1,500+ HP Twin-Turbo Lamborghini Aventador Makes Racing Debut with 217 MPH 1/2-Mile

The forced-fed Lambo recently attended a standing half mile event held in Maricopa, Arizona, with the V12 supercar making its debut with a bang. By that, we are referring to the TT supercar’s 217 mph (km/h) trap speed.

While the twin-turbo kit comes from Underground Racing, this is a customer car. This is the tuner’s most extreme Aventador package to date, being specifically built for racing. On pump gas, it allows the V12 to push 1,200 hp, while using race fuel will see the output jumping to 1,550 hp - we’re talking about horsepower at the wheels here.

While the power figures mentioned above are jaw-dropping (or not, depending on how familiar you are with this kind of cars), we want to zoom in on how these ponies are developed.

The tuner throws a billet party, disassembling the Sant’Agata Bolognese V12 to build a race short block.

Here are the steps they use to modify the engine:

• Full blue print and balanced race short block
• Disassemble complete Lamborghini V12
• Bore & hone V12 with torque plate
• Machine block deck surface V12 Aluminum
• Balance complete V12 rotating assembly
• Mallory for balancing crankshaft
• Polish and mic crankshaft
• Jet clean block
• Jet clean cylinder heads
• Custom billet rods
• Custom reverse dish race pistons
• Spiral locks
• Wrist pins
• Oil rail support
• Main bearings
• Rod bearings
• Total seal TNT file fit rings
• Assemble complete Lamborghini V12

The changes are completed by a MoTeC custom engine management system, with boost levels depending on the gear. Speaking of the Aventador’s Integrated Shifting Rods transmission, the clutch is obviously a custom one.

Warranty for the work? Two years or 24,000 miles. And yes, these guys know you’ll be hooning your machine. Heck, they'll even upload the resulting footage to YouTube.
