Xtra fueling using bigger DI injectors

[FieSTafury]

So I know back in the day of the LNF Cobalt SS, one of the works arounds of getting more fuel to the injectors was a custom cam with bigger lobes on the fuel pump side. I noticed in my HP Tuners software that there is an option for either a 3 lobe or 4 lobe fuel system. Has anyone tried a 4 lobe cam for the increased fuel volume? That combined with bigger injectors should be enough for around 400whp no? Of course I like the idea of a 4 injector port fuel option too, specifically to keep the valves clean.

The only place that makes larger injectors is Pumaspeed...they are $800+ for a set of 4...a cam if possibly would be at least $3-400...then your in the range of Perons and Stratifieds Auxillary setups.IMO.

How well it works, I have no clue. But if it does work as advertised, it should fill the need for some that aren't going for mega horsepower.
