Katech Motorsports
Katech Program Management


Katech works with management of an existing or new race series to develop vehicle packages, series spec engines, conformance testing, engine control software, team training, track support, and overall process improvements.

On demand, Katech can then follow through with program management for the series, ensuring that inventory, testing, technicians, and other resources are in place to keep the series running smoothly.


Katech draws on its 40 years of racing to develop engines that meet exacting performance requirements and regulations. We maintain a full-service CNC laboratory and six test laboratories to modify existing engines to series spec, and to validate performance.

GM built its legendary Corvette Racing Program on the insight and technical innovation of Katech engine developers and builders. That same expertise continues to be sought today by race series throughout the world.

Engine Build


If you need an engine built, Katech has the master engine builders to meet your needs and surpass your expectations. Katech engines are assembled using a rigorous 48-step process that is documented and kept on file at Katech for the life of the engine.

In addition, the Katech WHISTLER is a proprietary electronic device that instantly determines the compression ratio of virtually any engine. Whistler is used by NASCAR and SCCA.


Katech’s reputation and record in motorsports – winning races and championships worldwide, dominating at leading venues – is legendary, and at the heart of every product and service we provide.

In 2019, Katech engines brought drivers and teams to the podium time and again in two venues: the Trans Am Series, and the IMSA Prototype Challenge Series presented by Mazda.

In the TA1 class, Katech powered Breathless Racing to the 2019 Team Championship, and driver Ernie Francis, Jr. to the Driver’s Championship. Francis began racing with Katech engines in the TA4 class in 2014, and became the youngest driver ever to win TA championship in 2016. Last year in TA2, teams running Katech engines grabbed two wins and saw the podium ten times.

Katech will continue to be active in Trans Am in 2020, so watch for posts on our results! This year’s Trans Am schedule can be found here.

For the IMSA PC series, Katech provided engine track support for all LMP3 cars racing in the circuit; all LMP3 engine rebuilds for the entire North American market; and
technical, electronic, and engine support for all LMP3 cars present in North America. To check-out the 2020 series schedule, click here.



Katech firmly established its racing roots when it was selected to develop the C5-R race engine for General Motors. The engine was originally a 6.0L engine, but it soon became apparent that a larger engine was needed to compete with the Dodge Viper’s V10. Katech responded with a 7.0L engine, and it became the standard for the rest of the C5-R’s life. It dominated the GTS/GT1 class until it was replaced by the C6.R.



Corvette Racing debuted an all-new car, the C6.R, in 2005. Katech was once again chosen to be the engine supplier and developed the LS7.R 7.0L engine. As a result, Corvette Racing dominated the competition for years to come, with 54 one-two finishes; six class victories in 24 Hour of Le Mans; seven class wins in the 12 Hours of Sebring; seven class titles in 1,000 mile/10 Hour Petit Le Mans; and an overall victory in 24 Hours of Daytona.



Katech launched its racing legacy in ASA, with the first six-cylinder engine ever to run in the series. During its ten-year run, Katech gathered dozens of victories, pole positions, and podium finishes, plus four Driver’s and Team Championships, while also supplying engines to four Rookie of the Year drivers.

When ASA turned to spec engines, Katech provided their development and supported the series with track support.



Typically, Bonneville Salt Flats records are isolated to straight-away speed. And, normally, Katech delivers high-performance engines providing thousands of durable miles – not just a few miles of top-end speed. But when GM decided they wanted to put a V6 into an S15 to gain bragging rights in the “200 mph club”, they came to Katech. We delivered.



Katech was asked to develop the engine for the Ronn Bailey Motorsports team competing in the Dakar rally. The legendary 10,000km off-road race starts in Lisbon, Portugal and travels through Spain, Morocco, Western Sahara, Mauritania, and Mali before ending in Dakar, Senegal. Its brutal conditions make finishing the race an honor. The engine delivered through seven stages before gearbox problems forced them to retire.



When GM decided to compete in the Grand-Am GT category with the GTO.R, Katech engines went into Pratt & Miller prepared cars. The list of achievements was impressive: eight first place finishes; six second place finishes; six third place finished; 19 consecutive podium finishes overall; a Grand-Am GT Manufacturer’s Championship; a Grand-Am GT Driver’s Championship; and a Grand-Am GT Team Championship.



When Pontiac opted to campaign two G6 GXP.Rs in Grand-Am GT – with the Banner Racing Team and Pratt & Miller cars – Katech supplied the new LS2 engines. The first year on the track, the team achieved runner-up finishes in both team and driver standings. The second season they slammed it, winning four races and capturing all three championships – for the team, the drivers, and for manufacturer Pontiac.



