Ok I was just thinking about this.

With so many modern and older vehicles using vacuum-operated accessories, what do you do with these accessories when you turbo or supercharge an engine? Do you lost them all together? Or is there a way to maintain vacuum?

Justa wonderin'...

Won't affect them as most of them are something you don't use under WOT conditions, like brakes for instance. EGR sensor inputs that use vacuum are ignored by the computer under heavy acceleration too.

 

Ahh good to know. Thanks for answering that!

Also, in my application I continue to have [some] vacuum behind the rotors in all but the highest boost ranges.
