Incredible on-board lap of Laguna Seca in a Porsche 935 K3

Leh Keen grapples with 800bhp of turbocharged, oversteering monster round the daunting inclines of the Mazda Raceway

The sound, the oversteer… We know it’s only Monday but we doubt you will see a cooler on-board video this week. The video is a few months old, but as not a huge number of people have seen it we thought it had to be worth flagging it up.

The car is a 1980 Porsche 935 K3 being driven round Laguna Seca (otherwise known as the Mazda Raceway) during the Rennsport Reunion last October. The K3 was the most famous of the 935s tuned by Kremer Racing, based in Cologne.

Weighing less than 1000kg (970kg was the minimum required by Group 5 rules) the 935 K3 had a twin-turbo flat-six putting out between 720bhp and 800bhp through a four-speed gearbox. The result was one of the wildest cars ever produced.  In 1979 a K3, in the hands of Klaus Ludwig, won a very wet Le Mans 24hrs, beating not only all the prototypes, but also a factory spec (although not factory-run) 935 into second place.

The man behind the wheel battling the boost is 32-year-old Leh Keen, who drives a 991 GT3R during his dayjob as a driver for Alex Job Racing. He also has a pretty amazing collection of 911 road cars, which you can see on his Instagram page
