Dyno numbers FULL E85 mustang dyno!!!!

You guys think these numbers are off?? I know it would have read higher on a dynojet.

Your thoughts?

2020 M2C tuned by Wedge Performance

506whp / 590wtq

2019 M2C tuned by F80Paul

Can you post the actual dyno graphs?

What gear were the dyno pulls made in? 4th or 5th?

Did they make sure the car was in "Roller Mode"? This IS A MUST, otherwise you get lower numbers due to the car locking the rear differential and limiting power on the roller.

It's hard to say without a baseline dyno before mods. If your car baseline dyno was at 380-390whp (which is what M2C's usually get on a Mustang dyno), then I'd say that's a fairly healthy gain.

Still, I would think on Stage 2 E85 these cars would make around 550whp even on a Mustang dyno.

It's also curious that the M3 made as much power as the M2C's but only on E30, although it's torque was down by a lot.

For reference, my tuner said my car on Stage 2 PUMP GAS (92 oct) makes around 520whp, but their dyno is like a DynoJet.

Yeah all 3 cars were on "roller mode" and ran on 4th gear. And yes i was expecting something like 550/530-540.
Thanks for your input 🙌🏻

It should be done in 5th gear which is the 1:1 gear ratio for this car and yields a bit more power although it's not a dramatic increase (5-10whp difference).

The reason why graphs are important is because they paint a clear picture of how the car is running. Peak numbers aren't enough to know if the car is running properly. You want to make sure you have healthy power and torque curves. If you don't have the graphs, I'd call the place and obtain them.

We can't really help without baseline figures and more info about the custom maps (how aggressive boost and timing )

Seems right on par to me. The difference between E30 and E85 isn't that drastic so the difference will only about 50hp max.
