800 HP Heffner Twin-Turbo Lamborghini Gallardo Gets a New Set of Lungs - Dyno Run

Stock (Factory Rated Flywheel Power): 520 HP SAE @ 8,000 rpm 376 ft lb @ 4,250 rpm The Heffner Twin turbo system primary components consist of: - (2) Ball Bearing "Precision turbo" turbochargers - Air/Water Intercooler, Intercooler pump, and front mounted heat exchanger - Running a "modest" Boost level of 6 psi, and 91 octane pump gas running through its veins. Dyno Measured Results @ the Wheels: 592 Wheel HP @ 7800 RPM 450 Wheel TQ @ 4700 RPM What is the VERDICT? Let's convert from Wheel HP to Flywheel HP: our powertrain loss on our Dyno is 35% for an AWD Lamborghini Gallardo: 592whp X 1.35 = 798.4 flywheel HP 450wtq X 1.35 = 607.5 flywheel TQ Considering our "Fruit Punch" Arizona blend 91 octane fuel, we would say that Heffner was right on with their 800 HP "bolt-on" kit!

Day 1: Picking up my new Gallardo at Lamborghini Newport Beach!
I found the perfect Lamborghini Gallardo and bought it at Lamborghini Newport Beach in California. Picking it up at the dealership to drive 1,200 miles home! It's a 2006 Lamborghini Gallardo with 9,500 miles, 6 speed manual transmission finished in Arancio Borealis. It has a 5.0L V10 that produces 520hp! I am the second owner of the car after the original owner owned it for 10 years.
