This car is the world’s first second-generation R8 to get a twin turbo treatment – or any substantial engine upgrade treatment for that matter. The car is still in the works and the tuner is putting the final touches on it, but this Underground Racing Audi R8 Twin Turbo is going to be one badass machine when it’s launched as it gets up to 2,200 horsepower in the full-fat racing version.
But that’s not where UR begins. They begin with a “Base” twin turbo program in which their 2017 Audi R8 Twin Turbo with the stock ECU makes 800 whp (power at the wheels) on pump gas. This package costs $49,000 installed. Stage 1 is pretty much the same but costs $59,000 because it is racing fuel enabled and on which it delivers 900 whp.
Then we get to stage 2 twin turbo package which starts at $69,000 and offers 850 whp on pumps gas and a nice and round 1,000 whp on race fuel. Moving on to stage 3, some serious engine modifications happen here in order to give you 1,000 whp on pumps gas and 1,250 whp on race fuel. This one sets you back a whopping $99,000 installed. A race version of this kit ups the output to 1,150 whp and 1,500 whp respectively.
