If you put a piece of paper on the intake side of a fan, it creates suction such that the paper sticks to the fan.. You also will notice the motor is working harder to spin the blades, and the blades will slow down. By blocking the intake of the turbo, you will create a large amount of suction between the "block" and the impeller. It will not spin freely, even though the exhaust gasses are pushing on it. You do have the oil lines hooked up, right? :) Why not just hook up the turbos with a short pipe where the intercooler will be going? --- Martin Gutkowski - DMC Ltd <martin@xxxxxxxxxxxxxx> wrote: > Why?
