CarBarn BMW M8 Competition From Steven Dinan Is A 900-HP Beast

The BMW M8 Competition is an absolute beast of a thing but for noted tuner Steve Dinan, he thought it could do with a little extra oomph.

Dinan recently established a new company dubbed CarBahn Autoworks and has just announced its first project, based around the M8 Competition. The upgrades look to transform all performance aspects of the car.

The package adorning this M8 Competition is dubbed the ‘GT’ kit and has seen power from the 4.4-liter twin-turbocharged V8 increased to an extraordinary 882 hp and 795 lb-ft (1,077 Nm) when running on 100 octane fuel or 824 hp and 779 lb-ft (1,056 Nm) on 93 octane. These figures have been achieved thanks to larger heat exchangers and intercoolers, new air filters, and some software tuning.

Elsewhere, CarBahn’s GT kit includes new coil springs that lower the ride height by between .5-inch and 1-inch. There are also 4-way front and 3-way rear adjustable tubular anti-roll bars, negative camber control arms and camber adjusters. A wheel and tire package has also been developed, complete with 20-inch shoes from Forgeline wrapped in 295/30 Michelin Pilot Sport Cup R tires at the front and 305/30 Michelin Pilot Sport Cup R tires at the rear. This package costs $13,700 while the wheels and tires add $9,200.

The second package developed is dubbed the GTS and results in 850 hp and 795 lb-ft (1,077 Nm) on 93 octane and 940 hp and 795 lb-ft (1,077 Nm) on 100 octane. It includes the same suspension upgrades but also has larger turbochargers and features meth injection. The GTS pack costs $23,700, excluding the aforementioned wheels.

The Full Fat 900-HP Package

Last but not least is the GTC pack with 900 hp and 795 lb-ft on 93 octane and 1,000 hp and 795 lb-ft (1,077 Nm) on 100 octane. It features further engine modifications as well as all the same upgrades as the GT and GTS packages. Prices for the GTC package start at a cool $43,000.

CarBarn Autoworks will offer the same upgrade packages for the BMW M5.
