injector nozzle %'s

wondering if some could explain what the difference is or how they work. My 190's are from Casserly at Full Force Diesel and were purchased back in late November of '08. They've been awesome so far. I talked to Ryan a while back and had asked him how my injectors are different from the ones he builds now. He told me that the end performance result is the same, but said that there has been some changes/differences to get the same end result...and that my 190's still flow the same as the 190's he builds now. I was also told that he started using the newer style nozzles in early '08 and that my injectors have the newer style nozzles.

So what i'm wondering is...when you order a set of 190's or whatever size from any injector builder, what % nozzle would it normally come with? Is a 75% or 100% nozzle extra? Just kinda wondering what % nozzles mine would have cause i've been reading some threads now of guys having 75% or 100% nozzles and wondering if this is something new with the injector builders.

Re: injector nozzle %'s

depends on what nozzle is necessary to flow 190cc's of fuel, if you are running a 155 you really only need about a 50 over nozzle but the 75 over gives you a little room to expand without renozzling

So basicly you're saying a 155cc injector with 50% over nozzles will flow roughly 190cc or is equivalent to a 190cc injector?

Re: injector nozzle %'s

this is going to start a huge confusing thread for everyone. %'s are all screwed up. the different process in how the nozzles are made makes a huge difference in flow.

Re: injector nozzle %'s

no, but you only have to run a nozzle percentage to flow the amount of fuel at hand, for instance a factory 6.0 injector at 135cc's has a factory nozzle so 0%, so if you run a 190cc injector with that nozzle you won't be able to flow 190 because its physically impossible for the tip to flow 190cc's of petro

all nozzle percentage numbers are how much there capable of flowing over factory, and as matt said all nozzle brands are designed to work differently, subsequently you may need a larger nozzle % depending on the nozzle chosen for a particular injector

Re: injector nozzle %'s

Maybe this is something i'll hafta ask ryan then. I've just been curious to know what % nozzles my injectors have since he told me that i have the newer nozzles.

its not technically impossible for that nozzle to 190cc its just that it will take much more pw to do it.

true, true, but with that much pulse width i think you might run into some issues

Re: injector nozzle %'s

i think i'm starting to understand now. So a 155cc injector will only flow 155cc if the stock 0% nozzle is changed and made 50% larger?
