Forced induction on a 04-08 5.4 4WD SCrew? Thoughts?
 

Was getting the itch, looking for thoughts from community, people with hands-on long-term knowledge of the specific Edelbrock E-force kit preferred, but will take any thoughts/advice I can get from people who have gone the FI route with their trucks.

Ability of truck overall to handle the added power (not looking to stomp on it from light to light, nor track it, just looking for a bit more get-up-and-go out of the sluggish SuperCrew monster I have. Already did a pulleys, intake, headers, and tune setup, now looking for more out of it).

Bottom end, tranny, driveline in general, can it all take the added kit Edelbrock offers? From what I've read "yes", but would like some hands-on knowledge from people that have added forced induction.

Thanks in advance for dealing with my n00b-ness in the FI field and any advice you can give.

I been down this path (owned three 5.4's) in which not enough power.

cost to use upgrades to the 5.4 and or install 4.11 rear was not attractive rlative to the new net result and the future value of the vehicle.

ultimately when to v-10 with 4.11 which was a big improvement but still not the final solution.

currently on 6.4 diesel with meth injection. The rear is 4.33.

Thanks for the reply. Have you ever done the supercharger method? That's more specifically what I am looking to hear about here.

Not interested in "cost isn't worth it with value of truck". The ~$6k figure (plus another ~$1.5k to install it if I don't do it myself) seems reasonable for the 478rwhp the kit claims to give.

I'm more looking at what else am I going to have to upgrade/replace over time with the additional power? Again, not looking to stomp on it as though every redlight is a race, but I would like the truck to move when I want it to (getting on highway, etc.)

And of course I'd like to hear stories from people that have supercharged (or any type of forced induction setup) their trucks and the short and long term affects of it, both positive and negative.

Thanks!

Now you can bolt-on an Edelbrock E-Force Supercharger system and boost the power in your Ford F-150. These E-Force Supercharger systems are specially designed for each application and will allow you to boost your performance up to an impressive 478 flywheel horsepower and 504 ft-lbs. of torque. These systems feature 14" long intake runners for maximum low end torque making them ideal for towing and off-road performance applications.

I guess in my opinion it boils down to how you will use the truck.

For a towing application I would not opt for a twin screw. A turbo with a large intercooler would work better. Heatsoak with twin screws is an issue no matter what you do.

For hot rodding like a light mustang stop light to stop light or 5 or 10 seconds at WOT than the twinscrew would be better.

I have a 10 psi KB kit on my V10 and have to use water meth to cool boost above 5 psi.

IAT are above 200 degrees at wot. Granted the water intercooler on a edelbrock will help but for long boost times the water will get hot unless you have a huge heat exchanger. The twin screws make alot of heat that the case absorbs.

KB never sold a supercharger kit for the 2004-2008 F150 5.4l 3v. I have been supercharged since 2006 and have towed and hauled my toys since day one with no problems.

Interesting.

I am really intrested in the fueling and timing logic that is used.

My setup will boost to 7 or 8 psi in closed loop while towing, partial throttle. I use methanol at about 4 psi and up to prevent detination.

How does edelbrock deal with high compression/boost while in closed loop at low rpms?

With mine I can hit 7 psi at 2200 rpms if I tow a heavy load and pcm is in closed loop with an AFR of 14.5 to 14.9.

​

Your set up is not the same as mine or the edelbrock in question

Agree,

I guess the best advise I can give is to make sure the Edelbrock system has a large heat exchanger and plenty of water to keep things cool, if planning on towing. A 5 min pull up a hill at 5 psi boost will put a pretty good load on the water to air intercooler.

If not much towing than it is not a huge issue.

I'm really not a huge fan of a 2.3L supercharger for my V10. It's not bad for a 5.4 motor. EdelbrockS SC is 2.3 L so it will work ok, but I woud opt for a larger unit to help reduce heat if possible.

What type is your supercharger?

After re-reading the OP, I don't think towing is an issue.

But I will tell you that a SC will not add any get up and go to normal everyday light throttle driving.

Maybe merging onto an interstate will improve slightly.....Probably hit 3 or 4 psi boost. Hills will seem easier to pull as you will hit maybe 3 or 4 psi on a big one. Passing on a 2 lane road will be greatly improved.

Normal stop and go traffic will not be changed.

I have a tiny Powerworks Magnacharger.

I hope the OP does not listen to you.

Why?

Could you give an explanation?

He asked for people with long term first hand experience supercharging. You dont have that but many of us do.

Funny,

Bypass Valve is all I have left to say.

Boost happens when vacuum shuts the valve not before. Long term experence obviously doesn't mean knowedgable.
