Performance bolt on headers group buy

Count me in if you do decide to make a set, although I may try to find a shop build headers this summer if finances permit me to.
 
Having custom made headers made for my R-spec. There will be no converters and the BTR tune allows me to tune it as such, should be interesting. Will let you know how it goes. The car is off the road for winter and is being used as a guinea pig. Happy New Year!!

Sooooo... any updates?
 
I'm glad that you're doing this I have a 2012 I want headers , exhaust manifold for twin turbos under the car or a bracket for a supercharger. I'd be happy to donate money, I don't have much, but I'm sure every little bit helps. Please keep me posted on your progress, I hope you start a trend that blows up to be very profitable for you and your family. God bless you.
 
You're absolutely right. I should have re-worded my post. However, Hyundai didn't exactly drop the mic in regard to marketing the
V-8 cars.
They took a great car with super potential and when they dropped in the 5.0, they aimed it at the wrong market base. While trying to attract the grey-hairs in the near-luxury segment with it's E-Class looks and features, they failed to capitalize on it's abilities as a legitimate performance sedan. You don't put a 400+hp V-8 in a car unless you're trying to make a statement. However, their plan took a steaming dump just like Chevy's did when brought in the SS as the next replacement for the G8.
They totally did. They also went wrong from the factory by keeping it conserved so that it could maintain the 10/100k warranty without costing Hyundai crazy money. They made the ECU near impossible to crack so it couldn't be tuned as well. Luckily BTR's Korean tuners were able to figure out a way but its super inconvenient. If you add mods you have to uninstall the ECU send it back to korea and have them reflash it then send it back which could take up to 2 months with international shipping.... I have everything I can modded on mine so far and then I got the tune but a lot of my mods are custom as that's the only way. My cold air intake is a custom setup consisting of removing the magnetic air flap under the filter, dropping in a K&N panel filter, and having a local fab shop weld together 4" aluminum tubing to fit and wrapped it in gold foil heat deflection wrap. I'm also considering hollowing out the factory airbox. The reason I did this instead of purchasing an R2C or Abel racing was because the factory airbox has proven to be excellent at reducing heatsoak (you can take the lid off and feel the filter and its barely warm after a hard drive) and I like the way it intakes cool air from the grill and directs it to the intake. When you get the aftermarket intakes for the genesis you have a few options. You get the R2C which is discontinued and from a shady company so good luck finding one. A lot of people on here say they have a lot of heatsoak though. Then you could go for the abel racing one but that's a hot air intake cause it doesn't even have a heatshield so all you will do is suck up extremely hot under-hood air and probably reduce performance. The weapon R is small and just a cheaply made company so I wouldn't even consider that crap. So I had a custom one made since I couldn't find one I liked. Same with the exhaust. Not big on how quiet the magnaflow is so I had a fully custom 3" straight pipe done from my cat deletes back with an x pipe in the center. The sound is absolutely amazing and unmatched. They made this car SO QUIET from the factory that I couldn't stand it. Such a beast of a motor has to be unleased.

Adding headers to this setup would be the icing on the cake, so with that said I'm absolutely interested but the cost would have to be around $1k to 1.2k tops for me to retain interest. The gains would be so minimal I just couldn't justify paying more than that. Love the idea but like supercharger and turbo for this car we just need to accept it will never happen. Now I'm not sure if even possible but a set of cams would be insane for this car but I haven't seen anyone mentioning them so those probably wont happen either.

Had me all the way until you mentioned price. Given zero aftermarket support this will most likely be done by a small niche company. Sadly $1k header will probably never happen given design and tooling costs. I would expect $2k at a minimum.

I just cant justify paying 2 grand for maybe 20whp gain... you will probably barely feel that even with a butt dyno

I actually have the discontinue abel racing intake works great and is setup different than the rc2 filter location it doesn't go as deep into the engine bay as the rc2 , the rc2 is a horrible design just a noise maker. The abel racing on the other hand still utilize the stock grill duct due to the length of the tube and there is a actual dyno stock and with the intake on.
Stock 342whp 320wtq
Abel intake 354whp 328wtq

Yes when they dyno the car they leave the hood open with a giant fan blasting cool air into the intake. That doesn't simulate real driving conditions correctly. You drive with the hood closed and all the heat gets sucked into the intake without a proper heat shield setup. I've seen the Abel racing intake and it is an 'open air' intake. Maybe it uses the lower portion of the OEM airbox to help push a little air towards the filter from outside, at the end of the day the heat under the hood is gonna overpower that tiny bit of cold air through the duct and you'll essentially still be heat soaking your engine. For their to be no heatsoak (especially with these engines, they get HOT) the filter would have to be completed isolated from the rest of the engine with some kind of heat shield that remains air tight when the hood is closed, and a source of cool air directed towards the filter inside of that isolated area. That is the only way you will see gains from an air intake under real driving conditions and also why I kept my stock airbox setup and just dropped a k&n filter in there and had a shop custom make me an intake tube without all the power restricting baffles.

what there simulating is the vehicle moving and when the front duct its modified directed at the filter i dont see how its not getting air. when the air goes through the grill duct as your moving it pushes out all warm/hot air thats why you see the bottom of windshield fog its due to that air being pushed out of your engine bay thats one of the benfits when running the air duct open. the rc2 is a different story the location of the filter yes there is no breathing room with the location and with that shield doesnt help.
btw happy for you that you found something that works for you good job. thumbs way up!

That air duct only works when its isolated to a vacuum-like state where the suction produced by the engine is able to pull that fresh air up through the filter and then into the intake manifold. Without that vacuum-like enclosed box or heat shield, the intake will suck up about 10% cool air from outside and 90% warm engine air. The reason the duct works from the factory us because the air travels from the grille through the duct and the filter pulls it directly up cause that air has nowhere to escape to except into the engine. When you leave an open filter on it, it sucks up whatever it sucks up and often times that is nothing but warm air. Google "hot air intake" for more. The duct is designed to work with the factory airbox. It is basically moot if you are using an open air filter.

great info, but sorry im not a big believer of all the info on google , last time i googled and tried to diagnose my illness google told me i was going to die.

The fan isn't there to simulate driving conditions, it's there for one job - to keep the engine from overheating during multiple redline and high RPM dyno pulls. If the car is not moving and letting air pass through the radiator, the car will just get hotter and hotter if the fan isn't there. If you want an accurate dyno, close the hood and dyno it that way in the same weather conditions before the intake and after. But no reputable dyno shop will allow that because of the risk of overheating the engine is too much liability.

I have a SXTH intake on my 4.6 and i can log intake air temps being only 4-7 degrees above ambient temp while driving. A stock air box with factory ducting probably cant do much better then that

All I'm saying is that I've opened my hood over an hour after driving this car and it still blasts me with hot air even after wind and cooling for an hour so I can only imagine what the intake is sucking in.

On my application, I've also wrapped the tubing with the gold heat deflecting wrap which keeps the temp around 10 degrees cooler as well.
