I purchased the Turbinator for my 2005 Crown Vic. The Engine is a 4.6 2V. The device is supposed to increase HP and fuel mileage about 10%. I paid about 70 bucks for it. It installs in the throttle body quite easily. No other modifications are needed. Upon driving, I noticed the car ran the same. When flooring it, the engine loses power and just plain dies.When raising my foot off the pedal, the engine speeds up. I didnt really notice an increase in fuel economy so I just removed it. I began flooring the engine and it ran like normal again. Bottom line, it starved the engine of air. Maybe upgrading the air system would make it more effective.
