(ANNOUNCER)>> OUR STREET/STRIP GAS POWERED SILVERADO IS BACK, THIS TIME READY FOR ITS FINAL GIFT. TODAY ON TRUCK TECH STEP BY STEP HOW TO ON

UPGRADING TO A TURBO CHARGER FOR BIG, BAD DYNO PROVEN POWER.

(LT)>> TODAY IS A DAY WE'VE BEEN WAITING FOR FOR QUITE SOME TIME. THAT'S RIGHT, WE'RE GONNA TAKE OUR 2010 SILVERADO AND GIVE IT ONE FINAL PUSH TO TRANSFORM IT INTO A TURBOCHARGED STREET TERROR, AND WE'RE GONNA SHOW YOU WHAT IT TAKES TO MAKE THIS HAPPEN WITH YOUR LS POWERED GM TRUCK OR SUV.

(JEREMY)>> YEAH FROM THE ONSET OUR GOAL WAS TO MAKE PROJECT WHITE NOIZE A HIGH PERFORMANCE SLEEPER, BUT WE HAD ONE CONDITION. IT NEEDED TO BE USABLE FOR MONDAY THROUGH FRIDAY

COMMUTING, AND HONESTLY EVERY PERFORMANCE MODIFICATION ON THIS TRUCK WE MADE SURE COULD BE DONE IN A TYPICAL GARAGE ON A GIVEN WEEKEND.

(LT)>> CAUSE REALLY THAT'S THE ESSENCE OF MODIFYING YOUR DAILY DRIVER, IT HAS TO BE DRIVABLE.

(JEREMY)>> RIGHT! WE SWAPPED IN A HOTTER CAM TO HANDLE THE ABUSE AND BOOST ABOUT TO COME.

THEN LOWERED HER FOUR INCHES IN THE FRONT AND SIX IN THE REAR FOR THAT SLAMMED LOOK. AND FINALLY A TRANS SWAP TO A PERFORMANCE FOURL-80-E ALONG WITH A BRAKE UPGRADE. AND THAT'S WHERE WE'RE STARTING TODAY, A TRUCK THAT BASICALLY HAS A BULLETPROOF DRIVETRAIN READY FOR SOME MAJOR POWER. AND BY THE END OF THE DAY PROJECT WHITE NOIZE WILL HAVE A TURBO, AND WE WON'T HAVE TO WORRY ABOUT THINGS LIKE BREAKING A DIFFERENTIAL OR BLOWING

UP A TRANSMISSION.

(LT)>> WHEN SHOPPING FOR A TURBO KIT FOR A LATE MODEL SILVERADO, WE FOUND A FEW DIFFERENT OPTIONS. AND HECK WE EVEN CONSIDERED FLIPPING OUR FACTORY EXHAUST MANIFOLDS AND BUILDING A CUSTOM HOT SIDE, BUT THERE'S ONE KIT THAT STOOD OUT FROM THE

CROWD IN TERMS OF VALUE AND QUALITY, AND THAT WAS THE TRICK TURBO STAGE THREE TURBO KIT. BUT WHAT REALLY GOT OUR ATTENTION WAS THIS EXHAUST MANIFOLD. IT'S MADE FROM THICK WALL CAST STAINLESS STEEL THAT'LL WITHSTAND THE EXTREME TEMPERATURES OF A TURBO SYSTEM. IT FEATURES SMOOTH SWEPT RUNNERS AND A TRUE TFOUR FLANGE OPENING FOR THE TURBO, AND THE WASTE GATE PORT IS MOUNTED DIRECTLY UNDERNEATH. NOW THE BEST THING ABOUT A CASE MANIFOLD IS IT RETAINS ITS SHAPE MUCH BETTER THAN A FABRICATED ONE. NOW THE HEART OF THE SYSTEM IS THE 76 MILLIMETER TURBOCHARGER. IT'S GOOD FOR ABOUT 650 TO 700 HORSEPOWER TO THE GROUND. AND BECAUSE IT'S A REASONABLE COMPRESSOR SIZE WELL STILL HAVE DECENT SPOOL AND AMAZING TOP END POWER. THE BOOST IS KEPT UNDER CONTROL BY THIS PRECISION TWO BOLT WASTE GATE, WHICH RECIRCULATES BACK INTO THIS DOWN PIPE. THAT WAY YOU DON'T HAVE THAT ANNOYING WASTE GATE SOUND. IT NOW HAS TWO PORTS FOR FACTORY OTWO SENSORS AND A WIDE BAND. THE KIT ALSO COMES WITH THIS CROSSOVER PIPE, WHICH CONNECTS TO YOUR FACTORY EXHAUST MANIFOLD ON THE DRIVER'S SIDE AND INTO THE BACK OF THE CAST MANIFOLD ON THE PASSENGER SIDE. THE COMPRESSED AIR FLOWS THROUGH THE CHARGE PIPES UP FRONT BEHIND THE GRILL WHERE IT MEETS THE INTERCOOLER. THIS IS A FOUR INCH THICK CORE, WHICH WILL KEEP ALL

