I know you are at a higher elevation but that still seems pretty low. Is it a mustang dyno or dyno jet?

and wat the hell, it sounds like he doesnt even have it floored and he gets into it than lets off than gets into it again

Dynojet 224x dynamometer.

I feel like they were low too. Similar to other Mustangs with the same mods though, so I guess it's accurate.

I agree. Don't know what type of loss you have at a higher elevation but that does seem low..strange sounding dyno run..If you applied the old drivetrain loss number of 17% that puts the car at 418 which is stock basically. Some would argue that these cars only loose 12-14 on the high end of that you are at 408. I did find this high altitude calculator though I don't know how acurate it is(seems to be a consistent calculation all over the web though) HP Loss = (elevation x 0.03 x horsepower @ sea level)/1000. So for you I think you said 7000 feet??..7000*.03*412/1000=86.52. that puts it in the 440 range. Its probably a bit of a stretch that it would turn 440 but 425-430 isn't out of the question..just food for thought. At least you aren't throwing any codes.

Is your car auto or stick? Cause 6 speed cars with intake and tune put own on average 400rwhp. I doubt youd get a 50rwhp loss from your elevation. What was your AFR?

Actually, at 6700 feet above sea level you EASILY loose that much horsepower. Especially if weather conditions make the actual density altitude even higher, then your horsepower loss would be more.

At 7,000 feet a 100 horsepower engine in the light sport airplanes I fly is easily down 25 horsepower. A 412 horsepower engine being down 50 at that altitude is more than realistic, it is actually conservative.

I don't know what the temperature was yesterday over there, but assuming an actual elevation of 6700 feet, using this morning's reported baro reading of 30.13, an assumed daytime temperature of only 50 degrees, a dew point of 34 degrees, you get a pressure altitude of over 7500 feet. You are going to easily be down 70 to 80 horsepower at that pressure altitute over someone near sea level.

Knowing what I know about these things, I think the car did very well myself.

So my goofy math calculation was correct?? I came up with an 86 hp loss. Back out drivetrain loss and he turns 420-425..aint a damn thing wrong with that..good tuning my man!

MoshpitMad

Uncorrected numbers were actually 284whp. Elevation with all factors was close to 8000 iirc. So, this is corrected to represent what sea level numbers would be.

Car is a 6speed, and has 3.31 gears. These numbers still seem really low to me.

Holy crap!! Those were corrected numbers? Yea something is definately up that's just way to low for that set up

Where did you take your car for the pulls? I want to get mine done but don't know of any shops out here.
