Hemi With a Power Adder

(NARRATOR)>> TODAY ON ENGINE POWER WE TAKE THIS 2017 JEEP GRAND CHEROKEE SRT EIGHT TO A NEW POWER LEVEL WITH A BOLT ON SUPERCHARGER FROM PROCHARGER.

(MIKE)>> WELCOME TO ANOTHER EPISODE OF ENGINE POWER. TODAY WE HAVE SOME WELL KNOWN FRIENDS IN THE SHOP WHO SPECIALIZE IN CENTRIFUGAL SUPERCHARGERS AND THE COMPONENTS IT TAKES TO MAKE BIG HORSEPOWER AND TORQUE WITH A STRAIGHT FORWARD INSTALLATION USING BASIC HAND TOOLS. NOW TODAY'S MAIN FOCUS IS ON THE LATE MODEL HEMI ENGINE, AND PROCHARGER HAS THE WHOLE FLEET OF CARS, TRUCKS, AND JEEPS COVERED, WHETHER IT'S THE FIVESEVEN, THE SIXONE, OR THE MONSTER SIX POINT FOUR LITER POWERHOUSE.

(PAT)>> THE GEN THREE HEMI COMES IN A VARIETY OF VEHICLES, RAM TRUCKS, CHALLENGERS, CHARGERS, 300-C'S, AND EVEN JEEP PRODUCTS LIKE THIS GRAND CHEROKEE SRT EIGHT, WHICH HAS THE SIX POINT FOUR LITER THAT PRODUCES 475 HORSEPOWER AND 470 POUND FEET OF TORQUE. IT DOESN'T MATTER WHAT THE ENGINE COMES IN. IT'S A GREAT PLATFORM THAT RESPONDS TO BIG BOOST FROM PROCHARGER SUPERCHARGERS, AND THEY ARE THE LEADER IN HEMI KITS HANDS DOWN. THE SRT EIGHT CHEROKEE DESERVES RESPECT. IT'S A 5,291 POUND FOUR DOOR SUV THAT SPORTS A SIX POINT FOUR LITER HEMI, WHICH HAS 392 CUBIC INCHES OF DISPLACEMENT, AND EIGHT SPEED AUTO, AND ALL WHEEL DRIVE. THE WHEEL SIZES ARE 20 BY 10 ON ALL FOUR CORNERS. THE BRAKES ARE BREMBOS FROM THE FACTORY AND MEASURE 15 INCHES UP FRONT AND 13.8 INCHES OUT BACK. WALT SIPP IS A BIG PART OF THE TESTING AND DEVELOPMENT TEAM. HE WAS THERE WHEN WE MADE BIG POWER WITH A 2016 MUSTANG GT LAST YEAR, AND WILL FILL US IN ON THIS KIT TODAY. WALT WHY DOES PROCHARGER SUPPORT THE HEMI ENGINE SO STRONGLY?

(WALT)>> WELL PAT I'M GLAD YOU ASK. DODGE, CHRYSLER, AND JEEP HAS BEEN USING THE HEMI SINCE 2004 IN THE TRUCKS, AND ALSO IN CARS WITH THE MAGNUM AND THE CHARGER STARTING IN 2005. THERE'S LOTS OF HEMI VEHICLES THAT WE CAN OFFER KITS FOR.

(PAT)>> WITH OUR INSTALL TODAY BEING A GRAND CHEROKEE SRT EIGHT WHAT OTHER JEEP PLATFORMS DO YOU SUPPORT?

(WALT)>> KITS FOR 2011 THROUGH 2017 FIVESEVEN GRAND CHEROKEE, '06 TO 2010 SRT EIGHT GRAND CHEROKEE AS WELL AS THREE POINT SIX 2012 AND UP WRANGLER.

(PAT)>> NOW ARE THERE ANY HEMI POWERED THINGS YOU DON'T OFFER A KIT FOR?

(WALT)>> WE DO NOT. WE ACTUALLY FIT ALL THE CURRENT HEMI PLATFORM VEHICLES WITH A KIT COMING SOON FOR THE 2,500 TRUCKS.

(PAT)>> TELL ME A LITTLE BIT ABOUT THE KIT WE'RE GONNA BE INSTALLING TODAY.

