Need help understanding this Dyno graph, it was done on a mustang Dyno from my understanding. The numbers seem pretty low in my opinion and I don't know if there is a way to convert these numbers to whp and rwtq ? Anyone been through this?
I've read that the mustang dyno numbers will be ~12% lower than DynoJet. I saw a video of a guy with a stock Mustang (car not dyno) on both dynos and the numbers were 6-7% higher on the DynoJet. I assume conditions were not the same though.

So a mustang Dyno is underated then? Now I'm curious about my results on w dynojet 🤔
All dynos vary from one another. If you want to feel better about yourself and pay to possibly see higher numbers then try somewhere else. The real benefit is to see a before and after against the same dyno after a mod or tune.

Yeah you're right it was a nice gain I really can't complain. The difference in the drive is what really matters

From what I read I wouldn't say "underrated" I'd say more "accurate" since mustang dynos simulate load similar to when you're driving on the street. If you want to do any comparisons I'd only compare with results from the same type of dyno.
"If you took a typical DynoJet dyno (chassis dyno) and ran a car on it, it would give you a given number based on inertia and the spool-up speed of the drums. If you took that same car and put it on a Mustang Dyno or SuperFlow "load" dyno, you would get a much lower number simply because they are measuring power under different circumstances (under a load)."

Wow that's a great article bro, helped me understand a bit better. I'm just going to keep going to same Dyno after new mods later on. Thanks
The most reliable power measurement comes from the quarter-mile track. There are formulae on the interwebs that will convert trap speed to HP.
Dynos, especially since there multiple types, are really only good for measuring changes you make. Always use the same dyno when measuring changes. And when you run, make sure the operator set's the machine for "standard conditions" since ambient temperature and barometric pressure influence power output.
This is my first time using a Mustang dyno also and confused on what is what. The day of the dyno, my numbers on the screen were as follow:
max hp: 337 hp w/ WCF: 343 hp max tq: 278 tq w/ WCF: 287 tq
This was what was on the screen after my 3rd pull. I got my print out yesterday and I see this. Granted they cut off the graph before redline but I don't think I'll see anymore hp past this point. So Mustang dynos can display calculated numbers or measure wheel numbers on the screen?
I suspect WCF stands for Weather Correction Factor. I'm amused at the engine power number, as if their dyno knows what your driveline loss is. It has to be just an estimate.

Correct, on the WCF abbreviation. So from the OP's graph, are his numbers calculated or the measured wheel numbers, since his says "Engine"?
