Setting up carbs help

[thom]

So I'm setting up carbs for turbo and was just wondering what am I supposed to do with this? It goes to plenum?

I asked the same question, in the "1100M engine to be wizzy popped" thread in the turbo section.

So did you get any clear answers or did I miss something? If I understood you are using 40's carbs and they also need to be drilled somehow. Mine are 38's but they look exactly like the 40's. no need for drilling here? Feeling like a retard here, but these two questions still baffle me.. and probably missing or confusing some thecnical terms since english isn't my native language. Somebody gotta hold my hand and guide me through this

Block the openings for the vent tube you have shown, and drill the hole from under the diaphragm to the air filter side of the carb. 6mm diameter should do the trick.
Using that tube to pressurise downside of the diaphragm is not the best way (more possible boost leaks) and you would need to reinforche that rubber T piece.

The 38's are slightly smaller versions of the 40's, but basically the same carbs.

so do I block just that T-piece opening or every opening from every carb? And still not quite sure what am I exactly drilling. Anybody got a pic of this done or can you draw something up? Thanks for both of your help so far. Don't lose your nerves with me
