Turbo Sizing and CFM difference???
 

okay, lets say i have a T3/T4 50 trim turbo, boosting 8psi... it flows a good amount of cfm cuz of the size of the turbo, probably enough for a stock LS to handle maybe? with my uber and dsm 450's, wat if i have a little T3 turbo off a saab, maybe the 42/48 or maybe even a little smaller. how much psi can i boost to equal the same or close to the same cfm as the t3/t4.

it seems kinda mathmatic calculating... but i can't really figure out the differences to be safe, i wanna boost as much as i can outta the small t3 but still sit at a safe level, im boost 9psi right now and it feels good as hell but i kno i want more, i kno stock map can't handle more then 12 and i kinda wanted to boost that but dont wanna exceed more then say a t3/t4 at 8psi's cfm, can anyone clue me in a little on the cfm difference or cfm calculations...?

If you compare the compressor maps for the turbos, you should be able to get a good idea of how they compare to each other...go to turbo calculator.com they have alot of maps there that you can look through.
