If you look there are some 4500 to 4150 adapter that are only an inch. Some 4150 have baseplate to fit both
I think with it being for a dominator bc of the height of the sp1 + any adapter for a qjet it wouldn’t work with a gs 70-72 hood and air cleaner. Any thoughts?
Well it would provide a path to the dyno for me. Need a single plane intake. If thumper passes, I’ll take it.
