A little help correcting Dyno numbers

Adam, do you have the runs on a 3.5" floppy? If so you could either mail them to me, or go to www.dynojet.com and download the runviewer program (~2.4M file). The runviewer will allow you to select any of the common corrections, SAE, DIN, STD etc. The dyno condtions will already be loaded as part of the file.

That would sure be nice, but I only have hardcopy. I know http://www.wunderground.com/ has the weather from each day. I just can't actually figure out how to look it up for that day and I want to be sure I use the equasion right. Any help is very much appreciated. Thanks and thank you chip!

Thanks Steve!

EDIT: Should I use the mean value for temp? The runs were done all day long. Anywhere I can look up the altitude of Orlando? Thanks!

Orlando is about 100ft above sea level. Plug in the low and the high temp for the day and you'll see there won't be too much difference in correction since the temperature range is small (and since both temps are near 72 deg F).

Thanks again steve! New numbers on the way

After all that the CF is 1. Man!

Thanks for the CF link. Good info.

Chip and Adam, you're welcome.

Adam, yeah your Cf was between .99 and 1. Heh. (But now you know how to calculate it.)
