Power gains based on Mods

[Dr. Shinigami]

Hi there, I know this post is a bit old, but I just signed up as a new member. I'll be picking up my 2019 Stinger GT2 AWD tomorrow , but I've been actively researching mods for weeks now in preparation for my new baby!

2 questions:

#1: I know someone mentioned it wasn't a true CAI. I can't tell from the video, but are they not using the factory ducts to feed air into what appears to be an enclosed heat shield?

#2: Does anyone no how they deleted the orange on the turn signal? Those headlights look amazing without the orange and I'd love to do that to mine! That's the exterior color I bought (with Red interior ), so very excited to pick her up tomorrow.

Thanks in advance!

Welcome aboard and congratulations on the new acquisition.

#1: It is really hard to tell form the video, there are not many photos of that intake either, but from looking at all other intakes available currently for the 3.3 platform, I can tell you that the factory ducts are still in place. However the real benefit is if the heat shield seals or closes directly with it, forcing the air to be sucked directly from the ducts and not form the engine bay.

#2: The headlights on Stinger overseas come like that from factory. The Stinger's for the North american market all have the orange reflector. Yes I agree it looks a lot better in white.

Thank you, glad to be here...finally!

#1: Agreed, I reached out to the manufacturer, because I refuse to purchase an intake that is not both fully shielded and sealed with the factory ducts. No point of drawing in air from the engine bay when there are perfectly good ducts to utilize.

#2: Oh yes, that's the required amber reflector I assume?

have you looked at the JT intake? That one actually modifies the factory ducts and makes it flow even more air directly to the filters. I personally have it on mine and it is great, quality and fitment are great. Very good reviews can be found here as well.

Correct, "required"

I've looked at the JT and they're currently the front-runner on my list, but I'm hesitant on modding the intake duct. How much trimming/cutting is necessary? I've always modded my cars, but I've never owned a brand new car, so I'm a tad hesitant on that (warranty issues scare me).

Is there any rubbing on the hoses? Or rattle between the enclosure and the strut? Do you still get a nice spool sound with the JT? I can't seem to find any sound clips.

 

[robz32]

No issues at all with the JT intake. The cutting/trimming sounds more intimidating than it actually is. No issues with warranty at all. This is also my first brand new car.

No rubbing whatsoever or rattles. There is about a 1/4 to 1/2 inch gap between the enclosures and the strut bars.

Yes, you get LOTS of spooling sounds and blow off, when you put your foot down. It gets addicting very quick

Awesome to hear, thank you!

My previous vehicle was a 2013 Kia Optima SX-L that I chipped and modded the hell out of, but being a brand new car, I'm less inclined to go crazy. That being said, I think JT is going to be my next purchase! I already got badges and front/rear sway bars, and I don't even have the car yet!

hahaaha!!...nice...Make a post once you get it...Congrats again.

The first breather mod (Intake or exhaust) You put on a car will almost always show the highest gains over stock with the rest seeming to get you less and less as you add more mods. You could put the intake on first, dyno it alone then throw on the catback and I'd bet money this post would be full of people saying that the catback doesnt do much instead of the intake. There's a point of diminishing returns from bolt-ons so the first thing you throw in the car will usually have the biggest change with others seeming having less and less effect, regardless of the order you install them.

If you watch the video, they actually tested just the intakes alone and the result was the same.

Intake alone = 2rKw
Intake on top of exhaust = 3rKw

I'll make a separate, newbie, intro post hopefully tomorrow, but finally got this purdy gal home tonight. 2019 GT2 AWD.

I got to drive her off the showroom floor with 23 miles on the ody, so I'm being THAT guy and keeping within the manual recommended 2k-4k RPM band until 600 miles.

That being said, the 4 hour, 2x mountain pass drive home was significantly more enjoyable than the 6 hour drive there with a 10' box truck and '13 Optima SX-L being towed on a flatbed (I loved that car).

Thanks again for the welcomes and replies, looking forward to contributing to the community.

Time to glamify this stunner by putting on some makeup, shaving her legs and tightening up that a$$... By that I mean remove those horrendous KIA badges and slap on some sway bars!

Interesting. My previous SX-L reaped the benefits of each new mod and the butt Dyno seemed to agree. Freeing up the lungs added some nice throttle response. Opening up the bowels, turbo back, generated very notable mid- and top-end performance. Fine-tuning her brain integrated both and turned her into a "beast."

I'm very interested in butt dyno-ing each and every change I make on the Stinger. Diminishing returns vs. anticipated expectations... Should be fun!

The dyno numbers are killing me. I'm finding negligible to significant gains on either intake or turbo back, yet minor gains over one or the other when combined.

Maybe I haven't done enough research, but this doesn't seem to add up. Granted only poked around for a couple of weeks, but I'm patiently waiting to purchase any intake- or exhaust-side mods until I have more information. Again, maybe it's there and I just have done the due diligence to find it.

Anyways, blah, blah, blah, here she is!

On the showroom floor and after I drove her out (boring for you guys, but I'm stoked!).

How come gains from the chip is so small?
It should be from 60 to 100 hp only with a chip.

Not sure about the Stinger yet, but on my Optima, the chip was ~40 hp and was fantastic (LAP3). I took it off one time after having it on for several months and realized just how much it did for that car.

Didn't say you won't notice it and tuning will absolutely bring it all together for the biggest gains. It's a lot more noticeable on a N/A car than a factory turbo'ed car because turbo cars respond better to mods in general but there comes a point where putting on every bolt-on available will start to net you less and less gain..at least until you tune for them. And more often than not they'll help support bigger mods like turbo upgrades.

I think there's a couple things going on. Number one, with the stock turbo the peak hp is around 5 to 5.5k rpm, and the stock intake doesn't start to choke the power until after that point. So while on paper the intake mod might not look like it adds a ton of power, it adds the most at the very end of the rpm band, which will actually still help the car pull to redline. (Note all the intake sellers are advertising their maximum hp gains, not gains at peak hp).

Secondly, there definitely is a form of diminishing returns with bolt ons on the stock turbos, even with a tune. They are tiny and if you open them up enough to breathe sufficiently, then the rest of the mods kind of end up as stored potential.

And lastly, it appears that the most significant breathing restriction is the stock cat/downpipe (primary). If that is removed, it appears that really everything else is overkill except maybe just drop in filters, because the turbos are then able to flow at full capacity. This kind of is just a spin off of what was stated above about dimishing returns, but to summarize, your best bang for your buck will be to free up the exhaust as close to the turbos as possible. The rest will be potential for alternate fueling or bigger turbos.

I recently purchased a 2021 kia stinger gt2
I have a full exhaust, enjen cold air intake, gts black chip and better spark plugs. Would love to know what the hp is. But honestly it's pretty damn fast

Dyno it.
