Mustang Dynamometer? Video
Anyone ever heard of this type of dyno?

I had the pleasure/displeasure of some free runs on one this weekend. These guys were going to charge 55$ for 3 runs, and I've been dying to get on one so I offered to be first in line at the car show they were setting up shop at.
They said 5 more mins about 5 times and about 2hrs after starting to assemble the dyno they were ready to go. I put the car up there, they strapped me down, and they told me what to do. First pull they told me I had 472ft/lbs torque. I proceeded to tell them they were crazy and it was impossible. What the hell was the dyno smokin? Anyway they said I have 205 rwhp and 427 lbs torque. I seriously laughed in their face. I proceeded to tell them factory ratings were 305 lbs and I would be looking for somewhere around 275 lbs or more. I would have also been extremely happy with 250rwhp(tell me if I'm crazy). So they fiddle with it over and over, and I do run after run. About 7-8 runs into it they said they wouldn't charge me since this is new equipment and they didn't know what they were doin.
So this guy proceeds to tell me that the dyno figures in the factory weight, drag coefficient, and the supposed hp needed to travel 55mph into some mathematical calculation to determine a true hp rating. I continued to tell him there is no way in hell that my car has only 205hp, not to mention 472lbs torque.
They keep messin with it and they get the numbers more inline. 211rwhp and 250lbs torque. Am I crazy or is this stupid low?
Does anyone know what this would be in comparisson to a dynojet? I told them factory rwhp should be 225-230 and they need to take out those "simulations". They said they did and came up with the same numbers but I'm not buying it.
Anyway they said I could do a 1/4 on the dyno. I've never seen this before so I give it a shot. I feather out at 3000rpm and run it hard, catch 2nd, then 3rd on the dyno(they had me strapped down pretty damn good). I finish the 1/4 in 14.4x
I did two more runs like that - on the dyno - one was 14.149 and the better:
60ft 2.030 - 32.628
330ft 5.820 - 51.588
660ft 9.019 - 78.048
1000 11.776 - 89.116
1/4 14.129 - 96.573
Am I to believe a 3600lb car will do the quarter in 14.1 with 205-211rwhp? What gives, I was pretty p'od until the they said it would be free.
I have a video - my friend didn't hit record in time and what you see is 2nd gear and the shift to 3rd, then to the end of the run. I never went into 4th on the 3rd(best) run.

So what am I supposed to think about this dyno, numbers, and could I expect to see 250rwhp? I was ok with the 14.1 1/4 but I would love to see 13.9.
