The Mightymouse GREEN Solution:

Environmentally friendly high performance crankcase flow and emissions control.

 

     The times of lacking PCV emissions function for the sake of on track and competitor safety or class rules is over.

     Now you can meet those needs while not only having crankcase emissions control, but in many cases improving it.

     Our PCV systems, when installed properly and running to spec. can reduce hydrocarbons and nitrogen oxides, compared to without.

     Even our most aggressive motorsport / off road systems are a green alternative to traditional catch cans.  When not in overload protection mode they still operate in a closed loop PCV system.  This is a significant and unique change to motorsport, which has been dominated for the last 50 years by full PCV removal, using devices with zero emissions mitigation.

     The power handling and surge control of a race only ventilation system, without sacrificing emissions, is here.  All of our catch can systems are fumes controlling and crankcase filtering PCV systems.  We have multiple trim levels and top options to suit your needs, from mild to wild.

     It is the Mightymouse green solution that the automotive aftermarket needs for our environment.

 

  • Reduce oil loss caused by internal consumption and external leaks

  • Lower maintenance costs of carbon build up and deposit removal

  • Raise performance metrics, from HP to MPG

  • Lower emissions for everything from stock road cars to motorsport

MM Gen 5+ Technology:

Developed over 5 build generations of catch cans, we do our own testing to prove out our parts, on the bench and the track.

As our standards increased so did our validation requirements.  Eventually this led us where we had to invent our own test equipment, assemblies, and methods to be fair to ourselves and our customers, and bring Real Data to a business previously dominated by hype.

Our vapor efficiency test is Hard.  It is a several hour long test where we atomize oil and draw this through the test can.  The amount of oil dispensed is compared to the amount caught during constant conditions so that the results below are very relevant and repeatable.

 

Our flow test is Hard.    We hook up to a very large supply line, and quite simply blast the can with air, but with a very particular strategy, from 0-3psi of pressure, while monitoring 7 different digital sensors.  This data is recorded at 50 times per second and compiled.

Quite frankly these tests put most every catch can on the market to Shame.  The storage rack is literally called the 'Wall of Shame'.  Examples of our testing shared Here.

 

MM Gen 5+ Performance:

MM Gen 5+ Applications:

The RACE can is an unregulated extreme flow filter, catching whatever liquids come from the crankcase.

It is completely passive, no moving parts.  1-3 unrestricted and high flow crankcase connections.  This can be used in diesel applications or on the surge side of most pcv systems.  This unit also has motorsport applications when emissions do not apply.

 

The PCV can hooks up two ways, both closed for vacuum scavenging and open in times of pressure. 

1. This is spliced directly in-line of the stock PCV system to catch oil normally consumed by the PCV and gives some crankcase pressure relief.  Because it relies on OEM PCV line sizes; Increased HP capacity is limited.  This is the can assembly you will find within most of our 'MILD' Complete kits.

2. This is a new stand alone PCV system run by the can.  The stock PCV valve is usually retired.  A new, larger, and unregulated connection to the crankcase is made to the can.  The can is self regulating and now in charge of running the PCV system, and has optional 100PSI built in boost checking connection to the intake manifold. This configuration is the max effort bells and whistles fix for people who want a PCV system and high HP.

Clean air still comes into the crankcase to filter out particles/fumes/moisture during regular driving and is constantly scavenged back out by intake manifold vac (just like stock).

Because of the special configuration; we are no longer 'restricted' by the factory system, and can connect to the crankcase with full-flow or multiple fittings to accommodate high hp.  This is the can assembly you will find in our 'WILD' complete kits.

 

It is expected these installations to be handled by someone Mechanically inclined.

Installing catch cans incorrectly can result in engine damage.  It is up to you to ensure installation and connections are done to spec before running your engine, and that any question or concern be relayed and evaluated before further use.

 

Owner Responsibility:

The catch cans hold 4oz until liquid shows on the oil sight (drain now). 6oz is maximum capacity (half way on the sight), and at 8oz the can is completely full (sight is full) and will be bypass the collected oil.  Some fill fast, some slow, but it is extremely important to not let the can overfill and it is up to the owner to be in charge of this. Extended use near or below freezing, including storage can lead to increased condensation and water in the can.  Not only does this take up volume as mentioned above, but water can also freeze and stop the airflow through the can possibly causing engine damage.  Please feel free to contact me with any questions or concerns.

Racing Warning:

This can is NOT a solution for a bad engine.  Use on one with excessive blowy from damage or poor construction, over the course of a racing event, is at the owners risk.  There is no way to assume this can is able to hold much engine oil.  In some instances it can and will overflow to anything near the discharge, damage such as fire or injury can result.  It is up to you to monitor on your own.

 

PICK THE RIGHT THING: 

The catch cans and systems only work as well as you did making sure what you bought is what you need.  After determining which can type you need, you may also want to make sure that the hoses and fittings mounted to it and your engine are right for your application.  Above is a quick spreadsheet (tab) to help you see why the right size hoses make all the difference!
