HP & Density Altitude ?

SmBlkFord · 05-25-2013, 09:41 AM

Trying to figure a couple things out. Will a higher HP motor be affected more by weather changes ? always thought less but it takes more HP to go 8`s then it would 9`s,Can anyone verify ?

I believe that it is a percentage correction. Therefore higher HP will lose/gain more from changes in DA.

It will lose more HP, but because it takes more HP to lower ET as you get faster, high HP will be slightly more consistent ET-wise for the same change in weather conditions. Yet another reason to take a second mortgage to go Super-class racing.
