“Opposites Attract” Something for everyone…..

(MIKE)>> WELCOME TO ENGINE POWER. TODAY WE'RE FINISHING UP THE FRS AND TAKING IT BACK TO THE NATIONAL CORVETTE MUSEUM ROAD COURSE. NOW THIS CAR HAS CHANGED IN A LOT OF WAYS. IT'S MAKING 97 MORE HORSEPOWER AT THE REAR TIRES, HAS A MASSIVE BAER BRAKE KIT ON IT, HOOKER EXHAUST, AND SEVERAL ADJUSTABLE SUSPENSION COMPONENTS FROM THE FT 86 SPEED FACTORY.

(PAT)>> NOW IT'S TIME TO GIVE IT THE FINAL TOUCHES FOR TRACK DAY STATUS, AND THAT WILL INCLUDE NEW WHEELS AND TIRES, SETTING UP THE COIL OVERS, AND GOING OVER ALL THE FASTENERS, FLUID LEVELS, AND SYSTEMS ON THE CAR.

(MIKE)>> SETTING UP THE COIL OVERS IS NOT A ONE SHOT ADJUSTMENT. THERE ARE SEVERAL FACTORS INVOLVED, LIKE THE SIZE OF THE TIRE, HOW MUCH CLEARANCE IT HAS IN THE WHEEL WELL, AND THE AMOUNT OF GROUND CLEARANCE THE CAR HAS. NOW THEY ALL PLAY A ROLE. NOW THE FIRST THING WE NEED TO DO WITH THIS STYLE OF COIL OVER IS SET THE SPRING'S PRELOAD. THEN WE'LL SET THE RIDE HEIGHT. NOW AS FAR AS REBOUND AND COMPRESSION GO, THOSE WILL BE SET OUT AT THE TRACK. LET'S GET STARTED. SETTING THE PRELOAD IS DONE BY ROTATING THE SPRING ADJUSTOR TO PUT MORE TENSION ON THE SPRING. IF THIS IS NOT DONE THE SPRINGS WILL MAKE UNWANTED NOISES LIKE POPPING WHEN TURNING THE WHEEL DUE TO BINDING OR SPRING ROTATION. SIMPLY TIGHTEN THE ADJUSTOR UNTIL THE SPRING HAS QUITE A BIT OF ROTATING TENSION BUT IS NOT UNABLE TO ROTATE. IF IT'S NOT ENOUGH PRELOAD YOU'LL STILL HAVE NOISE WHEN THE STEERING WHEEL IS TURNED. JUST ADD MORE TO GET RID OF IT.

(PAT)>> RIDE HEIGHT IS ADJUSTED BY ROTATING THE BOTTOM MOUNT UP OR DOWN ON THE SHOCK BODY. NOW THIS IS INDEPENDENT OF SPRING PRELOAD, AND DUE TO THE FACT THAT THESE ARE ALREADY INSTALLED ON THE VEHICLE, HERE'S A QUICK WAY TO MAKE THAT ADJUSTMENT. WITH THE SWAY BAR LINK DETACHED AND THE TWO SPINDLE BOLTS LOOSENED AND REMOVED, LET THE SPINDLE DROP DOWN. SIMPLY ROTATE THE LOWER MOUNT CLOCKWISE TO LOWER THE CAR. THESE SAME STEPS WILL BE DONE ON THE OPPOSITE SIDE. REMEMBER THIS IS JUST A ROUGH SETUP. WE TOOK A MEASUREMENT WITH THE FACTORY WHEELS AND TIRES AND HAVE A ROUGH IDEA OF WHERE WE NEED TO BE ON RIDE HEIGHT. THIS SIDE NEEDS TO BE LOWERED ABOUT THREE QUARTERS OF AN INCH.

(MIKE)>> THE REARS ARE DONE THE SAME WAY. WITH THE PRELOAD SET AND THE SWAY BAR END LINK AND COIL OVER DETACHED, THE BOTTOM BRACKET IS TURNED COUNTER CLOCKWISE TO RAISE THE REAR OF THE CAR, WHICH IS WHAT WE NEED TO DO.

