Re: Rubicon injectors
Ahh, that's where I saw it I guess. Thanks.
The fallacy of the Mustang injectors is they give more fuel, but the ECM just shortens the open time - no gain. But - Matched Mustang injectors are available all over.
Getting all injectors to have the same flow rate can really help if they were off to begin with - you never know till you match them up. Since the computer only "sees" the average O2, unmatched injectors can cause some cylinders to be too lean while others are too rich, affecting power and mileage. The "average" is right, but none are where they should be. Getting them all pulling together can make a big difference.
Yes, airbox is gone - now a straight through with a K&N. It's not a huge difference, but you can feel it - so that means at least 4 hp gain, below that you can't "feel" it.
Rumor is they are noisey -- you can hear it, but not very well.
Small Throttle body spacer goes in this afternoon, supposed to add another 3-5 hp.
Watch out about the spacers - some are promoted as having a helix bore. The helix swirl cut works on carburetors and throttle body injection where fuel is intoduced into the swirling air, but not on port fuel injection. On PFI the swirling actually can slow down/restrict airflow.
Anybody know who has direct replacement "matched" 4.0's?
