Auburn 852

Yes, superchargers are available.

On the left front top of the block there is a boss that sticks out with the engine number stamped in it. It should start with a GH. The identification plate on right outside of firewall should be 5 digits long and start with a 3 on a supercharged car.

Don't expect a appreciable increase in power from the supercharger unless you want to twist it to 3,000 or 4,000 RPM.

The Lycoming tag isn’t there anymore. The car tag mentiones a GH engine number and the drive shaft connection is still there on the timing case.

On the Lycoming tag on the right side of engine, does it have a GH or some other designation? On the left side the supercharger was driven of the timing case, is there a
A drive shaft protruding out?

Hi all,
First many thanks for accepting.
I’m from the Netherlands and a classic car enthousiast since I was a kid.
About 30 years ago a friend of mine bought a supercharged Auburn 852 of 1936 without knowing too much about it at that time.
First time out the performance was disappointing and when he lost a wheel, due to a missing cotter pin, the car was parked in a corner of his garage and stood there ever since.
After much talking and persuading attempts I convinced him that it’s a disgrace the car was neglected for 30 years, and that the car should be back on the road.
When opening the hood I spotted that the supercharger was missing and that is probably why the performance was low.
In general the car is in good condition and after inspection and servicing it will not be a big deal to get it running again.
But I have a few questions.
First, is the Schwitzer-Cummins supercharger available at part suppliers?
And if not, is there an alternative?
And second, is the compression ratio of 6.5 : 1 the same for supercharged and non supercharged cars ?
I can imagine that a supercharged engine maybe has lower compression ratio pistons than a non supercharged engine.
Help will be very much appreciated.
Thanks a lot!
