I don't think there's a significant limit on number of techs (applications) but you can only have the number of levels (theories) that exist in the vanilla game. Even having less tech levels causes a crash IIRC.
 
Not less but can there be more?

Okay... but what about having more tech levels? Is there a cap on the tech levels? Like if they're expanded to include techs past WW2 for example so it can transition from WW2 to a Cold War era mod thanks to the No Time Limit patch?

Thanks,
Richmond

As I said, you can only have the exact number of levels that vanilla has. If you want to extend the tech tree beyond WW2 you either need to compress all the existing levels to free up some at the end or just make all the post-war techs in the highest level and have long chains of pre-reqs. I think the Modern Day Scenario and Cold War Scenario people were remaking the tech tree completely.
