We came accross a smoking deal on two of these units. First off I was wondering how good of a machine these Lombardini diesels are and what would be involved as far as upgrading the machine to support a higher gpm with slightly less pressure? The units currently have 200hrs on them and they are rated at 4gpm @4000 psi.
 
all you should need to do to get more gpm at a lower psi is to change the pulley ratio. Spinning the pump faster will produce more gpm. Just don't over do it.
