Hello Mike
I heard that it was a good event.
As you say the twin SU carburettors are hanging off the front mounted blower
and those things are two blow-off valves that protect the supercharger from the
effects of backfiring.

Subject: [Healeys] Non Healey Question...Blower Bentley
?I was at the Ellerslie Intermarque Concours ?in Auckland last weekend and had
the opportunity to take a close look at a "1931 Blower Bentley".
There is a part of the engine that I cannot figure out and was wondering if
anyone on the list who can shed some light on this.

Where the carburetors would be mounted on a non supercharged engine there are
these very complicated devices.

I would guess that they are some sort of relief valve but, as the carbs are on
the blower inlet I don't think that is very likely.
Anyone know?
