Default vacuum pump needed? if so what kind?

im looking for some advice on if I should be running a vacuum pump on my setup.
im pushing around 21 psi of boost, and making just under 900 rwhp. I currently am running a breather on a catch can with a -12 an line running from a valve cover. Im also running a cog drive for my blower and I have the alternator mounted where the ac is on a stock motor so i dont think theres anyway to make a belt driven pump fit in there. are there electric pumps available? thanks for everyones help in advance!!!

big ring gaps, 20+ psi of boost, a couple of guys in the area that are big supercharged racers suggested it. I have not put a vacuum gage on anything yet to test however

That would be the first step. Do you have any issues at the moment or are you trying to be proactive?

What do you mean you "get a little vapor out of the breather?"
