Stock 2021 Mustang GT A10 DYNO

[Zach@Granger]

We took our first 2021 Mustang GT A10 and put it on a Superflow Dyno. The speed limiter kicks in in 7th gear so we ran it in 6th. The Superflow Dyno isn't the most generous in regards to number.

We've got some plans for this Mustang that should boost the power a little bit, while retaining factory warranty. We'll have the update next week.

The SuperFlow Dyno's are notorious for reading a little low as well.

Look at the dyno that AM did when they got their A10 GT. It was on 87oct and only made a few more than this one did.

What's with the massive drop at 6800 rpm? Wasn't it supposed to deliver its maximum power at 7000?

These numbers should be around 700.
These numbers have me very worried.
Wait, sorry, I misread the thread title. This is Dyno from a stock car. Whew. Okay, carry on.

Why would the factory fill 87 when at least 91 is required?

I think they just let off a little early on that pull.

Because 91 isnt required. Least 87 is required, 91+ is recommended.

The SuperFlow Dyno's are notorious for reading a little low as well.

But dynoing in 6th gear is going to inflate your numbers slightly, so that should be a wash with the lower reading dyno.
