My brother-in-law is a 2.2L shelby charger (mopar) boy and recently got the super 60 upgrade. He says that the pump is 255L/hr. He said its basically a Walbro. No difference.
I didn't ask that, but I would doubt it. Super 60 injectors are in the low 500cc/min. You must have a line on a cheap super 60 pump then, because an aftermarket walbro is probably cheaper than the super 60 from satan.