(PAT)>> OUR SCION NEEDS A WHEEL THAT CAN HANDLE THE DEMANDS OF BOTH HEAVY TRACK DAYS AND EVERYDAY STREET DRIVING, AND THAT'S WHY WE CHOSE THE ENKEI WHEELS, AND FOR A FEW DIFFERENT REASONS. THIS IS THEIR "RAGIN'". NOW ASIDE FROM ITS OBVIOUS GOOD LOOKS THERE IS A TON OF ENGINEERING THAT GOES INTO THIS RACE INSPIRED WHEEL DESIGN. ENKEI USES MAT DURAFLOW FORMING TO MAKE A WHEEL THAT'S STRONG YET LIGHTWEIGHT, WHICH ENHANCES ITS STRAIGHT TO WEIGHT RATIO, AND THIS MANUFACTURING PROCESS ALLOWS THEM TO MAKE NEAR INFINITE STYLES AND SHAPES, AND THEIR SUPERIOR CRAFTSMANSHIP IS CLEARLY EVIDENT WHEN YOU HANDLE THEM, FINDING NO SHARP EDGES AND SEEING THEIR PREMIUM FINISH. NOW THESE ARE 18 BY NINE AND A HALVES, AND THEY'LL GO ON ALL FOUR CORNERS.

(MIKE)>> WRAPPED AROUND THOSE AWESOME WHEELS ARE MAXXIS VICTRA VR ONE ULTRA HIGH PERFORMANCE TIRES. NOW THESE ARE EXTREME SUMMER TIRES WITH A NEW COMPOUND THAT REACHES OPERATING TEMPERATURE QUICKLY AND PROVIDES EXCELLENT DRY TRACTION. NOW THEY HAVE A NEW PATTERN DESIGN THAT MAXIMIZES DRY PERFORMANCE AND MINIMIZES THOSE WHITE KNUCKLE MOMENTS IN WET WEATHER. NOW A NEW REENFORCED CASING AND SIDE WALL DESIGN PROVIDE A TELEPATHIC RESPONSE FOR THE ULTIMATE DRIVING EXPERIENCE. THE TREAD WEAR RATING IS 200. OUR GOAL IS TO HAVE AN AGGRESSIVE LOOK AND EXCELLENT HANDLING. 265/35 18'S WILL ACCOMPLISH THAT.

(PAT)>> THE RIDE HEIGHT HAS BEEN SET, AND WE DID HAVE TO MAKE A FEW MORE ADJUSTMENTS TO THE COIL OVERS ALL THE WAY AROUND TO GET IT RIGHT. NOW WE ARE GONNA WEIGH THE CAR TO SEE HOW IT SCALES OUT AS FAR AS FRONT TO BACK BIAS AND CROSS WEIGHT. WE'LL USE OUR INTERCOMP QUICK WEIGH SET THAT IS WIRELESS. THEY'RE PLACED UNDER EACH WHEEL ON THEIR ASSIGNED CORNER.