THAT COMPRESSED AIR UNDER A NICE, COLD TEMPERATURES. THEY GO THROUGH THIS CHARGE PIPE BEFORE MAKING ITS WAY TO THE ENGINE, WHICH HAS A BLOW OFF VALVE BY TURBO SMART AND A FLANGE FOR YOUR FACTORY MASS AIR FLOW SENSOR. NOW THE BEST PART ABOUT THIS WHOLE KIT IS IT COMES WITH ABSOLUTELY EVERYTHING YOU NEED TO COMPLETE THE INSTALLATION.

ALL THE HOSES, CLAMPS, BOOTS, FITTINGS. IT EVEN HAS SOME THERMAL CONTROL AND AN AIR FILTER. NOW THE ONLY THING YOU'RE RESPONSIBLE FOR ARE SOME FUEL INJECTORS, SOME TUNING, AND CONNECTION TO THE EXHAUST OF YOUR CHOICE. SO NOW WE KNOW ALL THE PARTS IT TAKES TO MAKE UP

A COMPLETE TURBO SYSTEM, BUT HOW DO ALL THOSE PARTS WORK TOGETHER? WELL WE'RE ABOUT TO SHOW YOU. A TURBO CHARGER IS USED TO FORCE AIR INTO AN ENGINE FOR MORE HORSEPOWER, BUT UNLIKE A SUPERCHARGER, WHICH IS DRIVEN BY A BELT, A TURBO USES FREE ENERGY FROM THE EXHAUST. THE SPENT GASES SPIN A TURBINE, WHICH SPINS A COMPRESSOR ON THE OTHER SIDE OF THE TURBO. IT SUCKS IN FRESH AIR AND FORCES IT INTO THE ENGINE. THE TURBINE AND COMPRESSOR ARE CONNECTED BY A SINGLE SHAFT THAT RIDES ON BUSHINGS OR BEARINGS. CERTAIN TURBO RACE APPLICATIONS CAN BUILD UPWARDS OF 50 POUNDS OF BOOST PRESSURE. WHAT WOULD HAPPEN IF 100 PERCENT OF THE EXHAUST GAS THAT LEFT THE ENGINE WE'RE ALLOWED TO

SPIN THE TURBOCHARGER? WELL THE AIR FLOW GOES UP, BOOST PRESSURE WILL SKYROCKET, AND YOU'LL PROBABLY SPLIT THE BLOCK IN HALF, OR AT THE VERY LEAST THROW A COUPLE OF RODS OUT THE SIDE. AND I DON'T KNOW ABOUT YOU, BUT FOR ME THAT'S

A PRETTY BAD DAY. SO TO PREVENT THIS FROM HAPPENING AND CONTROL BOOST LEVEL, TURBO KITS INCLUDE A WASTE GATE. IT'S BASICALLY A VALVE THAT WILL ALLOW A CERTAIN AMOUNT OF GAS TO BYPASS THE TURBO CHARGER TO REGULATE THE BOOST PRESSURE. LET'S SAY FOR EXAMPLE THE BOOST PRESSURE IS TOO HIGH. WELL IN THAT SCENARIO THE WASTE GATE WILL OPEN UP AND THE EXHAUST GAS IS ALLOWED TO EXIT TO THE ATMOSPHERE RATHER THAN SPINNING THE TURBO. SO THE TURBO SLOWS DOWN AND BOOST PRESSURE COMES DOWN AS WELL.

