06 Expedition 5.4 performance Intake Maifold

[AbelNavyvet]

Does anyone know if anyone makes a performance aftermarket Intake manifold? I tried edelbrock I tried FAST and Holley but no one seems to make it. is this true? I seem Dorman but I never heard of them... what about an aftermarket throttle body? any one know if they are available?
Please Help!!!

BBK has an 80mm throttle body

I know a guy that swapped a 5.4 into his Mustang with that intake. It had tons of torque but was done by 5500rpm. And it only works on 2v heads. 06 has the 3v. That's why I suggested the E Force in the other thread. It replaces the entire intake.

So I talked to HPS in El Paso TX and Mr. Brown does not make those manifolds any more. and according to HPS there is no one that makes performance intake Manifolds for 2nd Gen Expeditions....

That throttle body by BBK looks awesome Jdecker.... for 7-14 Hps I Think i'm going to get it...

Bigger throttle body is going to be a waste of money on stock manifold.
Don't do it. You'll never see that 7 HP gain without a re - tune
that will switch you to high test. And then I'd be suprised if you even see 3.

so in order to feel the HPs from that throttle body I need a tune?

 

[AbelNavyvet]

Which type of tune is better Laptop or handheld tune like SCT or superchips?

im willing to bet laptop

The best way to tune is either just use the canned tunes from the programer or take it to a dyno and actualy do a real tune based dyno results.

should I finish building her then take her to a dyno?

You need a bigger engine to feel the benefits. 7hp is small enough to be considered a variance in the dyno itself. The stock throttle body flows enough air for a stock engine. The only reason everyone talks about increased throttle response is because the bigger throttle body allows more air in at less throttle angle. But at WOT there is no difference. If the stock engine only needs 700cfm and the stock throttle body flows 750cfm, then it's not a restriction. You can put a throttle body capable of flowing 1000cfm on there. The engine will still only need and use 700cfm.

The best tune is the one you do yourself. No tuner will spend the time and care as much about your car as you do. Plus if you have the software you can make adjustments as needed. You won't have to pay a tuner each time. Get everything worked out then figure out the tune.
