But Matt he is in the insane hp crowd I have heard of a lot of p pumps sticking plungers on pulling tractors. that is why they have fuel dumps,air shut offs and other saftey stuff. I have seen one start to take off at the heavy end of the track and it didn't take long for the operator to kill it.
He may not be even using a p pump there are other pumps out there that are used in it's place so I am told, but a sigma (sp?)pumps are very expensive. I don't know