NOW ON THE OTHER HAND IF YOUR BOOST PRESSURE IS TOO LOW, THE WASTE GATE WILL REMAIN SHUT AND FORCE ALL

OF THE EXHAUST GAS UP INTO THE TURBOCHARGER. BOOST PRESSURE WILL COME UP AS THE TURBO SPINS FASTER. NOW AS YOU'RE DRIVING AROUND THE WASTE GATE WILL BE CONSTANTLY OPENING AND SHUTTING TO MAINTAIN THAT PERFECT THRESHOLD OF BOOST LEVEL. IT'S SET BY THE TYPE OF SPRINGS THAT ARE INSIDE BUT BASICALLY THAT'S HOW THEY WORK. NOW AS YOU CAN SEE, WASTE GATES ARE PRETTY DARN IMPORTANT. NOW ANYBODY WHO'S SEEN A CAR MOVIE HAS PROBABLY HEARD THE ONE SOUND THAT'S MOST COMMONLY ASSOCIATED WITH THE TURBO SYSTEM, AND THAT IS THE BLOW OFF VALVE.

BUT WHAT EXACTLY DOES A BLOW OFF VALVE DO? WELL PICTURE THIS. AS YOU GO INTO A WIDE OPEN THROTTLE RUN THERE'S A TON OF AIR THAT'S BEING PUMPED INTO THE ENGINE, BUT AT THE END OF THAT RUN THE THROTTLE PLATES CLOSE SUDDENLY AND THAT AIR HAS NO WHERE TO GO. SO A BLOW OFF VALVE IS INSTALLED IN THE CHARGE PIPE TO RELIEVE ALL THAT EXTRA PRESSURE WHEN YOU RAPIDLY DECELERATE. AND WHEN WE COME BACK WE'RE GONNA GET PROJECT WHITE NOIZE TORN DOWN, READY FOR IT'S TURBO.

(ANNOUNCER)>> NEXT PROJECT WHITE NOIZE IS ABOUT TO GET LOUDER.

(LT)>> OUR TURBO INSTALLATION BEGINS WITH

FIRST DISASSEMBLING THE EXHAUST SYSTEM, STARTING WITH OUR MODIFIED TRANS CROSS MEMBER, FOLLOWED BY THE STOCK EXHAUST. THIS WILL ALSO GET REPLACED. WE REMOVE THE ENTIRE THING FROM FRONT TO REAR.

(JEREMY)>> UP IN THE ENGINE COMPARTMENT WE'LL REMOVE SMALL PARTS, LIKE THE ENGINE COVER, INTAKE TUBE, FACTORY AIR FILTER HOUSING, ALL TO GET TO THE PASSENGER SIDE EXHAUST MANIFOLD.

THE PLUG WIRES AND DIP STICK ARE REMOVED, AND OURS WAS SO RUSTED IN WE HAD TO CUT IT OFF. WITH ALL THE BOLTS REMOVED, THE MANIFOLD COMES OUT AND CAN HIT THE SCRAP PILE. THE NEW CAST STAINLESS MANIFOLD LOWERS INTO PLACE TEMPORARILY FOR MOCK UP. YOU HAVE TO BEND THE A/C LINE OUT OF THE WAY TO MAKE ROOM FOR THE WASTE GATE. THIS IS AN IMPORTANT STEP, AND YOU CAN EASILY KINK THE PIPE IF YOU GO TOO FAR. SO I'LL TAKE MY TIME AND CHECK CLEARANCE AS I GO. WE'RE LOOKING FOR ABOUT AN INCH OF ROOM.

(JEREMY)>> LOWER THE DOWN PIPE INTO PLACE. THEN THE TURBO.

