THE BLACK TEE HANDLE REGULATOR IS PRESET AT 40 PSI
AND REQUIRES NO ADJUSTMENTS
It is normal for the lockoff / valve solenoid to become very hot when in operation.
Starting pressure adjustments - The stock system setting is normally set at a 5 lbs start time unless a custom calibration was requested when ordering.(for example-a performance setting comes in at 2-3 lbs boost while a towing only setting comes in at around10 lbs boost.
To change when the system activates (the boost pressure the system comes on at):
To set for Performance Gains – (set level to lowest start time setting):
Remove both hoses from the regulator. Turn the system on; loosen the 1" jam nut located on the top of the Powershot. Apply a minimum of 2 psi with air pressure, which will simulate boost pressure to the bottom of the Powershot. Screw this assembly out until you hear gas escaping. Then, turn the assembly in until the gas stops flowing. This is the lowest setting of the regulator (approximately 2 psi start time) Tighten the 1” jam nut to lock this setting. This adjustment is very sensitive. It is recommended to mark the factory setting for future reference.
To set for Propane and Fuel Economy (Towing):
Follow the procedure above, EXCEPT: Screw in (right) for a later start time, (up to 15psi boost) or screw out (left) for an earlier start time (down to 2psi boost).
For the best fuel economy while towing - set regulator start pressure 2-3 psi lower than average boost pressure when running on flat grade.
To reset to stock setting or any other start pressure setting, you can use a low pressure adjustable regulator or a Mighty Vac ® pump that reads pressure to simulate boost pressure and apply it to the bottom of the Powershot follow the steps above, (turn system on, remove hoses) and adjust to the starting boost pressure you desire. The slightest flow indicates start time. Tighten the 1” jam nut to lock setting in.
Flow Limit Adjustments: The Powershot 2000 does not contain fixed orifices but has an easy adjustment screw for regulating the flow for your specific needs. (i.e. towing, propane economy, performance, etc.) To adjust the flow of LP fuel-loosen 7/16” nut (located next to the Powershot 2000 engraving) turn this screw in for less LP flow. This is recommended to increase propane and fuel economy, Turn this screw out for more LP flow. The maximum adjustment is six turns out Make these adjustments in ¼ turn increments. The maximumflow rate is not recommended for vehicles with extreme performance enhancements such as computer modules/chips or fueling boxes (over 100 hp). Please use caution when making these adjustments. Listen for any signs of engine knocking or rattling when increasing the flow. Turn system off immediately and readjust to the stock setting if any engine knocking or rattling occurs. This can indicate engine detonation, caused by excessive LP flow.
****IMPORTANT-These adjustments should only be made in well-ventilated areas only. Propane is extremely flammable.****
REMOTE MOUNTING OF THE POWERSHOT UNIT WILL REQUIRE THE USE OF HIGH PRESSURE PROPANE HOSE BETWEEN THE TANK AND THE POWERSHOT REGULATOR. THE LOCKOFF VALVE AND BLACK TEE HANDLE REGULATOR MUST REMAIN AT THE TANK
