I really never had looked into buying a turbo or a supercharger for my 6 except I saw mustangaroos setup and saw the price. a couple questions what would you guys recommend? What do the stages determine? is it a specific number or anything? I enclosed a couple of pics of one just for an example. how would I go about mounting this turbo. I see 3? holes exhaust, intake and the spot where it connects to the carb right? could someone possibly diagram this for me? I will ty to find out more on turbos, also how much psi or CFM do you think a 200 could take (not to the point of detonation), I have seen some elctric ones on ebay that are only 200-250 cfm.... any help would be greatly appreciated!

Also here is the link to the turbo that goes with the pics

I'll give this a try... Sorry I can't open Ebay through these military computers so I can't comment on the turbos that you had listed. The CFM thing though I can help you out. Take the cid (200) divide it by 2 because it takes two turns of the crank to complet all 4 cycles for all 6 pistons. Times it by the rpm (5000) gives you 500,000 cubic inches per minute. Divide that by 1728 which is the amount of cubic inches in a cubic foot. You should end up with 290 CFM. Since only race motor near 100% VE, take 290 and get 80% of that. That should give you 230 CFM. If your trying to run say 15 lbs of boost you'll need 1.5 time the volume of air to do that. 7 lbs of boost takes 1.3 times the volume to do that. It's realy called density. To increase density you increase the pressure. 230 times 1.5 equals 345 CFM. Now if your motor has a larger cam and valves the VE % will be closer to 85 or 90% therefor would beable to pump more air easer. It will take more volume of air to make 15 lbs of boost. It's hard to look for turbos on like Ebay because you won't have a compressor map to look at. Some guys are running the turbos off of Buick GN on their 200's The GN turbos were ade for a 231 6 cylinder. If you can find a turbo with corisponding compressor and turbine A/R ratios you'll be in the ball park. There's a couple of good turbo books out there that are full of information on how and why turbo do what they do. Hope this helps some.
