What would happen if you took an IndyCar inspired chassis, dropped a 1973 Pontiac Firebird body over the top of it, and then added a 1,450hp twin-turbo LS? That’s essentially what Cavan Cameron and his father, Russell Cameron, of Horizon Motorsport have built.

The project began as Cavan’s high school engineering project but has since evolved into one of the coolest and most ambitious builds we’ve seen in a while.

In this episode of Tuned In, Cavan shares his journey from a childhood passion for cars to pursuing a career in motorsports engineering, sparked by his father’s involvement in IndyCar.

We dive into the “Hammerhead” build that Cavan and his dad have been developing, exploring the challenges of integrating genuine IndyCar components into a bespoke project. He breaks down the technical aspects of the tube-frame chassis, from fabrication and material choices to the complexities of suspension dynamics.

We cover the finer details of designing and developing a competitive race car, with a focus on suspension, engine configuration, and aerodynamics. The conversation also touches on the challenges faced during its first outing at World Time Attack Challenge, including managing torque through the transaxle and tuning the car for optimal performance.

This build is truly something special, and what Cavan has achieved is seriously impressive. We can’t wait to see how the car evolves as they continue to refine and dial it in.
