well I have the fallowing done to my coupe
306 forged pistons
eddlebroke 2.02 heads.
e-cam, 1.6rr
bbk shorties,bassani x-pipe,pullies, 75mm MAf
70MM throddle body, 30# injectors, 255 intank
, and a NOS kit

I now I have enough fuel psi to run N/A and even
anough to run a 125 wet shot

my ? is do you guys think my 255 intanks is enough to keep up, if I run a 175 wet
or will I need to put a external fuel pump

thanks

I don't know, this is SECONDHAND, but people tell me a 255 in-tank is enough for my combo. I currently have a 190 in-tank and 190 external. My combo, once again:

So lets say your motor makes 270 rwhp NA. On the bottle it'll make about 400 rwhp.

30 lbs injectors at theoretical max 100% duty cycle need 150 lph, add 20% for the return line and you have roughly 190 lph.... so now you have the wet kit consuming fuel off this same pump... you have a 'spare 60 lph to play with here. I don't know how to calculate how much lph of fuel a 175 shot's wet kit consumes since I have no data on it, but 60 lph is a lot, even with out knowing the numbers, I bet you'll be fine.
