We had a chance today to dyno a customers 2006 Z06. The car was bone stock with 1,500 miles. The first run was done on our Mustang Dyno and the second was done on our Dyno-Jet.

Mustang Dyno numbers were 414RWHP / 390 RWTQ
Dyno-Jet numbers were 453RWHP / 423 RWTQ

Interesting comparison!

Starting with an SAE certified 505 B.H.P. the Mustang dyno shows a 18.02% drivetrain (parasitic) loss, while the Dyno-Jet shows a 10.3% drivetrain loss. (If my math is correct.)

and this one's better yet, 7 points.

I just can't believe the difference in the dynos. That really makes me want to run mine on a dynojet. With K&N filters, and Random Tech high flow cats on a Mustang dyno I turned 343hp/329tq

what a difference in #'s!

Ok, unless im missing something, why is there such a big spread between the dyno's?? Is one of them out of calibration or something?? If the machine is to measure the HP & TQ of a vehicle, shouldnt they be a hell of alot closer than that? Otherwise, which one do you believe is accurate?

cerino2000

The Mustang dyno actually puts a load on whereas the other is an inertia dyno that calculates by how quickly you spun up the wheel. The guy that ran mine (as well as others) said that the mustang reads about 10% less than the dynojet. Considering that, that would put mine at like 377/361 which would be pretty damn nice considering the minor mods. I think it would be fair to mention that mine was done with the hood open which provides cold air too.

cerino2000 is correct, the Mustang Dyno puts a load on the car as if you were actually driving on the street whereas the Dyno-Jet is a "Free-Rolling" Drum. You probably noticed how long it took to make the pull on the Mustang Dyno; on the Dyno-Jet it didn't take nearly that long.

Both Dynos were recently calibrated. On a lower HP vehicle the numbers seem to be much closer.

Hmm. Well, my last pull about 3 years ago I had 587 RWHP and 487 RWTQ on a dynojet. Im about to get it redone in a couple days and it will be on a mustang dyno. I installed a cam about 2 years ago and never had it redynotuned. Plus with my first tune, the person that did it did a crappy job and its running rich. Im curious to see what I get now but I would have rather had a comparison done on the same type of dyno. And yes I did notice how long it took to spool that C6 Z06 up, and when I had mine done, it spooled that wheel up pretty damn fast on the dynojet. Anyway, regardless of the differences of the type of dynos, both dynos are still instruments used to measure the same thing, I think they should be a little closer than what they were, but thats just me.

Could you post the Mustang dyno read out...just would like to compare...this is my C6 with the LPE 366 package dyno'd on a Mustang dyno about 3 weeks ago>>>



Thanks

I don't see the dyno industry coming up with standards in the near future. It would be nice so we could have a baseline depending on the type of dynamometer being used. Both Mustang and Dynojet sell load control and inertia units.

To make a fair assessment you would need to test on similar dynamometers. Dynojet's LC is 224LC and compares to the Mustang dynamometer in question.

SAE does have a new engine dyno standard but nothing worked out for chassis dynos. The new Z06 was one of the first rated motors on this new standard.
