Tech Heads F1 Podcast - Ep. 4 (Juan Manzanero)

In Episode 4 of the Tech Heads F1 Podcast, co-hosts Bryson Sullivan and Dr. Obbs are joined by Juan Manzanero (aka @fastestlap_f1), an extremely talented engineer and author of the excellent "Fastest Lap" open source lap time simulation software. With Juan as our guide, we explore the technical nuances of vehicle dynamics and optimal lap time simulation, covering G-G plots, brake balance and bias, tyre load sensitivity, and what goes into calculating driver inputs for a theoretically perfect lap. In this week's "Tech Focus" segment, we talk exhaust blown floors from the 2012 season, how teams exploited the Coandă effect to recover the downforce lost from the removal of exhaust blown diffusers, and we answer listener questions. This is a longer episode, but it's absolutely packed with quality F1 Tech content we think you won’t want to miss, enjoy!
