The Sonoramic Commando Intake?

So, they were merely for low end torque and low RPM's, that, I did not know.....

I knew that the Cross-Ram used on the Hemi back then was for high RPM's, why was the Sonoramic Commando Intake low RPM tho? Or well rated as such, did it restrict fuel/air flow or what?

different exhaust manifolds, why?

These damned things look cool as hell but are a complicated SOB just to understand, I can see why the guys trying to "tune" in the whole set up complain!



To put it simply, the cross ram was just a high rpm version of the sono rams.

Long runners are for lower rpm, and shorter runners are for higher rpm. When you shorten them enough to get high rpm efficiency, you end up with cross ram....


They tune the intake pulses and exhaust pulses to peak at certain power bands.
