Pre Whipple Base Dyno Pulls

[7GHellboy]

Hey, take a look at the charts and please provide comments on the results because they seem pretty low for what I was expecting based on the mods and other dyno runs.

I know results depend on the dyno used and ambient conditions but lets take the results as an order of magnitud more than as an end result.

The car is a 2024 Mustang GT (performance pack + active exhaust) with a AXE catback and a K&N Typhoon CAI. 91 oct gas was used.

You'll see 2 charts, one with the hood closed and the other one with the hood open.

Looks like about a 14% - 18% drivetrain loss in HP to give you the RWHP on your dyno sheets, which is to be expected compared to the flywheel HP rating (which is what the manufacturer gives you).

What's with the dip on the first chart

Looks like it pulled spark or closed throttle bodies up top.

really good for 91, you could’ve put boostane in and drove 20-30 miles before your pulls to have max timing, probably would’ve picked up 10-15 or more HP.

Values seem fine to me. First graph looks a bit messy up top. My stock pulls were 376 hp / 335 ft-lbs SAE corrected in Denver.

I would really like to see numbers with the stock intake to compare to the K&N. Hood down, hood up, hood up with no lids. If you ever have the desire to spend another $100 to collect data...

exactly what would be expected. And it shows what I've always expected. Cat Back and cold air look and sound really good, but cars today are at close to maximum efficiency. Those mods just don't add as much today as they did with earlier cars.