CONNECT THE VBAND AND SET THE TURBO ONTO THE FLANGE,

AGAIN TEMPORARILY. ONCE YOU KNOW EVERYTHING WILL FIT, REMOVE IT ALL. INSTALL THE GASKETS AND PERMANENTLY BOLT

ON THE MANIFOLD.

(LT)>> BEFORE WE INSTALL OUR WASTE GATE, WE NEED TO SET THE INITIAL BOOST LEVEL, AND THAT'S CONTROLLED BY SPRINGS.

NOW WHEN YOU BUY A WASTE GATE, IT COMES WITH A

VARIETY OF DIFFERENT SPRINGS AT DIFFERENT TENSIONS, WHICH ARE COLOR COATED, AND EACH ONE REPRESENTS A DIFFERENT BOOST LEVEL. DEPENDING ON HOW MANY SPRINGS YOU RUN, YOU CAN GO AS LITTLE AS ONE AND A HALF POUNDS OF BOOST ALL THE WAY UP TO 25. WE WANT TO RUN ABOUT 10 POUNDS OF BOOST, AND FOR US THAT MEANS A SINGLE GREEN SPRING IS INSTALLED.

(JEREMY)>> THE WASTE GATE ATTACHES TO THE MANIFOLD WITH TWO BOLTS.

(LT)>> TO INSULATE THE PIPE AND PROTECT OUR WIRES AND COOLANT LINES I'LL WRAP THE DOWN PIPE WITH THIS DEI TITANIUM EXHAUST WRAP. THAT WILL KEEP THE ENGINE BAY OF OUR SILVERADO COOLER AND WE WON'T HAVE TO WORRY ABOUT MELTING ANYTHING. NOW WE CAN INSTALL THE DOWN PIPE AND THE TURBO FOR GOOD. THE TRICK TURBO INTERCOOLER IS NEXT. IT SIMPLY MOUNTS IN FRONT OF THE RADIATOR WITH THE SUPPLIED BRACKETS, ATTACHING TO THE CORE SUPPORT AT THE TOP AND THE BOTTOM. I'LL MARK AND DRILL A HOLE THROUGH THE PLASTIC TO ALLOW THE INTERCOOLER PIPE TO PASS THROUGH, MAKE CONNECTIONS ON THE DRIVER'S SIDE TO THE ENGINE, AND THE COLD SIDE IS DONE.

(JEREMY)>> MAN LOOKS LIKE YOU'VE ABOUT GOT IT.

(LT)>> YEAH IT'S ALL MOCKED UP. YOU KNOW THIS KIT WENT TOGETHER SUPER EASY. THE ONLY THING I DON'T LIKE THOUGH IS ALL

THIS POLISHED ALUMINUM. IT'S JUST KINDA FLASHY. THIS TRUCK'S SUPPOSED TO BE A SLEEPER. ANYTHING WE CAN DO ABOUT THAT?

(JEREMY)>> YEAH MAN, I AGREE WITH YOU THERE, ABSOLUTELY, WE CAN PREP THIS ALUMINUM,

THROW A NICE SATIN FINISH ON THERE. THAT WAY AT LEAST WHEN YOU POP THE HOOD NOTHING'S JUST BANGING OUT AT YOU. I THINK IT'LL LOOK REALLY NICE THAT WAY.

(LT)>> ALRIGHT LET'S TEAR DOWN.

(JEREMY)>> ABSOLUTELY.

(LT)>> THE TURBO CAN NOW PUMP AIR TO THE ENGINE, BUT LUBRICATION IS IMPORTANT TOO. I'LL DRAIN AND REMOVE THE OIL PAN FOR THE NEXT BIT OF MODIFICATION. ALL TURBO CHARGERS USE PRESSURIZED OIL FROM THE ENGINE TO PROVIDE BOTH LUBRICATION AND COOLING, BUT WE NEED A WAY TO GET THAT OIL FROM THE TURBO CHARGER BACK INSIDE THE ENGINE. SO WE'RE GONNA USE THE PROVIDED DRILL AND TAP TO PUT A THREEEIGHTHS PIPE FITTING IN THE SIDE OF THE OIL PAN TO GIVE THAT OIL A PLACE TO GO. NOW YOU CAN DO THIS OPERATION WITH THE PAN STILL ON THE VEHICLE, BUT THE ONLY WAY TO ENSURE 100 PERCENT OF THE METAL SHAVINGS ARE OUT OF THE PAN IS TO TAKE IT OFF. AND BESIDES, OUR TRUCK IS A TWO WHEEL DRIVE. SO IT ONLY TOOK A FEW MINUTES TO REMOVE THE OIL PAN ANYWAY.

