Howdy folks,

I'm putting an Eaton M-90 on my truck. I've been advised to remove the IMRCs from the lower intake manifold. However, never one to jump to action from the word of a single individual, I thought I'd canvass the collective genious that is f150online.com for opinions/thoughts. I've read that the IMRCs stay closed to help develop "massive" torque at low RPMs and then open at higher RPMs to let the engine open up and breathe. Now, if I remove them, and run 7 lbs of pressure from the S/C, will I hurt torque development? I'm looking for any/all educated information on the results of supercharging my engine and removing the IMRCs. Any help is truly appreciated

 

i would think removing them on a supercharged engine would help torque becuase it is pressurised. the reason for short and long runners is for NA motors to keep velocity up. with a supercharger you shouldnt have that problem.

i would go to the supercharger turbocharger part of the boards they might have more info on this.

 

remove them for a boosted application. It will help with overall flow.
