We found out today that the motor that smoked before we modified the cimulators had developed a case short and so we are no longer using it. Hopefully that will not happen to anymore rs550's with these cooling slots added.
We also had an ir thermometer with us today and although we don't have non modified temps to compare to, after 2:30 flatout the motors were at 105F and 115F, and the transmission was at 95F.

All the slots let air in the front of the motors, the motors suck it through and the small fan in the back lets it out the un-obstructed holes. Tomorrow I can get a picture of it with the motors mounted.
