So Mark... where's your 1/4 mile guess?  You were one of the folks highly suspicious of CO dyno figures  ;-)
 
Anyway...
Several of us in CO have been using the MAC Autosport dyno.  On the printout, and on the runviewer software, it allows you to select a correction factor.  The default is SAE.  Once you do a run, the printout shows the correction figure used for our conditions, which include temp, and pressure.  The correction factor is supposed indicate what the engine would do at standard temp and pressure.  On my last runs, the correction factor was 1.26.  442/1.26 = 350.8.
 
SAE says that an engine putting out a "true" 350.8whp when it's 95 degrees outside, and at 5000+ ft is equal to 442whp at sea-level, and 70 (or 68?) degrees.  This has been the hotly debated topic.
HTH,
Dave

How are you getting the SAE vs raw conversion numbers. 
 
I last ran a 343 WHP RAW, NCFS... so that should put me where corrected to SAE ? 
 
Thanks
