Oh, and the cold air on the dyno helps haha.

That's what correction factors are for ~ standards.
It would be different if I had done this in winter time and shown "uncorrected" numbers as opposed to SAE or STD.

For the most part, and generally speaking yes... BUT...
So with all the discussions about snorkels being on or off, I figured I'd post this :
In the case of the AiRaid intake, some had said that leaving the snorkel on would mean
up to a 20% restriction. Would you like to guess which run was with a high CFM carpet fan blowing at the intake (in addition to the hood being open and another dyno fan blowing) and which was without?
I brought this up when @
mechaghost posted his findings but some people were more keen to see better numbers then I think.
