Predator temp and rpm question


New member
I know there will b a few different opinions but I'm just curious of the max temp and rpms I could run before it starts to loose power. Hf predator 212 sealed with governor
and oil sensor removed. Also running a weenie pipe.
One last question lol. Which of the hf# predators performs the "best"
Out of the box a 60363 does better on my dyno, and 5200 rpm on it..5500 on the others from my experience. (don't know about with a governor tho)
