A/M injectors and tuning

[smokersteve]

Hello, My question is about the injector size from 175c and 190cc, and I am wondering about different HP tunes and the inj size.
So far my future plan is to get the Powermax with 175cc from full force.

What is the difference of injection quality between a 50HP tune with 175cc and a 50HP tune with 190cc.
Will the 190cc injection ignite the fuel faster?

I am not sure I asked the proper questions so here is another way. I would like to know if the 190cc will ignite the same XX amount of fuel more efficiently than the 175cc, because of its bigger size, thus more umff to ignite the fuel. I know that the 190 can pump more fuel into the cylinder but talking about Xcc amount of fuel with in both capabilities of the injectors.

Thanks

I would say unless the nozzles were designed for greater efficiency, that the 190's would do worse.

Injectors put fuel into the cylinders, they don't ignite it. A 190 will put more fuel than a 175.

Isnt the heat of the cylinder and the quick compression of the fuel by the injector is what gets the fuel to burn?

It's the heat of compression (by the piston) that ignites the fuel.


Injector atomizes a set amount of fuel into combustion chamber, that's it. As the piston moves up and the intake valves close on the compression stroke, great amounts of heat are created, THIS causes combustion, and then the powerstroke .........exhaust stroke........... then it starts over with intake stroke, compression, power....yadda yadda

It's suck, squeeze, bang, blow! that's how life works haha.


Injectors play an important role in the process, as they add the fuel and, hopefully, atomize it correctly. Incorrect or insuficient atomization and you will lose power, run hot EGT's, smoke, ect


Is your original question answered now?

[smokersteve]

will the 190 disperse the fuel better than the 175?

I too had the same question and so far, I am going with the 175s. With the 190s your tuner will have to write a tune to basically defuel your 190s. No point in paying for something you won't/can't use. Kinda like buying a drag car as a daily driver. Now don't get me wrong, there are lots of people on here that run 190s with the powermax and are very happy. So it is just a personal preference.

All other factors being equal, NO.

Atomization should be the same, the 190 is just capable of injecting more fuel.

What is going to change atomization is the nozzles not the size of the injector. Example: 6 hole injectors vs. 8 hole injectors

Does full force have 8?