(MIKE)>> WE'RE INTERESTED IN A FEW THINGS. ONE IS THE TOTAL WEIGHT OF THE CAR, WHICH IS 2,792 POUNDS. FACTORY WEIGHT WAS 2,760. SO WE GAINED 32 POUNDS WITH THE BIGGER WHEELS AND TIRES, BRAKES, SUPERCHARGER, AND ALL THE SUSPENSION COMPONENTS. SECOND WE WANT TO SEE WHAT THE CROSS WEIGHT OF THE CAR IS PERCENTAGE WISE. FROM THE LEFT FRONT TO THE RIGHT REAR WE'RE SHOWING 49.14 PERCENT. FROM THE RIGHT FRONT TO THE LEFT REAR IT'S 50.86, SHOWING THAT THIS CAR IS REALLY, REALLY BALANCED. NOW THE LAST THING WE'RE GONNA LOOK AT IS THE ACTUAL LEFT TO RIGHT SIDE. 50 PERCENT ON THE MONEY ON THE SCALES THE FIRST TIME. IT DOESN'T GET MUCH BETTER THAN THAT. NOW PAT'S GONNA GET IN THE CAR SO WE CAN CHECK THE CROSS WEIGHT WITH A DRIVER IN IT LIKE IT WOULD BE OUT ON THE RACE TRACK. NOW THE CROSS WEIGHT FROM LEFT FRONT TO RIGHT REAR SHOWS 49.8 PERCENT, AND FROM THE RIGHT FRONT TO THE LEFT REAR IT SHOWS 50.20 PERCENT, STILL REALLY WELL BALANCED. THE LEFT SIDE WEIGHT IS 51.54 PERCENT WITH PAT SITTING IN THE DRIVER'S SEAT. WE'RE NOT GONNA MAKE ANY CHANGES NOW. MAYBE SOME SLIGHT ADJUSTMENTS OUT ON THE TRACK.

(MIKE)>> WELCOME TO NCM MOTORSPORTS PARK IN BOWLING GREEN, KENTUCKY. IT'S PAYOFF TIME FOR OUR SCION FRS. A CAR THAT'S COME A LONG WAY FROM STOCK TRIM. NOW EQUIPPED WITH A SUPERCHARGER, FULL SUSPENSION, BIG BRAKES, AND PERFORMANCE TIRES. HOW WILL IT PERFORM? LET'S FIND OUT! WHEN WE NEED TO HAUL OUR PROJECT CARS OR HEAD TO THE TRACK FOR A PAYOFF LIKE TODAY WE NEED A GOOD TRAILER TO GET THE JOB DONE. SO H&H TRAILER SUPPLIED THIS 30 FOOT BUMPER PULL THAT'S PACKED FULL OF FEATURES. CHECK SOME OF THEM OUT. IT'S A ROOMY 30 FOOT LONG CAR HAULER WITH AN EXTRA TALL CEILING AND RUBBERIZED BLACK COIN FLOORING. A 30 AMP ELECTRICAL PANEL WITH SIX BREAKERS, INTERIOR LIGHTS, AIR CONDITIONING, AND A 9,500 POUND WINCH. UNLIKE MANY COMPETITORS THIS TRAILER HAS FULLY BOXED FRAME RAILS. HERE'S A NEW TOY WE'RE GOING TO PLAY WITH TODAY. IT'S A CALLED A VBOX. ALL RIGHT SO THAT'S CAMERA ONE. GPS ANTENNA PLUGS IN. IT'S A VIDEO LOGGER AND PERFORMANCE METER ALL IN ONE. NCM HAS A 15 MILE AN HOUR SPEED LIMIT IN THE PITS. NO BIG DEAL. WHAT IS A BIG DEAL, IT'S ONLY FOUR DEGREES WARMER THAN THAT AT 19 DEGREES. NOW SOME OF YOU ARE THINKING, WHY ARE YOU EVEN THERE. THE TIRES AREN'T GONNA WORK. WELL THE HIGH TODAY IS 48, AND THE TRACK TEMPERATURE USUALLY INCREASE 10 TO 15 DEGREES WITH THE SUN OUT LIKE THIS OVER AMBIENT AIR TEMPERATURE. SO WE SHOULD BE OKAY.

