    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Alright guys, just installed the K&N referenced above made for the Stinger. For the most part everything makes sense and lines up with the exception of the heat shield. The location of the securing bolt is much lower in the heat shield design than the g80 wheel well. However with the provided rubber support it fits nice and snug under the braces. Additionally you will not believe the sound your turbo spoil will make. It doesn’t feel any different but it sounds like a turboed vehicle now. Under stop and go cruising car remains quiet.
 
Not a big believer of any aftermarket air intake as the computer is what allows much of the airflow into the combustion chamber- NOT the size or construction of the air filter. The sound, however- being open construction, may be louder as pointed out by Shaftdman. Looks cooler too. Worth the $382? Your call.
 
Not really, you need to take some lessons from the hot rodder's, NASCAR boys, NHRA mechanics, etc. This is widely know information for any mechanic, racer or performance enthusiast who has built engines, rather with bolts on's or complete engine assemblies. The ECU controls air/fuel ratios at specific throttle applications, elevations, air densities and more. You have to get more air in, to produce more horsepower and torque out. Larger throttle bodies also provide additional benefits and intake manifolds and headers as well. A larger denser air charge, produces more horsepower. This same application works in Supercharger and Turbochargers as well to produce more power overall.
 
True, but in those circumstances, the ECU is programmed to compensate for those STOCK changes or tuned for the mods. Otherwise put a fan directed into the throttle body. Again- $300-400 for marginal gains.
 
Takes money for horsepower. Without the intake you can do anything you want but it won't see the peak or optimal gains without it. Tuning is only require when you go outside the OEM parameters or wish to gain the full benefits of the bolt-ons. When I say bolt-ons I mean; downpipes, larger intercoolers, CAI Intakes, Piggyback Tuners, bored throttle bodies, headers, and even larger turbos.

With the G70/80 you don't want to do a flash tune. Genesis/Hyundai Service have a flash counter built into their ECU. Get caught flashing the ECU and you can write off the warranty.

However, there's a limit to what the con rods, pistons, bearings and fuel system can absorb. When you get to this point you're asking for engine trouble without internal modifications and improvements. The best two combinations for the money are; the intake and a piggyback tuner. They will give you the biggest bang for your buck, especially in the 3.3T engine. A down pipe and larger air-to-air intercooler are next in line. Methanol or water injection is the last, before you start into the internals of the engine itself.

Any updates? How has it been? Seriously considering this for my sport. Would love to hear your car if you have a video up as well!

Thanks for updating us. I know it's been some months, but I am curious how you substituted the different locations of the bolts to keep the intakes secured. Was the braces you mentioned keeping the rubber support secure all that we (G80 Sport owners) can do, given that the securing bolts don't work?
 
Per the vender (K&N): "Guaranteed to increase horsepower, designed to improve throttle response and engine sound"

Are there any hard numbers to support these claims? Any dyno charts? I had K&N drop filters for my Z and I loved them, so I am happy they are offered for the Genesis/Stinger

Engineering Explained did a comparison with stock, aftermarket and K&N and there was a modest increase.

I love the information you are sharing! I am brand new to tuning... especially in the turbo world, so would appreciate any help.

From the quote above, it looks like you are saying that a Piggyback tune (like the JB4 or RaceChip) plus intake will give you the biggest bang for the buck, but would exhaust also help? Also, from everything I am reading about the piggyback tunes, you really need to change and reap your plugs, but still wondering about exhaust. I don't see you list that at all (though you did mention headers earlier in the same post).

Do you, or anyone else on this forum, know of, or recommend a specific downpipe or intercooler?

I am finding it extremely difficult to find performance parts for the G80, while stuff for the Stinger is all over the place. I just don't know what is interchangeable since they are very familiar, yet not exactly the same in all ways (like the mounting bolts for these K&N heat shields not lining up).
 
Coming from someone who has a heavily modified 350z, getting aftermarket headers, hi-flow cats, and an exhaust will always get you more HP. The issues with exhaust are 1) More sound and 2) More noise. Like seriously, my car is loud AF, the woman hates it

Also, 3) Cost. Good exhausts go for $1200-$2000+. The Return on Investment, from purely a HP perspective, is normally not worth it. You buy it because you want your car to sound bigger and beefier too.

I think headers add about 10HP, hi-flow cats maybe 5, and Exhaust maybe 15, so total for the 3 no more than 40hp maybe at most? This is crank hp, not wheel.

Thanks for this info... I wouldn't mind a little more sound, but I actually prefer how stealthy the car is. It's deceivingly fast like the Tesla because there really isn't too much sound coming out of it.

Still though, with all that said, I am finding it hard to find other performance mods for the G80 besides the simple piggyback tuner and new plugs. I want to upgrade my brakes and would like to do downpipe, air filters and intercooler. Haven't found any of these that specifically say G80... just Stinger.

Thats because of who is buying the genesis. Generally the ages are a bit higher and the need to tune luxury over sport is a bit lower. Granted, we may not be the majority but supply and demand isnt there for the g80 (yet). I have seen about 10 stingers on the road and at shows. A side from my g80 sport, I have only ever seen 1 other on the road in the last year. If I had to guess the guys age, he was well into his 70s and odds were good that he had no intentions on modding the car.

I had to find an exotic car shop to do my exhaust work as it had to be custom welded. No tuners can tune this car either as the ecu wont allow for it (or so im told). They all recommend the JB4 or other piggyback tunes.

Right now its supply and demand. If we had a page with requested mods and numbers for sales, we may be able to get some bigger brand buy in but right now, they wont risk it. Im all in for a full cat-back though if everyone else is. Right now the axle-back sounds nice but I want a better tone.

^^^ Theres alot of truth to this. I bought my Z when I was in my mid 20s and modded the ever living shit out of it. I am now in my mid 30s, about to buy a Stinger GT and start a family, and the amount of mods I want to install is <5. My dad (corvette) doesnt even do his own work anymore on the car and just drops it off at the dealer.

Modding your car is most def a young mans game.
