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 :-\

Mustang people use those for over 500 hp.

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

Re: how much whp is the walbro 255 good for???
 

why the ---- is a stock mustang 88lph? do you realize that this is less than HALF of what comes stock in any other 5.0 efi ford at 190lph?...

mista bone said it himself, 190lph..

Re: how much whp is the walbro 255 good for???
 

255 is good for at or over 600 whp.

Your stock fuel lines get scary at 500.

this is a 110 lph that is labeled as a high flow. so stock must be below 110...they also offer a 155, a 190, and a 255
my other car is an 89 mustang coupe...ive been working on mustangs for a few years now.
