4wd gearing. Motor temp etc
What sort of motor temp is safe?
My 4wd this weekend was coming in after 5 mins with can temp of 90 to 92 degrees c Car felt a bit soft on power. Zero boost Zero turbo. Hw 2.1 esc Orca 6.5 tx motor. Pr SB401 buggy running 22/77 pinion and spur. Could do with a bit more grunt from it But with temps like that im nervous of boost or turbo. Is it maybe time to look at a new 5.5 motor

What sort of final drive is it?
Might be worth experimenting with dropping one (or two) teeth from the pinion. And checking you are getting some airflow through the shell! |

Yup as per the other posts gearing, go down one and see if the punch is more and top end should be good also. The other option is a motor mounted fan, a big one. Demon racing does a few large ones and the mount is alloy as well so always a good investment as that made my Sworkz 4wd want to be pushed whereas without your wondering if its going to last

+1 for motor fan. It was hot this weekend and with high grip Astro, it can push temps up - I even fitted one into my 2wd this weekend! Sounded like a hovercraft but made a massive difference in temps.
