Underground Racing 2R R8 5.2 V10 build puts down a jaw dropping 1831 horsepower to the wheels
Now this is big boy horsepower. Most readers are aware that Underground Racing twin turbo Gallardo V10 builds have shown some absurd horsepower with 2000+ horses at the crank. The Audi R8 5.2 V10 has the exact same direct injected V10 motor as the newer LP-560 Gallardo's so on paper it should be capable of the same horsepower. Here is the result and proof in practice with an Underground Racing R8 5.2 2R hitting 1831 horsepower to the wheels.
Yes, that is on race gas. What about on pump gas? How about 1150 horsepower at the wheels on 93 octane. A 1000+ wheel horsepower daily driven R8 is easily within reason.
A Motec JRR ECU makes this all possible along with a strengthened drivetrain consisting of a billet diff and gears. Check out the dynograph and photos below. Much respect to Underground Racing for building the strongest R8's in existence.
