All these modifications are smoothed and polished to provide the highest velocity airflow with as little turbulence and drag by surface deviation of the intake manifold as possible.Īll these modifications were designed and tested by our top HEMI engine builders and are performed by the HEMI engine builders using a combination of CNC milling and hand work for the best possible air flow in your Custom Ported Stage 1 and Stage 2 HEMI Intake Manifolds. 09-22 Chrysler, Dodge & Jeep 5.7L Hemi, 6.1L SRT8 & 6.4L 392 Sniper Intake Manifold by Holley 837251 / 837252. As a finishing touch the fuel injector bosses are reworked and smoothed for optimal air flow. Those Ports are port matched with Arrington ported heads. The intake runners and Intake Runner entries are opened and angled to provide optimal flow into the head port. ARP Chrysler Small Block 5.7/6.1L Hemi 12pt Intake Manifold Bolt Kit - 444-2103. The plenum is blended from the opening into the runners for a smoother transition and increased airflow and velocity. Our first style includes a dual mounting pattern 90mm Mopar drive-by-wire for use with stock 5.7L/6.1L or 6.2L Hellcat throttle bodies.
6.1 hemi intake manifold plus#
Personally if your car is stock I would leave the 5.7 manifold on it, your car's cam will not let it perform up at 6200 rpm anyway so power gains are minimal, plus the additional heat soak from the metal vs plastic intake negate some. rails on the 6.1 look nice if you want to use them. The throat of the custom ported intake manifold is opened to match our 90 mm HEMI throttle body. 6.1 injectors will swamp a stock 5.7 unless scaled back. Holley Sniper EFI Race Series Fabricated Manifolds continues to push the aftermarket by introducing applications for Mopar Gen III Hemi Engines.
6.1 hemi intake manifold upgrade#
For the stage 2 intake manifold upgrade we spend twice the machining and milling time to achieve the highest airflow possible from a ported and polished intake manifold. Get maximum airflow from your intake manifold upgrade in your 6.1 HEMI SRT-8 Dodge Charger, SRT-8 Chrysler 300c, or SRT-8 Dodge Magnum. item 6 Edelbrock 8528 Intake Manifold Bolt Kit, Dodge, Hemi, 5.7L, 6.1L, 3/8 in.-16 x 6 -Edelbrock 8528 Intake Manifold Bolt Kit, Dodge, Hemi, 5.7L, 6.1L, 3/8 in.-16 x.
