Dynojet vs Mustang

Basically article states the results comparison between Dynojet and Mustang facilities by running the same car.

According to article when the testing was performed on the Dynojet, the correction factor (based on SAE) was 1.10, which means the observed numbers were multiplied by 1.10 (adding 10 percent ) to get the corrected values while on the Mustang dyno was 0.96 (removing 4 percent). Mustang dyno also involved the actual vehicle weight.

Test Results: 2000 Camaro Z28 6MT

Gear....Dyno.........Torque....HP
4.........Dynojet.....339.7......331.7
4.........Mustang....331.7......315.7
3.........Dynojet.....326.2......322.2
3.........Mustang....313.8.......301.0


The article points also that both the Dynojet and Mustang chassis dynamometers are useful tools that have excellent repeatability. Both dynos measure the correct horsepower and torque for the load that they apply. Both dynos will show losses or gains from modifications.

Their recommend that you pick a dyno for your baseline testing and stick with that dyno type and dyno location (and dyno operator) for subsequent testing.

Always start at the same engine coolant temperatures before each run. Also, use an OBD-II diagnostic scanner to monitor your engine's operating parameters. This will provide the best indication of power improvements or losses For comparing dyno plots to determine losses or gains, don't focus on the peak val_ues but take a visual average by comparing the before and after curves on the same graph.


Now, I'm curious is if Mustang shows the results close (according to them) to a real street results then why in that case say here in Illinois I found 27 dyno facilities with Dynojet while only 7 with Mustang

Dynojet is the defacto industry standard which is what everybody likes to use. The thing I don't like about the Mustang dyno is that it apparently adjusts the load based on the weight of your vehicle? That means its using a different standard for measuring on every car that it hooks up to vs the Dynojet which uses the same standard for everything.

But the main point of a dyno is for tuning anyways. And yeah, as long as you stick to the same type of dyno and preferably even the same exact dyno you should get very consistent results and be able to measure even fairly small modifications.

Is this from that recent article where a magazine tests out 4 or 5 various dyno machines? I think it was SCC.

No, this is a different test. The one your referring to is the one where they used a 350Z .
