I think Ron misread your post Frank. Ron, I think you misread Franks post
Frank just said a restriction is a restriction is a restriction.
I take that to mean that cylinder doesn't care as long as the mix is right. It could be a roots type restriction or a throttle plate. Throttle plate has been done
Something else is going to take some head scratching, but if there is a
bolt on for existing gas cars that can help close the efficiency gap with diesels, then it's definitely worth discussing.
