Dyno Question
Im going to get my car dynoed, and I heard the Mustang dyno gives you lower rwhp numbers as suppose to a dynojet. So my question is which dyno should I get dynoed at a Mustang dyno or a Dynojet?

Depends if you want actual car under load numbers or not. Most want the higher number for self gratification re ***** size. I prefer the Mustang dyno myself. As an example on a dynojet stock I would make 440ish but on a Mustang dyno I would make 395ish. Now you see why people like a Dynojet.

All dynos are loaded, even dyno jets. Software, tuners, settings, weather all have an effect. Dynojet is considered by most to be the industry standard.
The rwhp # is not important, the power curve and the trap speed tells the real story.
You should not even care what the dyno type is. Find the best tuner you can and go from there.

I don't pay any attention to dynosheet numbers. Have no idea what my car puts down or will put down when this build is over. There can be huge variations between machines and operators. I just want to know that the car is producing more safe useable power post than pre-dynotune. The skill, knowledge, and integrity of the tuner is more important than machine type.

All dyno's are NOT loaded, that is incorrect information.
I've owned by dyno's, started with a 2wd Dynojet which was just about worthless. I sold it and own an Mustang Dyno, AWD500SE now. I've had it for about 5 years and don't think there is a better tuning tool on the market.
There is on good thing about a Dynojet, the numbers can not be manipulated. A Mustang Dyno however is easily manipulated to read higher or lower numbers. Unfortunately that's left a lot of shops messing with their dyno's and making them read high, mostly from complaints from customers who want to see HUGE numbers like a Dynojet spits out.
Our Mustang Dyno had my Mustang at about 239 whp stock, 4.6 Shelby. After the Whipple 550 install it made about 395 whp. It also ran 12.003 at 120.66 mph.
I own a Mitsubishi Evolution, it makes 700 whp on our dyno and had run a best of 9.0 at 159.6 mph, in street trim with slicks.
Forget the numbers for the most part, but keep the results and use the same dyno after you've made changes so you can see if you've gained or lost power.
