i would go with the 5x14 thats what im putting in my truck had them in my old truck there great and i had a ats 3000 turbo and the injectors made it light up a lot faster

im running the sdx 7 holes and love them

my 7x9s are around 100hp and are super clean

I'm going to 7x11's. I have a buddy with 7x10's (real close to 5x14's) and he says the smoke is way down, and turbo spools faster than his old 5x14's And he picked up 1 hp on the dyno, but lost 25 lb/ft of torque...

a 7x.010 is just a tad smaller than a 5x.012

Yah, but my buddy has dyno sheets from the same day, on the same dyno to show that horsepower stayed even betwixt them.

this would tell me that either he has a fuel supply issue, need to upgrade some things on his p pump, or he doesn't have the airflow for the bigger injectors.

Did you consider that maybe a cylindrical blind-hole nozzle may be superior to a vco nozzle? He is not the only one that has dyno results to prove this. People look into cross sectional area way to much. Look at a micro blind nozzle with the same hole count as a vco nozzle. They have the exact same cross sectional area but will not make the same power.

Your saying a vco 5x.014 VCO will be out flowed by a 7x.010 blind hole dispite the massive difference in cross sectional area? I'll agree with the same size vco against a blind hole statement but not so sure on the other.

The dyno mentioned earlier was a 5x.014" vco nozzle vs a 7x.010" cylindrical blind hole, both with stock pintles. They do not offer a 5 hole cylindrical blind nozzle, at least not one that is not custom machined.

I never said a 7x.010" will outflow a 5x.014". The 7x.010" will flow less but it does seem to make decent power, despite being smaller. Some testing has also been done with a set of DDP4's vs SDX 5x.014" vco with lift vs 7x.012" w/out lift. The 7 hole injectors had less haze and had a significant increase in power vs both 5x.014" nozzles. There is still much more testing to be done with various 7 hole nozzles.

I have to go back to stock now. I dun spent too much to quick!!!
