In doing research preparing to do the test/review on the 3" Gibson single exhaust, I have changed my opinions on dyno testing. I had noticed that most people were using the Dynojet system over the Mustang dyno, so I figured that is how I wanted to go. After really getting into it, and learning all I could, I now am of the opinion that using the Dynojet system is using old technology. The Dynojet, to put it simply basically uses a inertia flywheel that you turn with the power wheels of your vehicle. Results can vary widely, with different throttle responses once you have the flywheel turning. The Mustang uses an electrical type brake on its system called eddy current. (which Dynojet is now putting on their new machines) With the Mustang system, there are many more tests you can preform, such as simulating towing, simulating hauling a load in bed, "real world" atmosphere such as wind drag. It also allows you to make tests at partial throttle, and constant speeds. Can perform power curve tests under controlled acceleration rates for better data resolution. It will give you 0-60 times, estimated 1/8 mile and 1/4 mile times.
The Dynojet will always give higher numbers, but is that what we really want? Myself, I want precise, accurate numbers. The mustang will also be much more accurate so far as seeing differences between "base line" stock runs, and follow up runs after mods are made.
I have decided to use the Mustang system for my upcoming test/review on the Gibson exhaust. I have a speed shop that is opening a second shop in my area. I talked to the owner, and he has sold his Dynojet from his original shop, and has bought 2 of the newest version Mustangs for his shops. In his opinion, there is no comparison between the 2 units. In fact, he said he could have bought the new Dynojet unit for $24,000.00 less!
The numbers I show will probably be less then those of people using the dynojet, but they will also more accurately show the differences the mods make on our trucks.
