Heffner Performance’s standard twin-turbo package for the 5.0L high-rev V10 engine of the Lamborghini Gallardo was already one of the most extreme tuning packages for any car, let alone an Italian exotic, but the Florida tuner has lifted performance yet again. This time around, power has been boosted to an insane 1,005hp (750kW) at the wheels and torque has been bumped up to 765lb-ft (1,036Nm).After an initial build, the car ‘only’ churned up 930hp (694kW) at the wheels but its owner, Allan Fiedler, was determined to reach his original target of delivering more power at the wheels than the Bugatti Veyron develops at the crank. After spending more time with the car, Heffner’s engineers managed to reach the target and have provided the dyno chart to prove it.
Power is sent to all four wheels via the Gallardo’s standard AWD system but to ensure some level of drivability remains, a two stage boost controller limits boost in 1st and 2nd gear to useable limits.
As expected, modifications to the standard Gallardo are extensive. Starting with a complete engine removal and disassembly, Heffner installs steel cylinder liners, new forged pistons, polished crankshaft journals, new bearings, a new twin-turbo system with custom exhausts and intake systems, twin wastegates and blow-off-valves, 1,000hp-rated Carrillo Billet Steel connecting rods, a twin-stage electronic boost controller and a heavy duty clutch to transfer all that power.
To make sure everything runs smoothly, Heffner also installs uprated fuel and water pumps, fuel-injectors and a water-cooled intercooler system. Styling enhancements include a carbon-fiber rear decklid and a Superleggera-style rear diffuser and spoiler. The car’s final kerb weight measures in at 3,377lbs (1,531kg) with half a tank of fuel.
While no track numbers or quarter mile times have been posted, with more than 1,000hp spinning up the wheels the car could easily be the fastest Lamborghini in the world.
