Ever since the creation of the internal combustion engine, engineers, racers, and race car designers have been looking for methods to boost its power. And, although building a bigger engine is a possible solution, it adds to the weight, cost, and maintenance – ultimately outweighing the benefits. That’s why boosting a normal-sized engine is a far more viable option.

One way to add power to the engine is to force more air through the combustion chamber. Extra air opens up more space for fuel, and more fuel ultimately creates a bigger explosion and increased horsepower. Using a supercharger is a great way to engineer this kind of forced air induction.

Superchargers have been used extensively for racing and production cars, but the technological complexity and cost typically limit its use to high-performance ones. Below we’ll look at how superchargers work and, by extension, how they can take your race car to its next level of performance.

Supercharger Basics

Once the air is drawn into an engine and sucked into the combustion chamber, it needs to be combined with fuel to create a charge – known as combustion. The more fuel you use, the more powerful an explosion you can achieve. However, you cannot simply pump more fuel into the engine because you need to balance the oxygen and fuel ratio. This is where the supercharger comes in.

Superchargers compress air without forming a vacuum, pushing more air into the engine. With methods like blower porting, you can even smooth out the supercharger’s internals to have less friction – making the air move with a better velocity. Ultimately, with more air in the engine, you can add more fuel and increase the engine power. 

The supercharger is powered with a belt or a chain drive that connects to the engine’s crankshaft. Most are driven by an accessory belt wrapped around a pulley that is connected to a drive gear. Making the drive gear bigger than the compressor gear causes the compressor to spin much faster, thus increasing horsepower by an average of 46 percent

Types Of Superchargers

There are two main types of superchargers that differ based on the method of gas transfer: positive displacement and dynamic compressors. Positive displacement superchargers achieve an almost constant pressure level increase regardless of the engine speed. Dynamic compressors, on the other hand, cannot deliver pressure at low speeds; instead, the speed pressure is increased rapidly after a certain threshold

UNLEASHING POWER AND PASSION: The Frank Tiegs Collection Roars into Barrett-Jackson’s 2024 Scottsdale Auction
2024 SCOTTSDALE AUCTION – 1969 CHEVROLET CAMARO YENKO COPO – NO RESERVE

Enthusiasts and collectors alike are in for an unforgettable showcase of automotive history with the Frank Tiegs Collection at Barrett-Jackson’s 2024 Scottsdale Auction, set to unfold January 20-28 at WestWorld. Frank Tiegs may not be a name that you are familiar with, but the world will know his collection when the auction concludes in January. This extraordinary collection features 28 muscle cars hailing from the late ’60s and early ’70s, each representing a chapter in the rich tapestry of American muscle. From the legendary Camaros to the rare Thunderbolt and the Hollywood-starred Oldsmobile, every vehicle in this showcase narrates a distinctive tale of power, performance and unbridled passion. Each will be auctioned with No Reserve, providing a unique opportunity to own a slice of the muscle-car legacy.

2024 SCOTTSDALE AUCTION – 1970 CHEVROLET CHEVELLE SS LS6 – NO RESERVE

One standout in the Frank Tiegs Collection is the Daytona Yellow 1969 Chevrolet Yenko COPO Camaro. Don Yenko himself sold this one, and it’s the only survivor, according to COPO Connection. The lineup also includes a black 1969 Chevrolet Camaro Z/28 RS and a silver one, adding more muscle to the mix. This 1969 Chevrolet Camaro ZL1 finished in silver is packing the original COPO ZL1 aluminum-block 427ci engine. This ride, #9 out of the 69 produced, went through a thorough restoration that used plenty of new-old-stock parts and a GM factory-assembled body shell to correct the body mods from its drag-racing days.

