Power Loss at Elevation

SonicVQ

The dyno sheet doesn't show a correction factor number... It only says the correction factor (CF) is SAE, and that the graph "smoothing" is 5.

Here is the problem.... there are two correction standards for SAE:
SAE J607 and SAE J1349.

Generally the J607 (aka STD) is about 4-5% higher than the J1349 standard.
This is due to it factoring in about a 15% loss due to friction.

The dyno results are just numbers on paper. It is very difficult to get accurate and repeatable chassis dyno numbers and on top of this, each engine is a little different.


If the car feels better after the mods, then all is good

If you can post the logs, I will have a look at them... I am curious how the elevation changes things.
