what goes into making a 150hp nozzle?

does anyone know the differances in a stock nozzle vs a 150? other then flowing more, is it just a larger hole? Would a good machine shop be able to turn my stock nozzles into 150's. Only reason I ask is I can get machine work for free, just not sure if there are any other differance's. Does anyone know how much they are opened up?
 
Anyone can make injector nozzles flow more, it's actually pretty simple. Just remove the nozzle from the injector body and then remove the pintle from the nozzle. Find yourself a very small carbide drill bit, .015" is a good size to start with. Be sure to clamp the nozzle securely in a vise because you do not want the brill bit to wonder as you are enlarging the hole or you'll end up with one hole larger than the others and/or a screwed up spray angle.

Sounds good, about what would that equal out to for aftermarket sizes?

about like a dragon flow

whe you get the bit all the way through, if you wiggle the drill a lil bit then they are about the same as super dragon's

The bad thing with that...when you wiggle a carbide bit they break and the whole nozzle is trashed.
 
I put a spare cp3 into a drill press, cranked the press up to 2k rpm and ran a closed loop of a Portland cement/ water slurry through all 6 nozzles at once, and flow honed mine, I figured when the cp3 wore out from the abrasiveness of the fluid the tips were ready.
 
Fukk drilling. It's too hard, and you need tools. It's just stupid.

Remove the pintle and pack sand into the pintle bore. Then. Blow through it. Repeat. I think like 65 blow cycles is = to 150.

Mike did you use the Quick-Set Portland for that?

you got it, quick set, make the truck even faster I figure.... ya rekon ?

Yup faster is better ... im gonna stop by True Value tomorrow and see what kinda special grout I can find for this, drill em out and then mix up some grout to hone out any rough spots, this would be the same as EDM'ing and Extrude Honeing.........:ft:

I guess if I wanted the whole thing to go faster I could add edm to the mix, just run an extension cord to a coil off an old chevy and then one lead to the rail holding the injectors....

Glass media like you would use for blasting cuts faster so it takes less blow cycles, it also leaves a very smooth satin finish on the inside of the holes which in turn makes less resistance as the fuel flows out the holes. This also means that the holes do not need to be as larger to get the results that other methods of injector nozzle modification produce. You can also drill a second nozzle feed port into the injector body but then you must also drill the nozzle to match the body...there are so many simple mods that one can do themselves.


P.S. If you really want the nozzles to make a clean, efficient spray you need to have the inside of the holes chrome plated.
