SC Pulley Sizes
There seems to be some confusions when referring to various SC pulley sizes. I want to propose a naming convention to help identify what people are running.
There are two pulleys used and that can be changed; the dual alternator pulley and the SC pulley. I say we clarify this by adding ALT or SC on the end of pulley size statement. This is assuming the accessory belt portion of the alternator pulley is unchanged which it should be. Here are the one's I know of so far:
3.0ALT - Base SC Kit Alternator Pulley
3.275ALT - What is commonly referred to as the HBP.
3.8SC - Base SC Kit SC Pulley
3.5SC - The First Pulley I Had Made
3.3SC - My Current SC Pulley
I am currently running a combination of the 3.275ALT and the 3.3SC which yields about 8 PSI mean or nearly 9 PSI peak.
Running the 3.275ALT and the 3.8SC yields about 5.5 PSI boost, etc.

The Payn Tech pulley that I nick-named the Max pulley, would be a 3.55ALT, and would not be used with an SC pulley change, but did need the next size belt. The other size they made was a copy of the HBP, or a 3.275ALT.

The weather, and fishing, on the big lake has been cooperative so far. The mechanicals are squared away, and the electronics are next. It's great to be back on the water. Don't wait too long to get back at it!
Nice job with all the Hope Systems projects!
