Leads me to question I've pondered since i started my tunnel ram journey: Does lower compression affect intake air speed? Not wanting to hijack this thread but, I've read and been told that I would need to reduce my idle feed restrictors from .033 to .028 or so. I found by doing that it would go stupid lean (17+ AFR) in the transition slot area. Curious if that is due to the lower compression, in my case being exactly unknown but in no circumstance more than 10:1 causing lower air speed thus causing a lean condition. Where as when using a larger IFR compensates for the lack of air speed with more fuel being available. Am i making any sense at all?I hear these run so rich, etc, but mine runs well and gets good mileage,
