@Stovebolt , I am helping out a friend with a Wade blower. If yours pictures is a 34 then would you know if this unit is a 20? We are trying to get as much info as we can for this install on a stock flatty. Hard to find any tech on these old blowers.
@vtwhead somewhere I have some files on rebuilding a RO34 blower 34 = 3400cc air per revolution. I would have thought a RO20 is a bit small for a flathead - unless it is a v860.
that is so beautiful that i'm not going to worry about bearings in the gen having a hard life!-wow,nice...
I doubt you'd have enough room under the hood for the size pulley you'd need to spin the compressor side of a turbo to make any significant boost. The old McC and Paxtons had a ball drive planetary system that drove the impeller many times the input shaft speed. Craig Conley (Paradise Wheels) in San Diego owns the rights to the ball drive blowers now and can rebuild or supply parts. https://paradisewheels.biz/super-chargers Here is a Judson I had on a Nash Metro - I think it was a 1200cc what's that about 75 cu in. You'd need 3-4 of them.
Hello, Here is what we thought was the ultimate for our Model A coupe purchase… an SBC motor with a Paxton Centrifugal Supercharger. There were other superchargers on the drag racing scene and just down the street from our house was a large dealer that sold trucks and freighter trailers for the vast harbor transportation system. In that particular shop were floor models of any diesel motor with 671 GMC superchargers. The 671 superchargers were for the large drag racing motors of all kinds. Not one was used for the street until into the early 60s from the drag racers who used the extra power to win in the street legal Gas Coupes and Sedan classes. It was also a mainstay in the popular street roadster classes as they, too were street legal builds. But, when we started, we saw plenty of supercharged motors in the early Ford Thunderbirds and other cars. By the time the stock Studebaker coupes came out to try and rival the Thunderbirds, folks were using the Paxton version of the centrifugal supercharger for extra power on the street and at the drags. When a hot rod came into the local drive-in restaurant parking lot and it made a whizzing noise, everyone knew it was a “centrifugal supercharger.” There was no way to hide that fact. There are a lot of 671 superchargers on the street today. they are adjusted to run easily with the high performance motors. But, the movement for daily drivers with 671-471-371 superchargers was not a street thing to do unless one took out the vanes, back then. Jnaki The best example of the first powerful SBC motor with a Paxton style supercharger was the 41 Studebaker Sedan of Junior Thompson. It was put together in a small shop near our own Westside of Long Beach house by the owners of the Speed Engineering business. Tom McEwen and Ronnie LeGrand opened the shop and were well known racers from the Bixby Knolls Area. Note: Then, one day, a custom speed shop was opened, a few blocks from our last Westside of Long Beach house. It was in the industrial area near the Los Angeles River and PCH. The shop was called "Speed Engineering." Besides winning a lot of trophies at Lion’s Dragstrip for themselves, they helped build the fast 1941 Studebaker Sedan driven by Junior Thompson during this time. In 1959, we saw it at Lion’s Dragstrip almost weekly as they were at the Speed Engineering Shop to get some upgrades and race tune ups. The shop was in the same industrial neighborhood as Venolia Pistons, Clay Smith Cams and other speed shops in the race car world at the time. They even built several stock bodied Chevy sedans for the “stock” classes and then moved to the gas coupe and sedan classes with larger modified motors. As old time hot rod/drag race events are supplemented with tons of history and stories that have a life of their own, this was legendary. Then finally, as advertisements came out with is 57 Chevy, front and center, Tom McEwen no longer could say the Chevy Sedan(s) was/were stock. So, the designation of D/Gas was on the 57 Chevy Sedan. Even that was questionable as what else was inside that supposedly stock 283 motor? Perhaps a Reath Automotive Stroker kit, plus a bore to make it a 352 cubic inches? Actually moving him to B/Gas status? Ha! Then the sponsors rolled right into the picture and the rest is noted history from Bixby Knolls. YRMV But, they could not be wrong could they?
nice set up. i assume no hood blister required in the '40. any chance someone would have a photo of the mounting bracket for this style supercharger? i am not familiar with it so have a bit of trouble 'filling in the blanks." thanks, sid
No hood blister required. Check this thread out for more bracket details. https://www.jalopyjournal.com/forum...-57-supercharger.1251165/page-2#post-15536818
thank you. there seems to be a lot there to absorb, but when i attempt, there will probably be more questions . . . .
