Okay got my mp8 installed and everything. Now here is the question. Is there some light that is suppose to indicate that it is on? Or what? I drove it and it seemed to have a little more kick but not for certain.

 

a rail guage will indicate it and a very good thing to have.

 

Yea I guess I should get one of them! Anything else though?

 

I don't think there is a light. It's been a while since I had my MP8 but I bet that if you turn it up on high for a moment you will know if it's working or not. Boxes like that seem to not fuel that great on the bottom end but come on strong once you start building some boost. Give it some pedal and see how it feels....

 

Got it now! Got on the pedal with it turned up and dang it will light em up now! I use to only make around 57 lbs boost out of my setup on twins and now it went up past 65! Unbelievable!

 

Will it hurt to run my smarty on RP 2 setting when I have my mp8 on?

 

You really ought to monitor RP while running a pressure box - especially stacked on top of SW... sux to eat up rail releases or blow the solenoids off.

 

We have done extensive testing with the Smarty stacked with pressure boxes, and have always made more power with the Smarty on RP-1. Let the pressure box do its job.
