Thread: Z7 Turbo Kit and proper boost

so either, dont know how a wastegate works, or you never seen a good setup.

the waste gate will have a set pressure where it will open. and it wont open until you hit that pressure. so your wastegate wont open until you hit full boost. not just starting to boost. my current DD runs a 15 psi wastegate. so if I run the line from the intake straight to the wastegate, my boost gauge will read 15 psi til redline, or I up the boost with the controller.


Oh and im totally gonna get flamed for this I know, but you DO NOT TURBO A GRAND PRIX TO BE FAST. you turbo one for more power, or better gas mileage, to be unique, or because you have nothing better to do. but it will NEVER BE FAST.

How do you figure that? A basic turbo setup on a grand prix and that grand prix will run high 12's. If you.aren't trapping 110+ in a 1/4 on a turbo setup your doing something wrong.

A wastegate also doesn't tell when your turbo is the most efficient. Usually run a smaller spring to start tuning and then raise the boost via boost controller.
