Underground Racing

What Underground Racing does

Underground Racing LLC is a privately held, US-based specialty automotive performance company (North Carolina; 1-704-361-3443) that designs, builds, and installs custom twin-turbocharger systems for high-end exotic sports cars. Its active product line covers twin-turbo upgrade packages for the Lamborghini Huracán, Revuelto, Aventador, Gallardo, and Murcielago, the Audi R8 (V10 2010-2013 and DCT 2014-2026 variants), and the Ferrari 458 and F430. Each system integrates Precision billet turbochargers, TiAL billet wastegates and blow-off valves, custom air/water intercoolers, aircraft-quality stainless exhaust, and a MoTeC M1 engine management system with custom PNP wiring and dyno/street calibration. Beyond the turbo kits, the company offers in-house engine building (CNC-ported heads, custom billet intakes and engine blocks), billet drivetrain components (DCT/6-speed gear sets, Tilton carbon clutches, billet differentials and driveshafts), high-flow fuel systems, and Penske Triple Adjustable coil-over suspension.

The business operates on a direct-sales, project-based revenue model: customers contact UR by phone or email for quote-based, one-time installations and upgrades, with no dealer network, no subscription product, and no publicly disclosed pricing. Distribution is global (USA and UK explicitly identified) but exclusively direct-to-shop. Customers are owners of exotic Lamborghinis, Audi R8s, and select Ferraris seeking 200+ MPH street-legal performance, and the company has built brand equity through documented records — including a 257 MPH half-mile world record in a twin-turbo Huracán and multiple event wins (King of the Streets 2017, WannaGoFast Dallas, No Fly-Zone vs. Bugatti Veyron).

Commercially, UR monetizes each vehicle as a high-AOV, bespoke project, complemented by an adjacent resale marketplace (URmotors.com) for pre-owned exotic vehicles. The company has no disclosed institutional funding, headcount data, or public financial reporting; it operates as a founder-owned LLC with worldwide reach and a tightly held specialized product line anchored by world-record performance credentials.

Broad incumbents

• Novitec: Established European tuner offering extensive performance and aesthetic packages for Ferrari and Lamborghini. Overlaps on UR's platforms but at much broader scale and with global dealer footprint.
• Mansory: High-end exotic car tuning house with body, interior, and powertrain packages for Ferrari, Lamborghini, and others. Operates at the broader luxury tuning level rather than UR's pure-performance specialty.
• Renntech: Long-established exotic performance tuning house (Mercedes, Ferrari, McLaren). Adjacent rather than direct overlap with UR's Lamborghini/Audi focus, but competes for the same high-net-worth enthusiast customer.
• TopCar Design: Russian-based exotic tuner offering body kits and performance upgrades for Lamborghini, Ferrari, and others. Overlaps in customer segment but emphasizes aesthetics more than forced-induction performance.

Direct peers

• VF Engineering: Aftermarket supercharger/turbo system maker for high-end exotics including Ferrari and Lamborghini. Closely comparable product category (forced induction upgrade kits) and customer base.
• GMG Racing: Performance shop specializing in Audi R8, Lamborghini, and McLaren upgrades including turbo and suspension packages. Directly competes on R8 twin-turbo work that is a core UR offering.
• Fabspeed Motorsport: Exotic performance manufacturer specializing in Ferrari, Porsche, and Lamborghini upgrades including turbo and exhaust systems. Comparable boutique custom-build model with similar customer persona.
• Heffner Performance: Specialty twin-turbo conversion shop for Lamborghini and other exotics. Direct competitor in the same niche of forced-induction builds for Gallardo/Huracán platforms with comparable record-chasing positioning.

Regional players

• Prior Design: European exotic tuner with body and wheel programs for Lamborghini, Ferrari, and other exotics. Comparable customer segment with stronger regional (EU) presence and lighter emphasis on powertrain upgrades.

Emerging players

• BoostLogic: Niche performance shop focused on twin-turbo and engine builds for exotics and high-end platforms. Comparable boutique specialty model with a focus on record-setting builds.
