Supercharger pulley + 82° Thermostat

Increasing performance often means increasing heat—and when running a smaller supercharger pulley, managing that added thermal load becomes critical. A reduced pulley diameter spins the supercharger faster, generating more boost and significantly higher engine temperatures. Without proper cooling upgrades, this excess heat can lead to inconsistent performance, accelerated component wear, and long-term engine damage.
That’s why pairing a smaller pulley with the KAVS Motorsport Thermostat is the ideal solution. Developed through years of real-world road and track testing, this thermostat is engineered to open at a lower temperature of 82°C (180°F) and operate with a smoother, more linear actuation than factory thermostats. This allows coolant to circulate through the engine sooner, helping to control rising temperatures before they become a problem and maintaining a cooler, more stable operating range under increased load.
Designed as a direct fit for 2002–2008 MINI models, the KAVS Motorsport Thermostat is digitally calibrated and manufactured using high-quality wax to ensure precise, consistent opening temperatures. Each unit includes a gasket for a clean, leak-free installation and is built to perform reliably even in the most demanding driving conditions.
When combined with a smaller pulley, this thermostat becomes an essential supporting upgrade—helping unlock additional performance while protecting engine longevity. Backed by KAVS Motorsport warranty, it delivers confidence, durability, and proven cooling performance for both street-driven MINIs and track-focused builds.
