Re: ---- YO CATCHCAN NWS (o)(o)
Coming from an N/A back ground with V8's this topic has been discussed plenty with the majority of engine builders and back yard hacks such as myself believing it won't even have a snowballs chance in hell of doing much but making you feel better.
A guy I race with has your standard 850 horsepower big block chevy in his race car. On an engine dyno when the motor was fresh the vacuum pump (good $500 one not elec. garbage) was good for no extra power. At the end of a long season they re dynoed the motor with and without the vac. pump and without the pump motor was down 30 horses, put the pump back on and it came right back. to where it was at the beginning of a season.
Not sure what point I was trying to make here anymore so ---- it.

FWIW my car has gone no faster now without a power steering pump than it did with one, so they might rob some power, but its single digit amounts of power that isn't going to add up to anything noticeable.

So why are you still running a pcv valve? I would think it would be best to run this setup with the line from the black box being "T'd" with the line from the vc and then ran to an oil seperator and then to the vacuum pump. either way good write-up with useful info

It will only be on in boost, thats what the hobbs switch is for.
I didn't want the pump to be running the whole time.
Plus I wasn't worried about blow buy Na.
