Few would doubt the fact that the Lamborghini Gallardo with its V10 and the Ford GT with its blown V8 are fast right out of the box. However, owners who want more than stock performance can get it at Heffner Performance. Motor Trend tasted two sweet rides from Heffner that use twin-turbo chargers.The Gallardo is available in two packages, the Twin Turbo 600 making 600 HP goes for $27,999 while the 700 HP Twin Turbo kit goes for $54,999. the 700 HP kit can hit 60MPH in a blistering 3.1 seconds and gets to 100 MPH in only 7.5 seconds ultimately hitting the quarter mile in 11.4 seconds at 129MPH.The Ford GT uses twin turbos as well and the kit promises to deliver a tire melting 800HP. With that much power on tap wheel spin is copious to say the least and MT recorded a 0-60 time of 3.4 seconds and the beast hit 150MPH in a mere 12.6 seconds. Imagine that, 150 MPH in the same time it probably takes you family car to hit 60 MPH. Via Motor Trend