IMSA has been home to numerous series over the years, with Katech on the platform time again, building the company’s legacy of “winning and success” from start to finish:

• 3 Manufacturer Championships – Kelly American Series;
• 2 Driver’s Championships – Kelly American Series;
• 2 Manufacturer Championships – RS International Sedan;
• 1 Manufacturer Championship – GTU;
• 1 Driver’s Championship – GTU;
• 2 Manufacturer Championships – GTS-1;
• 2 Driver’s Championships – GTS-1;
• 1 Manufacturer Championship – WSC; and
• 1 Driver’s Championship – WSC.



Katech was in a relationship with AJ Foyt Enterprises, running in the IRL, when asked by GM to develop the Aurora V8 engine for the series. GM then began selling the engine in “kit form” to other IRL teams. In essence, Katech began competing against itself! No problem. Despite providing power to the entire series, Katech captured the IRL Driver and Team Championship.



Only six years after the company’s founding, Katech was chosen to be the exclusive engine supplier for the International Race Of Champions series. In 1984 IROC switched from the second generation Chevrolet Camaro to the all-new third generation Camaro powered by a Katech 350ci small block V8. This wider body design gave rise to the production Camaro IROC-Z that was built from 1985-1990.

In 64 races, from 1984 to 1989, there was only one engine failure – when a driver over-revved the engine when his vehicle became stuck in mud off-track. This program was also instrumental in the restrictor testing which was put in place in NASCAR.



Taking on NASCAR, Katech won three consecutive Busch Grand National Championships as well as capturing three Cleveite Engine Builder of the Year Awards. All these achievements were accomplished with multiple teams using a variety of drivers. Katech’s statistic for the five years in the series: three Championships, one runner-up, 18 victories, and 19 pole positions.



The Renault Le Car program choose Katech to rebuild an engine for a performance power vehicle. The engine was completely overhauled, and Renault used the powerplant to win two IMSA RS International Sedan – Manufacturer Championships over three years.



After missing action on the track for nearly 50 years, Cadillac entered two cars into the SCCA World Challenge Division, both running Katech engines. In their very first race, at Sebring, Cadillac captured the first and second pole positions. The team then went onto three victories. The second year proved more successful, with Cadillac winning four races and capturing both the Manufacturer’s and Driver’s Championships.

At the end of the run, Katech and Cadillac achieved two Manufacturer’s Championships, one Drivers Championship, and outstanding 38 podium finishes and an incredible 12 victories.



The engine featured in the Cadillac CTS-V.R race cars for this series was the GM 6.2L naturally aspirated V8 , which was adapted by Katech to conform to the World Challenge regulations. The engine helped establish Cadillac as a worthy competitor, and not just a luxury brand.



The Grand-Am revolutionized major league sports car road racing in North America. And Katech was at the heart of it. Katech developed the engine powering the Chevrolet Camaro GT.R running in the premier Rolex GT category – a 6.2L naturally aspirated V8 adapted from the GM 6.2L LS3.

There were 21 GT.R engines built, and Chevrolet teams stood on the podium 10 times, finishing in first and second place 5 times each.



Reiter Engineering built its reputation on taking supercars, like the Lamborghini, and turning them into race cars. When the 2010 Camaro was introduced, the masculine styling, retro look and aggressive body lines induced Reiter to venture outside its norm of building Lambos.

When deciding what engine should power the new Camaro GT3 race car, Reiter turned to Katech. The result: a 7.9 liter aluminum V8 making 650 HP and ground pounding torque.



Katech’s amazing Trans Am success speaks to shear dominance in performance engines: seven Team Championships, seven Driver’s Championships, and 46 victories. Katech had one car complete 517 laps of 517 lamps attempted!

Katech has developed and won with a carbureted V6, a fuel-injected V6, and a carbureted V8. Katech engines have won the unlimited TA class Team and Driver’s Championships the past three years, 2017-2019.



Katech built its reputation for endurance engines by never compromising – continually raising the bar on engine durability through advanced validation, failure analysis, and testing. This uncompromising mentality brought wins in some of the most challenging endurance races in the world:

• 24 Hours of Le Mans: 6 first place finishes; 5 second pace finishes;
• 24 Hours of Daytona: 2 first place finishes;
• 24 Hours of Spa: 2 first place finishes;
• 24 Hours of Zolder: 2 first place finishes;
• 12 Hours of Sebring: 6 first place finishes, 5 second pace finishes; and
• 10 Hours of Petit Le Mans: 7 first place finishes.



Team Solaris Motorsports came to Katech to build engines for the Chevy Luminas running this series that would provide tons of horsepower and a linear torque curve, with the goal of taking full advantage of the car’s power both on the straights and exiting the corners. Katech designed and built an LS3-based engine making more than 550 horsepower.
