Default Walbro fuel pump 255?

How much power can a walbro fuel pump feed? It's a 255 fuel pump and what injectors would go with this fuel pump. I'm doing a heads cam combo Texas speed. Thanks guys

Basically what I'm asking is what's the max power with that fuel pump and what's the minimum power?

Well I have this pump with Texas Speed heads and cam, and with 42lb injectors it has more than enough fuel to support the power

Well I just recently traded a Mustang for this car, so it came with everything that you see in my sig. Couldn't tell you what the parts cost sorry. Power?? Well one dyno said 460 rwhp and another said 405 rwhp...that's why I don't trust dynos lol The cam is really loud but a lot of it has to do with my exhaust setup. As far as the nitrous goes, it's all hooked up and ready to go, but the car isn't tuned for it. From what i've been told my fuel pump and injectors should be fine with a 100-150 shot. Are you looking at the same HCI setup that I have? What gears are you running?

550rwhp is the single 255's max. Anymore than that and you're going to have issues.
