Installatin - Mechanical Step 1 Reservir Install Install 90 degree elbw int reducer bushing using E6000 sealant. Turn ½ turn past finger tight. D nt use Tefln sealants n Snw Perfrmance fittings. Install reducer bushing int reservir utlet using E6000 sealant. Turn ½ turn past finger tight. Maintenance Remve nzzle(s) and clean screen filters at least nce per year using carb cleaner. The Bst Cler has been designed t perate with high cncentratins f methanl. Oil r ther additives are nt required fr system lubricatin. Fr best perfrmance, cling and system life it is recmmend that Snw Perfrmance Bst Juice (#40008) be the exclusive fluid used in the system. Test fit reservir in desired munting lcatin. Typical placement is tucked up alng the side f a pickup bed r in a bed munted tl bx. Check the area under the bed near the desired munting lcatin. Nte the lcatin f fuel tanks, fuel lines, and wiring. Mark the lcatin f the fur aluminum munting strap tab blt hles. Drill thrugh bed with apprpriately sized drill bit. USE CAUTION WHILE DRILLING. Munt reservir with aluminum munting straps using apprpriate hardware.

Tuning Quick Reference If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity. This can be dne by: 1. Using a smaller nzzle(s). 2. Using Screen 10 and Screen 11 t adjust the gain. Cautin****** Prlnged quench may cause lwer engine damage ver a perid f time. Als, fresh methanl less than 1 mnth ld when expsed t atmsphere and using a greater methanl cncentratin up t 50% - will reduce cmbustin quench. 100% water will cl cmbustin and EGTs and will increase pwer apprx 20-30 HP. 75/25 water/methanl will reduce EGTs and pwer will increase apprximately 40 HP. 50/50 water/methanl will reduce EGTs and increase pwer apprximately 70+ HP. Cautin****** T avid gravity feeding f fluid with rear munt reservirs, it is essential t use a slenid in-line between the reservir and pump. D nt perate yur rear munt equipped vehicle withut a slenid installed. Step 2 Pump Install Munt the pump s the inlet is psitined at the lwest pint f the reservir r lwer. Pump can be munted hrizntally r vertically using the supplied screws and washers. Ensure that n sharp bends in the high pressure tube ccur near the pump. Sharp bends can cause stress n the inlet and utlet prts f the pump, causing leaks. Trim tube with a utility knife r razr blade, making sure t eliminate any burrs r kinks n the end. Insert firmly int the pump abut ½ inch thrugh the light grey lcking cllar. Nte the arrws indicating flw directin n the tp f the pump. T remve the hse, gently and evenly push the light grey lcking cllar int the head unit f the pump, then pull n the hse gently. Cautin: T avid pling in the intake it is recmmended that: 1. The engine be run withut water/methanl fr at least 5 minutes after injectin befre turning the engine ff. 2. The armed switch is turned t the ff psitin when the engine is ff. Cautin: D nt attempt t inject water/methanl until the engine has reach perating temperature. A cld engine is mre susceptible t quench and pr perfrmance. Measure the distance frm the reservir utlet t the pump inlet. Cut the ¼ red tubing using utility knife. Make cuts are as square as pssible.

Ensure there are n kinks in the tubing and insert tubing int quick discnnects at pump and reservir until fully seated. Keep the pump within 2 feet f the reservir. The pump can be munted under the truck bed in a place prtected frm rad spray. Cautin****** Pump must be shielded frm rad debris and tire wash. Failure t d s will result in pump failure Step 3 Nzzle Selectin Activatin f pump fr shrt perids (1-5 sec.) will purge air bubbles frm the system. This can be accmplished during initial use. Step 2 Test Cntrller With the nzzles remved frm the intake, place the cntrller in bst nly mde by disabling the EGT Cntrl mde. Set gain t 100. Using a hand pump, apply 10-20 psig f pressure t the bst line leading t the cntrller. Pump shuld activate, fluid shuld flw, and tank level shuld g dwn. Nzzle sizing is a functin f hrsepwer, which apprximates the engine airflw, and bst, which apprximates intake charge heat. Often nly ne nzzle is needed. Recmmended starting pints: 250-350 WHP 625 ml/min nzzle 400-500 WHP 375 & 625 ml/min nzzle 550-650 WHP 2 X 625 ml/min nzzle Seal the nzzle int the nzzle hlder using included GOOP sealant. Using a sealant that is nt permanent will allw fr nzzle changes during tuning. Simply remve the nzzle, clean the threads, and reinstall using sealant. Assemble desired nzzle int nzzle hlder using E6000 sealant. The end f the nzzle with the fine mesh screen is t be inserted int the nzzle hlder. Trque 1/2 turn past hand tight. D nt use Tefln sealants n Snw Perfrmance fittings.

