Well most people already know what Supercharger we are planning to run. With our intake addapter plates we are now able to physically bolt up a 2003-2004 Cobra EATON M112 Superharger to the 4.7L engine.

This Supercharger can handle just over 10PSI while many Cobra guys are getting over 13PSI out of them without any issues.

The great thing about being able to bolt up the EATON M112 is that Whipple makes a 3.4L that will bolt right up in place of it!

SUPERCHARGER ROOTS STYLE - The 4.6L Cobra has a lower intake manifold which houses a FLOW THROUGH heat exchanger. Running ice water through this should drop the blower charge temps which will allow us to run more boost safely.

Yes but you already know that its 10PSI on a 4.7L engine.

The heads flow just over 278cfm @050.

A small effort of research would have all this information right in front of you.

I dont think your a jerk... You just have not been following our build up. .... Now you know.

2002 Dodge Ram 4.7L with Sullivan Single Plane intake manifold. To date there is NO loss of low end torque but a HUGE gain of top end pulling power. With the Sullivan Intake and only a base SCT tune with 26 degrees of timing advance and an AFR of 12:1 across the RPM range our 5125lb Quad Cab Ram ran:

R/T....... .147
60'........ 2.285
330....... 6.366
1/8....... 9.733 @ 72.28
1000..... 12.712
1/4....... 15.229 @ 89.76

There is room for tuning improvement. I would like to think we can make another 15-20RWHP with some tweaks.