(WALT)>> WELL THE KIT THAT WE'RE INSTALLING TODAY IS OUR HO HIGH OUTPUT INTERCOOLED SYSTEM FOR THIS JEEP. USUALLY THAT KIT UTILIZES OUR PONESC DASH ONE SUPERCHARGER. WE'RE ACTUALLY GONNA BE USING THE PONEX ON THIS, WHICH SHOULD DELIVER A 200 TO 2015 HORSEPOWER GAIN.

(PAT)>> SO WHAT ARE THE OPTIONS THAT ARE AVAILABLE FOR THE HEAD UNIT?

(WALT)>> THIS KIT WILL BE USING OUR NEW PONEX SUPERCHARGER, WHICH WILL GIVE YOU AN ADDITIONAL 10 TO 15 HORSEPOWER OVER THE 200 TO 215 HORSEPOWER GAIN THAT WE STATED INITIALLY.

(PAT)>> NOW IS THIS KIT UPGRADABLE?

(WALT)>> WE HAVE A RACE INTERCOOLER OPTION UPGRADE AS WELL. WE CAN ALSO FIT SUPERCHARGERS UP TO OUR FONEA-94 SUPERCHARGER, WHICH IS AGAIN A NINE INCH HOUSING SIMILAR TO THESE BLOWERS BUT WILL SUPPORT 1,200, 1,300 HORSEPOWER. SO YEAH, DEFINITELY A LOT OF OPTIONS THAT YOU CAN GET ON THESE KITS.

(PAT)>> ARE COATINGS OPTIONAL?

(WALT)>> THEY ARE. THIS KIT IS USING OUR BLACK POWDER COATED OPTION. SATIN FINISHED IS THE STANDARD, BUT AS I MENTIONED BLACK'S AN OPTION AS WELL AS A POLISHED FINISH IF YOU WANT TO DRESS IT UP A LITTLE BIT TOO.

(PAT)>> NOW AT THE BOOST THAT THIS KIT IS PUTTING OUT IS IT COMPATIBLE WITH ALL OF THE STOCK COMPONENTS ON THE VEHICLE?

(WALT)>> THAT'S A GREAT QUESTION. WE GET A LOT OF CUSTOMERS THAT DO ASK US THAT EXACT QUESTION. THE BEAUTY IS, AS YOU MENTIONED EARLIER, WE ARE THE HEMI LEADER. WE'VE BEEN DOING THIS LONGER THAN ANYBODY. OUR SUPERCHARGER KIT AND THE BOOST LEVEL WE OFFER IS ABSOLUTELY SAFE FOR A GUY ON A COMPLETELY BONE STOCK APPLICATION WITH NO OTHER WORK NEEDED. THE SEVEN PSI WE DELIVER AND THAT HORSEPOWER GAIN, WILL BE ABLE TO DO THAT FOR MANY, MANY MILES.

(MIKE)>> SPEAKING OF STOCK, LET'S GO SEE WHAT THIS THING IS CAPABLE OF. WE'LL BE DOING A ZERO TO 60 TEST BEFORE AND AFTER THE PROCHARGER IS INSTALLED. THE FACTORY GAUGE IS ABLE TO REGISTER THE TIME. IT'S DISPLAYED IN THE UPPER LEFT HAND CORNER.

NOT TOO SHABBY, THAT IS PRETTY IMPRESSIVE. FOUR POINT EIGHT SECONDS ZERO TO 60 IN A BIG SUV LIKE THIS, CAN'T COMPLAIN.

(PAT)>> NO BUT WE WILL IMPROVE IT WHEN MIKE GETS BACK, STAY WITH US.

