I am sizing up a unique 4cyl project. 108ci
the barrel for my singular barrel intake was for a thing called singular point fuel injection..can't use it anymore, going extinct like an earthquaking island. The intake is very nice, and the last year for the castings, a bit larger..kept it to revive an old engine...without a carb choice, except for a one barrell.
It is huge compared to the chevy vega monojet at 1 and 5/8ths inches...and found the next monojet that went to the 2.5 liter up to the 292 is a better match. The cams are bigger than the injected as well. I am guessing it can handle it.
my question is ...
can I use the smallest jet from this list on the bigger venturi?
my own guess is yes, as monojet should have been in the 30s mpg way back when, and they were not. leaning out is an option.
so... little main jet, bigger venturi? that is the question.
this is a boxer intake as well, so a centered 22 Hg of vacuum is there at all freaking times. no wobbly intake runner games with the weirdo inlines this particular monojet typically came from.
am going ahead regardless of answer, but am curious, maybe a beetle owner played around with this already.
