is it possiable to supercharge a crown vic's 4.6 and if so where could i find one for it and not spend a boat load of money all replies are greatly respected

 

Hi and welcome to Ford TRUCK Enthusiasts

It's possible. Take a look at http://www.crownvic.net/ubbthreads/index.php
I just did a quick search there and found some info.
Have fun

 

go to www.CrownVicMuscle.com and www.alternativeauto.com
Good stuff there!

 

Wouldn't such a thing be the Mercury Marauder? Or am I mistaken?

 

Vortech makes a kit for it. It requires that the alternator be turned backwards. Looks kind of weird.

 

Isn't that the same engine as the mustang? It was supercharged, check Ford Racing

 

The Marauder is a de-tuned Cobra motor (4v), but not supercharged. I assume you could do it with any blower made for the 4.6 (lots) but then again I know nothing about Crown Vics.

 

I wonder if you can swap a supercharger out of the new cobra 4.6 liters. If it is a 4.6 I dont see why not.

 

The Marauder as a concept car was supposed to have a super charger but in production it was just a Cobra(detuned?) motor. I think they planned to use a Whipple or Roots type blower.

The 4.6 can be supercharged, Car and Driver did a flog several years ago where they did just that. This probably helped push Ford on the Marauder concept. Unfortunately, I think C&D blew up 2 or three motors getting it right.

I think the Lightning is a 4.6 with supercharger(Roots/Whipple I think). If so, then it can be done commercially and there might be junk yard motors around(I bet at a premium).

The main thing with supercharging stock motors like the 4.6, so I have read, is to be conservative, you don't want to melt things or detonate it to pieces. The chebby group I belong with did a LOT of supercharging(mostly Paxton type, some Roots/whipple and some turbo) experiments with the LT1 and discovered early on that the factory pistons(hypereutectic, I think Ford uses these too) would melt if you got too aggressive with the boost. If you want a lot of power you will need to beef up the innards if you want to live. Stay conservative and you will have plenty of fun for "reasonable" cost.

Good Luck,

The air inlet is on different sides. In Mustangs, the air filter/box/tube is on the passenger side. On Crown Vics, the air filter/box/tube is on the driver side. Not even the throttle bodies will swap without modification to the linkage.