WE'RE NOT ALONE TODAY. MAKING LAPS WITH US IS HOLLEY PERFORMANCE'S R&D FRS THAT'S RUNNING THE SAME SUPERCHARGER AND EXHAUST. WE DO HAVE A SLIGHT ADVANTAGE WITH BIGGER BRAKES AND MORE EXTENSIVE SUSPENSION MODS. THERE'S NOT A GEARHEAD IN THIS WORLD THAT WOULDN'T COME OUT AND HAVE A BLAST DRIVING THIS CAR, AND REALLY RESPECT IT ONCE HE GOT OUT OF THE DRIVER'S SEAT. THIS IS THE PERFECT EXAMPLE OF WHY SO MANY AFTERMARKET COMPANIES ARE MAKING AWESOME PARTS FOR THIS CAR. IT IS A PERFORMANCE MACHINE. WELL THE SUN DIDN'T STAY OUT AND THE TRACK TEMPERATURES NEVER CAME UP. THANKS WEATHER MAN! NOW ONE THING WE ARE IMPRESSED ABOUT ARE THE MAXXIS VICTRA TIRES WE'VE BEEN RUNNING TODAY. THESE THINGS ARE REALLY IMPRESSIVE EVEN IN THIS COLD WEATHER. SO WE'RE GONNA GIVE IT A SHOT AND MOVE UP TO THEIR RACE TIRE. NOW THIS IS A DOT APPROVED "R" COMPOUND THAT IS NAME THE VICTRA RC ONE. IT HAS A 100 TREAD RATING, AND IT WAS DESIGNED BY RACERS FOR RACERS. NOW YOU CAN RUN THIS TIRE AS AN AUTO CROSSER OR AS A WEEKEND WARRIOR. NOW WE'RE GONNA GO AHEAD AND BOLT THEM ON, TAKE THEM OUT ON THE TRACK, AND GET THEM SCRUBBED DOWN. AFTER A FEW SCRUB IN LAPS THESE RC ONES ARE COMING AROUND, EVEN IN THE COLD, AND THE VBOX PROVES IT. JUST ABOVE THE SPEEDO IS A "G" METER. WE'RE PUSHING THE BALL RIGHT TO THE LIMIT. NOW IF YOU'RE WATCHING THE MAP, YOU CAN SEE EXACTLY WHERE WE ARE ON THE TRACK. THE MORE I DRIVE HEAT BUILDS UP ON THE TIRES AND THE GRIP INCREASES AT A FAST RATE. IF YOU'RE NOT A FAN OF IMPORTS HOPEFULLY WE CHANGED YOUR VIEW. IT DEFINITELY CHANGED MINE.

(MIKE)>> WE'RE BACK AT THE POWERNATION HEADQUARTERS AFTER A VERY SUCCESSFUL DAY OUT AT THE TRACK WITH OUR FRS. NOW THIS IS AN AWESOME MACHINE AND TO REALLY APPRECIATE IT YOU'VE GOT TO GET OUT AND DRIVE ONE. NOW PAT AND I ARE BACK IN THE ENGINE POWER SHOP WHERE WE'LL CONTINUE WITH OUR '07 CSIX CORVETTE WE DUBBED "ATOMIC BLAST".

(PAT)>> LAST TIME YOU SAW IT WE TOOK CARE OF THE ENGINE WITH A TOP END KIT FROM TRICK FLOW, BOLTED ON AN MSD ATOMIC INTAKE MANIFOLD, AND 102 MILLIMETER THROTTLE BODY FROM NICK WILLIAMS. ON THE EXHAUST SIDE A SET OF HOOKER BLACKHEART SHORTY HEADERS WERE INSTALLED. THAT LEADS US TO PHASE TWO, WHICH WILL WRAP UP THE EXHAUST SYSTEM ALONG WITH NEW SUSPENSION, A BRAKE UPGRADE, PLUS ALL NEW WHEELS AND TIRES.

