whats the difference between a procharger and sc. it the procharger just cintrifical or what.

 

Procharger is the name brand of a centrifugal S/C.

 

are they a good brand?

 

Yes they are a great brand, but they are self lubricated which I think kina stinks. You have to remove the whole damn head unit anytime you wanna change the oil (every 6k miles). Id rather have the constant fresh supply of oil from my pan like Vortech uses.

 

how muck boost do they normally put out? sorry for all the questions

 

depends on the kit. some are 5-6psi. some are 20psi kits

 

when you put on avortech how much extra oil do you have to put in?

 

Prochargers usually come air to air intercooled with 8 psi.
