Hey i'm new here and i have some basic beginner questions...

Do you guys brake boost when racing in a 911 turbo?

Are the twin turbos parallel or sequential?


And do people install boost controllers in 911s? If so what is the max psi you can go on a stock fuel system?



I'm planning to get a 911 turbo in the not-so-distant future and was wondering about this(im def gonna go aftermarket). Thank you for all the help.