(MIKE)>> IN MY BOOK A MODIFIED CORVETTE HAS TO SOUND AGGRESSIVE. RECENTLY PAT AND I HEARD A CSIX CORVETTE WITH ONE OF HOOKER BLACKHEART'S AXLE BACK EXHAUST SYSTEMS, AND THAT TRIGGERED US TO PUT ONE ON THIS CAR. NOW IT'S A THREE INCH STAINLESS STEEL SYSTEM THAT USES A HIGH FLOW STRAIGHT THROUGH MUFFLER. NOW THIS WILL GIVE YOU AN AGGRESSIVE SOUND DURING ACCELERATION AND A NICE MELLOW TONE DURING IDLE. NOW IT HAS FOUR INCH DUAL WALLED STAINLESS STEEL TIPS, AND THIS BIG CAN HERE IS A HELMHOLTZ STYLE RESONATOR THAT HELPS CONTROL INTERIOR RESONANCE. THE EXISTING MUFFLERS ARE NOT FACTORY. WE'RE REMOVING THEM BECAUSE WE WANT A DIFFERENT SOUND. BASICALLY USER PREFERENCE. THE OVER AXLE PIPES GO ON FIRST, ONE FOR THE RIGHT SIDE, ONE FOR THE LEFT. NOW THE FACTORY HANGERS GO ON THE NEW MUFFLERS, AND THE ASSEMBLIES ARE INSTALLED ONE AT A TIME. THIS MUFFLER LOGO PLATE TIES THE TWO MUFFLERS TOGETHER AND ENSURES PROPER ALIGNMENT.

(PAT)>> NOW TIGHTEN ALL OF THE CLAMPS. WE GIVE THE BLACKHEART LINE OF EXHAUST AN APLUS FOR FITMENT, QUALITY, AND OF COURSE SOUND. NOW WE'RE GONNA SLOW DOWN A LITTLE BIT AND TALK ABOUT BRAKES. CORVETTES FROM THE FACTORY ARE ENGINEERED WITH AN EXCELLENT BRAKING SYSTEM FOR THEIR PERFORMANCE ENVELOPE, BUT WE'VE MADE SIGNIFICANT CHANGES TO THE ENGINE. SO THAT ENVELOPE IS GONNA NEED TO BE READDRESSED. EBC OFFERS BRAKE UPGRADE KITS LIKE THIS THAT RETAIN THE STOCK ROTOR DIAMETER AND CALIPER BUT WITH A SIGNIFICANT INCREASE IN BRAKE PERFORMANCE. THESE ARE THEIR BSD BLADE ROTORS, AND THEY'RE MANUFACTURED FROM A SPECIAL MATERIAL KNOWN AS "DISCALLOY". THE UNIQUE BLADE SLOT DESIGN HELPS REMOVE THE HOT GASES FROM THE BRAKING ZONE QUICKER AND MORE EFFICIENT AS COMPARED TO A UNIDIRECTIONAL SLOT. THIS HELPS KEEP THE PADS FLATTER AND THE BRAKES COOLER. THE BLUE STUFF NDX PADS ARE MADE FROM A HIGH FRICTION SPORT AND RACE MATERIAL THAT CAN BE USED FOR AGGRESSIVE STREET DRIVING AND TRACK USE. THEIR BIGGEST ADVANTAGE IS THEIR ABILITY TO BITE FROM COLD, A PROGRESSIVE BRAKE FEEL, AND THE ABILITY TO BRING THE CAR TO A COMPLETE STOP WITH EASE. EBC'S PRODUCTS ARE DIRECT REPLACEMENTS AND OFFERED IN SEVERAL ROTOR AND PAD COMBINATIONS, FROM DAILY DRIVING, TO OPEN TRACK, AND FULL RACE EVENTS.

(MIKE)>> THE SUSPENSION IS NEXT. THIS IS ALDAN AMERICAN'S COIL OVER KIT FOR CFIVE AND CSIX CORVETTE PLATFORMS. NOW ALL THE COMPONENTS, MATERIALS, AND TESTING ARE DONE RIGHT HERE IN THE USA. NOW THIS KIT IS DESIGNED TO GIVE A HUGE IMPROVEMENT IN HANDLING AND RIDE COMFORT. THEY'RE MACHINED FROM LIGHT WEIGHT AIRCRAFT GRADE ALUMINUM AND HAVE CNC LASER CUT AND TIG WELDED BRACKETS FOR STRENGTH. FOR FINE TUNE DAMPENING THESE FRONTS ARE SIX WAY ADJUSTABLE. THE REARS ARE 11 WAY ADJUSTABLE. ALDAN AMERICAN SPRINGS ARE COLD WOUND HIGH TENSILE STEEL FOR GREATER CONSISTENCY AND PERFORMANCE. THE KIT ALLOWS A HALF TO ONE AND A HALF INCH RIDE HEIGHT ADJUSTMENT. THE LAST SUSPENSION PARTS ARE STEINJAGER SWAY BARS. THE FRONT IS AN INCH AND A QUARTER, THIS REAR IS ONE INCH. NOW HEAVY DUTY NYLON RACE SPHERICAL ROD ENDS CONNECT THEM TO THE CONTROL ARM. YOU CAN PURCHASE THE COIL OVER KIT AND SWAY BARS FROM TPS MOTORSPORTS DOT COM. NOW WHEN WE COME BACK FROM THE BREAK ONE FINAL TOUCH AND TO THE DYNO WE GO. SEE YOU SOON.

