Hey i had an idea of making my own custom supercharger kit for my car for under $200. I got a place where i can buy a used, and cleaned super housing and an impeller, but i have to make my own imput shafts and stuff, witch i can do but i need ball bearings that can handle 45,000rpm at the max.

Also the shafts would be a 1/2" and a 3/4" shafts if that helps.

Im just looking for ideas if you think these could be found relitivly easy on the net or if most bearings could handle it.

 

I was on a mustang coral board a few weeks ago looking for a Vortech for my Camaro and came across a post for bearing to re-build a Vortech. The guy didn't have any places to get the bearings, but here are some part #'s you could search for & may be find someone who sells them. Nachi ball bearings NAC-6003, ans SKF ball bearings 6205/C3. If you find any one let me know also.

 

I don't think your going to be able to get the impeller to spin fast enough. Most blowers have some kind of a gear mulitplication inside the case.

 

umm i can get the rps, 6" pully on the crank, 2" on the input shaft, a 3.5in v-pully, and then finnaly a 1.75" v-pully, i still dont get 45,000 but i do get over 30,000 close to red line, and i did find my bearings, and hopefully i can get some flow test done and find out the exact ratio i need for only 7psi, DONT WANT MORE LOL. Stupid stock 2,8.

 

I found some roller bearings in the MSC catolog on like page 3514, the 12mm-15mm iner bearings take like 30,000 rpm open, and about 26,000rpm with a shield, still not really good enough for a hi pro vortech but at $8-$12 each not too bad.
