In his view, rotaries can be among the most reliable engines when properly understood.👉 Use the code ‘PODCAST500’ to get $500 OFF HPA's VIP Package: https://hpcdmy.co/podvipIn this episode of Tuned In, David shares his journey from a childhood fascination with technology and cars to becoming a rotary engine expert. He discusses the challenges and rewards of owning and daily-driving his first RX-7.We dive deep into rotary tuning, starting with the fundamentals—air-fuel ratios, exhaust gas temperatures, and the critical relationship between ignition timing and engine reliability. David also shares his views on engine building, apex seals, and porting, and explains why rotaries deserve a far better reputation than they’ve been given.We explore the evolution of his five-rotor engine, what it took to bring such an ambitious project to life, and the challenges of building something this complex. David breaks down the science behind its unforgettable sound and reveals how his background in music helped him dial in and replicate the pitch of an F1 V10.David’s passion for the rotary engine is undeniable. He’s a wealth of knowledge, and what he’s achieved with his MF5 Superlite is nothing short of extraordinary.
