Load based dynos normally read lower than inertia by as much as 10-15%.
I would bet if they hit a Dynojet brand dyno they would have higher numbers. That is why everybody likes them so much.

^ thats what I was led to believe as well.

No man, I wasn't suggesting the numbers are fudged. But what I was saying is, in general, load bearing dynos typically produce about an extra 40 whp than a non load bearing. I just talked with a friend of mine who's a tuner and he told me that there is one model that dynomite makes that is supposedly a "simulated" load bearing dyno. Not sure what that means exactly or if TE even uses that model. Just something I was thinking about.

True because they tuned Joe's tC when he lived up there literally 3-4 times. We wanted higher numbers 1 or 2 times, but where a little heart broken. Their dynos is definitely on the lower reading side if any......

How much would it cost to get this kind of power?

Where the hell do you get your info?

Taken from a Mustang Dyno tuner's site:

Mustang 500 series eddy current load bearing dyno instead of an inertia type dyno like a Dynojet because we want to have the proper tool to accurately build a map for a vehicle's ECU. A load bearing dyno can actually simulate actual real world road conditions such as stop and go traffic, towing, steep hills, cruising etc. It works like a reverse electric motor. Instead of doing work it actually creates resistance or load. It is virtually impossible to properly build a good quality map without providing a consistent supply of load to the vehicle. Combined with our extensive training and knowledge in the industry, we at DTM can provide a tune that is safe, repeatable and power packed while maintaining good fuel economy. We have typically seen gas mileage gains up to 25%.

What is a "Dynojet" Inertia Dyno Tune?
An inertia dyno like a Dynojet works very well for vehicles that see mostly full throttle runs that are mostly seen in racing conditions. Since it only works on inertia (stored energy) you cannot hold(control) a certain RPM on a particular load cell in the vehicle's software. In the real world a vehicle will only see full throttle only 5-10% of the time. That is why most vehicles tuned on an inertia type dyno will typically have spotty driveability (poor throttle response/flat spots) and have poor gas mileage in typical street driving. That is why you will still see companies that own inertia dynos still use the street to build part throttle maps. Street tunes are totally unnecessary when you have a load bearing dyno. It is right the minute it comes off the dyno. Companies who have these inertia dynos know this problem have tried to sell the idea that they can load the dyno by using the air brake feature to create load. What typically happens is inconsistent part throttle maps due to fact they cannot hold high loads for long periods of time.

If a Dynomite simulates load of the street, how can you get MORE power on the street with 'load' versus no load on an inertial dyno, like DynoJet? Makes no sense!

Where the hell, huh? From real tuners who actually tune cars. Not people who copy info from a website and repost it as fact. I'm not talking about mustang dyno's, I'm talking about what I know, in general, namely dynapacks. You ask any tuner if a dynapack's numbers are typically higher than dynojet and see what they tell you. Its real easy to pretend you know everything from pulling up a website and reposting something you just read.

wow that is jaw dropping...i didnt even see it until now but damn...well that just shows that a d17 is just as capable as a k

Agree to disagree and drop it and be happy that people are making the power they are.
