Alright, so i Got the rx1 motor running in my sled right now with just the primary on it, as its not quite ready to be snow/grass dragged to do any final testing.
I have the carbs all boost referenced the way there supposed to be, my fuel reference is off the nipples onthe carb boots all tied together, when i hammer on the thing and it builds boost, approx 8-9k the thing lean pops really bad and my afr gauge goes --- red.... its SUPER lean, First thoughts were that it is jetted way lean, then i thought for it to be gettng that bad, and only under boost would that suggest that my boost lines that T together for fuel pressure might have a leak in them, i need to go take a picture and check my boost vs fuel pressure as they both jump up, to make sure there increasing properly.
also, the spring thats in the fuel pressure regulator is a slightly different one that came in it, guy before me played with it and Im thinkin its stiffer, but that should not affect anything but my opening pressure base pressure yes? then the boost does the rising. just all thoughts on it.. gonna go check some stuff. i have all 4 of the nipples in a big T- situation and am wondering if that is leaking some and causing it to lean out, as my wastegate is set at 10psi and im only seeing 8 on my boost gauge which is t'd into the fuel system setup...
