i need some help getting info on a blower it has been fully rebuilt with no tags on it but i need to know the era and who made it, i have not seen it in person my dad is the one that bought it for me back in california and i am off at school in kansas. the guy that my dad bought it from had a scot blower next to it and it was about the same size i just need to know size, make, and era. the end pulley was changed by the guy who used it, but he gave my dad the original 3 groove V belt pulley that was on it.
i forgot to mention the script on the side once zoomed in says "IML" then there is a rib and then "LT"
With the straight rotors, I'm guessing it was an industrial blower. There are tons of companys that build/built blowers for forges, air management and other industrial applications. edit: Are you sure that dosen't say INLET. If the bearings will opperate at engine rpm's I see no reason why it wouldn't work in an automotive application. The straight rotors may induce some pulsation of the intake charge.
the guy told my dad that he thought it was off of a tank or something like that. he used it on his old drag car for years but had no idea what it came off of
I agree with OldTin. Most of the purpose built engine superchargers are well enough known to Rodders to be instantly recognisable. But many strange industrial air blowers have come and gone over the years which might be difficult or impossible to identify or get parts for.
well i got lucky enough to find one that was rebuilt already back in the 70s or so the old owner said. it is all there and he even found the old v groove pulley that was on it. i just need to know a general era for it i am building a 40s correct 32 roadster and i need to know if i need to change the era to run this thing or not. i have a 346 cadillac flathead that would be using this blower.
Interesting item. The similar Detroit Diesel blowers were in wide use in WWII and earlier, I don't know when they were 1st forced into use as superchargers. The 40's would seem reasonable. I'll be interested to see what the experts say...
These blowers have been around since 1860 long before even the gasoline engine. http://en.wikipedia.org/wiki/Roots_type_supercharger No real way of knowing when this particular one was made. What dates it to an observer would probably be the drive system and carb. A couple of 97's and some Vee belts and it will look about the right age.
i got just 2 more pictures today and a number. it does say inlet and on the side there is a 12579 number which is most likely the cast number.
I've seen blowers like that before with a couple of side draft Webers up top and a chain drive with a cover... Must have been in an old car mag from the early '60's...
