Anybody test the waters before and after? I'm sure the more power you make the more the boss intake helps, what about under 10 psi?
Probably could have done without on my full bolt on car but I already had the manifold... Would have preferred the extra torque too.
some people say the little to no torque loss is negligible and the high end far out ways the loss. but I don't know id hate for the car to feel sluggish.. I have 3.73 gears but I don't know been debating the manifold
if your going centri then the boss manifold should be automatic ,the stock intake stops making power at 6800 rpm so essentially your wasting rpm if you put a centri on a stock IM car. They have torque boosters for the centris you can purchase if you think the car feels sluggish.
