J32 clutches and flywheels

[DSmith]

This is Danny from Spec. I have been doing some research on clutches and flywheels and wanted to get some info from you guys if I could. We already offer a single mass aluminum flywheel and a heavy duty non self adjusting clutch for the 07-08 TL Type S. We are currently working on the older J32 flywheel and clutch already, but it has been brought to my attention that some of the automatic cars people are using need to have a crank trigger on the flywheel. I need to know what cars have this trigger so we can add it to our lineup for the guys doing this type of swap. With that being said, if anybody has an old flexplate that has this trigger and wanted to let us borrow it, I am sure I can help you out with a good price on the equipment.
Also, I would like to share the info I have came up with and let you guys confirm, correct, or add to the info I have. If there are any more applications, please feel free to hit me up. We want to do what we can to provide the parts you need for these setups as well as offer the support you need. Anyway, here is what I found:

03-09 Accord and 04-06 use the same flywheel and clutch
07-08 TL Type-S uses a different setup all together
2010 TL 6 speed is a whole different animal than either one

The manual 2003 acura cl type s is the only flywheel that uses the secondary crank angle trigger.

Awesome! Thanks for the info! Does all of my other info seem to be correct?

Ok this may be a bit off topic but I have seen a lot of complaints and recommendations not to use a single mass flywheel. They say it throws the rotating assembly out of balance and basically destroys ur expected engine life. Now is this true/fact based? Or is a single mass flywheel much like the CTR N1 pulley for the bseries and it needs a balanced rotating assembly to be truly efficient?

If you were to switch to a single mass flywheel then I would suggest getting the whole rotating assembly balanced together. It is a much bigger change than stock vs ctr n1 pulley.

When you actually pick up a whole flywheel/clutch assembly you will understand. I think it weighs 40 plus pounds. Look at the crank pulley, maybe 20 ish pounds.

Pretend you where designed to bench this kind of weight. the crank being your bar the latter and weak arm and the former on your strong. And then for the hell of it you change your strong arm load and push the bar up as normal. the erratic difference in speed from your strong arm pushing the significantly less weight will be what your cranks does. Remember the thing does rotate but it is the sum of linear vectors transferred into rotational force.

Unless you have/want to spend the funds to send your motor out to a good motor shop for large power gains just use your dual mass flywheel. Use lighter wheels to make up for flywheel shortcomings.

lighter and smaller or both.

I just got finished glancing over the SpecClutch website but wasn't able to find any info on your Aluminum flywheel for J-series applications. Can you link me please or provide more details?
