Injector holes-more is better?

smoke'em should have some good info on this. Jim Fulmer to.

Its hard to say anything man without bashing the other injector. just say you get what you pay for.

Depends , I got a set of new injectors cut to were I wanted and they cost 500$ and outperform injectors that I paid 1200+$ for... I pitted anyone who pays over 800$ for 24v injectors
 
Whose were you comparing them too, there is a good chance the $500 injector place made the injectors for the place that charger $1200.
 
What's difference in a injector that ups the fuel economy? Is it pretty much stock with smoother holes?
 
I have a set of custom injectors in my truck and just pulled them to have them tested and cleaned good, and never really noticed before but they are 10 hole. Looks like the normal 5, then a set of 5 much smaller ones further up. And by up I mean up away from the tip. Anyone ever run ones like these? Gonna have them flow tested. I bought them used so didnt get much specs.
 
yes more holes is better for atimization but the last thing u want to do is to blow the end of your injector apart for abvious reasons there is a reason why 5x.018 is the most used injector 1 strength 2 reliability 3 great performance 4 good atimization
 
IMO, there's no benefit beside less smoke and maybe better mileage. This from the horses mouth at 2 dealers I know of selling 10 hole tips.

Thanks for bringing that up. Its in my opinion that people should think about the so called hp ratings on injectors as there are way to many other factors that go into making hp with these trucks. Smaller injectors that one would use on stock chargers like 370's I can see placing a round about hp rating on them. But as you get larger were many other factors such as turbo's and modded pumps come into play the hp number can be all over the place. Just food for thought...

Don made this page, good info and a good comparison of the blind-hole nozzle to the VCO nozzle.

Hmmm interesting.... So would the 370's and 435's have the sac hole style tip? Maybe that's partly why they haze so much at idle???
 
Spray angle of the marine injectors causes fuel to hit outside the piston bowl, contributing to haze.

I realize that on the 370's... They're 155* vs the 145* that our trucks usually run... That's why I threw the 435's in there too, cause those are (usually) modified 370's that have been corrected to 145* IRC

EDIT: I only asked in the first place because Don stated in his write up that only the Dodge applications of the B and ISB had the seat hole nozzle design...

How do you "correct" spray angle??

I'm just not sure how effective that would be...In my small mind, it seems you would get more of a "fan" injection, rather than a precise spray.

Basically, rather than having a . for a spray hole, you might end up with '

ie, a "longer" hole.

I see what you are saying... But I would assume that is why they have to make them bigger. IDK maybe someone who knows what they're talking about will correct us??? :bow:
 
A longer injection hole is for better atomization, which affects how wide or narrow the spray pattern is
