Ok I used this site http://www.thearcheryhut.com/calculators.php to figure out the specs.

if you use the Nitrous with the Vforce 350's at 370 grains 60# draw and 28" draw length 309 IBO (I find the lowest number on bowtech's IBO rating is the most accurate for this.) you should be getting 281 fps and 65 ftlbs of KE.
