What is the horsepower of a 4.6 liter v8 engine?

Answer 1

Horsepower is actually 161 at the rear wheels for my 1999 2 valve 4.6L Crown Vic, after performing 13 dyno pulls 2 years ago. The crankshaft horsepower of 225 hp loses 29% of its power through the driveline, resulting in 161hp, or 71%. I added an aluminum (police model) driveshaft to dramatically cut down on driveline weight. You may have to add a driveshaft spacer, or longer police model tailshaft (12") to make up for the shorter (5/8") aluminum shaft. The police cars have the higher flowing (Ford Mustang) heads, allowing them to chase you down easier, provided they opt out of using a police radio to send another car after you. The lower horsepower helps with improved fuel mileage, and I have average'd 18-19mpg over the past 9 years. I've only achieved 22-24 mpg a few times on long road trips involving lots of miles. Do your part and write/e-mail FordMoCo to build the Interceptor concept into reality, if you like your Crown Vic/Marquis.
