2 is better than 1
i have been looking into doing a twin hpop set up, the thing i dont understand is why are these kits so expensive? it seems easy to me, just get to pumps and plumb them together, i am no expert though. but i think i would go buy an overdrive before a $4500 fule system; that includes injectors of course

I am working on a dual HPOP system using two stock pumps (or possibly two stock style 20* pumps, stacked on top of each other. BTS uses a 530 pump on top of the stock pump, running in reverse. They have a cam adjustment for the gear backlash, and it is a very well designed setup. The biggest thing is getting a block of aluminum CNC machined for the pump to bolt to. Before we go and design the dual HPOP system we are working on a 20* swashplate for a stock pump, and hopefully that will cure most of the people's P1211 code. Then if that works well it will be relatively easy for the machine shop owner to make a dual setup.
