Precision vs. RC injectors question
There is a huge price difference between the 2 brands, with RC being almost double the price.
Is there a huge difference in quality/fittment/reliability between the two?
I need 440cc injectors in the next 3 weeks. I want to go with Precision to save $$$. Can anyone tell me their experience with Precision injectors? Are they a safe choice?
thx

Re: Precision vs. RC injectors question
Both can provide what you need. The Precision uses a Delphi Injector as its standard, and you can even get up to 525cc high impedence. The RC injector typically is a Rochester/Lucas injector. They work good as well.
Can't go wrong with either one, but the Delphi / Precision is a nicer choice from my experience.

Re: Precision vs. RC injectors question
i am not a tuner, so my experience may be user error. i had the Precision 650cc hi imp injectors and could not get them idle very well without being almost 12:1 AFR. switched to the RC 750cc hi imp and now it idles 14-15:1 no problem. i also could not get my battery offsets right with the precision, but the RC was pretty easy.
i believe the Precision 650cc injectors were Siemens, so that may be part of it too. i'm sure both are just as equal in the hands of a real tuner, but that was my experience with the two.

From what I have found out the RC's have a better spray pattern and atomized better because of it. Just more engineering and research in my opinion.

Re: Precision vs. RC injectors question
Do you get better atomization from one over the other given that fuel pressure remains at the same setting?