(MIKE)>> WE'RE BACK AND THE FINAL TOUCH FOR THIS STAGE OF "ATOMIC BLAST" IS GOING ON. THESE ARE BBS RSGT TWO PIECE DYE FORGED ALUMINUM WHEELS. THEY'RE A LIGHTWEIGHT WHEEL AND RETAIN EXCELLENT STRENGTH DUE TO THE MANUFACTURING PROCESS. THE FASTENERS ARE TITANIUM. THE FRONT WHEELS ARE 18 BY NINES, THE REARS 19 BY 10.5. MICHELIN PILOT SUPER SPORTS MAKE THE CONNECTION TO THE ROAD. THEY'RE DESIGNED AND ENGINEERED WITH ENDURANCE RACING IN MIND. NOW YOU CAN EXPECT BETTER HANDLING, BETTER BRAKING, AND LONGER TREAD LIFE THAN ITS COMPETITORS. TWARON BELT TECHNOLOGY MAINTAINS HIGH SPEED STABILITY AND EVEN WEAR ACROSS THE TREAD. TUNER ALEX PIETZ JOINED US AGAIN, BUT IN A DIFFERENT WAY.

(PAT)>> ALEX THANKS FOR JOINING US FROM HOUSTON, FROM YOUR SHOP. SKYPE'S KIND OF A NEW THING FOR THE HP TUNERS BUT THEY HAVE A GREAT THING FOR REMOTE TUNING. COULD YOU TELL US A LITTLE BOUT HP'S REMOTE TUNING?

(ALEX)>> WELL BASICALLY PAT WHAT WE'RE DOING IS I'M LIVE REMOTE LOGGING IN TO WHATEVER COMPUTER THE INDIVIDUAL AT THE SHOP IS USING ON THE DYNO AND I'M ACTUALLY USING THEIR HP TUNER SOFTWARE ON THEIR COMPUTER, AND I'M TUNING IT AS IF I WERE THERE IN THE ROOM WITH THEM.

(PAT)>> HOW ARE YOU GONNA APPROACH PUTTING A BASELINE TUNE IN THIS THING?

(ALEX)>> WE'RE GOING TO ADJUST THE INJECTOR DATA, AND WE'RE GOING TO ADJUST THE IDLE TO ACCOUNT FOR THE CAM. SINCE YOU HAVE THE CAM PRESENT THE EFFICIENCY OF ENGINE IS GOING TO DROP SOME AT IDLE. SO WE'RE GOING TO HAVE TO TAKE SOME FUEL OUT ESSENTIALLY AT IDLE. JUST TO GET THINGS GOING INCREASE THE AIR FLOW AS WELL SO WE CAN GET IT ACTUALLY STARTED UP AND START GETTING SOME DATA TO MAKE MORE ADJUSTMENTS.

(MIKE)>> AND THAT COMES IN THE WAY OF A STEP TEST, FROM 1,500 TO 3,500 IN 500 RPM INCREMENTS.

