Carrera RSR IROC: The Sensory-Overload Porsche 911 — The Carmudgeon Show w/ Cammisa & DTS — Ep. 220

2026 has begun - and we’ve already had a healthy mix of highs and lows. But Carmudgeonation carries on, this week bringing along some pretty heavy metal that ISN’T an IROC-Z Camaro - rather, the 1974 Porsche Carrera RSR IROC. === Visit http://JasonSentMe.com to get a Hagerty Guaranteed Value (TM) collector-car insurance quote! === Jason is nearing the finish line on his MK3 VW Cabrio VR6 swap - with much of the car torn apart and roughly put back together again, he discovers a fatal engine flaw that will put him back quite some time. While the VR6 runs, a bastardized time-sert has cracked the head - pushing Jason to make the decision to go big and begin the process of a full Techtonics VR6 engine build. But not all in the land of 6 cylinders is lost. Derek and Jason kick off the new year by driving an iconic race car that happens to be road-legal - the 1974 Porsche Carrera RSR IROC. A car they both agree, is perhaps the most extreme 911 either of them has ever driven. The story goes - in October of 1973, Roger Penske took delivery 15 of special 1974 cars in Riverside California, which had been built to his order. He acquired the cars to participate in the first ever International Race of Champions (IROC), which was actually a series of four races, three at Riverside in late October and the final race at Daytona in February of 1974. The cars would be driven by a dozen of the best racing drivers in the world, hailing from different racing disciplines including Indy, Can-Am, NASCAR, and Formula 1. In the hands of George Follmer and Mark Donahue at Riverside International Raceway, this particular car won twice - more than any other of the 15 cars it competed against. All this and more, on this week’s episode of The Carmudgeon Show.
