could be either way, I've seen both. 6 injectors rated at 160lb/hr would be way too much for a 850hp motor anyhow, that's for more like a 2000hp application. although I guess you could always dial down the fuel pressure, but im sure that would run like horse shit
If what you're saying is true, the fp would have to be so low, the injectors would not be spraying efficiantly. The fuel would kind of dribble out. An 850hp talon is more than possible, just ask Buschur Racing, but I'm not sure if they really know what they're doing. Anybody can watch supertunertv, pick up a drag racing catalog, and say I'm gonna do this, this, and that.
