Man i don't know how that would work with a blower motor. I don't know the answer :? i'm just posing the :?: I know for sure the tank would not be big enough. I personally run 2 burn down tubes which are 1 1/4" in dia. mounted on the top front of the valve covers and running to a 1 gal. tank in front of the motor. There for sure is a lot of pressure in the crank crankcase with a blower motor, especially when you're running 20 to 40 lbs. of boost. I don't know if a vacuum pump could keep up with the pressure, and i run total seals best rings for blown and or nitrous, again i don't know. I know i've never seen a vacuum pump on any of the blown alcohol or nitro cars.
