Heffner Performance has increased the already powerful Lamborghini Murcielago by customizing the engine bay with a twin turbo setup. After all the car tuning was performed, the new Lamborghini Murcielago produces 1100 hp at the rear wheels when boosting 14.5 psi. It has great track results for the 60-130 mph time at a mere 5.1 seconds, but Heffner Performance did not mention the 0-60 mph time. We’re guesing it’s due to traction issues, considering it doesn’t have all-wheel-drive to keep the wheels on the pavement. They are not finished with the car yet, however, they believe some extra tuning and tweaking could produce hidden power. The guys from Heffner have completed some impressive work on a Ford GT in the past, and now this Lamborghini Murcielago Twin-Turbo has received some fine tuning.
