THE AMERICAN SIDE

A big-cam LS7.
An unmistakable voice.

CRBNUTRL is our silver Chevrolet Corvette C6 Z06, powered by a naturally aspirated 7.0-litre LS7. The big-cam, headers-and-tune combination recorded 563 horsepower at the wheels on the dyno. Black Superspeed wheels, wide Toyo R888R tires and blue ZR1 carbon-ceramic brakes form part of its documented evolution from acquisition to track days.

The planned airflow upgrades are an MSD Atomic intake, a 112 mm throttle body, ported heads and 2-inch long-tube headers. Direct-port nitrous with E85 remains under consideration. The specifications below distinguish those future ideas from the combination used for the 563 whp result.

01 / CURRENT COMBINATION

Cam, headers & tune

A big-cam LS7 with headers and tuning. Dyno result: 563 whp.

02 / PLANNED ENGINE DEVELOPMENT

Heads & valvetrain

Ported heads are on the planned upgrade list, alongside the previously planned Texas Speed LS7R camshaft and 1.8-ratio rockers.

03 / PLANNED AIRFLOW UPGRADES

Intake & exhaust

MSD Atomic intake, 112 mm throttle body and 2-inch long-tube headers.

Planned parts are listed separately from the current dyno combination.

04 / UNDER CONSIDERATION

Direct-port nitrous & E85

A direct-port nitrous system combined with E85 is a possible future phase of the build.

Under consideration; not part of the current combination or 563 whp dyno result.

CRBNUTRL / THE BEGINNING

When we first got it.

The silver wheels mark the beginning of the story—the Z06 as it was when it joined the collection.

CRBNUTRL / WHEELS & TIRES

The setup everyone doubted.

We quickly changed to black Superspeed wheels in a configuration everyone said would not work: 18×10 fronts with 315-wide tires, and 19×12.5 rears with 345-wide tires. Toyo R888R tires, of course.
