Inside the right-hand-drive Tommykaira R, the driver is surrounded with evidence of the machine's pedigree. The stock vise-tight bucket seats and stock rear seats are trimmed in trademark Tommykaira red, and there's a Tommykaira steering wheel that's sublime to squeeze. In front and in plain sight is the Tommykaira gauge cluster, which houses, among other things, a 10,000-rpm tachometer with a lofty 8000 rpm redline. Tommykaira also mounted three gauges in a carbon-fiber surround, detailing boost pressure, oil temperature, and by far the coolest one, torque distribution between the front and rear wheels.
To the right of the steering wheel is the ignition. When the key is twisted, the car comes to life with a bark from the A'PEXi N1 downpipe and Tommykaira exhaust, then settles into a glass smooth 900-rpm idle. Thanks to Charles having deleted the catalytic converter and adding an A'PEXi intake, the TKR's voice is slightly more pronounced when clearing its throat, but it's far from obnoxious. This is one of those rare cars with more bite than bark. The slightly massaged twin Garrett turbochargers and 50-percent larger than stock Tommykaira intercooler extract a claimed 465-crank hp from the 2.6-liter engine.
