Mallett Supercharged 2015 700+HP Colorado featured on Chevrolet Performance The Block

The folks at Chevrolet Performance’s The Block came by the shop to do a photo shoot and story about our 2015 Chevrolet Colorado back in 2016. They enjoyed our take on the Colorado so much, they ran it again this year.

Read the full story below.

For our final story of 2018, we’re looking back to a local Chevrolet Colorado here in Charlotte, North Carolina. This is not just any Colorado, but an intense racer set up with nothing in mind but quick lap times. It’s a four-seater pickup the owner tells us will pass C7 Stingrays at your local road course. We’re of course talking about Chuck Mallett, of Mallett Performance Cars, and his supercharged V6 Colorado with over 700 horsepower.

Mallett swapped in a 3.6L V6 from a 2016 Cadillac ATS-V due to that engine already being built for boost since forced induction was his desired path to horsepower success. The engine features a forged crank, titanium connecting rods and forged pistons. Bolted to the top is a Mallett Colorado Intercooled Supercharger Manifold assembly complete with a Magnuson 1.9L supercharger, custom 64mm C&R intercooler, custom CNC-machined upper and lower 8-rib pulleys, front engine idler pulley, tensioner mounting plate, drill-less mounted aluminum intercooler tank and water pump and C&R heat exchanger. Mallett used a C7 LT1 throttle body to open up the intake side and crafted a custom air intake box. Spent gasses are expelled through a custom high-flow dual exhaust, and let us tell you, it’s a true high flow as we breathed in the sweet nectar that is 109 race fuel while moving the truck in the parking lot during the shoot.

Power is nothing without getting it to the ground. Behind the V6 is a modified stock transmission that turns a narrowed Moser nine-inch rear-end with WaveTrac and aluminum center section. The rear differential then spins beautiful Forgeline custom MS3C concave wheels – 19×9.5 front and 20×13 rear – wrapped in rear 315/35/20 BFGoodrich G-Force Rivals. And spin they do — even with all that traction. Feathering the throttle just maneuvering the vehicle in a parking lot induced rear shrieks of euphoria from the sticky rubber.

To keep contact with the road and increase lateral stability, a lot of custom work was performed by Mallett and the team to the chassis and suspension. First, ride height needed to be adjusted to lower the center of gravity while maintaining correct geometry. Custom drop spindles were fabricated with custom lower control arms up front. Custom Penske coilover shocks were also installed. Out back, the rear frame section was raised and narrowed and a custom three-link ladder system with center frame crossbar and driveline hoops were fabricated and welded in. A custom rear sway bar and adjustable panhard bar were installed to fine tune the truck’s balance on track. Mallett knew his horsepower goals, his truck’s goal weight, and worked backwards from there determining the optimal wheel/tire sizing. Knowing the size of said rear tires, Mallett took to tubbing the truck bed some four-and-a-half inches wider each side, which as you can see in the photos, isn’t even noticeable due to pristine welding and paint.

National Corvette Museum 20th Annual Hall of Fame Induction Ceremony

Chuck travelled to the National Corvette Museum in Bowling Green Kentucky for the 20th annual Hall of Fame Induction Ceremony.
He was invited there to honor his friend and long time racing companion Jim Minneker and Tommy Morrison of the Morrison Motorsports Corvette/Mobile Endurance Racing Series.
Jim Minneker was the Engineering Group Manager for GM High Performance Vehicle Operations. Starting in 1996, Chuck and Jim competed in The One Lap of America multiple times, co-driving Mallett Motorsports modified Corvettes in the events.
Pictured here is the Mallett Motorsports Corvette ZR1 monster race car. It was equipped with a 396 CI splayed value engine using a custom intake system, dry sump lubrication, and a Paxton Novi supercharger with methanol water spray that generated 1449 horsepower, with top speeds over 249.
This car was featured in a story Trash to Flash Nov 1996 Corvette Fever Magazine.
Pictured here left-to-right are Chuck Mallett, Dave Sarafian, and Jim Minneker in Wisconsin heading to their next One Lap event at Road America Racetrack.

Chuck and Jim co-drove the Mallett Motorsports C-5 pictured below the next year in the 1997 One Lap of America race. Under the hood was an untested Z06 engine that would not be released by GM until 2001. This Vortec supercharged LS6 engine produced 600hp that offered drivability and excellent mpg at low speeds, made possible by an M12 6-speed and 3.42 rear end.

A Mallett/Penske coilover suspension combined with Alcon 13.5 slotted disc brakes using 6-piston front and 4-piston rear calipers and PFC pads provided solid handling. This Mallett creation was in a league of its own, running 1/4 mile in 11:30.

The team finished in 2nd place overall in a field of over 180 entrants.

Chuck and his brother Lance raced as part of Hall of Fame inductee’s Tommy Morrison Corvette Endurance team from 1983-1996.

They were instrumental in building and modifying the 1989 ZR1 that broke a 50-year-old 24-hour average speed record. The team averaged 175.8 mph.

The team raced successfully at Daytona, Sebring, Watkins Glen, Road America, and many others.

