The science of cooling in motorsports goes far beyond simply mounting a radiator and hoping airflow solves the problem.

That was one of the major takeaways from a recent episode of EPARTRADE’s Race Industry Now webinar series, titled “Perfecting Cooling with Delta PAG,” featuring John Pairaktaridis, President of Delta PAG, and hosted by Brad Gillie from SiriusXM, Ch. 90, Late Shift.

The technical discussion focused on the engineering realities behind modern thermal management systems for racing and high-performance applications, covering everything from airflow efficiency and oil cooling to brushless fan technology, water pump design, packaging constraints, and the importance of approaching cooling systems as fully integrated engineered solutions.
