So I have a 4k, 7mm DV's, 180 pump, 5x.012 and a super B with a 63mm inducer. I certainly need more air, but hey, turbo was cheap lol. It's a projected 550hp build, but until I get my fuel (more so lack of) issue fixed, I can't dyno it. drops to 0PIS at
WOT.
I would think that 5x.012 injectors would be enough for 400 hp. Hell, if PDD sells 5x.012's in their 550hp fueling package and they test literally EVERYTHING, wouldn't that tell you something? 5x.014's would make you smoke more than you want and certainly haze quite a bit.
