You really need to watch your grow and decide, but I've found with my past grow that 90 was ideal and 92 was the point where I wanted to vent the room and start the co2 all over again.
Peace

With c02 added what would you say would be the maximum tolerable temperature would be without stunting growth. I know this can also be dependant on strain and/or genetics but just a ballpark figure would be very helpful.

wow that is more in my range than I thought. The thing is that I have a very stealthy grow box 16"x24"x12" and now that I have added mylar and my reflector it has raised the temp considerably i.e. 84 deg F to 95 deg F. I have two small pc fans running one venting out and one bringng cool air in .... in your experience would I be better running them with a passive intake or an active intake? i.e. both exhausting or one exhaust and one intake

Great question, both should be on exhaust. And your intake holes should be 1.5 times the size of the exhaust.
