it really depends what car you are talking about - also depends on what you mean "take it"
the lower end tamiya cars with some modern gearbox designs might be able to take the power in terms of gear strength - but they migth have plastic motor mounts which wont cool the motor, and also might warp if they get very hot.
and of course a really fast motor in a car that doesnt handle well wont make much difference over a slower motor. I saw one of their latest 2wd buggys recently, it was really quite bad handling with the friction shocks.. add some proper shocks and it would have been SO much better.
