MachV motorsports, which is a very well known dsm supplier/shop/tuner says the walbro 255 lph will support 550 hp with a dsm, so maybe its good for 500 whp, but if you reach 600+ whp you should go bigger, i know a guy with a 506 whp civic and he uses a 340 lph pump :-\

a 190 lph pump will support a 450 hp 347 and 150 shot, good enough to run 9's in a Fox body.
