After seeing this video on youtube of a supercharged 327cu" Packard straight 8 rat rod I am thinking of how this could work on the Hudson eight.

He has used a McCulloch VS57 from the '50's which has its own oil supply and doesn't need pressure feed, feeding into two Stromberg carbs modified to take pressure. Max pressure is 5psi with this supercharger which is 2-speed. He's now rebuilding the engine to take 4 carbs and looking for 200rwhp. It does sound good too with his open header system. Judging by the tacho on some of his other videos he's taking it up to about 4,500 rpm.
The Paxton SN60 is similar in design (self-contained oil supply) and more modern with parts easier to come by.
The Hudson has quite a bit of space on the left front of the engine. The crank pulley and belt drive would be one of the main issues to resolve.
I wonder whether the Hudson engine is strong enough to take this? I think the Spikins special was supercharged and Brough did supercharge the 212 engine in his later Brough Superiors too (when he lost the right to use the H8 engine) using a Centric blower at 5-6psi. There's a road test of one in the Railton-Brough Superior Brooklands Portfolio Road Test book. The bottom end oil feed may need to be pressurised as Ivan has done if much cornering G-force is anticipated.
There is a good website dedicated to the McCulloch: http://www.vs57.com/
I have a rusty '36 Hudson Eight 64 sedan that I want use in some form of competition and thought that supercharging it would add a bit of interest to the project. I can either use the sedan body stripped out or use just the chassis and build a Railton Light Sports Tourer type body on top. If the latter it would go pretty well with say 175hp pulling 2000 lbs of car, plus driver. I'm not really interested in being constrained to any particular class and thus limited to period modifications so free to do what I want. "Run what you brung" is what I like whether hill-climb, sprint, vintage drag or whatever.
Given that it is difficult to modify the Hudson engine as far as bigger valves and compression are concerned supercharging seems logical. Hudson did say in the late 40's that as soon as 100 octane petrol became available that their 6 and 8 engines could be made to have 9.3:1 compression to suit.
Interested to hear if anyone has experience or has heard anything on this subject.
