Theyre not out yet. They are still in the testing phase.

My front mount is cracked. If this has already been discussed, I apologize, but what causes these mounts to go bad and what are the signs to look for to let you know that these mounts have gone bad?
I get VERY bad vibrations under the hood at acceleration, mainly 1st, 2nd, sometimes third.

Pics of the Excelerate Field Test Mounts. Sorry it took so a bit, not a pro picture taker and then loading and editing . . anyway, here they are. In a separate thread I'll post the Innovative mounts as we'll be referencing them from time to time.

That front mount is a much better design. Instead of pulling up on the mount and applying pressure on one (weak) point when the motor torques it can now absorb much more pressure. What durometer are they?

Pics of the Innovative mount for reference only.
1st & 2nd Generation Design. Note: There were some subtle differences in the bushing composition and the inner housing of the front and rear mounts, but otherwise they looked the same.

Now Excelerate did say that the side mount is not as thick as the final production product will be.
That said, if you look at the Innovative 3rd gen mounts that I'm running now you'll see why I still think that was the right design approach. It allows for MUCH more surface area to absorb the stress which will help the bushings last much longer. And more importantly for the auto tranny folks . . . it'll dissipate vibrations better. Anyway, I hope the new manufacturer will reconsider this as I'm not confident their larger bushings will be enough.

Fair enough. Ive never been a fan of the way the front mount was initially designed from Honda. Ive always liked the design of the 6MT rear mount, but the way the motor pulls on the front mount seems to put excessive stress on it.
And I do agree the welds look a bit lackluster, for lack of a better word.
Have you been able to install them yet?

When I went in to replace my Innovative mounts, the owner told me in person that if you have the 60A bushings, 99.9% you WILL have to replace sooner or later. I went with the 90A ones and I've never been back there since. Vibrations aren't as bad as it was on the 60A ones, that's for sure.

As for installing them . . sometime this week . . . between running kids to soccer games and the dam taxes have been kicking my butt . . mostly because I've started up my own business due to a job loss last year. And there's still nothing out there after 14 months.

As a reference to the Innovative mount vibration problem, here is a short video on how bad it was. Note, the vibration was reduced by about 90% when removed Innovative rear mount and installed a rear OEM. I still have Innovative on the side and front.
I used a Gatorade G2 bottle and partially filled it so you can note only hear the keys and dash vibrating, but you can see the liquid percolate like crazy.

Actually, this is with the 1st gen Innovative mounts. It started when the rear was installed. With an OEM rear mount and Innovative front and side mounts there is still some vibration, but not that bad and what one would expect of a performance mounts.

If you want an engineer's input let me know. I have a degree in Mechanical Engineering Technology and work with an engineer who designs numerous parts, some have been for a car that competed for the Ridler and received second place in 2009. Obviously I would need a set in hand to do a proper analysis. So far the design seems to be going in a good direction. I know many people are in desperate need of a good set of motor mounts myself included.

Maybe its the sleep deprivation talking, but wouldnt the bracket on the motor still hit the header?

Honestly, I've got some cheap Ebay headers on there (2nd set) that work just fine with no clearance issues. 1st set did too - had more issues with clearance on the front crossmember than on the rear mount. That rear mount kind of teardrops over...I think if you pushed the bulk of the firewall side toward the drivers side of the car, and used an arm to connect it to the motor, you could create a more rigid mount with full rear bank clearance (and it would probably work on the auto car just fine too).
We were going to use the auto mount from the TL when we swapped in the motor from it, but it seems like it just flat out didnt work with the shift linkage or something funky....been too long...likewise on the lack of sleep.

Just finished my taxes . . . finally. What a PITA !!
Anyway, it's been one PITA after another. I had just ordered some new struts and they came in damaged . . . and . . . early this evening while picking up one of the boys from soccer my driver side muffler broke at the flange and was banging all around! I've not seen that sort of thing in years . . . my car is such a POS right now . . . anyway, now that the taxes are done I'll be working on the mounts Thursday . . so cross your fingers that my luck has changed.

Excellent idea on using the Gatorade bottle as a seismograph . It communicated to the viewer very well as to how much vibration is present.
Looking forward to seeing a comparison video once the prototypes are installed. You didn't drink our "seismograph machine" did you ?

Two notes:
1. That side mount is just for fitment purposes. It's only to get an idea of how to make the final side mount. The front and rear mounts should be on point so there shouldn't be much change in those unless we find a fault.
2. The mounts should come to market for around $300.

Yes I really tried to focus on functionality and reasonable pricing when making these mounts. There are, of course, mounts out there that are more aesthetically pleasing but they cost more and they don't always do the job. Hopefully these can do what we want. So far the 3rd gen TL mounts have been doing well.

I dont give a shit what they look like, if they perform better then our current options Im happy.
What durometer are these Josh? And just to verify, we are to use the stock tranny mounts?

Well motor mount fans . . . the good news is we (I had another TL buddy - NAiL05 - helping out and he's a certified mechanic) installed the mounts. The side mount fit fine . . no problems with hole alignment like we had with the first side mount from Innovative. The not so good news is that we encountered a setback and uninstalled them. The initial issues is that the front and rear mounts are a bit too tall and we didn't feel comfortable starting it up with the motor sitting up. The one good thing that may come out of this is Excelerate is calling the vendor and will request a conference call with him and I. I hope that happens so I can present the vertical (up&down) piston design which I still think is the best approach. NAiL05 got to take an up close look at the 3rd gen Innovative mount design and started to agree that it's probably the best approach as well. (see pics in post #9 to see what the 3rd gen design looks like.) As soon as I hear back from Excelerate on the call request and have more to share I'll post an update right away.
Other than that the bushings are bigger and much more solid and should hold up better than the Innovative mounts. And regardless of design I was really looking forward to testing them out.
