1963 Twin Turbo Corvette “TwinSting”
This 1963 Twin Turbo Corvette was featured on Boyd Coddington American Hot Rod TV show. The producers of the show added a dramatic twist by setting the completion date for this Corvette in an unrealistic time frame of just 2 months. Adding drama to a TV show is commonplace in “Reality TV”, however, it is unfortunate the network added the drama because it took away the ability for the viewers to appreciate the details of this hot rod and how much work went into those details. The car’s owner, stated that he has always loved the lines of the Sting Ray ‘Vette, and the ’63 split-window was his favorite design, and chose the Sting Ray as he considered it to be the perfect starting point for a high-horsepower modern Pro-Street car.”
The customer reiterateted that he needs a high-quality car with amazing power but still be able to use as a driver. He also said that the reason he chose Boyd Coddington Garage to build this car, is due to our reputation of high quality craftsmanship in addition to the fit and finish that is associated with the Boyd Coddington Shop.
The most important aspect of building a good engine is to use the highest quality components you can get. That said, at the heart of the power plant sits Carillo forged connecting rods and JE 28cc slugs to fill the 4.155 bores. A Cloyes double-roller timing chain keeps things working in the right order and a custom ground Nelson camshaft that calls the valves to action inside the DART aluminum heads.
The intake manifold is manufactured from billet aluminum which features twin 62mm throttle bodies. Every nook and cranny of the engine bay is full of horsepower generating parts. So full, the headlights had to be removed to make room for the twin turbo’s. Attaching a pair of external headlights to the front bumper facilitated lighting at night, an insignificant sacrifice for an engine that will put out 1,500 hp and 32 pounds of boost.
In order to keep it all together under that much boost, we had to O-ring the block and mill receiver rings into the heads to keep it sealed for any pressure over 30 pounds. In addition, the exhaust valve guide clearances had to be set to exacting tolerances. The side pipes were manufactured with two additional aspects in mind; exhaust note, and ground clearance.
The sheer amount of fabrication carried out on the body is partly responsible for any delay in building the car. The headlight buckets were filled, one-piece windows were fabricated, and the door handles removed. Other modifications include an aluminum louvered belly pan, and the hidden radiator air scoop. We designed an aluminum hood to look like the big-block hood of the 1967 Corvette combined with the modern billet associated with the Boyd Look™. With the body completed and Charley Hutton off to work for Chip Foose, Boyd jumped into battle gear, into the spray booth and painted the car himself, (first time in 25 years) in House of Kolors Kosmos Red.
Gabe Lopez covered everything in the interior of the car with tan leather and suede. Gabe also went ahead and hid the cage under the headliner and pillar panels. Hot Rod Air provided air conditioning system for cooling the driver and passengers. No stereo system, it was decided you probably couldn’t hear it anyway with all the horse power flowing out of the rear. Inside the cockpit the vital parts of the engine are monitored by Autometer gauges and the steering wheel we made in-house at Boyd Coddington Garage.
TwinSting displays the quality and expertise that you would expect from an Authentic Boyd Coddington built hot rod and is truly art on wheels.