(ALEX)>> THE DATA'S LOOKING REALLY GOOD FROM OUR STEP TEST. FUEL TRIMS ARE GOOD. I THINK WE'RE READY TO GO AND DO A 3,000 TO 5,000 RPM PULL JUST TO VERIFY THAT AIR/FUEL RATIO IS SAVED AND GOOD. THEN WE CAN GO ON TO OUR POWER PULL. [ engine revving ]

(PAT)>> IT'S ALMOST 12.7 THE WHOLE WAY.

(ALEX)>> AWESOME, THAT'S WHAT WE WANT TO SEE. I THINK WE'RE READY TO GO AHEAD AND PULL IT TO 6,500 AND START MAKING SOME POWER.

(MIKE)>> POWER PULLS ARE DONE IN FOURTH GEAR. THIS ONE FROM 3,000 TO 6,500 RPM.

(PAT)>> ALL RIGHT ALEX, FIRST HIT, 415 HORSEPOWER, 376 POUND FEET OF TORQUE. REALLY, REALLY FLAT FROM 12.7 TO 12.8.

(ALEX)>> AWESOME, THAT'S DEFINITELY A GOOD START IN THE RIGHT DIRECTION. I THINK WE SHOULD GO AHEAD, ADJUST THE SPARK ADVANCE, AND DO ANOTHER RUN, AND SEE WHERE WE GET.

(MIKE)>> WITH THE CHANGES MADE IN THE TUNE WE SHOULD SEE A JUMP IN POWER. I'LL MAKE THIS FINAL PULL TO 6,800.

(PAT)>> ALL RIGHT, YOU READY FOR THIS? THAT'S A TUNE UP RIGHT THERE. 440 HORSE, 390 POUND FEET OF TORQUE.

(ALEX)>> WOW THAT REALLY PICKED UP WELL.

(PAT)>> THAT'S WHAT HAPPENS WHEN YOU MAKE GOOD CHANGES AND IT COOLS DOWN A LITTLE BIT.

(MIKE)>> I COULD FEEL A DIFFERENCE IN HERE.

(PAT)>> IT SOUNDED BETTER. AIR/FUEL, NOW IT WAS A LITTLE ON THE LEANER SIDE, WHICH IS GOOD. IT STARTS OUT AT 12.8, 12.9 AND THEN IT CREEPS UP AROUND TO 13.1, 13.2. SO PRETTY SWEET!

(ALEX)>> SO I THINK WE'VE DEFINITELY MADE SOME GREAT HEADWAY. IT'S MAKING GOOD POWER FOR WHAT WE'VE GOT IN IT, AND I'M READY TO GO DRIVE THAT THING DOWN THE STREET.

(MIKE)>> THE VIEWERS WATCHING THE SHOW, IF THEY DON'T HAVE ACCESS TO A DYNO OR THEY LIVE IN A REMOTE AREA WHERE THERE'S NOT A DYNO, CAN THEY DO THIS BY DRIVING DOWN THE STREET WITH LIKE A HOT SPOT OFF OF THEIR CELL PHONE ON THE LAPTOP?

(ALEX)>> I'D LOG INTO THEIR COMPUTER AND THEY USE THEIR HOT SPOT ON THEIR PHONE, AND WE TUNE IT ON THE STREET.

(MIKE)>> VERY COOL MAN. WELL THANKS AGAIN FOR HELPING US OUT AND WE'LL SEE YOU SOON.

(PAT)>> THANKS MAN!

(ALEX)>> I LOOK FORWARD TO IT, THANK YOU GUYS.

