Dyno run today. 325HP seems awful low
I haven't received the graph yet and I didn't see the torque number at the dyno. 2 pulls came up at 325HP on a dyno dynamics which seems really low for a stock '13 GT.
I *think* the pulls were done in 4th. With 3.73 gears is that a reasonable peak? I'm reading that it should have been done in 5th.
I'll post the graph when I get it. I'm just kinda bummed and wanted to get some feedback.

i own a dyno dynamics, if the dyno was not on "comparison mode" reading "flywheel hp", then your number seems correct. keep in mind dyno jet (industry standard number) reads 20% higher than a dyno dynamics

Yep...I think you're right...fifth gear is 1:1 on the manual gear box. Also...I think atmospheric conditions were not in your favor....which would also lower your peak numbers.
I had my truck dyno'd this past Wednesday. The guy has one on a trailer and does it outdoors....same temp and humidity as you describe. He kept my hood down and got my numbers on the third pull....the runs were back to back to back so I was thoroughly heat soaked. Anyway, I know I was down probably 20-30 hp and torque maybe 50-100 ft/lbs ???. I would say....schedule a pull when temps and humidity are down....and make sure you're in the proper gear to make the pull. I would have thought you'd have pulled more than you did as well.
Don't get too bent out of shape...lots of variables that can really impact the bottom line when making pulls.

The numbers wouldn't change THAT much, but would probably be lower in 4th, due to needing less power to accomplish the same amount of work.
They may do them in 4th, if 5th is going to make you hit the speed limiter on the car.

I'm hearing from others on a local forum that this is a well known low reading dyno and my numbers are in line with similar mustangs.
