Blowing Through an E4EM
« on: September 25, 2014, 02:38:39 PM »
Just rebuilt my E4ME carb using one of Cliff's kits and its like a new car, so thanks for putting out a good product. Of course I can never leave well enough alone and I am not contemplating the possibility of running a centrifugal supercharger on my freshly rebuild chevy 350. I know there are several over the counter blow through carbs out there that I could get, but I'm a masochist and like doing things the hard way. Anyway I'm planning on running no more than 6#s of boost.

So my question is can an E4ME be made to blow through?

I figure the main spots to seal properly will be around the accelerator pump, TPS, and idle screws. Am I correct in my thought that the bowl vents internally not externally? I also know I'll have to boost reference the mechanical fuel pump.

What other modifications am I missing to make this work?

I should also add that I plan to use a carb bonnet or hat not a pressure box.

Another thing I realized is the secondary air valves are vaccum operated by the choke pull off so some sort of mechanical solution would be needed there as well.

Considering the crickets chirping, maybe I'm barking up the wrong tree and should go with a made to order blow through carb from CSU or switch over to an add-on EFI system from Holley or the such.

My understanding is you have to lock in the secondaries on the base plate.  Which can be done by linking the secondary arm to the rod.  Otherwise, with pressure from turbo, they won't open.
