Easy HP Upgrade - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hey everyone, I am new to this site but I just bought a 2004 Crown LX and I love it. I know there are some good HP upgrades out there for this car but I am trying to keep a budget on it so I was hoping for some good advice that people may have tried. I saw on Edmunds.com that some one said there is an easy way to take the car to 300 HP but I haven't seen anything like that yet! I have the single exhaust now so I know that will need to go to dual but what else???

Thanks in advance for your help.

Well first you will want to get a good dual exhaust system that will free up at least 10+HP, Then a good cold air intake will give you a little more power and work very well with the dual exhaust possible 5+Hp with CAI. Then if you want you can buy a performance chip for the car which will give you about 15+ but they can be quite expensive depending whcih one you go with. Other than the first two you are going to be looking into a whole lot of money on other things to boost up HP.

When reading the feedback on Edmunds.com the person made it seem sooooo easy to get 300hp out of the car. Maybe easy and inexpensive are two different things?

Thanks for the help, anyone else have any ideas or suggestions?

EASY is right....cheap NO WAY. You can get 500 hp with just a few bolt on parts and some computer mods along with a few other minor things,but cheap,not a chance.

Question on dual exhaust. Out here in California, where they don't like you to do anything that might change your emissions output, changing to dual exhaust might be illegal. any thoughts on this? I would like to convert my '05 Vic but would I have to put another cat on it??

'05 Vic, You already Have 2 or 4 cats on the car now so you do not need to put anymore cats on the car. And as for the dual exhaust I would talk to the person you get your E test done and see what he has to say. Plus all a dual exhaust will do for you is make it a little bit louder depending on the mufflers you use, and give you some more HP, as for the emission output it really should not effect it that much.

Thanks for the response amo. I will look into the legalities of changing over.

Ford makes a Dual Exhaust system for the Crown Vic, how hard would it be to take off the Single Exhaust, and replace it with the Ford Dual Exhaust? I am sure they do make one, as Dual Exhaust is an option on Crown Vics.