(JEREMY)>> ALUMINUM IS ONE OF THE HARDEST MATERIALS FOR PAINT TO ADHERE TO. THE HARD SURFACE IS TOUGH TO BREAK THROUGH, GETTING THAT TOOTH YOU NEED FOR THE PAINT TO BITE INTO FOR GOOD ADHESION. NOW SANDING WITH A RED SCUFF PAD, IT LOOKS LIKE IT'S BREAKING THE SURFACE BUT IT'S NOT. IT'S BASICALLY JUST ENOUGH TO GET THE SHINE OFF THE PIPE. NOW THIS IS WHERE GUYS USUALLY RUN INTO TROUBLE AND WHY THEIR PAINT STARTS PEELING OFF

ALUMINUM DOWN THE ROAD. THE RED SCUFF PAD JUST ISN'T AGGRESSIVE ENOUGH. NOW I COULD CHEMICALLY WASH THESE PARTS USING

ALUMINUM SPECIFIC PRIMER OR EVEN SAND BLAST THEM TO GET GOOD ADHESION, BUT THAT'S KIND OF A LOT TO DEAL WITH WHEN YOU JUST HAVE A FEW SMALL TUBES YOU WANT TO PAINT, BUT THERE'S A FEW EASY STEPS YOU CAN TAKE TO GET THE PAINT TO STICK. ONE THING WITH ALUMINUM IS IT NEEDS TO BE CLEAN. AND LIKE YOU JUST SAW, LT HAD HIS GREASY HANDS ALL OVER THESE THINGS. SO THE FIRST STEP IS TO WASH WITH AN AGGRESSIVE CLEANER LIKE ACETONE. NEXT I'LL SAND THE TUBES WITH 180 GRIT SAND PAPER.

I KNOW THAT SEEMS AGGRESSIVE BUT FOR ALUMINUM IT'S NOT. IT'S JUST ENOUGH TO BREAK THE SURFACE TO GET US GOOD ADHESION.

NEXT IS ONE OF THE MOST IMPORTANT STEPS, AND THAT'S SELF ETCHING PRIMER. IT'S A MIX OF PHOSPHORIC ACID AND ZINC.

THE WAY IT WORKS IS THAT THE ACID FORCES THE ZINC INTO THE TOP OF THE METAL AND IT'S PURELY A SURFACE COATING. SO WE ONLY NEED ONE COAT. ONCE WE LET THAT FLASH FOR ABOUT 20 OR 30 MINUTES, WE CAN FOLLOW THAT UP WITH SOME VHT BLACK WRINKLE FINISH. THIS WILL GIVE LT THAT SLEEPER LOOK HE'S GOING FOR UNDER THE HOOD.

(LT)>> AND WHILE IT'S DRYING I CAN REINSTALL THE OIL PAN. THEN SANDWICH THE OIL COOLER ADAPTER, WHICH WILL FEED OIL TO THE TURBOCHARGER.

(ANNOUNCER)>> NEXT FORCED INDUCTION CALLS FOR A MASSIVE EXHAUST.

(LT)>> WE NEEDED A WAY TO GET THE EXHAUST GAS FROM OUR TRICK TURBO DOWN PIPE TO THE BUMPER ON OUR SILVERADO. SO WE WENT TO MAGNAFLOW AND PICKED UP AN EXHAUST FOR A SIX LITER POWERSTROKE OF ALL THINGS. I'VE GOT SOME STAINLESS STEEL WIRE IN THE MIG AND WE'RE GONNA SHOW YOU GUYS HOW TO MAKE THIS ALL WORK.

