Video: Freakish 993 Turbo Battles 997 RSR at Road America

Sure, they’re both Porsche 911s, essentially, but the two machines come from different worlds. Though some might think the silver 993 is a roadgoing Turbo-turned-track toy, it’s actually a tube-framed machine with an outrageous motor hanging off the rear.

Not surprisingly, it becomes a low-flying jet once those turbochargers spool up, and there’s not much that can hope to hang with it on Road America’s long straights. Though some people would criticize its owner for needing to purchase horsepower to win, the silver 993 demonstrates some of creative liberties people can take in a club racing environment.

In contrast, the camera car was borne out of strict regulations and designed to race in mega-competitive categories worldwide. This 2007 Porsche RSR, kept in-check with an intake restrictor, generally makes 465-485 horsepower. But, with a flat torque curve and a sequential gearbox, the RSR is exceptionally quick after the apex. In fact, it repeatedly nuzzles the 993’s bumper until those turbos spool and render the silver machine a speck on the horizon.


Though the above footage is not of the same event, it shows just how well it puts down some 800 horsepower.

The RSR’s superior cornering and braking are evident throughout this chase; the difference most notable during RSR’s passing attempt through Turns 9 and 10 (1:33). Squeezing past around the outside of a quick corner requires some faith in the machinery, agility, and gobs of grip. Clearly, there’s no shortage of poise with the RSR.

Neither car is giving an inch and defending their corners, and even though this is a scrap between two club racers, it’s clear they’re not there for giggles.
