1997 vmax 700sx vs 2003 mxz 800 renegade.

i asked a friend to race our sleds. i have a new 1.5 intense cross country track on the way to replace my worn out kimpex shotgun track. i wanted to race him before and after install of the new track.
my redhead has psi triple pipes, vforce3 reed cages, air box mods, heel clicker primary, 21/40 gearing, extra-10 skid, 121 x 15 x 1.2 shotgun track that has very few lugs down the middle.
he has a 2003 mxz 800 rengade vforce3 reed cages, heel clicker primary, stock pipe, stock gearing, stock skid, 137 x 15 x 1.25 stock track that has most of the lugs gone on the outside edge.
what are my chances on beating him with the shotgun track 660 feet, 1/4 mile, 1/2 mile, 1 mile. and
what are my chances on beating him with the 1.5 intense cross country track 660 feet, 1/4 mile, 1/2 mile, 1 mile.