A great time was had by all honoring the lifetime of achievements by these men. Pictured below left-to-right are: Dr Don Knowles, John Heinricy, Jim Minneker, Chuck Mallett, Dave Ridgeway, and seated is Tommy Morrison.

Mallett Performance Cars headed to SEMA with 2015 700+HP Chevy Colorado

The Mallett Performance Cars team returned to SEMA this year to promote the launch of our 2015+ Chevy Colorado/GMC Canyon supercharger system. We showcased this highly-modified 2015 Colorado with our friends from Magnuson in their booth this year.

This bad boy makes over 700 rear-wheel horsepower, putting out Corvette-equivalent horsepower with four seats and a truck bed.

We swapped the stock engine for a 3.6L V6 from a 2016 Cadillac ATSV. This engine is already built for boost.

The engine features a forged crank, titanium connecting rods, and forged pistons.

Bolted to the top is a Mallett Colorado Intercooled Supercharger Manifold assembly complete with a Magnuson 1.9L supercharger, custom 64mm C&R intercooler, custom CNC-machined upper and lower 8-rib pulleys, front engine idler pulley, tensioner mounting plate, drill-less mounted aluminum intercooler tank and water pump, and C&R heat exchange.

We used a C7 LT1 throttle body to open up the intake side and crafted a custom air intake box. It’s outfitted with a highly custom-fabbed, high-flowing true dual exhaust to polish off the performance mods. This mean machine was fueled with 109 race fuel.

Behind the V6 is a modified stock transmission that turns a narrowed Moser nine-inch rear-end with WaveTrac and aluminum center section. We added Forgeline custom MS3C concave wheels-19x9x.5 front and 20×13 rear, wrapped in rear 315/35/20 BF Goodrich G-force Rivals.

A lot of custom work was put into the chassis and suspension for drivability and stability. We adjusted the ride height to lower the center of gravity. Custom drop spindles were fabricated with custom lower control arms up front. Custom Penske coilover shocks were also installed.

The rear frame section was raised and narrowed, and a custom three-link ladder system with center frame crossbar and driveline hoops were fabricated and welded in.

We installed a custom rear sway bar and adjustable panhard bar were installed to fine tune the truck’s balance. With the size of the rear tires we tubbed the truck bed four-and-a-half inches wider on each side.

The brakes got an overhaul to make sure we could stop this beast. A big thank you to Mike Mecina and Danni Jacobs of Brembo brakes. They came to the rescue with custom Brembo brakes, 6 piston front calipers and 4-piston rear brake calipers with floating rotors.

On the exterior, we removed all the plastic trim, added a custom front grille, and a custom fascia. We added a custom carbon front spoiler for an aggressive look.

Contrast stitching was added to the seats, and Water Buffalo seat inserts. Some trim panels were hydro dripped, and a six Kicker speaker with sub stereo add to the pleasure of driving.

A very sincere thanks to all of our sponsors, vendors, and team members who helped make this vision a reality.

Mallett Supercharger System is Now CARB Certified

Mallett Performance Cars team recently traveled across the country to the SEMA headquarters in Diamond Barr, California.
We trailered our Mallett Supercharged Colorado to California to go through the rigorous, week-long certification process administered by the California Air Resources Board. This process runs through every technical component you can imagine in order to determine whether or not our system is legal to install and operate in all 50 states.
We are excited to share that we passed with flying colors. During the testing process, it was determined that not only did the Colorado run clean and efficiently, it also improved overall fuel efficiency by 4mpg over stock performance.
The Mallett Supercharger system is officially CARB-certified and 50-state legal!

Mallett Team Delivers 900RWHP 2013 ZL1 Camaro

For some people, the 580 crank horsepower from a stock ZL1 Camaro is enough.
Not for Mallett Performance Cars.

Chuck and the team took this stock 6.2L and completely reworked it to make more than 900hp at the wheels. Mallett-spec internals, valvetrain, and cylinder head increased the displacement to 454ci, and a 2.3L Magnuson Heartbeat supercharger with modified intercooler system provided 15lbs of boost.

The exhaust was routed through Mallett long-tube headers with Kooks Hyflow cats and collectors leading to Corsa mufflers with ZL1 cutouts. The fuel system and clutch were also overhauled to manage double the factory output. The fuel system now features upgraded pumps, injectors, and braided lines with AN fittings. The “Mallett Magic” clutch can handle punishment at the drag strip without the punishing feel of a typical high-torque clutch.

The monster drivetrain would be uncontrollable without the complete Mallett suspension package, including custom Mallett/Penske double adjustable coil-overs and a custom drop kit with control arms and upgraded rear springs.

The 20″ Mallett forged split-spoke rims were polished and powdercoated, then wrapped in Michelin Super Sport tires. The factory option Brembo brake package is surprisingly capable and was mostly left alone. The pads were replaced with a Performance Friction offering for aggressive bite with no sacrifice in comfort.

To make this machine look as good as it performs, the team installed a performance hood, a Mallett custom carbon engine cover to complement the polished and powder-coated blower, a Mallett custom carbon splitter, side air dams, spoiler, and framed perimeter grills.

The end result is a car that’s as pleasant to drive as it is to look at. It’s quiet, composed, and comfortable around town, but the drivetrain and suspension deliver stunning acceleration and grip when called upon.
