A truly Mobile Chassis dyno like no other Check out this dyno where it was brought right to someones house for dyno testing.

Here's the link to the manufacturer's website:
http://www.dynapack.com/dynapack.html
They were at PRI in Orlando. A long haul from New Zealand, but worth the trip, or so they said. The demos on a modded BMW M3 were impressive. I think they might have borrowed the dyno from the source maldo showed.
The dyno has been around a while, but is just starting to catch on here. It isn't cheap, compared to a Dynojet, but it has many obvious (and some not so obvious) advantages. With almost no inertia, you can step off in 5th gear from an idle and program almost any acceleration rate. Step tests are also easy, as is part-throttle operation for driveablility tuning.
Yep, with a lift gate or a very husky "roadie", dyno service in you driveway is practical. We were most impressed. Oh, be careful if you go drinking with "Kiwis".

There's an article about this type of dyno written by David Vizard.
The article states that:
The load brake dyno eliminates the effects of tire rolling resistance, tire pressure,
tire expansion, tire slip, and tie-down tensioning.

other chassis dyno.
15 points less on both HP/TQ at their respective RPM.

The dynopack really makes sense.
I really like the idea of eliminating the tire interface and slippage. Cars do "behave" very well on the Dynopack. this machine is perfect for steady speed testing.
On the other hand, I actually like the capability to doing an inertia runs on rolls. I can watch the rate of acceleration on my Dynojet and tell if we've picked up power. It doesn't get any more straight forward than this.
One limitation with the Dynopack, cars with narrowed rear axles will require long extensions to reach the axle flange from the dyno "box".
I expect you must check the flange for runout at the lugs.
One way you crawl under and strap it down, the other you take the wheels off.

But the difference is it is highly accurate.

I would like to say I like seeing threads like this. I spent years trying all types of dynos and the dynapack is what I ended up buying. Yes, it is not cheap, our model 4000 was around the range of 80Kplus. So I can see why most dyno shops go with other routes....But what you get with this unit is worth its weight and price. Not only can I build timing tables from scratch, I can tune a full VE table for an SD car in one day. Ask anyone that does their own SD tuning on the street, and they will kill to do that. I can lock in on any RPM, hold it all day long, ect. The next best thing is figuring out how I can arrive at the timing table I do. I can meassure the TQ off the drivetrain in real time, and with my scanner add or subtract timing and see what makes mroe power and when power stops. These types of tools can put any tune into the next world. The result is a car that is perfect, or just near that. The best part is because I can load the car down every RPM and every MAP value, I can now simulate the engine at that RPM doing the most work. This means that when the customer drives away, it wont matter what they do, what tire they use, they will never have a car that is not finished. Have you ever had a tune and said, its nice, but it still pings in 5th and 6th gear? You wont anymore. I know, sounds like a sales pitch....but the dyno speaks for itself. If you ever get a chance to use one, do it.
