Stock fuel pump capabilities?
How much power are stock C5 fuel pumps usually good to?
I'm having some weird fuel pressure issues on spray (100 shot) but we haven't even reached 450whp on the mustang dyno.
Actually, we've barely broke 400
Replacing the fuel filter today to see if that's the issue.

I have stock fuel system, stock injectors, stock heads, intake, and internals. I have long tubes, no cats, borla stinger cat-back and AFE air intake. I made 478hp and 590ftlbs on a 150 shot! The stock fuel system will support just a little over 150 shot!

I have heads/cam/100 shot and I believe im getting detonation when I spray. My stocker is more than maxed out. It was fine on the dyno but whens its loaded on the street, thats when I think it goes lean.

Thanks guys! That's what I was hoping to hear!
Chris, have you logged while you're making a pull on the street? Wouldn't be a bad idea so you can see what's going on. What kinda plugs are you running?

Mine is similar to yours, It seems to run great with the NA run but when spray kicks in, I get bad spark knock I believe. I think its time for a Fuel pump but we'll see.
What Fuel Pump are you running?
