The poor low speed performance he mentions makes my theory or dumping more fuel than can be properly burned is feasible.J572 had the dual carburetor blower but was pushing a lot of fuel into a small area normally serviced by a single down draft unit.

Many thanks for that answer. It's exactly the sort of information I was looking for. Your information on the Petersen's car is invaluable.
The last thing I want to do is to misinform my audience.
I'll try to get in touch with Randy.
Thanks again for your answer, and your patience with a long-time Duesenberg enthusiast and new ACD Club member.

The Petersen's car was not supercharged originally, but when it was restored it was upgraded, as many were in the 1980s, with a reproduction blower and the ram's head manifolds.
Most surviving SJs now have reproduction blowers, even the cars that were blown originally, and most of the reproduction systems are the "hotter" dual-carb version.
Good luck with the exhibit. I look forward to visiting the museum once renovations are complete.

In the world of Duesenberg one has to be specific as to chassis/engine numbers or things get confused very quickly. Hell it's confusing enough even when you have all the details! If you want to properly inform others as to the answer to your question then you really need a specific list of cars with numbers and body styles. Generalities and guesses just lead to the propagation of more Duesenberg misinformation.
That's my $.02!

I am a newbie on this board and chassis and engine numbers are Greek to me.
My purpose in posting was to have a basis upon which to state how rare the Petersen's 1933 Murphy Convertible Coupe is.
If anyone knows the chassis or engine number of those I have mentioned, that would help:
The Petersen's 1933 Murphy Convertible Coupe.
The 1933 Murphy Roadster (Chassis 235?) in the Central Texas Museum of Automotive History in Rosanky, Texas.
The 1933 SJ Brunn Riviera Convertible Sedan shown last summer at Pebble Beach.
The 1934 Rollston Limousine shown last summer at Pebble Beach.
The Mormon Meteor?
Meanwhile, it looks as though my initial guess of "a handful" is pretty close.
Thanks again for making the effort.

I am familiar with SJ528 as an unsupercharged car and the owner of record in 1951 told me he had the blower for it.I remember seeing it when we delivered the remains of J467 to him in late 1953. I have also heard there were six dual carburetor superchargers made but have no way no verify it.

I am preparing a presentation on Duesenbergs for the Pit Crew at the Petersen.
Various sources say there were 36 or 37 supercharged Js (and several were retrofitted), but none mention how many were built with the supercharger and the dual carburetor "Ram's Horn" manifold, like our car.
I understand there is one in a Museum in Texas, and I presume the Mormon Meteor was another. I saw that the 1334 Rollston Limousine and the 1933 SJ Brunn Riviera Convertible Sedan that appeared in the Pebble Beach Concours d'Elegance last August both had it.
That makes five. Does anyone know about any others?