(MIKE)>> WELCOME BACK TO THE PROCHARGER INSTALL ON A SIX POINT FOUR LITER HEMI POWER PLANT. NOW THE VERY FIRST STEP OF THE INSTALL IS TO LOCATE THE INSTALLATION GUIDE. NOW THIS THING IS SUPER DETAILED AND IT'LL HELP YOU OUT IN A BIG, BIG WAY TO SPEND A LITTLE TIME AND GET FAMILIAR WITH IT. IT LETS YOU KNOW WHAT TOOLS AND SUPPLIES YOU'LL NEED, ALONG WITH HOW TO SEND AND RECEIVE THE TUNE FILES FROM PROCHARGER. THEN BASICALLY IT GUIDES YOU THROUGH THE INSTALL WITH COLOR PHOTOS OF EACH STEP. NOW WE'RE NOT GOING TO SHOW YOU EVERY ONE, BUT WE WILL FOCUS ON THE LARGER PARTS AND PROCEDURES TO GET THIS SIX POINT FOUR LITER HEMI OVER 700 HORSEPOWER. WE'LL START BY GETTING THE BIG STUFF OUT OF THE WAY, LIKE THIS FACTORY AIR BOX. NEXT TO COME OFF IS THE BIGGEST OF THE JOB, THE ENTIRE FRONT FASCIA. TAKE YOUR TIME WITH THIS. YOU DON'T WANT ANY DAMAGE TO THE PAINT SURFACE OR THE RETAINING CLIPS. THE NEXT ITEM IS DECENT IN SIZE TOO. THE WINDSHIELD WASHER RESERVOIR IS REMOVED AS WELL.

(PAT)>> THE NEXT STEP IS TO PREVENT THE FACTORY PRESSED ON HARMONIC BALANCER FROM ROTATING DUE TO THE ADDITIONAL FORCE OF THE SUPERCHARGER BELT, BUT PROCHARGER PROVIDES A CRANK PINNING KIT TO MAKE IT A SIMPLE TASK. IT HAS A DRILL FIXTURE, A HEX BOLT TO HOLD THE FIXTURE IN PLACE, A QUARTER INCH HIGH SPEED STEEL DRILL, AND A QUARTER INCH STEEL DOWEL PIN. NOW IT IS DOWN TIGHT IN THE ENGINE BAY. SO WE WON'T BE ABLE TO SHOW YOU THE STEPS, BUT HERE IS A LOOK AT HOW THE TOOL WORKS. THE JIG IS PLACED ON THE BALANCER AND SECURED WITH THE HEX BOLT, AND THEN TAPE IS PLACED ONE AND FIVEEIGHTHS FROM THE TIP OF THE DRILL BIT. SIMPLY DRILL UNTIL THE TAPE MEETS THE EDGE OF THE FIXTURE. REMOVE THE TOOL AND CLEAN OUT THE HOLE AND INSERT THE DOWEL. IT'S THAT EASY!

(MIKE)>> THE TOP RADIATOR HOSE HAS TO BE REMOVED. THE SERPENTINE BELT IS PULLED BY ROTATING THE TENSIONER COUNTER CLOCKWISE. NOW THE 16 MILLIMETER BOLT IS REMOVED TO ALLOW THE TENSIONER TO COME OFF. THE IDLER PULLEY IS REMOVED, ALONG WITH THE LOWER BOLT HOLDING THE BRACKET. THREE MORE FASTENERS COME OUT, WHICH IS WHERE THE SUPERCHARGER'S MAIN BRACKET WILL ATTACH TO. PROCHARGER'S BRACKET ASSEMBLIES ARE MADE FROM 60-61 BILLET ALUMINUM AND CNC'ED TO EXACT TOLERANCES. NOW THE ENGINEERS DESIGNED THESE NOT ONLY FOR THE UTMOST STRENGTH, BUT ALSO TO BE ABLE TO UPGRADE TO A BIGGER SUPERCHARGER WITHOUT THE NEED OF A NEW BRACKET OR MOUNTING LOCATIONS. IT'S INSTALLED STARTING WITH THE TOP LEFT SPACER AND SOCKET HEAD CAP SCREW. THEN WORK YOUR WAY TO THE DIFFERENT MOUNTING LOCATIONS. THERE ARE FOUR. THE BRACKET ALSO HOUSES NEW IDLER PULLEYS.