BUT WHY DID A CHOOSE A MID 2000'S FORD KIT? I KNEW THE SIX LITER POWERSTROKE KIT HAD DUAL EXHAUST, WHICH LEFT PLENTY OF PIPE TO CUT FOR OUR SINGLE SYSTEM. AND FOUR INCHES WILL GUARANTEE US MINIMUM BACK

PRESSURE ON THE TURBO.

(JEREMY)>> VIBRANT PERFORMANCE VBAND CLAMPS WILL GIVE US LEAK FREE CONNECTIONS AND QUICK REMOVAL IF WE NEED IT. THIS MAGNAFLOW MUFFLER IS A STRAIGHT THROUGH DESIGN AND WILL GIVE OUR TRUCK A MELLOW TONE WITHOUT SACRIFICING FLOW.

(LT)>> WELL THERE YOU. THAT'S WHAT IT TAKES TO GET A POWERSTROKE EXHAUST ON A SILVERADO. NOW WE HAVE TO ADD SOME HANGERS AND FINISH WELD IT, BUT THIS BABY'S DONE. [ WELDER CRACKLING ]

(JEREMY)>> SO FAR WE'VE GOT INDUCTION TAKEN CARE OF, AND OUR FOUR INCH EXHAUST WILL PROVIDE A PATH FOR THAT COMBUSTION TO ESCAPE. SO NOW IT'S TIME TO ADDRESS FUEL AND SPARK. THESE ARE MSD PRO POWERED COILS, AND THEY'LL ACTUALLY SPARK MULTIPLE TIMES AT LOWER RPM FOR A GREATER COMBUSTION.

YOU'LL GET BETTER THROTTLE RESPONSE AND HIGHER RPM PERFORMANCE. INCREASED AIR IS GOING TO NEED MORE FUEL. IF WE WERE TO KEEP THESE STOCK INJECTORS THE TRUCK WOULD START AND IT WOULD RUN BUT AS SOON AS YOU GOT INTO BOOST YOU'D HAVE PROBLEMS. THE ENGINE WOULD RUN LEAN AND POTENTIALLY

GRENADE ON YOU. SO WE WENT TO SUMMIT RACING AND PICKED UP THESE DEATSCHWERKS 72 POUND INJECTORS. THEY HAVE A 93 PERCENT MAXIMUM DUTY CYCLE, HAVE A NICE FLOW PATTERN SO YOU STILL HAVE A GOOD IDLE AND

EASY TUNING, AND THEY'LL ALSO WORK WITH E-85 FUEL. AND TO GO ALONG WITH OUR HOTTER COILS WE'RE ALSO GOING TO THROW ON AN MSD LS COIL POWER UPGRADE HARNESS. IT FEATURES A HIGH CURRENT RELAY AND WILL DELIVER MORE RELIABLE POWER THAN THE OE HARNESS CAN PROVIDE.

(LT)>> SUMMIT RACING SENT US THIS VIBRANT PERFORMANCE FOUR QUART RECIRCULATING OIL CATCH CAN. ITS JOB IS TO SEPARATE OIL FROM THE CRANK CASE VAPORS

SO THEY DON'T GET SUCKED BACK INTO THE ENGINE, SOMETHING WE RECOMMEND FOR ANY TURBO APPLICATION.

(JEREMY)>> YOU KNOW THE OLD SAYING RUST NEVER SLEEPS? WELL EVAPORUST IS A WATER SOLUBLE SOLUTION THAT WAKES UP RUST PARTICLES AND REMOVES THEM FROM JUST ABOUT ANYTHING. IT'S SAFE ON THE ENVIRONMENT AND WILL NOT HARM ALUMINUM, COPPER, BRASS, PLASTIC, OR VINYL. THESE PLIERS WERE FOUND HIDDEN IN THE YARD ALONG WITH SOME WIRE CUTTERS WE'VE BEEN SOAKING FOR A FEW HOURS. CHECK IT OUT, NO MORE RUST, AND YOU CAN POUR IT BACK INTO THE BOTTLE AND USE IT AGAIN AND AGAIN. GO TO EVAPORUST DOT COM FOR MORE.

