PHR tests correction factor, 'splain please.

[Steve1968LS2]

Just to be clear Steve, I am not calling you or Westech out here. Simply trying to understand why the "correction factor" dosen't seem to correct to anything close to a "standard day".

Oh, I know your not "calling me out"

That's why I put it in both engine stories.. to make it clear. There are certain correction factor formulas that you can choose from. In other words (as far as I know) you can't make up your own correction factor, at least easily.

I guess a standard day depends on where your are located. A standard day in SoCal is not a standard day in Orlando, Florida or Detroit, Michigan. The OEM's use the 70 degree one and most other places use the 60-degree one. Most likely the OEMs want to be conservative and the others want to be generous.. lol

However, the important part is that the correction factors are given and that the before and after tests both use the same factor.

We have a story coming out in the December issue about "dyno shenanigans" and the tricks some places use to inflate the gains made by stuff.

On a side note I am very proud of my opening shot at the dyno.. I'm a newbie at this and the shot came out better than I had hoped. I also thought it would be fun to see the actual dyno screen.
