That's just the brand name. It means nothing as far as our cars are concerned.

Correct me if I am wrong....but a "Mustang" dyno has nothing to do with our beloved "Ford Mustangs"

It is just a brandname.....

OK, here is the meaning behind a mustang Dyno. A dynojet measures hp/tq on a given car. The rollers all weigh 2000 lbs. On a mustang dyno, the rollers weigh what ever the car on the dyno weighs. With approximation if the car has never been weighed at a track or on a scale. My car, 87 GT with TFS Track Heat Heads, stage 2 TFS cam, street intake, 30lb inj. 80 mm MAF, 75mm TB, MSD 6AL, shorty headers, 1.6RR, O/R H pipe, 2 chambers, and a flat as hell fuel curve made 268HP/288TQ on a mustang dyno. On a Dynojet, the same car, almost identical conditions, made 305RWHP/345RWTQ on a dynojet. If you run on a mustang dyno, its actually like you tuned your car for the street cause you are trying to move a set of rollers that weighs the same as your car. If you put a honda civic on a mustang dyno and then ran it on a dynojet, the numbers would actually be identical. Because the car weighs closer to the 2000 lb mark that the dynojet rollers weigh. A Powerstroke would have a greater difference between the numbers than even my mustang did between the two dynos, because the truck weighs so much more. You see what I am saying? A car tuned on a dynojet will actually be tuned to run Fatter( richer) on the dyno so it will run a flatter curve on the street because of the weight difference of the actaul car vs. the 2000 lb rollers. But, it still might not be absolutely perfect. Where mine is flat on the street oron the mustang dyno. On the dynojet, it runs way rich. I personally believe in the Mustang Dyno, I have a SCT custom burnt chip from www.trudynosports.com and my car ran AWESOME! The guy really knew what he was doing. I would not have my car tuned any other way. Numbers dont always mean a great running car. I would much rather have a car that is reliable and fully streetable and able to drive to California and back and then hit a strip or two and not worry about whether my motor was going to detonate or throw a rod through the block. Like was said earlier, some people throw down big numbers on a dyno to show how much ***** they have but on the street theey aren't are bad *** because of the timing or the tune of the car. Just my LOOOOOOONG 2 cents hehe.

The Mustang Dyno comes with a program that lists the weights of all the cars and what values need to be entered in. Personally I don't think one is really more accurite or better than the other, just different. The only other thing i have to say is that if Dynojets are so great, why are they coming out with an Eddy Current Dyno (same technology as Mustang)?

I don't think they are great at all. If you want the truth, go to the track. But given that all the machines are calibrated equally, you can go to a Dynojet in California or New York and get the same numbers. With a MD you can do 2 pulls on the same dyno with different operators and get different results. Weight is not the only variable. The MD leaves too much in the hands of the operator. If the guy is good, the results will be. But I don't put much faith in a majority of dyno operators.
