What does he mean....used for racing "WHEN" VW's were popular....

Anyway I was confused because it looks like those things are shafts sticking through the carb manifolds????

While I'm not actually qualified to comment on this, my feeling is that this is some sort of Hilllborn type induction. Ya see injector bosses (not electric type) and butterflys and a place for linkage.

Yes! My thoughts exactly! With butterflies in the intake manifold I knew it must be something like that! Hilborn came to mind, but I have no clue how it works, just know it's old.

Well, only found a little info on EVM injection, this guys has it on his "Midget Pogo" race car:

The guy selling these things has some sprint car stuff too, so it must be some sort of racing setup? Oh well, I bid on them, they're just obscure and useless enough to be desirable in my eyes!

Interesting, seems these old systems used fuel pumps mechanically linked to the engine to provide variable pressure according to engine RPM's? Mechanically metered fuel delivery instead of air-flow controlled like K-Jet/CIS? The coolest part would be some honking chrome velocity stacks mounted on there!

Again, I'm not quite sure but that style uses reverse jetting. So you run a mech pump (cogged drive) and use pills to restrict the return line. The injectors I think are spray nozzles (like CIS). So RPM = Fuel spray, adjustments are made down stream by volume.
Cool stuff.

It sounds more similar in delivery to Bosch high pressure injection. Does it use restrictor pills like Hilborn? Or is the pump timed and pulsed like Bosch? Ray

Hard to tell based on just the manifold. But pulsed no, constant stream. I don't think it was common to time this style fuel systems (ie no fuel distributer). Has anyone asked Marc?
