I have the Renegade dual brackets on my 93 with a Si-trim. What's the best way to set the tension on the blower belt. I know I can just crank down, but is there a proper way to set the tension to avoided unneeded stress on the crank?

Best I've heard is setting the tension based on type of noise when you pluck the belt. I'm like you though, there should be a better way.

Interestingly enough, I've been studying the blower braces for this exact reason.

Buy yourself an inexpensive belt tension gauge - I bought a Krikit for less than $20:


Then datalog your passes until you find out how much tension you need to get rid of belt slip. Personally, I wasn't comfortable with the amount of tension I needed with my manual tensioner, so I built a spring tensioner setup - my required belt tension dropped from 180 lbs to 100 lbs. Here's the tensioner I built on the dyno:

Don't let the "professional" tell you large supercharger crank pulley and belt tension don't affect the crankshaft and bearings. At least on a standard mild application and kit.
I would suggest proper alignment, even/flat belt contact, traction pulley features, bracing, and large tensioner pulley. This also includes proper belt wrap on the DriveR and DriveN pulleys.
