Twin Turbos PLUS !!!!

That butterfly up top has to be sealed off from the blower and it is only taking the place of air cleaners/air intake to the turbo's. The boost from the turbo's are going in under the butterfly deal.

In theory I don't think you would need blow off valves on the intake tract with a set up like that. Let off the throttle and all air is cut off from entering the turbo?

Also are the blow off valves hooked to the wrong side for vacuum to activate them? Shouldn't they be under the Carb butterflies for them to activate.?
