Chassis Dyno opinions? Options

[RJMII]

My point and click adventures today landed me on a chassis dyno on eBay.

I've been contemplating the idea that there aren't any chassis dynos within 160 miles of where I am sitting; and that there *might* be enough people in the area that are potential customers. Oh, and if I go for a portable system that could be loaded up in a small trailer, or at the front of the trailer in front of my 914... (pipe dream here, back to the dyno)

What say ye? quality of dyno? company's reputation? Accuracy of dyno? company website http://www.dynocom.net/index.asp

Other dyno options (portable chassis)?

I ran a dyno tuning shop for five years using a Dynocom (same company as those pods) inertia dyno. For starters, the dynocom units are very high quality units, and the software interface is hands down better than anything that mustang, dynojet, or dynomite (land-and sea) have out there. that being said. Dynojets are notorious for reading high numbers, sometimes 10% higher than a comparable unit from a different manufacturer. For that very reason, dynocom has a feature in their software to correct for dynojet numbers. So the video above is right on target comparing the two systems.

Either way comparing results from two different days is comparing apples to oranges, due to atmospheric variatons, let alone 2 different systems. And although the software supposedly correects for these variations a small difference will almost always be noted. (1-5%). If you are looking for a dyno for personal use, measuring hp and torque, you would save lots of cash by buying a roller style inertia dyno. The pods are a good deal if you want to do steady state tuning and measure HP. but in my opinion are a bit pricey for personal use.

Either way, nothing beats having your own dyno. And if you are in the market, the dyno I ran is in storage and for sale.