Testing the System Nte: fr best results, prime pump befre use T clear air frm the pump and insure that the system is primed: Fill reservir with water apprx ¼ full. Remve tubing frm nzzle (r slenid if slenid used in-line between pump and nzzle) and run tube int separate cntainer. Apply 12 VDC t red pump wire fr apprximately 5 secnds r until fluid flw is cnsistent. Pump is nw primed. Recnnect tubing frm pump utlet t nzzle (r slenid). If using a slenid in between the pump and the reservir: Remve the slenid and place a slid piece f tube between the pump and the reservir and prime the system. Then replace the slenid in between the pump and reservir. Step 1 Test Pump and Mechanical System Discnnect pump frm cntrller. Using a 12 vlt surce, apply pwer t red wire f pump. Pump shuld activate and fluid level in tank shuld g dwn. It is recmmended t als check the nzzle spray pattern while fllwing this prcedure. Als check fr leaks. Crrect Incrrect NOTE: If nzzle is munted lwer then the reservir, a slenid (#40060) must be used t prevent draining. Step 4 Nzzle Munting The nzzle assembly shuld be installed 90 t the directin f airflw. On rund intake tubes, this is 360 arund the tube meaning the nzzle can be munted in any directin. This will ensure maximum cling as the nzzle sprays in a cne pattern. Chse and mark munting lcatin fr nzzle placement. Nzzles can be lcated n the charge tube between the intercler utlet and the intake inlet. Place nzzles at a lcatin where they have an unbstructed spray pattern int the airflw. Remve the selected piece and drill and tap (11/32 pre-drill, 1/8-27 NPT tap) fr ne r tw nzzles. Nte that NPT is a tapered thread, and be cautius nt t ver-tap thin walled pipes. Test fit nzzles int the pipe t ensure a tight fitment. If pump ges n and fluid level desn't g dwn, there is an bstructin in the tube r nzzle.

Variable Cntrller Tuning EGT Cntrl Mde When EGT Cntrl mde is enabled, the cntrller will measure EGTs and bst pressure t calculate the injectin rate. In this mde, a high gain setting will result in a larger injectin rate. The nzzle is munted using its external 1/8 NPT threads. Tighten the nzzle and nzzle hlder assembly ne half turn past finger tight using E6000 t seal the threads. Step 5 Nzzle Cnnectin and Slenid Cnnectin Slenid is flw directinal. Be sure t nte which prt is the INLET/PRESSURE prt (2 r IN) and which is the OUTLET prt (1 r OUT). The main utlet line cming frm the Reservir cnnects t the slenids inlet. The utlet f the slenid cnnects t the inlet f the pump. Measure the distance frm the pump utlet t the nzzle hlder. Cut the ¼ tubing using utility knife. Make cuts are as square as pssible. Ensure there are n kinks in the tubing and insert tubing int quick discnnects until fully seated. Gently pull n tubing t ensure a gd cnnectin. Use tie wraps t help rute tubing and t ensure it desn't cntact mving r ht parts in the engine cmpartment. Have tubing cnnect t quick cnnect fittings at shallw angles. Having an immediate sharp bend may unseat the tubing frm the internal -ring and create a leak. Tggle t Screen 8. Set EGT Cntrl t ON. Tggle t Screen 10. Adjust the gain up t 100. If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity r lwer the gain setting n the mdule. This can be dne by: Using a smaller nzzle(s). Adjusting the gain. T adjust gain dwn, tggle t screen 11. Adjust the gain dwn until engine runs smth with n bucking. Bst Only Mde The cntrller has a bst nly mde. When EGT Cntrl mde is disabled, injectin is a functin f bst pressure nly which is desirable in racing applicatins and day t day driving where mre immediate injectin is desired. Tggle t Screen 8. Set EGT Cntrl t OFF. Tggle t Screen 10. Adjust the gain up t 100. If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity r lwer the gain setting n the mdule. This can be dne by: Using a smaller nzzle(s). Adjusting the gain. T adjust gain dwn, tggle t screen 11. Adjust the gain dwn until engine runs smth with n bucking. Cntinual insertin and remval frm quick cnnect fittings will mar the end f the tubing. Over time the internal gripping teeth may lse their
