Hey everyone, I originally posted my dyno results from Powerhouse Automotive, in an earlier thread in which my results seemed a bit high at 301 max power and 294ft.lbs torque, for being a Mustang dyno..Although I now believe, that I may know why ? I recalled asking Mike from powerhouse, before taking my car up to them, as to what their results for a bone stock 05 Mustang GT would be ? and he then mentioned their results, are between 260-265 max power..Meanwhile it didn't quite dawn on me, until after I posted my results, that those happen to be the very same stock numbers produced on a Dynojet ? So what I'm hoping to find out is this ! would anyone be able to provide some feedback, as to whether or not a Mustang dyno can be set up to measure both power and torque, similar to that of a Dynojet ? and if so..perhaps this may explain, why my results seem a bit high for a Mustang dyno..My mods during the testing sessions are as follows, pull number 2 in each of the power ranges, were ran before the underdrive pulley install, and then pull number 1 in each range, was ran after the pulley install..However, all pulls were ran with my bamachip's 93 race tune and Steeda 90mm CAI, along with running vehicle load simulation, and standard SAE correction..My air/fuel also ranged between 12.8 and 13.0, through out all the pulls at WOT ..Anyway, I'd be really grateful for any feedback that may be provided, as I'm also including attachments of both the dyno print out sheet, and text data print out as well.. Anyway, thanks once again, for everything in advance

From having my past cars dynoed....it always seems the Mustang dyno reads on the high side. I prefer the DynoJet myself.

if you have experienced mustang dyno's that read on the high side you are in the minority as a majority of all dyno users have found the mustang dyno to read far lower than most dyno jet pulls.

My 07 has pulled an average of 20 to 35hp less on the mustang dyno versus the Dyno jet while tuning my car.

Red- check out this thread on modular fords, should be very helpful for your questions:

A Mustang dyno can load the chassis for more "real world" numbers, but it can also be set to act like Dynojet and give similar numbers.

A Mustang Dyno has a load bearing in it to simulate drag and weight of the car. This load bearing can be turned off and will give you readings that more closely resemble a DynoJet.

Then in that case, I'm really confused because I was assured by Powerhouse, that the load bearing simulation was NOT turned off at anytime, during my dyno testing sessions. As a matter of fact, I was also informed that he never turns it off, unless a customer actually requests it, because of the fact, the majority of his customers require custom tuning.. I don't know if any of this may help or not ? but here's the name and model of his Mustang Dyno... Import Dyne/Model # IMP-DYN.. and here's also the complete list of calibaration parameters that were entered..Car weight, 3650 lbs. w/o driver 13.6 HP at 50 MPH. Temp, 69 degrees. Baro pressure, 30.0.. Humidity, 0.17%.. Elevation, 700 ft. above sea level, using standard SAE correction. If anyone has any further questions ? please don't hesitate to ask. Thanks

For what it's worth, I had my '07 Automatic on a Mustang dyno, stock except for SLP Loudmouths. 251 rwhp, 262 rwtq.