Completing the Chevrolet lineup in the collection, is a 1970 Chevrolet Chevelle SS LS6. It packs an LS6 454ci engine mated to an M22 4-speed manual Rock Crusher transmission. Holding on to its originality, it sports a CRV-code 3.31 posi-traction rear axle assembly. Also making its mark is a 1969 Chevrolet COPO Chevelle and a 1970 Chevrolet El Camino SS, one of the 4,475 LS6 cars built in 1970. These Chevrolets add a diverse touch to the already impressive collection.

2024 SCOTTSDALE AUCTION – 1970 PONTIAC GTO JUDGE RAM AIR III – NO RESERVE

Adding more color to the offering is the 1970 Pontiac GTO Judge Ram Air III, famously dubbed the “Psychedelic Judge.” Painted in Mint Turquoise, this GTO boasts a distinctive exterior adorned with factory Judge decals in blue, orange and pink, paired with a red bucket-seat interior. What makes this ride truly unique is its deviation from the standard color combo for a factory WT1 Judge option, a move not typically permitted but somehow realized by GM of Canada. Classified as one of the 75 GTO Judges finished in Mint Turquoise in 1970, this particular model stands out as a one-of-one “error,” as Mint Turquoise GTOs were intended to have black or Sandalwood interiors. Under the hood, the Psychedelic Judge is powered by a documented Judge 400ci Ram Air III engine, factory-rated at 366 horsepower and 445 ft/lbs of torque. It’s mated to a TH400 3-speed automatic transmission with a 3.55:1 posi-traction differential.

The collection also includes other Pontiac GTOs, such as a 1964 Pontiac GTO featuring a 389ci engine with a rating of 360 horsepower and finished in its original Silver Mist Gray color. Additionally, there’s another 1970 Pontiac GTO Judge Ram Air III in its original Starlight Black over a red interior, complete with full PHS paperwork and its Pontiac Division Window Sticker.

2024 SCOTTSDALE AUCTION – 1969 FORD MUSTANG BOSS 429 – NO RESERVE

The Blue Oval brand is well-represented in the Frank Tiegs Collection with a lineup of impressive Mustangs. Leading the pack is a 1969 Ford Mustang Boss 429 boasting a matching-numbers engine and rear end, with the added distinction of its VIN ending in 429. Another standout is a Grabber Green 1970 Ford Mustang Boss 429, preserving its original interior and factory options as detailed in the Marti Report and still rocking its matching-numbers engine along with original body panels and Ford factory parts.

Another Ford offering in the collection is a 1971 Mustang Boss 351, one of 1,806 Bosses built in 1971. Painted in the unique Bright Blue Metallic shade, this Boss 351 is one of seven featuring Magnum 500 chrome wheels, with five equipped with power steering, and only four produced with consoles and AM radios – making this Mustang one of the select three with this combination. Additional Mustangs in the collection include a meticulously restored, matching-numbers 1970 Ford Mustang Boss 302 and a 1969 Ford Mustang 428 SCJ R-Code equipped with the R-code 428ci Super Cobra Jet engine, 4-speed transmission and Drag Pak, and featuring a W-code axle.

Ex-Hans-Otto Butenuth BMW RS 500 at the Bonhams February sale
The Bonhams February sale is about to wrap up, so we’re taking a break from our regular scheduled programming to pick our favorite motorcycles from the auction. From an Ariel Square Four and a 1989 Kawasaki ZX-10, to Hans-Otto Butenuth’s BMW 500 Rennsport [above], here are seven classic motorcycles that we’d love to park in the Bike EXIF garage.

1907 Quadrant at the Bonhams February auction
1907 Quadrant In the early 1880s, two blokes by the names of Walter and William Lloyd patented a pedal tricycle steering mechanism, which they (very confusingly) called the ‘Quadrant.’ Anyway, Quadrant went on to make bicycles, tricycles, and motorcycles, and, by 1901, had emerged as one of Britain’s earliest motorcycle manufacturers.

This 453 cc Quadrant was originally built in Coventry and was meticulously restored by a previous owner. It showcases its history through hand-written notes, technical drawings, old registrations, marque-related literature, and an SMCC Pioneer Certificate.
