As it says 3.4 whipple purchased from lethal. 3500 shipped to your door or picked up locally plus !!paypal fees!!. I have seen 730hp/754tq with 25 pounds of boost 17* timing on 93 octane on a street/race tune. This car has never been down the track, and is driven 15 miles per week to school. Im want to sell this blower but am NOT desperate so no low ballers please I feel the price is fair for a blower with less than 300 miles. Blower comes with factory warrenty from whipple.
