Does anyone know if any MGBGTs(racing or stock) ever came from the factory with A Roots Supercharger? Any information on this subject would be helpful. I am currently considering buying a 1967 MGBGT

goings-on on a car made before January 1, 1968. After that... It was not a factory option to my knowledge or every autocrosser would have had one, believe me.

I think I can say with a fair degree of confidence that its not a standard mod and I've never heard of a special like you decribe. If it was some kind of factory special then there ought to be at lea

Let me guess: The air first goes through the three carbs. Then through the Roots blower, which is connected to the B cylinder head via a manifold similar to the one used to put one large SU on a B. B

Well, you certainly couldn't presurize an SU and have it work, so that sounds reasonable. But 3 carbs? All the supercharged installations I can recall only have 1! (well, maybe 2, but not 3) You get

A pressurized SU or Stromberg would require the area above the diaphragm to be pressurized as well as the float bowls...