(PAT)>> LIKE WALT MENTIONED EARLIER, THE PONESCONE IS WHAT COMES STANDARD WITH THIS HO KIT, AND IT WILL SUPPORT 825 HORSEPOWER. WE DECIDED TO UPGRADE TO THE NEWLY RELEASED PONEX UNIT, WHICH WILL GIVE 10 TO 15 HORSEPOWER EXTRA AT THE SAME BOOST LEVEL AS THE PONESCONE. THAT'S BECAUSE IT HAS A MORE EFFICIENT IMPELLER AND COMPRESSOR DESIGN. THE DRAIN LINE MAKES FOR EASY SERVICE WHEN THE OIL IN THE CHARGER NEEDS TO BE REPLACED. IT ACCEPTS ONE BOTTLE OF PROCHARGER'S OIL. THEY SEND FOUR IN THE KIT, AND IT SHOULD BE CHANGED EVERY 5,000 TO 6,000 MILES. THE PROCHARGER CAN NOW BE MATED WITH THE BRACKET. SOCKET HEAD CAP SCREWS SECURE IT.

(MIKE)>> SOME OF THESE CARS HAVE SHAKER HOODS THAT ARE FUNCTIONAL. HOW DOES THE PROCHARGER INTERFERE WITH THAT?

(WALT)>> WELL YOU'RE RIGHT MIKE, THE FIVESEVEN RT CHALLENGERS AS WELL AS THE SIXFOUR SCAT PACK CARS, THE SHAKER, THAT'S A REALLY COOL PIECE, REALLY COOL FUNCTIONAL SETUP. THAT'S KIND OF THE BEAUTY OF OUR SUPERCHARGER LOCATION AND AIR FILTER SETUP IS THAT YOU CAN USE THAT SHAKER WITH NO OTHER MODIFICATIONS.

(MIKE)>> THAT'S PRETTY COOL. NOW NO OTHER COMPANIES REALLY DO THAT DO THEY?

(WALT)>> THAT'S CORRECT, WE'RE THE ONLY ONES.

(MIKE)>> PRETTY IMPRESSIVE! HERE WE GO WITH THE INTERCOOLER.

(PAT)>> WHEN YOU MAKE BOOST YOU CREATE HEAT. PROCHARGER MAKES ALL OF THEIR INTERCOOLERS IN HOUSE RIGHT HERE IN THE USA. IT ENSURES GREAT QUALITY CONTROL AND CONSISTENCY WITH HOW EFFICIENT THE COOLERS ARE. THIS IS THE HIGH OUTPUT COOLER, WHICH KEEPS THE TEMPS WITHIN 30 DEGREES OF AMBIENT DURING WIDE OPEN PULLS AT THE SEVEN POUNDS OF BOOST THIS JEEP WILL PRODUCE.

(PAT)>> WE ARE MOVING RIGHT ALONG ON THE PROCHARGER INSTALL ON THIS BEAUTIFUL 2017 JEEP GRAND CHEROKEE SRT EIGHT. PROCHARGER'S MANUAL GIVES A GREAT ILLUSTRATION OF HOW THE ENTIRE SYSTEM LOOKS INSTALLED. SO IT MAKES IT EASY TO GET EVERYTHING WHERE IT NEEDS TO BE.

(MIKE)>> WE'LL START BY GETTING THE CHARGE PIPES PLUMBED FROM THE SUPERCHARGER TO THE INTERCOOLER. THE FIRST COUPLE OF SECTIONS WE PREASSEMBLED. THE TOP CONNECTS TO THE SUPERCHARGER'S OUTLET. NEXT TO GO ON IS THE PRO FLOW BYPASS ASSEMBLY. NOW THIS IS MADE OF BILLET ALUMINUM AND IS DESIGNED FOR SUPER HIGH FLOW AND QUIET OPERATION FOR STREET DRIVEN VEHICLES. NOW PROCHARGER MAKES THIS IN HOUSE. THEY HAVE SIX DIFFERENT VALVES AVAILABLE FOR VARYING POWER AND BOOST LEVELS AS WELL AS SOUND PREFERENCE. NOW WE CAN MAKE THE CONNECTION TO THE INTERCOOLER. THE PIPES ARE DESIGNED TO PROPERLY CLEAR ALL THE FACTORY COMPONENTS TO AVOID ANY VIBRATIONS, WHICH CAUSE ANNOYING RATTLES. FROM THE PASSENGER SIDE INTERCOOLER WE HAVE ANOTHER SECTION OF PIPE TO PASS THROUGH THE CORE SUPPORT AREA. THEN THIS LARGE SECTION RUNS ACROSS THE TOP OF THE RADIATOR AND MEETS THE THROTTLE BODY. WITH THIS CONNECTION TIGHT THE ROUTING FROM THE OUTLET OF THE SUPERCHARGER TO THE INTAKE IS COMPLETE. THE INTAKE AIR TEMP SENSOR HAS BEEN RELOCATED TO THE BOTTOM OF THIS TUBE. IT WAS IN THE FACTORY AIR BOX AND WAS CLOSER TO THE STOCK HARNESS. SO PROCHARGER INCLUDES THIS EXTENSION HARNESS TO MAKE THE CONNECTION. REPLACING THE FACTORY WINDSHIELD WASHER TANK IS THIS FABRICATED ONE FROM PROCHARGER. NOW IT HOUSES THE FACTORY PUMPS AS WELL AS THE FACTORY LEVEL SENDER. IT ATTACHES TO THE VEHICLE WITH SUPPLIED HARDWARE ON THE SIDE OF THE RADIATOR SUPPORT.

