How are intakes supposed to increase power in a turbocharged car?

[RM7]

In the case of the Stinger, the intake restriction is the silencer on the front of the core support. Taken off your bumper and looked at that thing? It literally makes several bends, then has a small opening to pull in air from a very small gap (<1/2") between the silencer and the flat plate of the bumper. I swapped to big mouth intakes and there is a significant and noticeable intake pull even when just revving in park. As in this thing pulls more air than my 500 hp v8.

I know the ECU makes its decisions based on a VE table since it only has MAP sensors. I know VE tables are built to represent the total engine dynamics. Change anything and the VE of the engine changes. I'm willing to admit that I do not know all the details of effects on volumetric efficiency. For example, pressure and temp are not the only variables that determine chamber charge. Those variables to not take into account the velocity of the airflow or any pressure waves within the intake track.

If the only way to convince you is independent dyno testing, then put up the cash!

Isn’t the most restrictive part of the “intake path” the tiny intercoooler tubing and associated bends to get there and out? Turbo is a big vacuum cleaner, it’s not going to care within a range how much restriction is upstream of it, it spins because exhaust. Exhaust and wastegate.

New intakes + larger diameter pipes × larger or better flowing intercooler = power gains even without a tune but with a tune much better.

But larger dosnt mean more power. Better heat dispersion is what is important.

Lower IAT's means better ignition timing, and that can count for a lot.
Last summer, I ran several 1/4 mile pulls at Sacramento Raceway at their Wednesday fun drags. First runs during the heat of the afternoon (95+ degrees) were significantly slower due to high IAT's than later in the evening when the ambient air dropped to mid 70's and my IAT's were quite a bit lower (according to the JB4 logs).
This year, I have a bigger intercooler, so hope it helps.

Not to intentionally cost you more money but look for larger diamater hot pipes. The Y pipe that feeds the bov down the front of the engine. Mad ristrictions there.

Ive got mishimoto parts but im sure other companies do the same.

I just bought Velossa tech and using the stock air boxes. way more pull. I see no reason to pair with the "Warm Air Intakes" because I feel the stock airboxes have more suction with the big mouth than intakes thats open to engine.

What really matters is the IAT's AFTER the IC. Thats why "hot air intakes" still make power on turbo cars. The air is super heated running through the turbo anyway. A small amount of cooler air before isnt going to make up the difference that the quantity of air in, that the intakes provide. Best case for total HP is no intake tract, and a filter clamped to turbo inlet. The IC is where you can make some power, lowering IAT's before the throttle body.

Then you need to install one of these.

Ive already put the offer up to do it with my car with a brand new engine, so the offer is out there for @keplaffintech to take up

Hey bro have you got your car back yet from the dealer ? Still wanting to hear some sound clips of your exhaust paired with that ultimate performance downpipe midpipe combo.

Was told by cooperate it would be this Friday at the latest. The amount of times I have heard that already....

Lol I feel your pain. The same with my exhaust and sway bars smh

At this point I dont even remember what its like driving my stinger. just distant memories. I have been reduced to the life of a base model sportage owner

At least they gave you a rental
