Dodge Charger Hellcat/Demon Mild Catch Can 2015-2023

Stop Supercharger Blowby from Fouling Your 6.2L HEMI Before It Kills Power

The MightyMouse Solutions Mild Catch Can Kit intercepts oil vapors and PCV blowby on the 2015-2023 Dodge Challenger and Charger Hellcat, Hellcat Redeye, Hellcat Widebody, Hellcat Redeye Widebody, and 2018 SRT Demon before they re-enter the intake manifold. Without a catch can, the 6.2L supercharged HEMI constantly routes oily crankcase gases back into the intake, coating the intercooler, throttle body, and intake valves with a buildup that progressively robs boost pressure and throttle response. The MightyMouse Mild kit solves this with an inline billet aluminum canister mounted to the fender or supercharger bracket, capturing contaminants in a see-through sight glass body so you know exactly when to drain it. This is the Mild configuration, designed for stock to bolt-on builds up to 1000 horsepower, with your choice of 8AN or 10AN fittings and AN male flare or OEM quick connect inlet routing.

Key Features

• 6061 Billet Aluminum Body: Machined in the USA from aerospace-grade aluminum with an anodized finish and o-ring sealed end caps that handle sustained boost pressure without weeping or cracking
• Sight Glass Monitoring: Transparent polycarbonate sight glass lets you check accumulation at a glance without removing the canister, so draining is always on your schedule
• Boost Check Valve Included: Prevents boost pressure from pushing back through the PCV circuit during wide-open-throttle pulls, keeping the system sealed and the catch can working correctly under load
• Fender or Supercharger Mount Options: Fender bracket mount is the standard clean install; supercharger mount with cat head bracket routes the can tight to the blower for a more aggressive underhood look
• 8AN or 10AN Line Options: The 10AN 1000hp upgrade uses larger diameter hose to handle higher crankcase volumes in built engines making aggressive power
• OEM Quick Connect Fitment Available: QC inlet option connects directly to the factory PCV hose barb with a push-lock fitting, eliminating the need to cut or modify the OEM line
• All Hardware Included: Push lock hoses, fittings, mounting bracket, and detailed instructions are in the box so installation requires only basic hand tools
• Made in the USA: Every MightyMouse canister is manufactured and assembled domestically to tight tolerances

About MightyMouse Solutions

MightyMouse Solutions is a Virginia-based manufacturer specializing in precision crankcase ventilation systems for high-performance American and import platforms. Their catch cans are machined domestically from 6061 billet aluminum and engineered specifically for the boost pressures and oil vapor volumes produced by factory-supercharged HEMI engines. The Mild and Wild lineups cover stock through full-built applications, and every kit ships with vehicle-specific brackets and complete hardware so installation does not require fabrication.

Frequently Asked Questions

What is the MightyMouse Mild Catch Can for Hellcat/Demon?

The MightyMouse Mild Catch Can is a USA-made billet aluminum inline oil catch can system designed for the 2015-2023 Dodge Challenger and Charger SRT Hellcat, Hellcat Redeye, Hellcat Widebody, and 2018 SRT Demon. It intercepts crankcase blowby vapors before they re-enter the 6.2L supercharged HEMI intake manifold, protecting the intercooler and valves from oil contamination on stock to 1000hp builds.

What is the difference between the Mild and Wild catch can?

The Mild configuration uses a single inline PCV canister handling crankcase output from stock to approximately 1000 horsepower. The Wild system uses dual inlets for high-output built engines exceeding 1000 horsepower that generate significantly higher crankcase volume than the single Mild canister can handle efficiently.

What does 8AN versus 10AN mean and which should I choose?

8AN and 10AN refer to the diameter of the hose connecting the catch can to the PCV system. The 8AN is the correct choice for stock or mild bolt-on Hellcat and Demon builds. The 10AN 1000hp upgrade uses a larger bore hose to support higher crankcase volumes on more aggressively built engines. If you are running a stock or bolt-on tune, the 8AN version is the right fit.

What is the difference between AN Male Flare and OEM Quick Connect fitment?

The AN Male Flare version requires cutting the factory PCV hose and installing AN fittings on the cut ends. The OEM Quick Connect version uses a push-lock fitting that snaps directly onto the factory PCV hose barb without cutting, making for a cleaner reversible installation. If you prefer to keep the factory hose intact, select the OEM Quick Connect variant.

What is the difference between the fender mount and supercharger mount?

The fender mount brackets the catch can in the passenger fender area for a tidy tucked-in appearance. The supercharger mount uses a cat head bracket to mount the can close to the blower, keeping the hose run short and giving an aggressive underhood look. Either mount is functionally equivalent; the choice is cosmetic and based on available space in your specific engine bay configuration.

Will this fit the 2021 or later Dodge Charger?

Yes, but check hood clearance carefully. The 2021+ Charger body refresh changed the engine bay packaging slightly. MightyMouse recommends the fender mount configuration for 2021 and later Charger Hellcat builds to avoid potential clearance issues with certain supercharger bracket positions.

How often does the catch can need to be drained?

MightyMouse recommends checking the sight glass every oil change interval and draining when accumulation reaches the midpoint of the sight glass. Most Hellcat and Demon owners drain every 3,000 to 5,000 miles under normal street driving. Track or frequent wide-open-throttle use increases accumulation rate and may require more frequent draining.

Is the MightyMouse Mild catch can legal for street use?

MightyMouse catch cans are sold for off-road and track use only and are not compliant with emissions regulations in all states. Check your local and state regulations before installing any PCV system modification on a street-registered vehicle. The kit does not affect engine management or require retuning.

Can I use this on a supercharged Demon with the Demon Crate installed?

Yes. MightyMouse Solutions offers a Demon-specific bracket on request for builds using the Demon Crate supercharger assembly. Contact MightyMouse directly when placing an order to confirm the correct bracket configuration for your specific Demon setup.

Installation Instructions

1. Allow engine to cool completely and disconnect the negative battery terminal before starting
2. Locate the factory PCV hose running from the valve cover to the intake manifold on the 6.2L supercharged HEMI
3. For OEM Quick Connect variants: disconnect the factory PCV hose at the manifold barb by pressing the release tab and pulling straight back. For AN Male Flare variants: cut the factory PCV hose at the desired splice point and install the included AN fittings on both cut ends
4. Mount the MightyMouse catch can to the selected bracket location (fender or supercharger) using the included hardware. Tighten mounting bolts to snug but do not over-torque into the fender liner or bracket
5. Connect the inlet hose from the PCV source to the bottom port of the catch can and the outlet hose from the top port toward the intake manifold. Route all hoses away from exhaust manifolds, hot pipes, and moving components
6. Install the boost check valve in line per the MightyMouse instruction diagram, oriented with the arrow pointing toward the intake manifold
7. Secure all hose connections with the included push lock fittings. Verify there are no kinks or sharp bends in the hose routing
8. Reconnect the battery terminal and start the engine. Let it idle for five minutes and inspect all connections for leaks or seeping
9. Check the sight glass after the first drive cycle to confirm the system is capturing blowby and functioning correctly
10. Drain the canister by removing the drain plug at the bottom and disposing of captured oil vapor condensate properly
