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 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!

800hp 2014 Retro Chevy Silverado1500 Mallett Super10 Heads to SEMA

The Mallett team headed to the annual SEMA show in Las Vegas Nevada this year. We showcased our 800hp, retro-designed Chevy Silverado in the Kooks Headers and Exhaust display booth.

It all began with a phone call to General Motors to order a ’14 Silverado 1500 Z71 4WD double cab in factory red. The plan was to build a lowered truck, but the only way we could get the larger Silverado motor – the 6.2L V-8 – was to get a 4WD version. We would have to fabricate needed parts in-house at the shop. We were going for a ’70s-themed truck that would have the classic two-toned look, combined with modern luxury and performance.

Lowering this 4WD was a challenge at first, since no one made a lowering kit for the new body style 4WD and the 2WD version wasn’t an option for us. We took a McGaughys 2WD front drop kit and machined it to fit the 4WD truck.

In order to get a retro-looking wheel to complement the look we were going for, we chose a set of 22-inch Centerline Smoothie wheels that were painted red to match the truck and wrapped in 285/40/22 Yokohama tires.

A set of ’55/’56 Chevy repo hubcaps were machined by Bob Temple to fit the new wheels and were mounted on custom tabs. Under the truck, the entire frame was cleaned and sprayed with Dupli-Color bedliner.

Now that the truck sat in a lowered stance and the rolling chassis was ready to go, it was on to the body. First we removed the plastic caps on top of all the bedrails and the top of the tailgate. Jim Callaro at Metal Masters in Mooresville, North Carolina, welded in metal replacements for the plastic panels. This gave the bed a smoother look and allowed the paint to carry over the top of the bed. The next step was to completely rebuild the front and rear bumpers to remove all the plastic pieces and make them match the look of a ’70s Chevy.

There were more than 200 hours in custom fabrication in both of the bumpers. Sun Stoppers Chrome Wrap and Window Tint in Cornelius, North Carolina, wrapped both bumpers in chrome. To continue, the Mallett team built custom side trim moldings to resemble the old Chevys. We used 3003 sheer aluminum that was bent on a break, welded and hand-filed to mimic the ones from 1972. Then, they were masked off and a black center was sprayed to complete the look.

For the tailgate, a retro “Chevrolet” center plate was made. Then, the truck was off to Lake Norman Paint & Body in Cornelius, North Carolina, where Mike Pelusi painted the center of the truck PPG Summit White and painted over the new bodywork on the bed, finalizing that ’70s look.

Once painting was completed, final touches like the custom egg crate grille insert made from welded aluminum plate and the chrome bezel taillights from Razor Auto were bolted on.

Now it was on to bring the retro look into the interior as well. The factory black leather seats and door panels received houndstooth inserts, thanks to Robert McCarter in Harrisburg, North Carolina, which mimics early ’70s Chevy. All of the dash and door trim pieces were sprayed chrome to complete the retro look.

Saving the best for last on this build: the performance add-ons.

Starting with the factory 6.2L V-8 engine, the block was fully race-prepped, balanced, and blueprinted. A Callies billet crankshaft, 6.152 Ultra I-beam billet rods, Wiseco Gen 5 LT1 10:1 pistons and JGK 4.065 rings made the bottom end of an already beefy engine bulletproof.

A COMP Cams custom cam was ordered to allow better fuel flow. The motor was ported by Advanced Induction/Cylinder Head Development in Concord, North Carolina. ARP head stud kit and wrinkle black valve covers wrap up the top end of the motor.

To spit out the spent exhaust gases, a set of Kooks long-tube headers and a complete Kooks 6.2L cat-back 3-inch exhaust with custom tips were bolted on.

Next we added a Whipple 3.0L supercharger with 13 pounds of boost along with a custom ECM tune that was done in house. A set of Accel Extreme 9000 Ceramic plug wires round out the performance additions.

A 6L80/6L90 was built by RevMax in Charlotte, North Carolina, to get all that power to the ground. Speaking of power, with all the internal upgrades along with the blower and new exhaust, this truck puts down right at 800hp to the rear wheels.

All the attention to detail in the build was rewarded, we were very proud to win the highly sought after GM Design Best Truck award at the 2014 SEMA Show. This truck is now at its new home, and we have already started on our ’15 Chevy Colorado project for the 2015 SEMA Show. Stay tuned for more!
