graham supercharger

does anyone know of the value of a graham supercharger...its just the main center part...no attachments but i think i came up with a way it could work on my flathead...i can get it in a load of stuff thats including a complete 49 flathead and a clean 59AB block along with a bunch of other parts for 300bucks...so if anyone knows about these superchargers please let me know

thanks alot
zach

 

ok i found a few pics of them in the dry lakes and drag strips book....anyone know the value?....im thinking i can make it work either on the v8 or 4 banger....

thanks
zach

 

Zach, GET IT, once you have it you can find a use for it! I'll look through some old 1950's Hot Rod magazines tonite, think I remember one on the cover with a flathead.

 

I just sold two with all the attachments manifolds for 300

 

37, i'll have to look through mine when i get a chance...if you find anything please let me know...sitting down thinking i think i figured out a way to make it work already though

hemi,
do you have any pictures of the ones you had with attachments..so i can get ideas of how it might work out...did you ever run them...how did they perform...truthfully i donlt care if it makes a big difference...just so it doesn;t hinder the performane...i just think it would look wild on there...and if not i could save it for whenever i build a salt flats car with a 4banger..either way if it works its not for sale but its nice to know what something is worth

thanks
zach

 

they mounted on the left side of the block,returns the oil straight back to the pan, its also where you added engine oil) pressure fed oil to the top and bottom bearings on the charger. driven off the back of the generator that spun at a two to one ratio,(so if you rig it up direct it spins half speed) the bottom gear in the charger runs at five to one, at 3000 rpm that old maytag looking*****er is spinning 30,000 rpm. I've read they were capable of 5-7 lbs boost. designed for the altitude of the rocky mountains.
there is a aluminum water cooled top cover on the impeller, and a water cooled aluminum manifold that crossed over to the right side of the block and bolted to the stock intake manifold. i'll see if I still have photos

 

wow 5-7lbs boost that would be plenty for a flathead....could probably run milled stock heads instead of high compression heads...in order not to pre detonate on pump gas...i guess i could rig up a water injector along with it to help out with that and to cool it a little so i donlt burn pistons...hmm...all these ideas...i guess if your pumping alot of pressure in you don't want to predetonate cause that would really kill the piston if its on the way up and all that pressure fires?...i might think too much!!....if you have pictures that would be great...

thanks
