Honestly, the MP8 or any pressure box should never be used unless you wanting to mess around i.e. race or go to the strip, etc.....
Anytime you can get more airflow to each cylinder it's worth the money. These motors are not pricey so yeah, it's better to be safe than sorry.thanks for the advice on the tst. what about some 90 hp injectors and an arson 3, would this be a good next step? what about an intake/ exhaust manifold? are they worth the money?
