New drive-shaft dynamometer. Need your help. I'm not sure this is the right place for this. But, here goes...
I have just developed a new drive-shaft torque sensor/dynamometer.
It works with the Innovate Motorsports LogWorks software. And the LC-1 and the rest of their MTS devices. It is a real strain-gage based torsional force sensor. No accelerometers, timers, GPS, etc.
It's just the box and the coil on the tail-shaft. The rest is just a display stand
It is similar to the Land-and-Sea "On-board Dynamometer" see: http://www.land-and-sea.com/rotary-s...shaft-dyno.htm
Here it is, installed in my 2002 2500HD 4x4
So far, testing has gone better than expected. Even with the big 32-spline 1410 yoke on my HD, I can easily resolve less than +/- 1lb-ft of torque ( out of a full scale of +/- 4500 lb-ft ) and +/- 1hp. Although, the weather has put a temporary hold on further testing.
What I am looking for is the info that I need to make installation kits for the various GM RWD applications. Specifically, the slip-yoke dimensions and the tail-shaft housing dimensions that I need to mount the field coil.
I am trying to get this out to the public for less than $1500.00 ( vs. the $5000-$7000 that Land and Sea wants ).
Any help, dimensions-wise, is appreciated
Thanks, all

Ok. I am FINALLY allowed to talk again
AEM ( who took over the Dyno project from me ) has released their version of the driveshaft dyno kit!
http://www.stangtv.com/news/aems-dyn...bers-on-the-go
It came out pretty damned cool, if I must say so, myself

Just looked into it...
Called aem
No price set yet, not available yet...
To be introduced at SEMA....
I can't wait...
I was ready to buy it when I read the article this morning...

I just finished helping them set up the SEMA display for it. It's pretty neat. It has a mock-up transmission tail section with a torque-arm handle on it that you can grab and see how much torque you can pull. This HAS to be a disaster in the making. But, should be fun, in the meantime
I know the pricing is supposed to be about $1100 for the standard kit ( stock yoke ) and around $1500 for the kit with the upgraded Chrome-Moly steel yoke.
More as it comes in...

Did you ever get it done? What ever happened to this? cant find it anywhere. AEM does not list it.

Dr. Mike was last here in late 2020.
The AEM link provided goes to the AEM site but it's a "page not found".
So it looks like it didn't go anywhere
Edit- You lucked out!

This product was, largely, a victim of bad timing. Just as it was ready, most vehicle lines, in its target market ( Camaros, Mustangs, Challengers, et al. ), switched from yoke drive-shafts to guibo ( flex coupler ) types.
Also, it came out before the X-Series gauges were available. So, the only way to use it was with an AEM data logger, or ECU. If you get an AEM 30-0312 X-series AEMNet gauge, it will, actually, display HP and Torque from a DynoShaft, even though it is not documented. But, there was nothing, at the time.
The truck market was not sufficient to support the product line.
It IS possible to instrument an aluminum "Prothane Six-Shooter" type guibo coupler, in a similar fashion. I never got around to making one, like that.
But, I have, just recently, finished a project that would lend itself to a Dyno-Coupler. Specifically, an OBD2 interface for the AEM x-series widebands, that works with all OBD2 vehicles ( including non-CAN based ).
It could, pretty easily, provide an interface to HPTUNERS, EFILIVE or the AEMData loggers, for a dyno sensor.
On rare occasion, DynoShaft kits show up on eBay.
Maybe I should do a KickStarter, or something, to build a new line of Guibo type dyno sensors
