Since there is little after market intake systems, I decided to build my own since just throwing a cone filter in will just absorb heat from around the engine; I tried my best at limiting that.

Parts used was just some scrap sheet metal from work, about 3 feet in total of insulation wrap, paint I had lying around the garage, spray glue I used on another project, and reflective material I used from an old sun visor.

I applaud your ingenuity and craft but by building a box around it again aren't you just better off with the sealed OEM box? I don't see how this can make any more power or prevent heat soak as well as the stock design.

 

[Jwkovach85]

No, it will make a difference. Stock air boxes are extremely restrictive. I’ve seen time and time again actual dyno results regardless of brand where by just having an aftermarket cone filter makes a huge difference especially in Torque.

also bare in mind, the original snorkel from the outside is in place so the filter is still able to pull in outside air.

Also bare in mind, this being a turbo, the air eventually makes its way to the Intercooler after the turbo compresses incoming air which cools it close to ambient before making its way directly to the engine.

So you have either a stock box which has the potential to be be slightly cooler but highly restrictive, or possibly slightly warmer with a set up like this but much much more air; dyno results say bring in the “hot” air.

Great job, some serious skills

I’d like to see the data on the 2.5T SmartStream - the amount/volume of air is electronically controlled, regardless of how restrictive or not, it’s the same volume being ignited.

I plan on putting on the JB4 controller soon which will dramatically change the AFR and IAT. At some point I’ll probably put it on a dyno but what’s nice about the JB4 is you can see all those stats so I will be able to see the difference between stock and with my “intake”

Also, since the 2.5T is shared on other platforms like the K5 and stinger over at Kia, the info you’re talking about is already out there.

I think the original snorkel is not acting much as a vacuum like it would in a closed OEM system. It's possibly more of a ram air effect only. Plus the ecu will compensate and minimize any gain unfortunately.

Ya, the only cold air intake numbers I've seen are for the Stinger 3.3 twin turbo (from KN) - which had a slight increase of 9hp @ close to 6000rpm. This was a dual intake setup... haven't seen any for 2.5T

There has already been many posts about this before, so there is no need to rehash everything before. If you look for the K&N kit that fits the turbo model, it has data from a 21 Kia Sorento 2.5T on it. I would like to see any updated information from K&N on this. http://kandn.com/dynocharts/69-5328_dyno.pdf

Not rehashing anything... I'm genuinely curious when the intake volume of air is controlled by EMU; having a system that is more or less restrictive doesn't change the fact.

I get there is potentially performance (hp) gain with the cold air intake - more molecules of O2 in the cold air intake for the same volume when air is cooled.

OPs engineering is commendable - especially in insulating the heat shield. I've only seen one KN cold air intake, and the heat shield wasn't insulated.

Yeah when I get the JB4 officially on this thing and run some draggy times the logs will give me more answers.

I understand how the ECU ultimately controls things. I’m not disputing that. However, dyno charts don’t lie when it comes to newer cars all with their own ECUs doing the same thing. There IS a measurable increase in HP and especially in TQ.

It isn't a question of volume, it's a question of density. Equal volumes of cold, dense air, and hot, less dense air, contain different quantities of oxygen. Oxygen makes the magic happen!

Also bare in mind, this being a turbo, the air eventually makes its way to the Intercooler after the turbo compresses incoming air which cools it close to ambient before making its way directly to the engine.

That's a big assumption. Especially since the IC on the SC is pretty small, and it's air to air. I doubt it comes close to ambient.

With all that being said, without dyno charts before/after it's all speculation. Personally I won't run K&N on a turbo. You may get a slight increase in power but the reduction in filtering efficiency of a K&N isn't worth the risk IMO.

I hope so. Keep us posted on dyno results please.

When you post your dyno charts we'll know for sure then won't we?

 

[childoffire79]

It needs to be specifically tuned for the air flow of the new filter. Then dyno tested. Before and after would be best. JB4 isn't going to know what that air filter set up is. It's too generic.

Major kudos to @Jwkovach85 for his fab work!

Not to get in to the whole "does a CAIS add hp & tq" discussion, but here are numbers for a 2.5T from AEM (same intake I installed):

Legit or not, I enjoy the sound.

Yep, I installed the K&N into my Stinger and loved it, girlfriend hated it (the whoosh), installing the K&N (69-5328TC) for the Santa Cruz the next few weeks.
