing to drill an aluminum 3800 flywheel with the 6 bolt pattern for the 3.4L crankshaft. So anyone with a 3.4L who wants an aluminum flywheel would be able to get one. As it stands right now, I will be getting the customized flywheel and 3800 clutch kit to use on my 3.4L. The bolt pattern is different between the 3800 and 3.4L pressure plates as is the clamping pressure. The clamping pressure for the 3800 is stronger than the 3.4L which will help to reduce any slippage. The spline count and inner diameter of the disc are the same so that will not be a problem. Best case scenario is that since he is willing to drill the 6 bolt pattern that he also drill the 3.4L pressure plate bolt pattern giving us access to an aluminum flywheel for the 60* V6s.
