Amazing Photos From IROC Racing!

“Spanning the globe to bring you a constant variety of sports; the thrill of victory and the agony of defeat. The human drama of athletic competition … This is ABC’s Wide World of Sports.”  Legendary ABC Sports broadcaster Jim McKay spoke those words every Saturday afternoon for 37 years, from 1961-1998, when ESPN became the premier sports broadcasting channel.  Those words of Jim McKay were heard in millions of American homes.

ABC Sports was particularly fond of showing motorsports.  Every Saturday afternoon, millions of American children (and adults!) were treated to 90 minutes of non-mainstream motorsports like NASCAR, NHRA, demolition derbies, surfing, and even the Joie Chitwood Thrill Show.  While I’ve never seen the Joie Chitwood Thrill Show, it must have been good enough to be shown on one of the very few TV channels on the air at the time.  This is when IROC racing entered the motorsports scene in the early 1970’s.  It ran for a good 15 years or so, reaching it’s peak around 1980.  There was no other place where you could watch NASCAR legends like Richard Petty and Bobby Allison duke it out with F1 legends like Emerson Fittipaldi and Denis Hulme.  Throw in Mario Andretti, and you were bound to sit back and watch one hell of a ride.

The late Chris Economaki was always commentating on some form of motorsports, and his talent showed during the pre-race commentary of IROC V.  IROC V was the 5th IROC season, and the year was 1978.

While most younger Camaro enthusiasts will think that IROC was simply an option package developed for the Camaro starting in 1985, there’s more to the story.  The story behind IROC goes all the way back to 1973 with Roger Penske, Les Richter, and Mike Phelps (no relation to the swimmer of the same name!) all had the amazing idea to put 12 of the world’s greatest race car drivers in identical cars to compete on road courses and NASCAR superspeedways alike in a four-race series.  Richter was cautious enough to say that the IROC series might not determine who the best driver was, “but we sure go a long way towards that goal.”

The first IROC season was the 1974 season, and it kicked off on October 27, 1973.  It consisted of 4 events with all racing done in identically-prepared Porsche 911 RSR’s.  For the 1975 season, Chevrolet came on board, and the Chevrolet Camaro was the car of choice.

Here are some pictures that have only recently been released to the public.  Enjoy.

The Crash That Changed NASCAR Forever

At Talladega International Superspeedway in 1973, Bobby Isaac heard voices telling him to pull over.  It wasn’t his crew chief, it wasn’t his spotter, but he said that it was a supernatural voice.  Nothing at all was wrong with his car.  But, he got spooked by the voices and quit racing on the spot.  He pulled into pit row, turned the car off, got out, and never set foot in a race car again.

Odd things happen at Talladega all the time.  Fans and drivers joke around casually about the “Talladega Jinx.”  The Jinx itself is standard issue – every track has it in some form or another.  People say that Talladega was once a Native American burial ground and the spirits haunt the track to this day.  As silly as those stories may seem, Talladega has been a haven for mishaps since Day 1.  Larry Smith lost his life there because of a minor-yet-deadly accident.  Davey Allison lost his life there in a helicopter crash.  Side-view mirrors have killed drivers there.  There have been so many infield accidents that I can’t even count how many there are.

But, it was Bobby Allison’s near-fatal crash there in a Grand National-series Buick LeSabre in 1987 that changed NASCAR superspeedway racing forever.  There were no murderous mirrors or supernatural voices.  Instead, a blown tire at 200+ mph sent Allison’s number 22 Buick LeSabre stock car into the air.

The result was sickening.  His car was moving with such momentum that it literally vaporized the catch fence and sprayed the crowd with debris.  Thankfully, two well-placed and tightly-wound cables kept most of the car from landing in the crowd.  The only serious injury was a spectator who lost an eye – sad but not deadly.  Bobby Allison continued to race after the crash at Talladega until the next year, when a career-ending crash at Pocono Speedway in 1988 caused him to hang his helmet up for good.  However, Jinx conspiracy theorists will happily point out to you that his family didn’t escape the Talladega Jinx until 1993, when Bobby’s eldest son, Davey Allison, lost his life in a helicopter crash there, just 11 months after Bobby’s youngest son, Clifford, perished in a massive crash at Michigan International Superspeedway.

In Bobby Allison’s crash, speed was what nearly killed him.  Just a day prior to the race, Junior Johnson, a notoriously reckless driver back in his day, voiced his concerns to NASCAR officials.  They should have listened to him.  Junior Johnson is still one of the most respected figures in NASCAR public circles.  NASCAR executives put on the headphones to ignore the thundering engine of Junior Johnson.  Why?  Because Bill Elliott had just put his car in first place at a screaming 212.8 mph.  Big numbers look good in newspapers.  To put that into perspective, the fastest speed at the Indy 500 the next week was 216.6 mph.  Indy cars are light, small, and maneuverable.  Stock cars are like automotive battleships.  When Bobby Allison hit the fence, NASCAR officials could have faced an accident that could have played out like the 1955 24 Hours of Le Mans disaster.  Crazy speeds or not, something had to be done quickly.

To reduce top speeds, the stopgap measure was to implement smaller carburetors.  Teams hated it, not only speed-wise, but because it also hindered the car’s performance in many other ways.  It took a full season to reach an agreement, but when the green flag dropped at the 1988 Daytona 500, each car in the field had a restrictor plate bolted to the intake manifold.  The restrictor plate is still mandatory at superspeedways like Daytona and Talladega, as it greatly restricts the airflow going into the engine.  The result is a significant reduction in top speed.  A restrictor plate is simply a piece of metal with four holes in the center for the air to go through.

Restrictor plates didn’t cure the jinx.  Crowd injuries at Talladega are still far too common.  In that case, why install a restrictor plate at all?  Until his death, NASCAR CEO Bill France, Jr. always said that the restrictor plates were bolted on to improve the show.  To this day, it’s hard to find something more spectacular than NASCAR.  The restrictor plate greatly reduces the airflow going into the engine, so, if there is an accident, the car will not be traveling over 200 mph.  Superspeedways are the only NASCAR tracks that allow the cars to get up to speeds like that.  Plus, there’s no denying the spectator appeal of “The Big One,” the gigantic crashes at restrictor plate events that fans have come to expect and see as for-granted.

Is the Talladega Jinx real?  Um, no.  There’s no supernatural entity plotting over what will happen next at Talladega.  But, the Jinx is well-planted into the minds of drivers and fans.  Either way, restrictor plates are still for this world for a while – superstition or not.

 

 

The Greatest American Turbocharged Cars

Many people think that turbochargers belong in heavily modified import cars.  Well, that’s partially true.  Europe has turned out some impressive turbocharged cars, as well as the US of A.  Here are America’s greatest turbocharged cars.

  • Ford Mustang SVO:  The 2015 Ford Mustang has a 2.3-liter turbocharged 4-cylinder engine, just like the SVO Mustangs of the 1980’s.  The first turbocharged Ford Mustang showed up in 1979 with a 135-horsepower, turbocharged, 2.3-liter four-cylinder engine.  It was an alternative to the downsized 4.2-liter V8 found in the Mustang GT.  But, it wasn’t until Ford’s Special Vehicle Operations (SVO, now known as Special Vehicle Tuning or SVT) got their hands on one that it became anything noteworthy.  It came with a factory-installed Hurst short-throw shifter, revolutionary Koni adjustable shocks, ABS disc brakes at all four corners, a limited-slip differential, and a screaming, turbocharged 205 horsepower.  Drivers even had the cool option of flicking a dash-mounted switch that allowed the car to run on lower-grade fuel for a certain amount of time.  When it ended it’s production run in the late 1980’s, it was something to be feared.  It looked especially menacing in grey.
  • 1965 Chevrolet Corvair:  Believe it or not, the Corvair actually had a go-fast option.  It had two, in fact.  One was the Crown Corvair, which used a mid-mounted 283-cubic-inch Corvette V8, and the other was a turbocharger bolted onto the engine.  From the factory.  It made 150 horsepower initially, but by the time the Corvair died, it made 180 horsepower.  Unlike many other turbocharged cars, the turbocharged Corvair did not use a wastegate, the internal exhaust flap that opens at higher engine speeds to prevent over-spinning the turbine.  Instead, Chevy engineers simply built enough backpressure into the exhaust system to prevent overboost and serious engine damage.  Very few Corvairs with the turbocharged engine were ever made.
  • Oldsmobile F85 Jetfire:  Oldsmobile was one of the early adopters of turbocharging technology.  It released the powerful F85 Jetfire in April of 1962, and the car was something of a small success.  It took the fabled 3.5-liter high-compression “Rocket” V8, cranked up the boost, and let it rev.  It made a screaming 215 horsepower, and it was easily quicker than many naturally aspirated cars of 1962.  Plus, owners got an ashtray-sized boost gauge in front of the shifter.  The engine had problems with detonation, which is the process where the hot air-fuel mixture under pressure spontaneously ignites before the spark plug has a chance to ignite it.  So, the Turbo-Rocket engine was fed a mixture of methanol alcohol and water (the same stuff fed to dragsters).  This allowed the mixture to not ignite as quickly and get a higher octane level.  Today, water/alcohol injection is commonplace in high-performance tuner car applications, but isn’t it cool that F85 Jetfire owners had to periodically fill their “Turbo Rocket Fluid” reservoir?
  • Buick GNX:  If there’s a poster-child for American turbocharged cars, the Buick GNX wins, hands-down.  The all-black, tire-smoking, Ferrari Testarossa-beating, quarter-mile waltzing Buick GNX was and still is a force of nature.  Buick initially started turbocharging it’s anemic 3.8-liter V6 in 1978 for the Regal and the LeSabre, introducing the fast Regal Grand National line in 1982.  It culminated with 1987 with the GNX.  Buick purposefully underrated the crank horsepower at 276 horsepower, but dyno tests showed that the car made at least 315 horsepower at the wheels.  This means that the car made somewhere close to 360-370 horsepower at the crank.  It even beat the twin-turbo Callaway Corvette that I featured on my blog a couple of months ago in the quarter mile.  The GNX would go through the quarter mile in the low 13-second range at around 125-130 mph.  Just 547 GNX’s were built in 1987, each specially massaged by AMC/McLaren.  Today, the turbo Buick’s are something of a legend, and many go for upwards of $30,000.  The car was so successful on the street the Buick entered a naturally-aspirated V8 version of the car in NASCAR’s Grand National series (now known as the Nationwide Series), where it was extremely competitive.
  • 1989 Pontiac 20th Anniversary Turbo Trans Am:  The all-white Pontiac Trans Am picked to be the pace car for the 73rd annual Indy 500 was completely different than the first turbocharged Trans Am, which was all mustache and no Burt.  This 1989 force-fed pony car was something completely different.  I liken it as the Pontiac storm trooper to the Buick GNX Darth Vader.  Pontiac subcontracted an engineering firm to swap Buick GNX engines (made by Buick for Pontiac) into the Trans Am.  But, the story doesn’t (and shouldn’t) end there.  Anniversary-edition Trans Am’s got better-flowing heads than the GNX, stainless-steel headers, GNX-sized Eaton intercoolers, a cross-drilled Comp Cams crankshaft, and their own engine tuning higher up in the powerband.  The net result was a car that officially produced 250 horsepower at the crank, but made closer to 320 horsepower at the crank.  This marked a return to the horsepower-underrating days of the muscle car, started by, you guessed it, Pontiac.  It was the fastest pace car ever in the history of the Indy 500, which is impressive, given the fact that many fast cars have been chosen since then.
  • Ford Thunderbird Turbo Coupe:  The Beach Boys made the T-Bird famous with the line, “fun, fun, fun, until her daddy takes it away.”  The T-Bird was fun until Daddy (the EPA) introduced emissions regulations that took the fun out of the T-Bird.  By 1982, the T-Bird was a horrible, anemic shoebox of a car.  Happily, 1983 saw the rising of the phoenix.  It’s beak-like hood had twin nostrils that meant that there was a turbocharged engine underneath that pointy hood.  Other than the amazingly 1980’s-FILA edition, the T-Bird Turbo Coupe was at it’s peak in 1987 and 1988.  That was when stick-shifted version of the Fox-bodied T-Bird came equipped with a whistling 190 horsepower, four-wheel ABS disc brakes, and a limited-slip differential.  Those nostrils on the hood, by the way, are functional, as they feed air directly to the top-mounted intercooler.
  • Shelby GLHS:  It’s hard to find a car that has a shape that’s more square than the Dodge Omni.  The blocky Omni had all of the sporting pretensions of a worn-out water shoe.  Then, you hand the Omni over to Carroll Shelby.  Early Omni GLH (unofficially Goes Like Hell) cars weren’t turbocharged, but by the mid-1980’s, America was becoming obsessed with the turbocharger.  So, by the mid-1980’s, the Omni GLH had enough punch to beat any VW GTI of the era.  For the 1986 model year only, 500 cars were further tweaked by Shelby to become the Omni GLHS (Goes Like Hell S’More), which was a 175-horsepower breadbox with more boost, better suspension, and factory options like a roll cage and heavy-duty oil cooler borrowed from the Ram 250 with the Cummins Diesel.  Quite possibly the best part of the GLHS:  The uprated top speed of the GLHS was too much for the regular 85 mph speedometer of the Omni, so Shelby simply added a sticker to the bottom of the gauge with increments up to 135 mph.
  • Shelby CSX-VNT:  Another Shelby creation was the CSX-VNT, which was based off of the homely Plymouth Sundance and Dodge Shadow.  Initially, the CSX-VNT packed 175 horsepower, and like the earlier GLHS, went like a bat out of hell.  Shelby built a small run of 1,001 cars for the Thrifty rental car company with slightly less power.  In the final year of CSX-VNT production, 1989, the CSX-VNT included some new, unique technology previously only seen on race cars – variable turbine geometry.  Computer-controlled vanes moved to direct the hot exhaust gas stream to improve spool-up time.  While it’s power rating remained the same at 175 horsepower, it had dramatically better response time in the low end, virtually eliminating turbo lag.  The next time this technology would show up in the U.S. market would be in 2011, with the 997-generation Porsche 911 Turbo.  That was more than 15 years later.
  • GMC Syclone:  In 1990, Gale Banks Engineering cracked the 200-mph mark at the Bonneville Salt Flats in a compact GMC pickup truck with no turbocharger or supercharger.  In 1991, the streetable version of that high-powered pickup showed up on dealer lots.  It’s 4.3-liter Vortec V6 engine was turbocharged with the help of Gale Banks himself.  It came standard with ABS and AWD, neither of which were options on the S15 Sonoma.  You couldn’t haul much with the Syclone, unfortunately, as it was only rated to haul 500 pounds.  Too bad, but you could still fill the bed with the egos of every single Porsche, Ferrari, Lamborghini, and Maserati driver on the road.  This all-black, one-year-only mini-truck was the fastest-accelerating production vehicle in America for a few years, easily getting off of the line, thanks to the torque-rich engine and AWD.  It got to 60 mph somewhere in the low 4-second range.
  • GMC Typhoon:  A spin-off of the one-year-only Syclone, the Jimmy-bodied Typhoon was officially rated at 280 horsepower, though dyno tests showed that it made at least that at the wheels, meaning that it made somewhere around 320 horsepower at the crank.  It could easily beat a Ferrari 348 off of the line and up to about 70 mph, when the 348 really got into the powerband.  Just under 5,000 Typhoons were made between 1992-1993, and unlike the black-only Syclone, could be bought in a variety of colors.  In fact, Clint Eastwood used to drive a Forest Green Typhoon around in his Dirty Harry days, where he would pull up to a stoplight and ask punks if they felt lucky. Most thought they were going to beat some middle-aged guy in his SUV with their Mustang or import car.
  • Dodge Neon SRT4:  In 2003, Chrysler/Dodge’s Street Racing Technology (SRT) team got hold of the friendly-faced Neon subcompact car, and built what is still the car to beat for bang-for-your-buck performance.  A frog-eyed four-door sedan with a functional front-mounted intercooler peeking out of the grille, the tiny Neon made mincemeat out of everything from a Porsche Boxster to a Nissan 350Z.  Dodge claimed 230 horsepower, though dyno testing showed that the car made at least that much, if not more at the wheels.  This means that the engine was making close to 280 horsepower at the crank.  Something else that is cool about the Neon SRT4 is the fact that it doesn’t have a muffler on it.  This allows it to have vastly better turbo flow.  Resonators keep the volume semi-sane, but the Neon really makes a lot of noise when you give it some go-juice.
  • Chevrolet SS Turbocharged:  Initially available only as a supercharged coupe, the Cobalt SS was always OK in performance testing, but it wasn’t going to set any records.  Starting in 2009, the Cobalt SS came as either a sedan or coupe with a turbocharger bolted onto a small four-cylinder engine.  It made 260 horsepower.  Should you want a cool sleeper, if you aren’t afraid of the ignition recall, you can get a Cobalt SS, take the badges off, swap the big chrome rims for something more discreet (like the regular Cobalt rims), and you’d have the makings of a good sleeper.  It had a no-lift-shift system – just keep your right foot floored so that you don’t loose boost – and you’ll see the quarter mile fly by in under 13 seconds, and will keep up with a Porsche 911 on a road course.  Take it out to the twisties out on the road, and you’ll be able to keep up with a motorcycle, thanks to the tiny size of the Cobalt.

Ford Wins 12 Hours of Sebring for the First Time Since 1969!

The last time Ford won the 12 Hours of Sebring was back in 1969.  That was when a Ford GT40 MkI beat out a Ferrari 312P.  That was at the tail end of Henry Ford II and Enzo Ferrari’s decade-long motor sports rivalry.

Now, 45 long years later, Chip Ganassi Racing’s Ford Daytona Prototype brought the glory back to Dearborn after 12 chaotic and dramatic hours.

The skilled drivers, Marino Franchitti, Scott Pruett, and Memo Rojas, managed to get the Ford Daytona Prototype across the finish line a mere 5 seconds ahead of Ryan Danziel and the Extreme Speed Motorsports HPD ARX-03B.  They managed to do this after a late restart bunched the field up.

The win makes Chip Ganassi the only team owner ever to have race titles from the Daytona 500, Indianapolis 500, Rolex 24 Hours at Daytona, and the 12 Hours of Sebring.

As for the GT classes, cars from Stuttgart took the win.  Andy Lally, John Potter, and Marco Seefried won GT Daytona in the No. 911 car.  Amazing pit stops helped Jörg Bergmeister, Patrick Long, and Michael Christensen drive the CORE Autosports Porsche 911 RSR to victory in the GTLM class.

With the Prototype Challenge class, former NASCAR Nationwide Series champion Colin Braun helped put the CORE-ORECA Chevrolet FLM09 best reigning class champion Bruno Junquiera.

With the highly anticipated Chevrolet Corvette C7.R, fuel pump issues and 2 spins dropped the leading Vette to 6th, which disappointed driver Oliver Gavin.  Ben Keating and the SRT Viper GT-D retired within the first hour after a truly spectacular fire.

The revolutionary Nissan DeltaWing led its class for several laps, but retired after Lap 104, thanks to a collision on that lap, in addition to a botched pit stop and multiple mechanical issues.
