Vishnu looked at my graphs and told me I have 400BHP!!!
It seems like the general consensus is around 12%15% difference between the two dynos and if that is true I am pretty satisfied. Also the guys at COBB were really cool, and I think 2 of them drove BMW's (the other 10 or so cars were Subarus, 350Z's, and a G37). They seem like they make a great product! I wish their CAI fit our cars I was the second 335i to have ever been dynod there, so they did not have any other data. Although the other car had a Vishnu tune and cat back and had about 330 hp and 377 tq. on 1.47. Not sure what settings he was running, but they did have his boost recorded at 15psi max. Anyways. All in all I am very happy with the cars performance, even if these numbers seem a little low. I have had 0 problems with either of my mods so far, and am excited to get a CAI on here to see how it changes these numbers. Not that cool but here is a pic from my iPhone (they made me sit in a glass room )

15% is a little on the high side, but not inacurate! I tend to stick to 12%, but either way the numbers are pretty darn good for 91 octane at elevation.

If this were true, then our cars would be faster than cars at sea level. Which is not true.

M&M, at 5500 ft. trapped 113mph using PRocede V 1.47
Engine Power's relationship to air density is less than linear. Drag's relationship to air density is exponential. At lower speeds, it won't make much of a difference, but as you go faster and faster, the "advantage" of being at high altitude becomes more obvious.

The biggest issue with that dyno run is that the car is still making power when the test ends at 6600rpm. There's more power by just expanding the test RPM range and nothing else.

I didn't mean to start anything, but this STILL seems low to me. I guess some can be accounted for by the Mustang dyno. I just did a quick search and came up with relatively higher numbers on others running V2 or V1.47 on a Mustang.

Maybe so but Darrin posted
"I have aa exde and ur catless dp plus agency power exhaust,I have 328 whp and 374 tq and mustand dyno with 91 oct.Good luck u,I hope u get more than me." AND the OP had 361 WTQ without exhaust,...only V2 and CAI. RWHP wass minimally different without exhaust that this threads OP has. I know exhaust may not make up that much difference but it should account for some of the HP difference.

From what I have seen 1215% is about the difference on the mustang dyno. BUT there looks like there is an issue with this guys dyno... why did the run stop at 6600? Also was this a auto or manual?

Hmm, a Helix customers car put down 340/346 on a mustang dyno. Using the logic from this thread, they made 391/397!

different octane, different altitude, different supporting mods, different dyno (more significant on a load dyno than on a dynojet as mustang/dynamic require calibration and a dynojet is just spinning a heavy drum).

Do mustang dynos have SAE or STD correction factors? If so, did the OP use these factors? If so, then the elevation should have no affect on this dyno then.
