The dyno was a 2WD Powerdyne Mustang Dyno. Pulled the TC motor and put it on Dyno mode using the Predator. Is this accurate?
Temperature was about 38-45F degrees inside.
1st run was 375HP/387TQ
2nd run was 376HP/390TQ

Here is the graph for the 3rd run:

Numbers are a little high I think... Different Dynos show different numbers.... This can be a good baseline for you so that you can do some more mods and hit this Dyno again...

Are these SAE numbers ? I remember I put down 377 AWHP on the same Dyno , but Corrected SAE Were 361 AWHP , conditions were similar as yours , around 40* .

He only has a CAI, Mopar exhaust, and a tune.... No cam in there from what I see on his sig.

Can somebody correct the numbers for me?
Why is my chart jagged looking?
4th gear pull BTW.

Mods are on my sig.
I was looking at the same thing... Maybe its a dyno / seismograph. :D Was there an earthquake in progress too? :D :D

Ask the Shop to provide it for you , he should be able with no issue . But I just notice the pulls were done in 4rth gear ?? Well my numbers were much lower in 4rth Gear @ 349Awhp , either a extremely happy Dyno , or you have a Beast :)

I am surprised the dyno guy didnt tell him why the curve was so jagged. If thats not a corrected copy he should of got 1 from him. I sent him a copy of my dyno run to show him how a good graft should look.

I'm pretty sure the numbers are fine. You have a lot of mods, but the only power mods you have are intake, exhaust and tune. I did 361 on a dynomite bone stock.

The jaggies are because the dyno operator didn't smoothen it out. Nothin to worry about.

My past experience with Mustang Dyno's is that it was over 10% lower than a dynojet... but it is all in the setup of the dynos.


Dyno numbers from different sources on different days are not to be compared. What matters is that you have a baseline on this dyno. Do some more mods and go back to that dyno and you'll see gains. Go to a dynojet right now with nothing changed and your numbers will go up. That's just how it is.

My 2 cents: 12.5 A/F is too lean IMO and from experience. Usually mid to high 11's are the target. This also allows easier transition with weather changes and/or poor fuel which can both happen from time to time.

As for a mustang dyno vs a dyno jet
I had my old 91' 5.0L dyno'd on both only two days apart and the Mustang dyno it made 241 whp vs 289 whp on the dyno jet do it's quite a difference I found anyway

I would say this is a good baseline as this Dyno is definitely a high reading Mustang Dyno , and Like I said before I've seen at least 5-6 JEEPS from CAM/HEADERS - INTAKE / TUNE average 341-361awhp On our local Mustang Dyno and all are SAE Corrected numbers . Like Matt said the reading are much lower then Dyno jet .
