How much vacuum does an s4 na generate ? I want to use power thats available th redisgn the 6pi so I can remove just about everything and clean up the bay . On my T2 this was easy obviously . I dont want to buy a tire pump and redisgn that to make it less efficient. I do realize I need to use a switch as the s4 do not have any triggers (that have been noted ) Thanks

 

but why? and if youre so ambitious why not go grab a boost gauge and find out?

 

Why do I want to clean up my engine bay and redisgn the 6pi ? Or removing unnecessary emission related or accessory items that arent used ? Like aas os the optional windshield wiper reserve tank wiring on the driver side . I dont know , it looks better imo .
