Please read our FAQs page to find out more.

Will upgraded cooling help repeated laps in a VR30 Q50?

Yes—higher‑efficiency radiators and larger front heat exchangers reduce engine and charge‑air heat‑soak. Proper ducting and fan shrouds improve airflow.

Is an oil cooler necessary for hard driving?

Aggressive canyon/track use benefits from thermostatic oil cooling and proper airflow. Shield lines near hot components with heat sleeves.

How do I fight charge‑cooler heat‑soak on hot days?

Seal shrouds, improve airflow, upgrade the heat exchanger and pump, and keep the A/C condenser clean to minimize pre‑heating of charge air.
