Came across this interesting blog.

Blog - The Dyno Dilemma - SAE vs. STD Dyno Numbers

According to this information the Mustang dyno (using SAE only) will always read lower than another brand Dyno using STD (it has the option to use SAE) and that the standard formula to compare a STD dyno sheet to SAE is -4.8%

So my Mustang dyno session last autumn which read 203WHP SAE would have probably read 213 WHP on a Dynojet using STD.

a 400 WHP dynojet reading would read 380 WHP on a Mustang.

I was wondering if any of our more experienced members and resident experts had any disagreements with this information.

It's pretty well known that the Mustang dynos read lower, and it even nicknamed a few "heartbreaker".

However, in reality, it's irrelevant. A dyno is to find a delta, or dial in a tune. It's a tool.

hehe i know its well known, but i have heard many different ideas of by how much. Some have said up to 15%, so when ir ead 4.8% i was curious at to what the forum thinks.

also, i didnt know that dynojet has the option to use SAE but i'm guessing most operators use STD to post higher numbers.
