Turning the Key of the 912C

Twist the key, and the 912C’s little flat-four clatters into life. In its original form, the Porsche 616 engine displaced 1.6 liters and produced 90 horsepower. The 2.0-liter Kamm version shares the original engine’s architecture, but it’s essentially a new engine that has been developed in conjunction with high-performance powertrain specialists BDN Automotive. More than 200 virtual iterations of the Kamm 616 were tested before the chosen physical version was put through more than 10,000 hours of dyno testing. Apart from bigger bores, the Kamm 616 features redesigned cylinder heads, a new camshaft, bespoke throttle-by-wire fuel injection, and a redesigned exhaust. Its 182 hp is developed at 6,500 rpm, with peak torque of 180 lb-ft arriving at 4,500 rpm.

The engine drives through an upgraded version of the 901 dogleg five-speed manual transmission actuated by a tall carbon-fiber shifter. Depress the floor-hinged clutch pedal on the state-of-the-moment AP Racing pedal box and pull the shifter across and back to select first gear. Ease in the clutch, and the 912C moves smoothly away. Despite its racy demeanor, with 110 lb-ft of torque on tap from 2,000 rpm, the lightweight Porsche is easy to drive at low to middling speeds—2,100 rpm in fifth gear is 50 mph—while you to get to know its idiosyncrasies.

The gearshift is notchy, but there’s too much friction in the action to make it feel like a well-oiled rifle bolt, a result of the stiffer springs and bushes fitted to make the notoriously sloppy 901 transmission feel a little more concise. Kázmér says the springs and bushes can be changed to suit your tastes. And while we’re picking nits, the brake and gas pedal heights need adjusting to make heel-and-toe downshifts easier.

The Kamm 912C’s 15-inch wheels are shod with Yokohama Advan Fleva tires, 195/55 at the front and 205/55 at the rear. Those generous sidewalls, combined with the adjustable semi-active coil-over Tractive shocks set to the softest of their five settings, deliver a good low-speed ride. The front suspension features control arms from the later G50 911, but the rear geometry is old-school 912. And you can feel it when you start to push the Kamm 912C.

Driving the 912C Like Crazy

Twist the knob adjacent to the ignition key to stiffen the Tractive shocks. There’s a knob next to it cryptically labeled DMC. Pull it to activate what Kázmér calls “Drive Me Crazy” mode to open flaps in the exhaust system, which helps the engine breathe better. And make more noise. The little flat-four likes to rev, the clattery chatter from behind you becoming a calico-shredding snarl as the tach needle swings past 4,000 rpm, building in intensity all the way to the 7,200-rpm redline. You don’t get a big shove between the shoulder blades when you mash the gas. But with the same power and 30 lb-ft more torque than a Mazda Miata propelling a car two-thirds the weight, the Kamm 912C feels lively on real-world roads.

That liveliness is accentuated by the Kamm 912C’s old-school dynamics. Compared with modern 911s, cars whose rearward weight bias has been pretty much tamed by technologies such as stability control and rear-wheel steering, the Kamm 912C makes you clearly aware its engine—though 50 pounds lighter than the flat-six that powered contemporary 911s—is hung out behind the rear axle. The unassisted steering is light and alert, but you need to make sure you load the front axle on corner entry, lifting off the gas and braking, to get the car to turn in. Then, as the mass of the engine out back begins to accelerate the rate of rotation, you need to get back on the power and transfer weight onto the rear wheels to drive you out of the corner.

The transients aren’t as pronounced as in a 911. But hustling the 912C rapidly down a winding two-lane still requires more interaction with the steering and braking and transmission and throttle, more understanding of the art and science of driving, than in, say, a modern Miata or Porsche Cayman. And that’s exactly how it should be. The Kamm 912C is a proper old-school sports car—compact, light, and wieldy, joyously analog and utterly engaging—even when driven at normal road speeds. The Kamm 912C is proof positive that you don’t need mega horsepower to have fun or hone your driving skills. Yes, less can give you more.
