Hot Rods Flathead Roots Style Blower

Just spotted this in an ad on another site.Anyone here have any info on this Marshall Supercharger? Looks like the Scot.

 

I never heard of the Marshall so I Googled it, it was designed as a cabin blower for aircraft. To go to higher altitudes a Roots, or centrifugal type was used to pressurize the cabin, but that’s not to say it couldn’t be adapted to a small V8.

 

Does seem odd to call a plane cabin pressure pump a supercharger.

Fordors is correct.I should have Googled (Godfrey Marshall Superchargers)it before I started this thread.They were made as cabin blowers for civil aircraft.The seller is in Switzerland and wants $3550 for it.

 

Why not just buy a Weiand 144?

 

Because he's a Hot Rodder.

 

Yuck!

When a friend of mine would see one of them on a car he would say "they're just like a blower, only smaller".
And he was being polite!

 

$3550????? Why not use a Wade RO34 .

 

On the other hand the GMC based items many hot rodders call “superchargers” were actually blowers. When the Roots brothers invented their blower it was made to ventilate mines, and the GMC’s were used on two-cycle diesels that needed help to help get the exhaust out of the cylinders.
