Leh Keen’s 997.1 GT3 RS on the Dyno at TopSpeed Motorsports

Leh Keen has been a performance enthusiast for a number of years.  If you haven’t seen Leh Keen’s Rain Dance at the 24 Hours Nürburgring, go ahead and check it out.  We’ll be here when you’re done oogling at some of the most intense driving we’ve ever seen.

Seeing as he gets to drive Porsche Cup Cars on track, a GT3 RS only made sense for a weekend toy.  But this isn’t just any GT3 RS.  It’s equipped with a custom built 4.0L motor capable of producing over 450 whp.  After struggling with the tune for a while, Leh and the guys at TopSpeed Motorsports contacted us about a potential change in engine management software.  With the help of our in-house Porsche Calibrator, Mitch McKee, the guys at TopSpeed Motorsports were able to dial the car in and greatly improve driveability as well as pick up some mid-range power over the previous tune.  Check out the dyno video below!!  The sound this car makes on the dyno is just music to our ears.
