Mustang dyno results fishy

I found this on a local board and it looks like the WCF is a lower number..
That is the Weather correction factor that corrects it for the weather right?
So I guess the 488 rwhp would be comparable to an "uncorrected value" and the WCF 448rwhp would be comparable to sae corrected power?????
Am I missing something?

Because they are boasting the 488 rwhp like it is some outrageous number with the trick flow heads..
I beat that number with my junkyard 6.0 block and patriot heads....
so the real number is 448????

I would say yes..448/390. But, don't hold me to that as I have never used a mustang dyno...On a dynojet, corrected means just that, so I'll assume it is the same on a mustang. Some one will jump on here and tell you the answer for sure....448 on a mustang is pretty good for a stock cube LS1.

Weather correction is the same on every dyno. Mustang, Dynojet, Superflow, Go Power... ETC. Chassis or Engine dyno. Now everyone knows there are different correction standards but dont let a higher uncorrected number confuse you here. That is WHY you have a correction factor. I think most people are used to seeing a higher corrected number and that is what is confusing you. If you make a run at any conditions that are "better" than the correction standard you will have a lower corrected number.
Example:
Say your standard is 77 Degrees, 29.235 hg, and O% humidity, 85% mech eff.
Your testing conditions are 45 Degrees, 30.20 hg, and 10% humidity.
You will have a .93 correction... or about if I figure right. (You get the idea anyway). Your uncorrected 450 HP number will be 418.5 Corrected.
Run the same engine, except on a 105 degree day, 29.50 hg and 60% humidity and you get around a 1.077 correction. Now you are NOT going to make a uncorrected 450 hp number, math wise you should be around 389 UNCORRECTED NOW but your corrected numbers SHOULD be back in the area of 418 or so.
That may not be clear.... and dont quote the figures I am just using them to try and explain to you why you dont always have a higher corrected number. And remember all the different SAE corrections out there also.
Hope this helps. If not just ask.
