In fact I used a vacuum pump before they were for sale for crankcase evacuation.

With a vacuum pump you have less oil leaks and it does pick up horsepower. The horsepower is not that much and we throttle stop the engine anyway so a few horses is not a big deal.
I personally like the vacuum pump and recommend the Moroso units.
The crank trigger is nice but not sure of any major benefit other than it is easy to set the timing and does not move from the initial setting.

If you run methanol it also stops your oil from milking up