(PAT)>> THE SAME GOES FOR THE COOLANT RESERVOIR, WHICH WAS ALSO FABRICATED IN HOUSE FROM PROCHARGER JUST LIKE THE WINDSHIELD WASHER TANK, AND IT GOES BEHIND THE PASSENGER SIDE HEADLIGHT.

(MIKE)>> THIS SUPPLIED VACUUM MANIFOLD SPLICES INTO THE BRAKE BOOSTER LINE. NOW IT'S HERE TO SUPPLY A VACUUM SIGNAL TO THE SURGE VALVE. THIS ONE HERE WILL BE USED ON THE DYNO. A THREESIXTEENTHS LINE MAKES THE CONNECTION TO THE VALVE.

(PAT)>> NOW THE FUEL SUPPLY LINE IS DISCONNECTED. FOUR BOLTS ARE REMOVED TO FREE UP THE RAIL. THEN ALL THE INJECTOR CONNECTORS ARE DISCONNECT AND THE WHOLE SHABANG LIFTS OFF. THIS IS SO WE CAN SWAP OUT THE FACTORY INJECTORS FOR THESE 52 POUNDS PER HOUR ONES SUPPLIED WITH THE SYSTEM. IT ALL GOES BACK ON THE SAME WAY IT WAS REMOVED.

(MIKE)>> THE FACTORY MAF SENSOR IS A ONE BAR, WHICH IS EQUIVALENT TO ONE ATMOSPHERE. SO IT READS FROM FULL MANIFOLD VACUUM TO NO VACUUM, WHICH HAPPENS AT WIDE OPEN THROTTLE. NOW THE SUPPLIED MAF SENSOR FROM PROCHARGER IS A TWO BAR, WHICH IS EQUIVALENT TO TWO ATMOSPHERES. NOW THIS WILL READ FROM FULL MANIFOLD VACUUM ALL THE WAY UP TO 14.7 PSI OF POSITIVE PRESSURE IN THE INTAKE TRACK, WHICH IS NEEDED TO SEE THE BOOST FROM THE PROCHARGER. THE FINAL HARD PART TO GO ON FROM PROCHARGER IS THE INLET TUBE AND CONICAL AIR FILTER. NOW THE RADIATOR IS TOPPED OFF WITH COOLANT, AND THE TUNE IS FLASHED INTO THE ECM USING A DIABLO HAND HELD PROGRAMMER. THE PROCHARGER TUNE IS LOADED INTO IT. THE INSTALL IS DONE AND WE'RE ALMOST READY TO HEAD OVER TO THE CHASSIS DYNO. BECAUSE OF THESE SIMILAR HEMI ENGINE PLATFORMS BETWEEN THIS JEEP, DODGE CHALLENGERS AND CHARGERS, RAM TRUCKS, AND CHRYSLER 300-C'S, THE INSTALL TIME IS ABOUT THE SAME FOR ALL OF THEM, RIGHT AT EIGHT TO 10 HOURS.

