Compucar's Blaster Nozzle is a new development in dual inlet nozzles. Separate channels pass thru the blaster nozzle body, one for nitrous oxide, and the other for fuel enrichment. When the system is activated, the fuel and nitrous oxide mix as they exit the blaster nozzle body's tip. Mixture atomization with the Blaster nozzle body have increased the power potential significantly.

1. Position the Blaster nozzles in each intake runner as close to the intake valve as possible. Consider carefully the position of carburetor linkage, fuel lines and valve cover access.
2. Scribe the manifold to mark the location for each blaster nozzle. Try to keep the blaster nozzles as straight as possible across the intake and in the center of each runner.
3. If the intake is still on the engine, it must be removed for all drilling and tapping. It may be installed for all remaining procedures.
4. Drill a 11/32 inch hole at each scribe location and tap 1/8 npt thread. (Special note- the angle at which the drilling and tapping is performed will greatly effect the clearances and appearance of your system.
5. Insert a Blaster nozzle into each tapped hole, using a little thread sealer (Liquid Type Not Teflon Tape), and tighten so that the Blaster's output is pointing in the intake flow direction, which is toward the intake valve.
Forming the runner injector lines
1. Locate distribution block between the center intake runners on each side of the intake being certain adequate clearance for lines to lead to and attach to the block.
2. Distribution lines are constructed from 3/16" steel brake line, but 3/16" stainless tubing can be used for a more custom touch.
3. Distribution lines may be bent by hand or around a 7/16" diameter bolt or by using a tubing bender.
4. The tubing supplied in the kit has one end already flared. Slide a blue tubing sleeve and tubing nut on to the line. Bend tube as necessary to go from blaster nozzle to distribution block.
5. Both fuel and nitrous solenoids attach as illustrated. (screw tee fitting into solenoid end marked "out").
System main supply lines
1. Using the holes in the bracket bases as a template, mark and drill holes to secure the mounting brackets to the mounting surface. We recommend 3/8" bolts, washers and nuts for a secure installation. The bottle valve end must be higher and the bottle output adapter pointing straight DOWN. Tighten the mounting bracket wing nuts. (See Diagram over).
2. Install the long braided, stainless steel main supply line. It must be routed under the vehicle. Locate and drill a 5/8" diameter hole near the bottle valve in the sub flooring. Route the line through the hole in the sub flooring and along the frame away from the exhaust or any moving suspension parts that may damage the line. Securely fasten the AN nut on the line to the bottle adapter. You may also want some silicone or a split grommet to keep the line from possible harm when running through the sub floor.
3. Install nitrous filter on the main supply line under the hood, keeping in mind the flow direction noted on the filter. Now take the 1 foot line supplied in the kit and put on the outlet side of the filter. The other end of this line will go to the inlet side of your nitrous solenoid.
WHEN BLOWING OUT THE MAIN NITROUS LINE, ANCHOR THE LOOSE END SO IT WILL NOT WHIP AROUND AND STAND CLEAR!!
THE EXTREMELY COLD HIGH PRESSURE BLAST EMITTED FROM THE OPEN END OF THE LINE COULD CAUSE HARM OR EXTREME FROSTBITE!!
4. Before installing the main nitrous supply line to the nitrous solenoid, make sure the bottle valve is "cracked" open for 4 seconds. This blows out any foreign matter in the nitrous line. Immediately tighten main feed line to the nitrous solenoid's inlet fitting.
DUE TO THE EXTREMELY HIGH HORSEPOWER THE BLASTER SYSTEM IS CAPABLE OF PRODUCING, IT DEMANDS A CONSTANT AND UNRESTRICTED SUPPLY OF FUEL TO INSURE OPTIMUM SAFETY AND PERFORMANCE. IN MOST APPLICATIONS IT WILL REQUIRE THE ADDITION OF A SEPARATE HIGH FLOW SYSTEM JUST FOR THE NITROUS SYSTEM. IT SHOULD CONSIST OF A HIGH VOLUME ELECTRIC FUEL PUMP, ALONG WITH A MINIMUM 1/2" FUEL LINE AND A SEPARATE FUEL REGULATOR.
1. Disconnect the battery ground cable. Your 12 v source should be taken from the fuse panel marked accessory. This will ensure the nitrous oxide system will be activated ONLY with the switch turned on. Be sure all connections are well insulated to avoid possible shorting.
2. Select a location within easy reach of the driver and mount the "ARM" toggle switch and "ACTIVE" push button switch. The push button switch is a momentary switch and must be held down to operate the system.
3. Connect a piece of electrical hookup wire from the 12v source to either terminal on the toggle switch. Connect a piece of hookup wire from the remaining terminal on the switch and connect it to a terminal on the push button switch.
4. Connect one wire from the nitrous solenoid valve and one wire from the gas solenoid valve to the other terminal on the push button switch. Connect the remaining wire from each solenoid valve to a good ground.
Final system check up
With all the electrical wiring completed, reconnect the battery. Open the nitrous bottle fully and check ALL nitrous connections for leaks and tighten as necessary. Start the engine and check ALL Fuel side connections for leaks.
Now start your engine and allow the motor to warm up to normal operating temperature. If the engine idles and runs smoothly, open the nitrous bottle valve fully and head for the nearest test area.
WITH THE CAR IN DRIVE UNDER WIDE OPEN THROTTLE ONLY, PRESS THE ACTIVATION BUTTON AND ENJOY!!
**SPECIAL NOTE** Compucar Solenoids have a bubble tight seal, however as an added precaution, close the bottle valve when the engine is not running.
1. High flow regulator (Part # 342210) allows for fuel pressure adjustments.
2. Fuel Pressure Gauge (Part # 342230)
3. Fuel Pressure Safety Switch (Part # 342515) monitors fuel pump pressure and shuts nitrous system off it fuel pressure drops below safe level.
4. Competition Vapor Purge Kit (Part # 258000) allows the main line to contain only liquid nitrous when the system is activated, causing the initial horsepower of the Blaster system to be greater, and allowing the unit to "hit" harder.
