The short answer you seem to seek is, "36 supercharged cars and very, very few of them were dual-carb." Randy may be able to give more firm numbers.

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.

Chris:
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.

Again I will defer to Randy's wisdom but here is my recollection:

1. Mormon Meteor
2. SSJ #1
3. SSJ #2
4. Mormon Meteor Spare that allegedly ended up in J292.

Hello.To my knowledge their are build sheets by Duesenberg for 38 superchargers plus the prototype built by Duesenberg bros for a customers J. These SC were moved around by the factory in there period to 50 different cars. Today there are a number of reproductions built totaling roughly another 20 SC giving you atotal of 59. the dual carb cars were designed for flat out driving and were not real successful in traffic conditions and I would have to count these . The Rams horn was only used by the factory on three (3) cars the Duesenberg special and the 2 short wheelbase cars. R

What Randy says makes sense.The three cars he mentions are all later cars.
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.
