FWIW, if you're using a speed density EFI system, it's recommended to have all the cylinders tied together one way or another. The guys who are doing speed density EFI systems with Hilborn or other type individual throttle bodies generally still tie all the cylinders together, even with something small like a 1/2" hose in order to get a decent MAP reading. I guess if you were using an EFI system that used a mass air flow sensor instead of a map sensor you could get away without it.


Well, using a MAF would tie them to a common point as well, the MAF sensor does need to measure all the air flow.


yes but you could do that before the throttle bodies so your tie in point could be complete separate from your intake manifold. Alternatively I wonder if you could put a MAF on just one cylinder and tune assuming equal air/fuel flow to all cylinders.
