Titan Speed makes a billet alluminum pump that you can crank stupid pressure and stupid volume if you desire. I had an oil pump break in the main body one time and decided I needed this pump. The rotor is about 1 1/2 times longer than the HV 72. It also uses a different shape rotor(like a ford). This pump requires some pan work also. The pump was just way to much volume for me and when you regulated it down to 80 psi, which it will hold at a hot idle, it was just burning up HP. I now use an external pump from SCP.

My HV72 pumps right out of the box would make 85 psi through the traps and 55 idling hot. I did run a roller cam, oiled through the pushrods, and ran a needle bearing cam bearing. Probably could have easily gotten away with a stock pump.
