the tri power setup. and first testing 

You need to feed the carbs into a plenum that hast the combined area of all 3 carbs.. Trying to feed the super charger through a manifold that is too small limits the flow into the super charger. At this point you are better off with one carb.

Loving this

Very cool! 👍🏻

Badass!!!

supercharged VW, tri-power? Cool factor - maxed out.

Progressive would be the way to go

Your loosing flow speed on the venturi's