(LT)>> YOU WOULDN'T BUTTER YOUR TOAST WITH A SCREW DRIVER, SO WHY USE A KITCHEN PAPER TOWEL

IN YOUR GARAGE? SCOTT GLASS SHOP TOWELS ARE THE RIGHT TOOL FOR THE RIGHT JOB, WHETHER IT'S FOR SHINNING UP A CHROME EXHAUST TIP OR CLEANING A STUBBORN WINDSHIELD. SCOTT GLASS SHOP TOWELS REDUCE LINT AND STREAKING. IT'S GREAT FOR GLASS, WINDSHIELDS, CHROME, AND MIRRORS. AVAILABLE AT YOU FAVORITE AUTOMOTIVE RETAILER.

(JEREMY)>> LOOKING FOR A REPLACEMENT GRILL FOR YOUR CLASSIC TO NEWER MODEL PICK UP? WELL LMC TRUCK HAS A VAST INVENTORY OF BOTH MOLDED AND BILLET ALUMINUM GRILLS FOR FORD, GM, AND DODGE '47 AND UP. THIS IS A FACTORY REPRODUCTION GRILLE SHELL FOR A '91 THROUGH '93 RAM PICKUP. IT SELLS FOR $140 BUCKS PLUS SHIPPING, AND WILL REALLY BRIGHTEN UP THE FRONT OF YOUR TRUCK.

FOR YOUR APPLICATION CHECK OUT LMC TRUCK DOT COM.

(ANNOUNCER)>> WITH EVERYTHING BUTTONED UP, OUR TURBO SILVERADO IS READY FOR SOME TUNAGE. THE DYNO IS NEXT!

(JEREMY)>> WE'RE BACK ON TRUCK TECH, AND IT'S

JUDGEMENT DAY FOR PROJECT WHITE NOISE. WE INVITED ALEX PIETZ FROM PIETZ PERFORMANCE TUNES BACK TO THE SHOP TO MAKE SOME REQUIRED ADJUSTMENTS TO THE FIVE POINT THREE'S COMPUTER SINCE WE ADDED A TURBO, DID A CAM SWAP, AND THREW ON SOME FOUR INCH EXHAUST. BUT BEFORE WE GET TO THE NUMBERS, ALEX AND LT NEED TO DRIVE THE TRUCK AROUND TO COLLECT DATA FOR ALEX TO CRAFT A CUSTOM TUNE.

(ALEX)>> SO HOW'D THE INSTALL GO?

(LT)>> WELL THE TURBO INSTALL WENT GREAT. EVERYTHING PRETTY MUCH BOLTED ON. YOU KNOW I COULDN'T BE HAPPIER. I'VE INSTALLED A LOT OF AFTERMARKET PARTS IN MY TIME, AND YOU WOULDN'T BELIEVE THE STUFF THAT JUST DOESN'T FIT. BUT THIS KIT, THE TRICK TURBO INSTALLED PERFECTLY. EVERYTHING BOLTED RIGHT UP, LINED UP, SEALED, NO

LEAKS, AND I'LL TELL YOU WHAT, MY RIGHT FOOT IS GETTING A LITTLE BIT ANXIOUS. TALK TO ME ABOUT CUSTOM TUNING. HOW IMPORTANT IS IT FOR A VEHICLE LIKE TO HAVE A CUSTOM TUNE?

(ALEX)>> WELL WITHOUT A CUSTOM TUNE YOU'RE DEFINITELY NOT GOING TO HAVE PRECISE FUELING. DRIVABILITY'S PROBABLY GOING TO SUFFER SOME. IDLE OR OFF IDLE SITUATIONS ARE NOT GONNA BE AS DESIRABLE AS YOU'D WANT THEM. YOUR AIR/FUEL RATION COULD BE OFF FROM WHAT YOU WANT IT TO BE AND IF THAT HAPPENS, ESPECIALLY ON THE LEAN SIDE, THAT COULD CAUSE POTENTIAL ENGINE FAILURE.

