Intake noises - anything to be gained?

[Chops]

The smallest area for air to flow thru on EBs is the turbo inlet, that is the restriction and unless you change that size it remains the limit of total air flow.

Isn’t the smallest area for air to flow found in the airbox filter or fins in the intercooler? The inlet to the turbo seems unrestricted?

OEM's do not publicly share that data. When all the OEM's are searching for fractional CAFE improvements, why would you assume the intake system is a restriction?

All you have to do is find dyno data that shows some spec improvement with nothing more than an aftermarket intake. There's a reason that data doesn't exist.

I'm not making any assumptions. I have not stated or implied that the factory intake is a restriction, and honestly I don't believe that it is. Are you saying that there can absolutely can be no improvements to the factory intake? That is what I consider an assumption unless you have supporting data.

There are no meaningful restrictions to the OEM system. As is, it is capable of efficient performance to at least +50% of the current rated 2.0EB specs.

You've presented this as truth, not opinion. Where is the supporting data?

The air filter & airbox is THE biggest restriction on OEM air flow. Keeping the intake air clean is a necessary “evil”.

I’d guess the second biggest restriction is the intercooler? Lowering the intake temperature is beneficial however.

Installing the 300T “Big Turbo” will give +50hp per Ford…

What is the source of your +50% statistic?

This is common margin for many types of OEM performance tests.

I have 40+ years in automotive, from dealer-level, to professional NHRA race team, and 25 years in product development for an OEM. I'm just trying to be helpful. You can choose to believe whatever you wish.

Biggest restriction to what? Are you trying to make 600HP?

It's not a "restriction" until it keeps something intended from happening.

Thanks. I'll choose to believe any data provided. But I won't choose to believe your opinion even if you present it as fact.

Biggest restriction to air flow. The main gist of this thread on aftermarket air intakes…

Well, you are incorrect, but ok...

Yes, aftermarket intakes.... it's your money, spend it as you wish...

Like I said before - I’m installing an aftermarket airbox for the sound.

Of course I’m depending on S&B to offer proper filtration. They spend time perfecting that vs dyno testing - which is good imo.

Some folks upgrade the stereo in their Mavericks for better sound. I did that too when I was younger…

And thank you for giving me permission to spend my money as I want

The 2 turbo inlets on my 2.7 are 34mm 1.3 inch in diameter each. The 2.0 EB is 57mm 2.25 inches.
But the whole efficiency argument is intake flow only. No consideration of how much air can the engine use, this is why I keep bringing up the tune because that is what determines the amount of air and fuel needed to reach the programed limit set by the ECU. Electronically tuned engines are software based not hardware. KM

Although you have a twin turbo lucky!

Yup but even then it is like breathing thru a frame of a pair of glasses. Still the tuned 2.7 easily made 450 HP and more torque after tuning. All thanks to those tiny snails pumping hard.

Are you on E85?

 

[F150 2.7 TT user]

No, travel long road trips so I use an adjustable octane performance tune from Gearhead. Anything from 87 to 93+ works but mileage and performance are best with 93 octane 10% ethanol common local mix. Odd combo a light RCSB 2wd 3.73 gear, leveled on large 285-70-17s. Best mileage is the home 93 blend at 27 highway mileage, 87 drops near 6 MPG and is close to the cost of the 93 I use at home. Fun thing with my setup is the responsiveness. The snail pump so fast that LAG is near undetectable, this required learning a new driving style to keep the back end in line! I drag raced a street stock 1968 Z28 in the 70's (low 13 second ETs), my F150 is quicker!

Was the downpipe like $1,200 dollars?

He paid right around $1500 shipped.
