Centrifugal supercharger brackets?

Would designing a bracket be a fairly straight forward affair or is this something where one could easily get in way over their head?

The brackets I am familar with are very very basic. You got a plate and some spacers that mate up with whatever holes in the front of the block you can get to. And long bolts, really long bolts.

yes the factory brackets that come with kits are nothing but a big fat flat aluminum plate with the blower pattern on one end and the pattern of whatever you want to bolt it to on the other, with tube spacers and long bolts.

Simplest plan of attack. Use what some like to call cad "cardboard aided design" the idea is you use thick paper, cardboard, coroplast, whatever and cut it into the shapes you need. Trim your "cardboard" until everything fits right then take it, trace it onto sheet metal or aluminum flat stock, and cut it out. Or heck if you didn't want to or have any tools whatever, take your cardboard brackets to a machine shop or even junior college vocational machine shop (usually free) and have them recreate the parts in metal. Either way you end up with parts that fit and you didn't scrap a bunch of metal to create them only some boxes or election signs.

Sounds easy enough. Next step would be belt routing I guess?

First put the blower on the engine such that it fits, then worry about routing the belt, although one must be mindful of course.

Belt alignment is one of those things that sounds easy, but is critical to a reliable setup.

I assume this part can quite wasily be messed up.

For what engine? Maybe a bracket already exist

Based on some of the results I've seen, I'd say it is quite easy to mess up . I've seen belts that seem to be just fine until you get on track, then they fly off when you start to run at higher rpm.

Start with the basic location viewed from the front and get your belt routing and wrap figured. Then the fore-aft part, which is the tough part. Belts are a bit weird, iirc a convex pulley will self-center which is the opposite of what you'd expect.

From what I've gleaned off superchargers and belts. Obviously location is most important the belt needs to be straight and not bend for or aft to meet the next pulley. The next important part is that the pulley is in contact with the belt for AT LEAST 180degrees otherwise belt slip in higher rpm is possibly if not guaranteed

I spent more time than I would like to admit doing custom brackets for a PS pump this weekend.

My advice is: buy a MIG, even if it's a cheapo used flux-only model, and some 3/4" X 1/8" and 1" x 1/8" mild steel angle.

Cut and drill one piece of steel so it bolts to the S/C in a mountable plane and another piece so it attaches sturdily to the motor in the same plane, touching on two flat surfaces. Position the S/C so it lines up in all three dimensions, and clamp the two pieces together. Spot weld. Repeat for one or two additional brackets.

Then finish weld those brackets, and road test. If they're good to go, paint, or take them to a better fabricator and ask them to duplicate them for you in a suitable material.