(LT)>> SO WITH A BASE LINE DIALED IN, WE'LL GET IT STRAPPED TO THE DYNO AND START FOCUSING ON WIDE OPEN THROTTLE.

THE TUNE IS PRETTY CLOSE, SO LET'S DO A PULL. [ ENGINE REVVING ]

(LT)>> 426 AND 404.

(JEREMY)>> SOUNDED REALLY GOOD, GOOD AND STRONG.

(ALEX)>> WELL IT LOOKS LIKE WHAT WE NEED TO DO FIRST IS ADJUST THE MAF TRANSFER FUNCTION TO MAKE THE AFR EXACTLY WHAT WE WANT IT TO BE. SO IT'S JUST A LITTLE OFF RIGHT NOW, NOT BY MUCH, TWO OR THREE PERCENT. WE'LL MAKE SOME ADJUSTMENTS ON THE MAF CURVE. WE'RE A LITTLE RICH RIGHT HERE, ABOUT 10, NINE TO ONE AFR. WHICH YOU WANT TO BE ABOUT 11-THREE TO ONE THROUGHOUT THE RUN. AS YOU SEE HERE WE GOT CLOSER TO OUR TARGET RIGHT AT ABOUT 4,600 RPM, AND THEN WE STARTED TAPERING OFF GOING BACK A LITTLE RICH AGAIN. SO I'M GONNA MAKE SOME ADJUSTMENTS IN THIS AREA OF THE MAF CURVE AND THIS AREA OF THE MAF CURVE. AND THEN MAYBE ADJUST SPARK ADVANCE A LITTLE BIT. WE'RE GONNA TRY TO INCREASE THE BOOST SOME AS

WELL WITH THE BOOST CONTROLLER AND SEE WHAT WE CAN GET FOR POWER. ON THAT LAST PULL THE MAX BOOST WE SAW WAS ABOUT FIVE PSI. SO WE'RE GONNA TRY TO INCREASE THE BOOST THIS TIME TO GET SOME MORE POWER OUT OF IT. [ ENGINE REVVING ]

(LT)>> BETWEEN THE MINOR CHANGES IN FUEL MIXTURE,

TIMING, AND BOOST, WE'VE ALREADY GAINED AN ADDITIONAL 18 HORSEPOWER. NOT BAD AT ALL, AND ALEX IS GOING TO DIVE DEEPER

INTO THAT HP TUNER SOFTWARE AND KEEP MAKING ADJUSTMENTS. WITH THE COMPUTER REFLASHED WE'LL

DO ANOTHER PULL. THIS TIME WE'RE UP TO 481, GAINING YET

ANOTHER 35 HORSEPOWER.

AFTER ANOTHER ADJUSTMENT TO THE BOOST CONTROLLER WE'LL BE RUNNING A TOTAL OF EIGHT POUNDS OF BOOST. AND ONE OF THE LAST TWEAKS ALEX HAS MADE IS TO THE

VARIABLE CAM TIMING, AND WE THINK THIS RUN IS GONNA BE RIGHT IN THE SWEEP SPOT.

(JEREMY)>> AND IT SURE WAS!

ALEX MANAGED TO GET 498 TO THE WHEELS OUT OF THIS BOY, AND WE'LL CALL IT 500.

(LT)>> GUYS WE DID PRETTY AWESOME. WE'VE GOT 500 HORSE AT THE WHEELS FROM A STOCK BOTTOM END FIVE POINT THREE.

(JEREMY)>> YEAH IT JUST SHOWS WHAT AXLE FROM PIETZ PERFORMANCE CAN DO WITH A HP TUNER SOFTWARE.

(ALEX)>> ABSOLUTELY, IT WAS A PLEASURE BEING HERE AND I CAN'T WAIT TO SEE WHAT THIS THING DOES AT THE TRACK.

(JEREMY)>> YEAH MAN, WE APPRECIATE YOU

COMING IN FOR US.

(ALEX)>> NO PROBLEM.

(LT)>> ALRIGHT, LET'S GET THIS THING UNHOOKED.

(JEREMY)>> LET'S DO IT.
