Questions about fuel injectors

[russellb]

Aftermarket injectors: Has anyone used them? What kind of results did you see? Was the performance satisfactory?

42# injectors: Is it ok to upgrade to 42# injectors without upgrading the supercharger? Will the ECU adjust to the higher flowing injectors? There is a possibility that I may need to either clean my stock injectors of replace them. Since the 42# injectors appear to be available for a much better price than the stock injectors I have been considering going ahead and replacing mine with the higher flowing injectors. I may upgrade the supercharger in the future but probably not this year.

w/o more boost you will run pig rich. ratio is key. You oughta be able to find a used set of 38#'rs in the classified relatively easily...when those are swapped for 42's

Maybe I should just start with trying to get the stock injectors cleaned. I have seen one or two places online where you can send them in. I'm still down on power and rpm's on my RXT and it should not be the supercharger because it was just rebuilt. Hoses have been checked and are tight as well.

You could always go with the 42lb injectors and upgrade your SC with a new wheel. When is the last time is had a rebuild?

It was actually rebuilt on May 15th by you guys.

Ah perfect. Well if you decide to go the new wheel route you can send it back and we will install it free of charge.. :cheers:
