Show Winning 930 Turbo Has To Be One Of The Best

Show Winning 930 Turbo Has To Be One Of The Best This 911 Turbo has had the iconic slant-nose conversion along with an impeccable service record Everyone and their mate knows the story of the 911, and with good reason. A funky engineering experiment that despite all logic and reasoning has somehow stood the test of time with the same recipe, and continues to flourish today as one of the best sports cars money can buy. The 930, however, has to be the 911 poster car of all the generations. As one of the first cars to use turbocharging technology in a road car it officially established the ‘Widow Maker’ nickname that has stuck with it since.

If you were born in the 1970s, you likely observed the roadside world through the windows of a station wagon. Before minivans and SUVs, the people mover of choice was a rolling bench-seat bungalow with more square inches of glass around the occupants than cubic inches under the hood. These suburban family appliances were long, low, and boring.

But the wagon's utility can't be overlooked. The generous interior proportions and versatile seating configurations make them great for hauling lots of humans and gear. Since many rear-wheel-drive wagon platforms are shared with some of our favorite muscle cars, wagons are low-hanging fruit for hot rodding.

Enthusiasts run the most successful firms in the automotive aftermarket industry, and Holley Performance Products is no exception. To demonstrate the possibilities of the company's wares, Holley chooses project vehicles that not only scratch its hot rodding itch but serve as rolling testing laboratories for product concepts and promotion.

When Holley's chief gearhead, Tom Tomlinson (OK, his official title is president and CEO), came across a 43,000-mile 1974 Chevelle wagon, he couldn't pass it up. "I love wagons and frequently search for them. This car from Colorado came up. It was super-clean with low miles and had been decorated with some very hippy-style decals."

To day the Malibu is its own standalone model, and is a very different proposition to its ancestors.

Where some overlooked the portly fuel-crisis snoozer, squinting at the online auction photos, Tomlinson saw potential. Interest in GM's Gen III (LS) engines was catching fire, and Holley fueled the craze with swap-minded products to lower LS engine-swap barriers. The company needed a utilitarian, versatile testbed for products, and the A-body's quarry-sized engine compartment could accommodate virtually any engine combination. The Chevelle would make a great product-development workhorse.

The original concept for the wagon was "low-buck longroof." Planned as a budget-minded spit-shine with a mild drivetrain, the third-generation A-body needed a few subtle nips and tucks to give it a more muscular presence. Holley pulled the body off the frame and chucked the wheezy drivetrain. The frame and lowered suspension were powdercoated, and a subtle brown and cream paint job was applied to the body. The bumpers were shortened to suck them tighter to the fenders, with the front piece gaining a lower opening.

This week on PowerNation Courtney welcomes Holley president Tom Tomlinson and their retro looking '74 Chevelle wagon called "Low Buck Long Roof". Plus, Tom will give us a preview of this year' s Holley LS Fest scheduled for September 5th-7th at Beech Bend Raceway in Bowling Green, Kentucky.

Other than fresh carpet, the interior remains the same as when it lumbered off the assembly line. The straightforward theme continued under the hood, where a boneyard 6.0L LQ9 yanked from a wrecked truck replaced the Chevelle's smog-strangled small-block.

Holley topped the engine with its newly developed dual-quad carburetor setup and a set of big-block-inspired coil covers to motivate the wagon in groovy fashion. A set of Hooker cast-iron manifolds for modern LS engines kept the exhaust system '70s simple. While the electronics were separated from the hydrocarbons, Holley's Dominator ECU was used to run the ignition and transmission control for the 4L60E transmission.

The wagon was completed for the 2011 HOT ROD Power Tour, where it ran respectable 14-second quarter-mile times and sipped less than a gallon of gas every 20 miles.

As turbocharging started to trickle down to street-driven LS swaps, however, Holley's offerings for the hair-dryer faction grew from EFI systems to hard parts, including the company's turbo exhaust manifolds.

1959 Ford Ranch Wagon Reminds Us Why Wagons Are Cool

1959 Ford Ranch Wagon Reminds Us Why Wagons Are Cool With just one owner from new and 12,000 miles on the clock, this Ford is perfect for a collector. Combining tradition with progress is a difficult balancing act, with brand-loyal followers expecting more of the same, while the marque needs to promote innovation to compete with rivals. This was Ford’s situation in the 1950s with wood-bodied station wagons. The Ford Ranch became the blue oval’s first all-steel wagon. This 1959 Ford Ranch Wagon is the model’s second incarnation and initially aimed to inject a bit of style into this practical segment.

Holley products for GM's popular LS engine are dominating the LS scene as well. Holley ' s products also include performance fuel pumps, intake manifolds & engine dress–up products for street performance, race and marine applications.

Holley's engineering manager, Tim Grillot, filled us in on the details: "We launched our new Hooker turbo manifolds and wanted a test and marketing vehicle. We already had the wagon with the LS, and we thought it would be cool to breathe some new life into the wagon, as it had been in the same basic configuration for a few years. We wanted to showcase how easy our LS turbo manifolds make it for a consumer to add a turbo to their LS vehicle. Our goal with the manifolds was to offer an elegant, easy solution to turbocharging. Historically, fabricating the turbo headers is the most challenging part to a turbo system. We tackled that challenge with this very affordable and easy solution. These manifolds, when combined with our crossover tube, are a direct, bolt-on fit for most popular chassis."

Grillot's recollection of workplace water-cooler discussion led to a bench-racing showdown: "Tom [Tomlinson] challenged me to make the wagon run high-11s at full weight with the stock 6.0 truck engine that was in the car." Grillot responded as only a logical drag racer could; he scoffed and quickly stepped one lead foot confidently over Tomlinson's proverbial line in the sand: "Elevens? We'll run 10s with it."

While Grillot's ego confidently sauntered away to his office, a ticker tape of calculations trailed from the water cooler back to his desk. Reeling in the mental adding-machine tape revealed a balance of red ink. Stock 6.0L engine, 10:1 compression, 4,600 pounds—the horsepower side of the equation easily had four digits. Squeezing that kind of power out of a junkyard 6.0L engine—more than once—was a tall order. The odds of Grillot returning from the dragstrip with a 10-second slip or a box of parts seemed about even.

Bluster aside, Grillot wasn't completely out of his element. He had built two 4.6L Ford-powered turbo cars: a stick-shift 1965 Mustang that ran 10.80s on 17-inch street tires, and his 1978 Fairmont that ran 8.60 with a TH400 trans. Clearly, Grillot knew the "soft speed" potential of turbocharging.

Even though they planned to use the existing junkyard 6.0L engine, Holley knew the stock camshaft and valvesprings wouldn't keep the necessary boost from lifting the valves. A Brian Tooley Racing Turbo Stage II cam and PAC valvesprings replaced the stock components. The car's existing dual-quad setup was replaced with a single-plane EFI manifold and 95mm throttle-body.

Holley hung a 76mm Bullseye turbocharger off the company's aforementioned turbo manifold system and dumped the spent exhaust out the front right corner. A 50mm Turbosmart wastegate keeps boost under control, and an eBay-sourced air-to-air intercooler chills the intake charge. All the intake and exhaust plumbing was fabricated in-house in Holley's R&D facility.

A brushless Holley VR1 fuel pump feeds a steady supply of fuel to the Holley EFI injectors, rails, and fuel pressure regulator, and a Hughes-built 4L80E trans replaced the previous 4L60 unit. Grillot admits, "The torque converter is a little tight for an optimized drag vehicle, but this helps with street manners."

A 9-inch Ford axle with 3.70:1 gears rounds out the package. Holley uses two sets of wheels; on the street, the wagon rides on Circle Racing billet-aluminum 18-inch wheels covered in 245/45 and 295/45 Nitto NT555 tires front and rear, respectively. The steelie lookalikes are swapped out for track duty with a set of Weld RT-S beadlock wheels measuring 15x10 inches and holding 275/60-15 Mickey Thompson drag radials in the rear. The front rolls on Weld 17x4.5-inch Aluma Star 2.0 wheels and M/T Sportsman S/R 28 x 6 tires.

500+ HP Wagon: 1966 Dodge Coronet Deluxe Station Wagon

500+ HP Wagon: 1966 Dodge Coronet Deluxe Station Wagon It’s not every day you come across a station wagon that’s “ready to be taken to any drag strip.” In my opinion, wagons are one of the most practical vehicle configurations possible, and honestly, I really enjoy the styling of most wagons. It’s a shame that in today’s market, crossover SUVs have mostly replaced wagons, and while that’s another tangent for another day, you’d be hard pressed to transform a crossover into something as radical as this 1966 Dodge Coronet Deluxe Station Wagon.

The Chevrolet Chevelle Laguna is a mid-sized automobile produced by Chevrolet for the 1973 through 1976 model years. Part of the GM A-Body platform, the 1973 Laguna series included coupes, sedans and station wagons . It was the top-line Chevelle series that year positioned above the Malibu.

The '70 Chevelle SS Wagon was released in 2009 and was designed by Phil Riehlman. In reality, the Chevrolet Chevelle Wagon was not sold with the Super Sport package, but some hot rodders have added the bigger engine and SS badges to Chevelle wagons themselves.

When making the required power on a stock engine with 10:1 compression, careful tuning is critical. Holley's Matt Lunsford programmed the Dominator EFI system and squeezed out 905 rwhp on Holley's in-house Dynojet Dynamometer with the turbo shoving 19.5 psi down the stock motor's throat. Peak power was at 5,800 rpm, and a stump-yanking 862 lb-ft of torque peaked at 5,300 rpm.

Big numbers aside, Grillot speaks glowingly of the Chevelle's streetabilty: "The car feels exactly how it looks on the street: super comfortable, stylish, and plush. It is truly a treat to drive. The car has A/C, power steering, and stock brakes, so it really drives like a stock '70s cruiser. The engine is very mild, and coupled with the tunability of the Holley Dominator EFI system—that manages the engine, transmission, and all of the boost control—everything is very smooth and easy to drive."

But enough about street manners—did it run the number? At Holley's 2017 LS Fest in Bowling Green, Kentucky, it was time for Grillot to put up—or shut up. We were in attendance, and Grillot quipped: "Get your camera ready. I'm either going to run 10s in this thing or blow it up trying."

After strapping on his helmet and pulling the column shifter down into Drive, Grillot headed to the burnout box. "There is no transbrake, so it is a little hard to build boost on the starting line. As soon as it rolls out 30 to 60 feet, the boost comes in hard and fast and it quickly starts making lots of steam! Before you know it, you are sitting in what feels like grandma's station wagon, getting slammed in the back and quickly approaching speeds that seem unreasonable for the stock bench seat!"

How fast is unreasonable? How about a 10.89 at 130 mph? The sub-11-second pass gained Grillot essential bragging rights—and a friendly reminder from the track that cars shouldn't run 10s with a stock interior.

Besides proving out the company's electronic fuel injection and exhaust components, what else did Holley learn? Grillot says, "Turbos are an easy way to make lots of power!"

Holley doesn't plan any major changes to the car in the near future. "We're just going to drive it and have fun with it," Grillot muses. "The car will be taken on Power Tour and other shows. We'll continue to use it to showcase and develop new products. Just like any hot rodding project, it is a never-ending evolution."

Even though Grillot wheeled the car to the magic number, he's quick to credit Holley engineering lab technicians Lucas Embry and Logan Duvall, who did all of the wrenching and assembly of the current setup on the wagon, including the camshaft, turbo, fuel system, transmission swap, and all associated wiring.

By launching this 2-ton barge into the 10s, this project raises more than eyebrows and expectations. It raises questions about the perceived limits of hot rodding—and the bidding prices of mid-1970s A-body wagons.

Reader’s Ride: 1974 Trans Am.
Having never forgotten about that Firebird, I had a dream of finding a 1970s Firebird Trans Am and restoring it. I found it after two years of searching. A body-off restoration had been started in 1997 by the previous owner. All of the bodywork had been completed, including being painted in its original color, Cameo White. A new Baer four-wheel disc-brake system, a full Hotchkis suspension system, a rebuilt steering system, and a new TA rearend had all been installed on the car. Some of the interior had been refurbished, and the 455 motor and transmission had been installed.
