Long story short; I didnt like the operation of my Ingram race pump so I decided to do a little exploring. What I found; or what I didnt find was very interesting. The 3D cam was highly modified. There is a land milled around the cam and the centrifuge system has been completely removed. Here is the cam:





The modified cam was also held to the crank shaft of the pump via a set screw. Essentially this pump is full on no matter the throttle position. Is this fairly typical of the modified pumps or something different?
