You may recall that we first reported about British sports car manufacturer Keating and its new supercar duo, the respective SKR and TKR, back in April of 2008.

At the time, Keating was boasting that the more hard-edged TKR would be capable of breaking the world land speed record for a production car, which was then held by the Bugatti Veyron.

At this year’s MPH Auto Show in the UK, Keating was claiming that its TKR supercar had posted an “unofficial” top speed of 260.1 mph in a round of testing that took place last month at California’s Salt Lake Flats.

In the first of two runs on the Salt Lake Flats, the 7.0-liter, 1,800 horsepower TKR reportedly smashed the current record, adding an extra 3.0 mph to the top speed of existing title holder, the SSC Ultimate Aero TT. Now, Keating must do it again to ensure entry in the Guinness Book of World Records.

The TKR, and its more subdued SKR sibling, are based around the same basic chassis, consisting of a steel spaceframe structure (or optional carbon-fiber) and a GM-sourced V-8 powertrain. The car’s body panels can be ordered in either fiberglass or carbon-fiber and the only transmission option is a 5-speed Porsche transaxle, which channels power strictly to the rear wheels.

There are two different engines to choose from--a 6.0-liter or 7.0-liter GM V-8--and both come either naturally aspirated, supercharged or turbocharged. Keating is still taking orders for the car, which is expected to enter production in limited numbers by the end of the year.
