Hey Bob, well, all I can really comment on is what is currently a production FAI engine, ie: what I can actually buy as your average joe speed freak. That is the Nelson, and the JETT, and even the BSE JETT is front intake. So is this MB Profi FAI engine.


I have no clue what JETT or Nelson have in the works, I know Nelson used to have a rear intake FAI engine in the early 90's but it evolved into the front intake engine. The Profi went from front intake to rear and back to front again. I wonder if the rear intake makes it to hard to get the required amount of air into the engine? So anyway, I only pointed out the intake location since you mentioned current FAI engines, and from what I can see, all the current and available FAI engines are front intake