(PAT)>> IF YOU HAVE MECHANICAL SKILLS AND CAN FOLLOW SIMPLE INSTRUCTIONS YOU CAN DEFINITELY INSTALL THIS KIT. NOW BECAUSE THE WAY OF THE JEEP'S DRIVE SYSTEM WORKS WE ARE GONNA ACTUALLY DISCONNECT THE FRONT DRIVESHAFT TO MAKE OUR PULLS. THAT WAY WE DON'T RUN THE RISK OF DAMAGING ANY OF THE JEEP'S DRIVELINE, AND YOU'RE NOT GONNA WANNA MISS THAT. SO STAY WITH US.

(MIKE)>> WE'RE BACK, THE JEEP'S ON THE DYNO, AND YOU'VE GOT TO LOVE THAT PROCHARGER SOUND. NOW WE'RE JOINED BY ERIC RADZINS, PROCHARGER'S TUNING GURU.

(ERIC)>> WELL THE NICE THING ABOUT ON THESE LOADED DYNOS, YOU KNOW, THAT WE CAN GET A GOOD TUNE BECAUSE YOU'VE GOT THE GOOD SPARK QUALITY. THAT WAY, IT'S JUST LIKE OUT DRIVING ON THE STREET.

(MIKE)>> HERE WE GO! [ engine revving ]

(PAT)>> HERE WE GO, 570 AND 502 POUND FEET OF TORQUE ON THE FIRST YANK. THAT'S THE FIRST HIT.

(MIKE)>> THAT IS AWESOME!

(PAT)>> 570, 502. THAT WAS THE MOST UNEVENTFUL, UNDRAMATIC, QUIET, COOL SOUNDING 570 HORSE I'VE EVER HEARD.

(ERIC)>> JUST SMOOTH!

(MIKE)>> HOW BIG ON ENGINE YOU THINK THAT IS, CRANK HORSEPOWER?

(PAT)>> THAT'S OVER 700 AT THE CRANK ISN'T IT?

(ERIC)>> OH YEAH, IT HAS TO BE CAUSE THESE HAVE LIKE A 20 PERCENT DRIVETRAIN LOSS ACTUALLY.

(MIKE)>> IT'S GOING THROUGH A LOT. SEVEN POUNDS ALL THE WAY THROUGH THE PULL?

(ERIC)>> OH YEAH! [ engine revving ]

(PAT)>> THERE'S A LITTLE BIT FOR HEATING UP THE DRIVELINE, 582 BUT IT DROPPED A TAD BIT OF TORQUE, 499.68.

(MIKE)>> THAT'S WORTH GIVING IT UP.

(PAT)>> WE'RE DONE!

(ERIC)>> IT'S AWESOME, 582 TO THE TIRE.

(PAT)>> AND BASICALLY A LUXURY SUV. SO THAT'S IMPRESSIVE, I DON'T CARE WHO YOU ARE.

(ERIC)>> COME HERE, CHECK THIS OUT.

(MIKE)>> HOLY COW!

(PAT)>> 582.

(ERIC)>> THAT'S A HUGE GAIN FROM WHERE IT STARTS.

(PAT)>> AND TORQUE DROPS OFF A NEGLIGIBLE AMOUNT.

(ERIC)>> AND THAT COULD BE HOW HE ROLLED INTO THE THROTTLE.

(PAT)>> JUST A LITTLE BIT OF THAT, BUT DUDE, GOOD JOB.

(MIKE)>> WOW, THAT'S IMPRESSIVE! AWESOME, THAT GRAPH LOOKS REALLY NICE. WINNER, WINNER, CHICKEN DINNER!

THERE'S ONE LAST TEST TO PERFORM. WE DID THE STOCK ZERO TO 60 FOR A REASON. FIRST TIME WAS A FOUR POINT EIGHT. WATCH WHAT HAPPENS NOW!

HOW ABOUT A VERY IMPRESSIVE THREE POINT NINE SECOND ZERO TO 60? THAT'S A DIFFERENCE YOU CAN FEEL.

