Exclamation Dyno sheet

bought the car abt year ago.today i was going through some old paper and found the dyno sheet for the car.it shows the max power with WCF and without.wht is WCF?kinda confused on whts the max power.pics are below.
the car has:mild cam(would've been nice if the last owner would've told me the exact cam.he didn't know) hookers super headers,borla exhaust,ls6 intake,and injectors,4.10 rear end.according to last owner heads were redone(he didn't know wht was done to them)and the car is dyno tuned.and its m6.so the result its showing on the sheet, is tht abt right hp it would put down.[IMG][/IMG]

weather correction factor. Relative to 77 degrees and a barometric pressure of 29.92 at sea level. It was probably a hot summer day in Wisconsin at about 1,000' elevation.

At your elevation (sea level), 77 degrees, and 2992 pressure- 420. On a cool day in Orlando, say 50 degrees with a pressure of 3020, probably about 435ish. If you drove back to Wisconsin in July with hot temps it would be back down to 360ish. Google weather factor correction and you can find a calculator for all this.

I would not even consider those corrected numbers to mean ANYTHING. You have a 15% correction there and i may be wrong but that is probably twice what the J1349 correction should be.

Search says Weather on 7/7/2010 at that zip averaged 86 deg, 83%, 30.06 sea level.
Your correction factor shoud be about 7%.

387 hp corrected
396 tq corrected

That could be just a spike at the beginning of the run that it picked up as the peak. Without looking at the graph, that is not too much to worry about.
