WANTED: More HP in a 5.4L 2002

[Alex Paterson]

Anyone out there know what can be done with a 2002 Ford F150 5.4L V8 to give it some more get up and go. I am trying to find ways other then a super charger or turbo and reliability is a big deal for me. I would like to have somewhere around 450-500hp. Any thoughts or suggestions?

Thanks,
Alex

I believe that motor is making around 300 stock. 150 plus, over that without a turbo or supercharger would require some serious engine work. I am sure it can be done without exceeding 10 to 1 compression (race fuel needed) but you're talking about a race motor at that point. The common bolt-ons, headers and exhuast, intake and a chip might get you near 80 or maybe 90hp more. *disclaimer (Those are manufactures' numbers.) This is just my opinion based on limmited knoledge!

Thanks for the help. Kenne Bell makes a super charger good for about 415-450 hp, but I am trying to stay away froma blower but that may be the best route, short of calling Patton I have read that headers really do nothing for this engine and I am running an K&N based intake but actually want to go back to stock or a UPM style filter system. I will try a programmer before I do anything major to see how that helps.

This sports funny, you make one thing better and it opens up four other issues.

The 5.4L is not a very big V8, only 330 or so cubic inches. Trying to get 450-500 hp from 330ci (with no boost) is going to require more money than you'll ever want to spend. In my opinion you've got three realistic choices... boost from either a turbo or supercharger, spend crazy amounts of $$$, run a different motor. Only one obvious solution is coming to mind.... BOOST!

Look at a Leon Patton motor... $35,000 and 442ci gets you 750hp. Sure, it's a full blown race motor, but you get the idea of the $$$ involved to get big reliable power from a small V8. The 5.4L is the base motor for the Ford GT-40... running a blower and it's making 500+ reliable hp. The price tag will make you cringe.

You can get a 500-550 horsepower 4 valve 5.4 motor with an aviaid dry sump system for $11,000 from I guy in Florida that builds them. BOSS330.com I think? Contact me if you are serious adn I will put you in contact with the guy.

There is a stroker kit that will bump it up to a 5.7. I think its a svo thing. And dry sumping is required too. The upper limit for that engine is 550 naturally asperated. Oh ya, I dont think a factory FI or any of the factory intake stuff will support that hp either.

It would get spendy buy the time it was done. To give you an idea of how much, go to you local dealer and price a gt40 creat engine.

Thanks for the info guys, I think I could get a little over my head. The other issue is keeping it SMOG legal for AZ. I will do some more research, the other problem I am finding is the Superchagers that I like are no longer made for the F150, Whipple and Kenne Bell. The Prochager, Paxton etc take up a ton of room under the hood with plumping and brackets.

This would be bitchen, but at $36,000 I may have to wait a bit.

Hi, Here in Australia Ford are producing quad cam version of the 5.4L. It's effectively the 5.4L bottom end & 4.6L cobra heads. I am not sure if they are getting away with using the 4.6 intake. They are making 320KW (428BHP) with better headers & intakes guys getting up around 330 - 340KW. You should be able to get all the parts very easily over there in the US. You will need to run 98 octane fuel as I don't think they are relieving the heads at all.

Good luck.

If you are serious. You have to call and talk to him. His website is "weak". He was very informative and nice.
