I know for a fact, that putting a 255lph fp changed the pressure from 39 to 49psi relative, High pressure can cause an injector to rupture or something to that affect. I think its safe to say about 150lph before the pressure goes above relative.
I think stock Taurus pump is probably around 110lph.

155 , remember some ATX came with SLO pumps (6? lph).

Vulcan fuel pumps are 60LPH stock.

what year is your SHO?
if your an 89 or 90 you have the resistor that drops the voltage,you can run a 255 with no issues. no real benifit to such a large pump,a 190 will handle more fuel than the lines will anyway.

190 is the highest I would go, and 155 would be better for correct fuel pressure.

I'm wanting to run a 100 shot as safely as I can. Would a 155 be good for that or should I bump it to the 190 to be safe?
I will be running a 55-75 shot until I can get the new pump. I just bought a factory replacement so I'm sure it's fine for those levels but I want to be good for the big one.
It's an '89.

being your car is an 89 id get the 190.
honestly i would not run any N2o on a stock fuel pump,a 35 shot maybe.

35?
I think 155 should be able to supply the injectors with enough fuel for their duty cycle. I would contact drivinhard on the board here. He has been tracking his car and running nitrous for many years.

IIRC the Zex kit comes with jets for a 35 shot.
