I have seen those videos before and thought they were pretty amazing. If you put those trucks on dirt they would prob bo more in the 60 to 70 pound rande....Which is still unbelivable! Even on our track their is no way that those pulls would be possible.....there just isnt that much traction availble, once we start to loose momentum then it is all over. We cant sit their and walk the trucks down the lane. I will get some videos of my trucks pulling on wednesday night.
