If you’re no stranger to Corvettes, then you might be familiar with the fact that the C7 Z06 has developed an unfavorable reputation for succumbing to heat soak when being driven as intended on the track. In what has to be its C7 Corvette Z06 even infamously ruined itself at the MotorTrend car of the year testing because of overheating. That being the case, Callaway Cars offers up a solution, in the form of the C7 Corvette HD Cooling System.
The Callaway Corvette HD Cooling system was co-developed by Callaway Competition of Leingarten, Germany, and Tikt Performance of Stephanskirchen, Germany.
How To Make the Z06 Better
So, this is obviously a major issue if you’re putting up the money these go for, so what do you do if you don’t want your Corvette to overheat when doing the thing it was designed to do best? You get the Callaway HD Cooling System.
Installed only by Callaway techs, the HD cooling system comes into 2 stages with a front cooling grille emblazoned with the Callaway name. The grille forces air into the intake and into braking components to aid the cooling process and is also available as a stand alone.
Stage One of the cooling system includes the HD Cooling grille, a high flow-rate intercooler pump offering 35% more flow than stock, high flow thermostat assembly and an intercooler with increased capacity. Stage Two includes all of the above plus a carbon fiber splitter, a carbon fiber undertray that connects to the sub frame while directing airflow to the brakes, an air-to-oil heat exchanger that replaces the factory oil-to-water exchanger and lightweight braided polymer oil lines to round out the second stage.
All of these upgrades produce quite the difference when you’ve got your C7 Corvette Z06 on the track. According to testing conducted on both the Callaway SC627 and SC727 Corvettes as compared to the same Corvettes with the Stage 2 Cooling upgrades installed, the added cooling upgrade allowed the driver to spend around 19 minutes on the track before the test was called.
The default C7 Corvette Z06 without the cooling upgrades made it 5-6 minutes before having to do cool down laps and/or entering limp mode.
Callaway offers installations in Connecticut and California, and if you’ve got another 20ish grand USD to spend on an $85,000 car, you better spend it.