(PAT)>> TODAY WE ARE GOING TO GO OVER A HOTLY CONTESTED SUBJECT. THERE SEEMS TO BE A GREAT DEBATE. SO WE'RE GONNA EXPLORE A FEW FACTS ABOUT IT, AND I'M TALKING ABOUT FOOT POUNDS VERSUS POUND FEET. IT'S INTERESTING THERE'S EVEN A REAL ARGUMENT ABOUT THE CORRECT WAY TO EXPRESS THIS VALUE, ESPECIALLY THE WAY THAT WE USE IT. NOW I'M TALKING ABOUT TORQUE. NOW WE USE TORQUE A FEW DIFFERENT WAYS IN THE INDUSTRY, BUT THE MOST COMMON WAYS ARE WHEN WE USE TORQUE SPECS WHEN WE'RE TIGHTENING FASTENERS OR MEASURING THE TORQUE OUTPUT OF A RUNNING ENGINE. TORQUE IS THE MEASURED AMOUNT OF ROTATIONAL FORCE EXERTED ON A GIVEN LENGTH BAR FROM A CENTRAL POINT. WHATEVER THE LENGTH OF THE BAR, MULTIPLY WHATEVER THE AMOUNT OF WEIGHT IS ON THE END OF THAT BAR IS EXPRESSED AS TORQUE, AND IT DOESN'T MATTER IF THE BAR IS ONE FOOT LONG WITH 100 POUNDS ON THE END, OR 100 FOOT LONG WITH ONE POUND ON THE END, THE AMOUNT OF TORQUE IS THE SAME. HERE'S WHERE IT GETS INTERESTING. TORQUE WRENCHES IN AMERICA ARE STAMPED WITH A VALUE OF FOOT POUNDS, AND IT'S BEEN TOLD TO ME MORE TIMES THAN I CAN REMEMBER THAT THAT'S THE ONLY CORRECT WAY TO EXPRESS THAT VALUE. WELL THAT'S NOT THE CASE. SAE INTERNATIONAL'S TECHNICAL STANDARDS BOARD STANDARD EXPRESSION FOR THE UNIT OF MEASUREMENT FOR TORQUE, WHICH INCLUDES MOMENT OF FORCE, TORQUE BENDING, GENERAL ENGINE TORQUE, AND FASTENER MOMENT IS POUND FORCE FOOT. IF IT'S EXPRESSED IN SI UNITS, WHICH IS THE INTERNATIONAL STANDARD FOR METRIC, IT IS IN NEWTON METERS. NO ARGUMENT THERE. A WATER BRAKE DYNO MEASURES ENGINE TORQUE THROUGH A FORCE TRANSDUCER THAT CALCULATES A TORQUE VALUE. THE WATER BRAKE ROTATES AND PULLS ON THE TRANSDUCER WHEN LOAD IS APPLIED TO THE RUNNING ENGINE TO CONTROL ITS ACCELERATION RATE. IT'S THE SAME PREMISE, ROTATIONAL TORQUE. FOOT POUNDS OR POUND FEET, THE MATH IS THE SAME. IT'S LIKE SAYING TWO TIMES FIVE ISN'T 10 BUT FIVE TIMES TWO IS. IF YOU LOOK THROUGH THE CHEVROLET PERFORMANCE CATALOG AT HOW THEY LIST THEIR POWER NUMBERS ON CRATE ENGINES, THEY EXPRESS THEIR TORQUE VALUES AS POUND FEET. I'M JUST GONNA GO AHEAD AND LEAVE THAT THERE. IT REALLY DOESN'T MATTER TO ME PERSONALLY HOW IT'S EXPRESSED BECAUSE ACCORDING TO PHYSICS WE ARE TALKING ABOUT THE SAME THING WHEN WE'RE DISCUSSING ENGINE STUFF. NOW IF WERE DISCUSSING ENERGY, SAY KINETIC ENERGY, THAT IS EXPRESSED IN FOOT POUNDS, AND THE EQUATION IS MASS TIMES THE SQUARE OF ITS SPEED, BUT AS SOON AS YOU SAY THE WORD TORQUE WE'RE TALKING POUND FEET. TRADITION KEEPS FOOT POUNDS ALIVE AMONG GEARHEADS, AND AS LONG AS YOU ARE TORQUEING FASTENERS TO THE CORRECT SPECS AND BUILDING PERFORMANCE ENGINE TO KEEP THIS INDUSTRY MOVING FORWARD, WE'RE COOL WITH THAT.
