I was wondering if anyone around here has or knows of anyone who has put a supercharger or a turbocharger onto a big inch Cadillac engine? What kind of power would we be looking at there? If you were to supercharge a 1970 500ci what kind of horsepower would it be?
go to www.procharger.com it has exellent supercharging systems with intercooler kits.they come with warranties and detailed installation instructions...if i had the money i would buy a kit for sure.they are also 50 state carb legal.i have not even heard of anything close to these kinds of offers,usually there is alot of risk,but this company gives u a lot of "peice of mind" and is a "safer"bet than most other "systems"....

Re: 472 or 500 Superchargers?
There are a couple turbo 500 projects out there, there are 2 people over at shiftless's forum who are actively working on their projects but neither are quite done yet. When I get the money I'm going for two big T04s or a huge single on a stock or near stock 500.
b-m no longer makes blowers ..... holley took weind and b-m and put them under its own name ........ since the adaptor was for the b-m case and holley went with the weind case the part went away ...... I tryed to get some before this happened but was too late ...... the adaptor with the 177 blower has run well it took a stock 8 to 1 motor from 273 hp and 447 ft lbs to the rear up to 384 hp and 520 ft lbs to the rear with 7 lbs of boost the blower can make 9 lbs on a 500 cid motor ......... the blower setup was for a pontiac motor and was used when I got it ....... b-m made lots of the adaptors so they are out there if you look but you will need the b-m blower to bolt to one ... or you could make a new adaptor for the holley blower ......... these types of blowers are also avalble from holley in a 250 cid size that would let you run more boost....... your other option for mounting the blower is a potter intake with a new top plate .....
Sinverarity has about the best suggestion. get an adaptor plate for a BBF 460 and Weiand makes a kick but supercharger. put dual 4bbl and a couple Hi-Tek filter assemblies, and nice seeing you... you're gone.
Saw a couple of turbos on Caddy Big Blocks this past weekend at Potters Shindig in Chattanooga, TN. Maliboo had 1147HP out of a twin turbo Caddy Big Block in a highly modified and custom Malibu. Purple inside and outside and wicked as hades. Sean brought his 1969 Coupe down from Ohio and it was One Bad Cad with a turbo. It was set up for drag racing and he had just made his first pass a day or two before the trip. It looked evil, kinda like the Lincon the cut up in Animal House. I told him he needed a skull and crossbones painted on the body somewhere. It was a Hoss for sure. I would have loved to see them line up out on the 4 lane, but cooler heads prevailed. It can be done if you have the time, patience, and the bucks. Oh yeah, some big ole nuggets might come in handy also.
I don't really think the nuggets have much to do with it! More like dane bamage to light the candle on something with that much tourqe and horsepower. I think the ole nuggets might draw up and hide if I ever got a chance to drive one of those beasts. I know the pucker factor would at least go up a few notches. I think I have lost egnought brain cells over the years to give it a try, but my better half might want to make sure the the ole life insurance is paid up just in case
