Like i said b4.. he was right.. sort of.
simple
all u gotta do is go through the bullshit he said and u will find truth in what he says, but to simple say, adding another turbo wont make power is the stupidest thing to say because if it was true.. then no1 would twin turbo any kind of engine
a single turbo can only do so much, do much less than what an engine can swallow, thats y ppl run bigger turbos and make more power with the same psi/boost/pressure.
my rotor made 240rwkw on 8psi.. single turbo... a stock gtr wont make 240rwkw on 8psi... with upgraded turbos u can. Flow is the key.. not just psi.
psi only gets u so far, Volume/flow is the only way to make power.
