HEMI INTAKE SHOOTOUT+BONUS TEST!

FULL HEMI RESULTS. WHO WINS-TRUCK vs MAGNUM vs SRT8? We compared the Truck, Magnum and SRT8 intakes to a Mopar Performance single-plane on a small, Gen-3 Hemi stroker. Which one makes the most power? Most peak torque? Most Average Torque? Bonus Test-Edelbrock Dual-Quad vs MP Single Plane. Dual Quad Hemi FTW!

[@ravennexusmh]

Area under the curve everywhere on that magnum intake is definitely worth the minor top end loss vs the single plane

[@fascistpedant758]

Those were pretty small cams for a single plane.

[@Dr_Xyzt]

@@fascistpedant758 Yeah. But the total package on that magnum intake is very effective. If you shift at 5500-6200, you get a very nice long-lived package that runs GREAT without the hassles of higher RPM use.

I have a charger timing cover available, so I can get around the typical truck intake obstructions. My stock '07 ram intake has a pretty serious port mismatch with the eagle heads. According to Inertia Motorsports, I should just make some paper gaskets and run my intake. After spending what I have at this point to stroke and cam my engine, using an intake with port mismatch seems seriously counter productive. Can you make a suggestion on what intake to use? I know people have used the MSD rpm window switch to run an active runner intake, but I have been told the actuator is controlled via PWM from the ECM, so straight voltage input from the window switch shouldn't work correctly. Seriously confused about which direction to go and hoping you have some input. I am only concerned about making the most torque possible as this is in a truck. High rev hp numbers are unimportant.
