i've been thinking about going to a turbo set up lately so i've been doing the research. i've gone through garrett's turbo intro tutorials, and from what i understand, it's for single turbo's.
what i need to know is how to select twins. do i just need to split the airflow capacity in half? i'm pretty sure the pressure output would stay the same since they're pushing the same amount of boost.
do i have this right or am i way off base here? i'm pretty new to turbos, and i'm trying to learn as much as i can before i actually do it.
