I have seen the video and I understand the physics behind the theory but I still don't see that kinda heat being generated on a 30 min run. I'll definatly check it out. I'll run my truggy for 30 mins like in a main and then take the temp of the shock oil. Who knows I may be surprised. But I don't get the heat part.