(PAT)>> IT'S TIME FOR SOME MORE CAM SHAFT TECH. NOW YOU'VE SEEN US GO OVER DIFFERENT TYPES OF CAMS, LIKE FLAT TAPPET AND ROLLER, WHETHER THEY'RE HYDRAULIC OR SOLID. WELL TODAY WE'RE GONNA EXPAND ON THAT KNOWLEDGE AND GO OVER THE CAM CARD. WHAT'S THE CAM CARD? IT'S THE INFORMATION THAT COMES WITH EVERY CAM THAT YOU BUY THAT TELLS ITS SPECS FROM THE GRINDER. DEPENDING ON THE MANUFACTURER THE CARDS WILL LOOK DIFFERENT BUT THEY ALL CONVEY THE SAME INFORMATION. THE TERMINOLOGY USED IS INDUSTRY STANDARD IN REGARDS TO THE VALVE'S EVENTS. KEEP MIND THE CAM'S JOB IS TO ACCURATELY OPEN AND CLOSE THE INTAKE AND EXHAUST VALVES IN RELATIONSHIP TO THE CRANK SHAFT'S POSITION. FROM AN ENGINE BUILDER'S POINT OF VIEW THE FIRST NUMBERS WE LOOK AT IS THE DURATION AT 50 THOUSANDTHS LIFT. EVERY CAM CARD WILL HAVE THIS MEASUREMENT NO MATTER THE BRAND. THIS IS HOW WE COMPARE CAM SHAFTS TO ONE ANOTHER BECAUSE THIS IS AN INDUSTRY STANDARD MEASUREMENT. DURATION IS THE AMOUNT OF DEGREES THE VALVE IS OPEN, AND FOR COMPARISON IT'S MEASURED AT 50 THOUSANDTHS VALVE LIFT AS THE VALVE OPENS, AND AT 50 THOUSANDTHS VALVE LIFT BEFORE IT CLOSES. THIS CARD STATES THAT THOSE EVENTS OCCUR A HALF A DEGREE BEFORE TDC, AND 55.5 DEGREES AFTER BDC. HERE'S WHAT THAT LOOKS LIKE. THIS DRAWING REPRESENTS THE BALANCER AND ITS INCREMENTS, PLUS THE CRANK SHAFT'S ROTATION. SO ACCORDING TO OUR CAM CARD, AT 50 THOUSANDTHS LIFT IT IS A HALF A DEGREE AFTER TDC AND IT IS 55.5 DEGREES AFTER BDC ON THE CLOSING SIDE AT 50 THOUSANDTHS LIFT. SO THAT DOESN'T MEAN IT'S SEAT TO SEAT TIMING. THE VALVE ACTUALLY CRACKS OPEN A LITTLE BIT BEFORE THAT, AND WHEN IT CLOSES IT'S AFTER THIS MEASUREMENT HERE. ADVERTISED DURATION IS WHAT A LOT OF COMPANIES USE TO MAKE THEIR CAM SEEM BIGGER, BUT YOU CAN'T USE THEM FOR COMPARISON PURPOSES BECAUSE THEY DON'T USE THE SAME VALVE LIFT MEASUREMENTS FOR THE NUMBERS LIKE THE INDUSTRY STANDARD 50 THOUSANDTHS. ADVERTISED DURATION IS MOSTLY USED FOR MARKETING PURPOSES. NEXT UP IS LOBE LIFT, AND IT'S THE PHYSICAL AMOUNT OF LIFT THE LOBE HAS FROM ITS BASE CIRCLE TO ITS NOSE. THIS NUMBER IS COMBINED WITH A ROCKER ARM RATIO TO GIVE YOU THE GROSS VALVE LIFT. KEEP IN MIND THIS MEASUREMENT IS NOT FROM THE BOTTOM TO THE TOP OF A LOBE. IT IS THE TOP OF ITS BASE CIRCLE JUST TO THE NOSE, AND THIS IS WHAT WE USE TO CALCULATE BOTH GROSS AND NET VALVE LIFT. THE LOBE LIFT MULTIPLIED BY THE ROCKER RATIO EQUALS GROSS VALVE LIFT MINUS ANY LASH THAT YOU HAVE, AND THAT EQUALS NET VALVE LIFT. FOR EXAMPLE, OUR CAM CARD SAYS WE HAVE 368 THOUSANDTHS LIFT MULTIPLIED BY ONE POINT SEVEN, WHICH IS OUR ROCKER RATIO, AND THAT EQUALS 625 THOUSANDTHS GROSS VALVE LIFT. NOW THERE'S A LOT MORE TO CAM CARDS, BUT WE'LL GET TO THAT NEXT TIME.
