Charlotte, NC-based Underground Racing likes to slap turbos on exotic cars. We’ve known this for a while given their long track record of boosted Gallardos and Audi R8s. And, while we’re always most entertained by the firm’s creations, this R8 GT with claimed 1,800 hp has us particularly mind-blown.

Here’s a rundown about the car, posted by Underground Racing on their Facebook fan page on Christmas Eve.

This is the first Stage 2R Twin Turbo Audi R8 GT that we have completed here at Underground Racing. The customer went with the FULL 2R build. This setup makes an easy 1,150 whp on 93 octane pump gas and over 1,800+ whp on race gas. This TT R8 GT has the JRR Plug & Play Motec ECU system with custom Egear harness. Drivetrain is setup with the full billet 1-6 custom ratio, billet input/output shafts, billet final drive gears and a helix billet deferential just to name a few goodies. This TT R8 has the latest Underground Racing full billet intake that as been anodized black. This should give some of the big power TT Gallardos a great run once the owner gets some seat time. Expecting to see videos of this beast in action very soon!
