Concern about 2 stroke race gas kits

[Spur]

I've been thinking about building a race gas kit on a new Cat. I have a concerns I need to figure out before I dive into this.

I am coming off of a T-Nytro and a couple T-Apex's before that. I love them both, just thinking about doing something different. I am not interested in a pump gas kit. I have rode lot's of them, and I know there a lot of fun, but I can't go where I need to go with the guys I ride with on a pump gas kit. The thing I'm worried about is the two race gas kits I rode with last year had to stop and cool down after long hard pulls. Every time they tried to keep up with the 4 strokes they burned down and had to be air lifted out. Can any of the 2 stroke kits out there keep working hard like the 4 strokes do without needing to stop and cool down? I've owned enough big bores that had to be cooled down, I don't want to start that again.

I may be stating the obvious here but while I have no personal experience with these kits I don't see how you could get get a 2 stroke turbo to hold up as well under extreme use as a 4 stroke for the simple reason of heat disipation. A 2 stoke obviously has a power stoke 2x as often as a 4 stroke running at the same RPM, this gives the 2 stoke less opportunity to cool off and will become heat soaked much faster.
