At the SEMA show this year, the German tuner is
presenting the Gemballa GT Concept, based on the 911 Turbo but tuned up to 828
horsepower instead of the standard 540.
To squeeze out that much power from the 3.8-liter
twin-turbo flat-six, Gemballa has replaced the intake manifolds, cylinder
heads, valves, air filters, connecting rods, turbochargers, exhaust system, and
more. Much, much more.
Gemballa's also fitted a full aero kit, complete
with a new front bumper, splitter, side skirts, fender flares, rear bumper,
diffuser, wing, and engine bay cover – much of it made out of carbon fiber. It
all sits on a set of 21-inch forged alloys – over a foot wide at the back –
packing 380-mm discs with six-pot calipers at the front and 360-mm discs with
four-pot calipers at the back. The sum total of all these improvements? 0-100 km/h in under
2.4 seconds and a top speed in excess of 354 km/h.
Though billed as a “concept,” Gemballa will sell
these upgrades to anyone with the cash on hand as part of its GTR 8XX Evo-R
BiTurbo program – but it won't come cheap. The aero kit goes for € 25,450, the
rolling stock for € 7,150, the engine upgrades for € 49,800, and the optional
carbon-fiber airbox for € 3,880. That's over US$ 100,000 in upgrades alone, on top
of the price of the donor Turbo, which itself starts at US$ 161,800.
