AMS is known for making big power and low ETs with cars that are already pretty darn quick from the factory. The Alpha Omega GT-R comes to mind, which recently ran a standing quarter mile in 7.7 seconds at 186 mph.
Never content to leave good enough alone, the Chicago-based tuning shop has now had its way with the engine software on the McLaren 12C, bestowing the English supercar with an extra 100 horsepower and 125 pound-feet of torque. When paired with a set of Nitto drag radials and 93-octane fuel it makes for a 10.1-second quarter-mile at 138 mph, numbers that AMS claims make it both the fastest and quickest 12C in the world.
However, all that extra power doesn’t come cheap, as AMS is asking for $6,000 for a single remap service. But considering how the McLaren cost just under a quarter-million bucks when new, a couple grand shouldn’t be much of an issue.
Overall, it’s quite impressive to think those kinds of gains are accomplished with such simple modifications. Odds are we’ll be seeing new upgrades for the 12C from the AMS crew very soon. Only a few tenths separate the current tune from a single-digit quarter-mile, which means the world’s first nine-second 12C is probably just a few well-engineered engine mods away.
Click past the jump to read more about the McLaren 12C.
Between 2011 and 2014, McLaren offered the MP4-12C, now known as just the 12C. Featuring the same twin-turbo, 3.8-liter, M838T V-8 engine found on the imposing P1 halo car, the 12C comes in a stock guise with 616 horsepower and 476 pound-feet of torque, the total of which meets the ground via a seven-speed, dual-clutch automatic transmission for a 0-to-60 time of 3.1 seconds and a quarter-mile time of 10.6 seconds.
Of course, this mid-engine monster is far more than just a drag racer. Put a driver with properly trained extremities behind the wheel, and the 12C is a highly capable slayer of lap times. Curb weight is around 3,000 pounds, thanks to a one-piece carbon-fiber tub, heaps of aluminum, and Formula 1-inspired design.
Throw onto this package a dynamic airbrake, highly adjustable suspension, and AP Racing six-piston calipers equipped with brake steer, and you can see how the 12C is sure to be a stout competitor in any form of speed contest. Why AMS would want to just drive this thing in a straight line has me a bit confused, but hey, I’m not complaining. More power is always better in my book.
