What size nozzles

[kdogg85]

I am going to run 350cc injectors in my truck, getting closer little by little.

Any way, would 125's or 150's be the ticket? An explanation for the suggestion as well would be appreciated.

Thanks in advance

Saw some math used to figure this out.

stock 135cc


so 350cc-135cc=215cc larger

now 215/135=1.59
so roughly 150% larger is needed to empty the injector.

I would suggest 150% nozzles as well unless you want to run crazy timing to dump a smaller nozzle. Based on what I've seen with flow benching a 100% nozzle, we were getting about 95-98cc/ms in a 1000 shots at 4000 psi of ICP. Haven't done much with the 150s yet but based on the math you should be able to dump a 350mm^3 body in the 2.5 range ms of PW as long as something else in the injector doesn't hold you back. Best of luck either way ya go man.
