2 of them would be 1150 and my stock tb doesn't even flow that much so I think they would be plenty! Just think if you can go like 20+psi on a 3.8 with one of them and 2 on a 5.7 at 4.5-5psi should be plenty...Well at least it sounds right to me lol. Thanks for the flow #'s!
EDIT: I forgot to add that I'm only gonna be reving it to like 5500 anyway so it's nothing crazy.
