Banks Power 45004 Straight-Shot Water-Methanol Injection System
Fits Most Diesel Motorhomes - High Volume Pump
The Banks Power 45004 Straight-Shot Water-Methanol Injection System for your diesel motorhome is designed to increase power and performance by cooling your temperatures. This motorhome specific kit includes a harness extension to properly install in a Pusher Motorhome application.
The Banks control interface for both injection systems is simple yet sophisticated. Completely housed in a compact, easily-mounted 2-1/16” gauge head unit, it allows the user to fully command 2 stages of injection for maximum tunability. It also doubles as a multi-function gauge, displaying boost or TPS %, EGT* and pump duty cycle on the digital display, as well as indicating system activity and any errors with the on-board LED (*optional, available when equipped). Universal models contain a high-precision on-board 100 PSIA pressure sensor for boost sensing, while plug-and-play models connect to your factory MAP sensor.
The system can be configured to inject based on boost pressure or a throttle position signal, exhaust gas temperature, or a combination of both. Fully adjustable progressive multiple-stage control allows for fine-tuning when towing or racing; whether you're after mileage improvements, EGT reductions or big power gains. This versatility allows for use on gas, diesel, boosted or normally aspirated applications; It can even be used for external cooling on intercoolers or brake systems!
The injection nozzles are nickel-plated brass, specifically designed for this application to achieve optimal atomization of water or water-methanol over a wide pressure range. A large 5/8” wrenching hex makes installation a breeze, and a stainless steel screen is integral to keep debris out of the orifice. A range of sizes is provided with each system, with 10 flow rates available to custom-tailor system performance.
Advanced Heavy Duty Pump
Two different pump output volume ratings are available to properly match your engine's needs and offer proper adjustability. Both pumps feature a built-in output pressure switch for low fluid or leak detection, an adjustable re-circulating pressure regulator, integral push-lock fittings and a rubber-isolated mounting bracket for a clean, quiet installation.
Fittings and Plumbing
The best plumbing available is provided with the highest cross-sectional flow area of any system on the market. Nylon tubing and EPDM seals are methanol compatible and can withstand 300 PSI at underhood temperatures. Installed fittings have 360° swivel capability for full flexibility.
Solenoids and Check valves
Dual-stage systems include both a low-restriction check valve for the primary stage, as well as a huge, all-stainless 3/16” orifice control solenoid for the second stage - properly sized components minimize pressure drop prior to the nozzle, maximizing output and atomization. The controller will support a second solenoid in place of the check valve for maximum system performance. (Note: Solenoids are optional on Straight-Shot systems)
No cutting, splicing, and crimping here! The wiring harness is fully connectorized with automotive grade sealed connectors. Designed to plug and play with most factory boosted applications with enough length for virtually any installation configuration. Plug-in extensions and adapters are also available to aid in custom applications.
The system is smart enough to detect when wiring, connection or component faults have occurred and will alert you to the problem. The System Safety output allows further action to be taken when the controller detects a fault or low fluid condition.
Exhaust Gas Temperature (EGT)
A plug and play EGT sensor may be added to the Straight-Shot system to serve as a trigger or auxiliary sensor. When in use, the display can also show EGT. Great option for diesel owners! (Sold Separately)
Multiple Tanks Sizes Available
Select from 3/4, 2-1/2, 5 or 7 gallon tanks that can be mounted anywhere on your vehicle depending on your specific needs. Or simply plumb the system to run from your existing washer fluid reservoir with the included fitting. (Tanks sold separately)
