    DSE-VP-CC-002-xxx Gen V Viper Catch Can Kits

    DSE offers complete catch can kits for the Gen V Viper. Kits include everything needed for installation. Hoses are cut to length by the installer for maximum flexibility on installation location. Links to order and installation instructions can be found on the website http://dougshelbyengineering.com/Viper.html

    Catch Can Overview
    Blow-by gasses vented from the PCV system contain oil and fuel that can be ingested back into the intake manifold and airbox. This “sludge” can contaminate and reduce flow through the air filter, reduce the effective octane rating of fuel, increase chance of knock / detonation, reduce power, and fuel economy. Catch cans condense and filter oil and fuel from blow-by gasses and reduce or eliminate the amount of contaminants entering the engine.

    Catch can setup depends on personal preference and expected vehicle usage. Typically a sealed catch can setup is used for a vehicle driven on the street, while a vented setup is preferred for the track. Both setups are equally effective at cleaning blow by gasses. A sealed system keeps the emissions system intact and inserts the can inline to collect oil/fuel. A vented system removes the PCV valve and system and vents the filtered air into the atmosphere instead of back into the engine. Typically used for track only cars and can produce fumes that could be undesired for the street. Relief of excess pressure and drag from the engine components and may provide a performance advantage under high RPM/load. Since the oil is exposed to the atmosphere, more frequent oil changes are recommended as is typical with track only vehicles

    DSE Catch Can Kit Features
    - Non invasive: No drilling.
    - Bracket clamps around the front or side crossbars, the
    design reduces potential marking or damage of the bar.
    - Easy and quick installation, three screws install the bracket.
    - Universal fit allows Catch can to be mounted in multiple DSE dual input vented and single input sealed catch cans locations around the engine bay.
    - Lightweight, pocketed design; billet aluminum.
    - Durable hard anodized finish.

    Great product! I opened mine up after about 200 miles last weekend and had about an 1/16 inch of oil all across the bottom of my can so it's definitely working.

    I thought I would share this photo of a great looking ACR engine bay. What I wanted to point out is the routing of the hose into the intake manifold. This is the way Woodhouse has been installing the kits and I think it is a good option for people to consider when doing their own installs.

    Maintenance:
    - Check your catch can often during the first 1000 miles or after every track day to understand how often it will need to be drained.
    - At 1000 miles remove, inspect, and clean the brass filter.
    - Ongoing maintenance will be determined by your findings during the first 1000 miles, vehicle modifications, and usage.
    - After each engine modification or change in how the vehicle is used (track, strip, etc.) keep a close eye on the catch can to understand the amount of oil collected.

    I've added an application note to my website which should better describe the differences between the kits from a performance perspective.

    http://dougshelbyengineering.com/upl...ation_Note.pdf

    Single sealed catch can kit P/N: DSE-VP-CC-002-SSK
    Pros:
    o Passenger side installation will condition gasses that enter the intake manifold
    o Keeps the emissions system intact, including the PCV valve
    o Cost effective
    Cons:
    o Only working when the PCV valve is open
    o Does not address WOT condition where PCV valve can close (see below)
    o PCV valve may close at Full Throttle / High RPM / High Load (when highest volume of blow by gas is generated):
     untreated blow by gasses are forced back into the airbox
     crank case pressure may build if airbox line is too restrictive, robbing performance
     Any modification that adds torque or HP will increase the odds of this scenario
    Recommended for:
    o Mild street driving for stock or mildly modified engines

    Dual sealed catch can kit P/N: DSE-VP-CC-002-DSK
    Pros:
    o Passenger side installation will condition gasses that enter the intake manifold
    o Driver side installation will condition gasses that enter the airbox
    o Keeps the emissions system intact, including the PCV valve
    Cons:
    o More expensive than the single kit
    o Address the results of the WOT condition where PCV valve closes, but not the cause (see below)
    o PCV valve may close at Full Throttle / High RPM / High Load (when highest volume of blow by gas is generated):
     blow by gasses are forced back into the airbox through driver side can
     crank case pressure may build if airbox line is too restrictive, robbing performance
    Recommended for:
    o All stock Vipers driven with a decent amount of spirited street or track driving
    o All Vipers that have been more than mildly modified

    Dual sealed catch can kit (PCV Delete) P/N: DSE-VP-CC-002-DSPCV (coming soon)
    Pros:
    o Passenger side installation will condition gasses that enter the intake manifold
    o Driver side installation will condition gasses that enter the airbox
    o Address the cause of the WOT condition where PCV valve closes by removing PCV and changing airflow
     Crankcase pressure buildup at high RPM/throttle/load is reduced or eliminated
    • Larger lines to airbox
    • Both cans are actively cleaning each side of the engine via airbox vacuum
     Benefits of the vented system without being open to atmosphere
    Cons:
    o More expensive than the single kits
    o PCV valve is removed, intake manifold is capped, airbox line is changed, therefore emissions system is modified
    o IAT might be slightly higher as compared to the other systems
    Recommended for:
    o All stock Vipers driven with a decent amount of spirited street or track driving
    o All Vipers that have been more than mildly modified
    o Track cars not wanting to use a vented system

    Single can vented catch can kit (OFFROAD ONLY) P/N: DSE-VP-CC-002-SVK
    Pros:
    o No crankcase air is entering the intake manifold or airbox
    o Cost effective way to reduce crankcase pressure build
    o IAT will be lower than and of the sealed kits
    Cons:
    o Single can
     will not have the ability to flow or clean as much as a dual sealed PCV delete or vented setup
     lower capacity, more frequent emptying
     installation is not as clean as a dual vented setup as hoses cross the engine bay
    o PCV valve is removed, intake manifold and airbox are capped, therefore emissions system is modified
    o Open to atmosphere, recommend increased oil changes after every event
    o Possible fumes / residue / smoke from filters
    Recommended for:
    o Offroad use only, track vehicles with regularly changed fluids

    Dual vented catch can kit (2 cans, OFFROAD ONLY) P/N: DSE-VP-CC-002-DVK
    Pros:
    o Better flow and pressure reduction than the single vented kit
    o Higher capacity than the single vented kit
    o Cleaner installation than the single vented kit
    o No crankcase air is entering the intake manifold or airbox
    o IAT will be lower than any of the sealed kits
    Cons:
    o More expensive than the single vented kit
    o PCV valve is removed, intake manifold and airbox are capped, therefore emissions system is modified
    o Open to atmosphere, recommend increased oil changes after every event
    o Possible fumes / residue / smoke from filters
    Recommended for:
    o Offroad use only, track vehicles with regularly changed fluids
