Gain a huge performance advantage with the ultimate secret weapon. BoonDocker™ Liquid Nitrous Kits provide an extra blast of horsepower at the push of a button. Each kit comes set up for approximately a 30 horsepower gain but can be adjusted for as little as a 10 horsepower gain to as much as a 75 depending on the model and options.
These kits are compatible with 91 octane fuel for most combinations up to a 20 horsepower gain. Higher octane levels are required for higher horsepower combinations. An SLP technical representative will gladly help you decide what fuel quality would be required for the combination you are planning to use.
BoonDocker™ exclusive include: a 3 lb. aluminum bottle that weighs the same as most 2.5 lb aluminum bottles but holds a half a pound more nitrous, a bottle valve that is 1" shorter and 5 oz. lighter than industry standard bottle valve, push to connect fittings for ease of installation, Synergy Series Operation (which allows the use of a nitrous pressure regulator to provide maximum nitrous consistency, and button-less activation for fully automatic nitrous control for EFI models).
Sold in kit form, please choose the kit and bottle size you prefer (AL=Aluminum, CF=Carbon Fiber). Aluminum bottles can be polished to high gloss finish for a custom look, Carbon Fiber bottles weigh less than aluminum bottles and provide better insulation characteristics which keeps nitrous temperatures (and pressure) more constant. Purchase additional bottles or 20 lb refill station at the time you order (ask your salesperson for details).
The key to making nitrous function properly on carbureted snowmobiles lies in BoonDocker's™ patented nitrous manifold, which varies fuel delivery as nitrous pressure changes (due to temperature fluctuations) making these kits simple and easy to use (initial setup requires experienced tuning). For even more consistency a Synergy Series pressure regulator can be added to the kit to provide exactly the same horsepower each and every time the button is pushed. The adjustable regulator effectively allows you to adjust horsepower up or down (from 20 to 50 horse) easily to match fuel quality and snow conditions. The nitrous manifold automatically compensates fuel delivery for changes in nitrous pressure when the regulator is adjusted.
EFI models require the use of a BoonDocker™ Synergy Series Nitrous Control Box. (See "Related Items" tab above) This control box has become the industry standard for fuel and nitrous control. With this Synergy Series Control Box, BoonDocker™ has taken EFI nitrous control to the next level, monitoring throttle position and RPM to provide the next evolution in nitrous control.... Button-less activation for fully automatic nitrous control. If the bottle and nitrous control are turned on, the rider doesn’t have to think about pushing a button but instead, the nitrous control box monitors engine load and activates the nitrous when needed. This feature maximizes nitrous mileage, while allowing the user to concentrate more on riding the snowmobile rather than pushing a button. For users who prefer a button activation, this is also an option. The button can even be programmed to control other options such as adding fuel only, or capturing and holding your nitrous box screen data so that you can come to a stop and safely read the screen information. For even more consistency a Synergy Series pressure regulator can be added to the kit to provide exactly the same horsepower each and every time the nitrous is activated. These regulators are offered as either a fixed regulator or an adjustable regulator. With the simple twist of a dial, the adjustable regulator allows you to adjust horsepower up or down (from 10 to 75 horse) easily to match fuel quality and snow conditions. It is no longer necessary to manually change nozzles every time you want to change your nitrous horsepower. The nitrous control box automatically compensates fuel delivery for changes in nitrous pressure when the regulator is adjusted.
