So...I've just picked up my 2010 Tau Sedan w/Tech to use as a template for manufacturing purposes. We'll display it at SEMA next year with our products, but I'm interested in seeing what you're looking for. My considerations so far:

1. Front Grill - I will actually be smoking out the entire front grill similar to a black chrome look. I plan on doing this to my personal vehicle and see how it holds up to the weather. If it holds well, I'll offer this product to the gen pop.

2. Intake - at a glance, I'm not seeing much room for a cold air intake. I'll be diassembling the front and rear bumpers tomorrow, so I'll have a better look as to what's possible. But a short ram is definitely doable.

3. Tuner - I'm talking with Hypertech. They're a bit skeptical since it's a new ECU for them. My hopes is that they'll be able to fix the slow shifting and up the power a bit.

4. Test pipes - funny thing is that these pipes are exactly the same as the V6 coupe. I haven't looked at the V6 sedan yet, but my assumptions are they're the same. I have 6 sets made up already, but I'm waiting on a response from the site admin to setup as an authorized vendor to provide you a price.

5. Exhaust - hopefully, I can come up with an economical exhaust. We'll probably sell it in two separate sections: the axle back and an X pipe so that you can mod at your leisure. We'll most likely offer a discount for a combo package.

6. Power - well...this is our secret project for now since it'll take a long time to develop. But...it involves 2 snails.

7. Cosmetics - still unsure about this here, but I might manufacture carbon fiber covers/replacements for the engine compartment. Don't see a huge market here though, so I might just make ours a one off.

8. Body Kit - our body kit company is sending me a Lexus lip kit for the sedan. I'll be using it as a template to cut/refabricate a lip kit for the Sedans. Look for this hopefully in the fall considering the development and manufacturing time.

Uhm...I think that's about it. Now your turn. I've owned mine for 27 hours now. It didn't last 20 hours before we started tearing into it. LOL.

#3 is pretty much all that I care about. The car with either engine doesn't really lack power, but the shift program is annoying.

 

[wallymn]

1. ECS defeat - no point in having power you can't use...

2. ECU upgrades for throttle response, and shift pattern response.
Since this is a common tranny this might be done by someone already.

I can't see more than this for me. There is a lot of power available which we can't really tap now, I would pay $$$ for a proper shift pattern and more aggressive throttle mapping...

 

[borregoguy]

You might consider expanding your engine products scope to include the Kia Borrego V8 since it is the Tau V8 also. It is tuned for a broader torque curve (for towing) than the Genesis V8. I know that you have more room under the hood of the Borrego to play.

[motorsportsauthority]

Thank you. I'll be contacting my local Kia dealership then.

 

[PINGGOLF]

For me...

A good tune with an ESC defeat (less intrusive than when I pull the ECS fuse. I loose the speedo, nav, and most functions on the center stack)

A good exhaust. I want something just slightly louder than stock. Honestly, I think if I just remove the resonators, that it will sound perfect.

 

[motorsportsauthority]

We'll be working on the exhaust once I free up a lift. I want to clarify and reword that Hypertech isn't "skeptical" about the vehicle. I apologize because that was bad wording on my part. There just unsure about how to go about hacking into the ECU since it's a new system to them.

However, I did get a confirmation that the car is on their list! I will be notified as soon as they are able to get it in for tune.

 

[scotttisha]

shifting at redline with crisper & quicker shifts

ESC defeat (true defeat)

few more ponies unleashed via ecu upgrade.


i don't see a need for a cold air intake...see my thread about intake temps.

I'm late to the party but this is what I want too. I have NO NEED for additional power but want shifting and ESC adjusted.

p.s. My last two vehicles (5.4L Triton and 6.0L Powerstroke) both blew head gaskets after modding the ECU so I have no desire to go through that again.

 

[gcarper]

I am only interested in the Twin Snails (call it the Nautilus Propulsion system)... I would love to have 480 - 500 RWHP on this car. I want the car to be a sleeper - so the supercharger would have to be completely stealth. But you better hurry - Looks like Hyundai is already moving forward...

http://jalopnik.com/5152215/hyundai-shows-off-460-hp-prototype-supercharged-tau-v8

The 4.6 liter Tau V8 offered in the Hyundai Genesis Sedan normally cranks out 380 HP, but this prototype engine gets a screw-type supercharger with a novel clutched pulley, a water-to-air intercooler, and cylinder deactivation. This results in 460 HP and 435 lb-ft of torque while returning 8% better fuel economy.


The flow path is rather unique as well, with the supercharger intake at the rear, charged air going down into the intercooler and then back up into a split plenum which feeds the throttle at the rear of the engine. There aren't any formal plans to introduce this engine to any product at the moment, but it exists, which means there's a gleam in someone's eye. Perhaps sooner or later we'll get to run the Hyundai Genesis R-Spec Sedan versus the Chrysler 300C SRT8.

HYUNDAI TECHNICAL CENTER AND RKSPORT GIVE GENESIS SEDAN ATTITUDE BOOST, EFFICIENCY GAINS AT SEMA SHOW 2008

LAS VEGAS, Nov. 4, 2008 – Hyundai America Technical Center, Inc. (HATCI) and RKSport, Inc. teamed up to develop a customized, high-performance Genesis sedan for the 2008 Specialty Equipment Market Association (SEMA) Show. HATCI contributed a supercharged Tau V8 engine with cylinder deactivation technology that boosts output to 460-horsepower and improves fuel economy by up to 8 percent. RKSport customized the recently launched rear-wheel drive Genesis inside and out to help make it one of the main attractions at Hyundai’s booth in the Las Vegas Convention Center from Nov. 4 – Nov. 7, 2008.
“The 2009 Hyundai Genesis provides us a great opportunity to expand on the overall concepts originally designed by Hyundai engineers,” says Bob Smith, owner, RKSport. “We plan to maximize the performance abilities of the Genesis and are looking forward to developing a must-see car at this year’s SEMA show.”
The RKSport/HATCI Genesis is designed with an understated elegance. The Platinum Silver color scheme highlights the body kit, exterior components, clean lines and contours of the vehicle. Under the skin, the car is powered by Hyundai’s state of the art 4.6-liter Tau engine, which produces 460-horsepower with the help of an IHI screw-type supercharger and 11 pounds of boost for performance driving. The car reaches 60 mph in 4.9 seconds and clicks through the quarter mile gate in 13.58 seconds at 108 mph.
The vehicle also boasts advanced cylinder deactivation technology, which further improves efficiency and fuel savings at cruising speeds. In fact, this Genesis powered by a supercharged Tau delivers an estimated 18 miles per gallon in city and 27 miles per gallon on the highway which match the fuel economy number of the Genesis 3.8-liter V6.
“The Tau is Hyundai’s first-ever V8 engine and it offers great performance characteristics today with even more potential in the future,” says John Juriga, HATCI powertrain director. “The company designed the Tau with future technologies in mind protecting for boosting, direct injection, cylinder deactivation and more. Advanced technology is a cornerstone of our plans to improve efficiency and fuel economy across our lineup.”
Styling modifications to the RKSport/HATCI Genesis include a modified hood, polyurethane front lower fascia, rear lower fascia, left and right side skirts, plus a composite rear roof spoiler and trunk spoiler. RKSport partnered with well-known aftermarket companies to add TSW alloy wheels, a Baer performance brake package, K&N performance air intake, Eibach lowering springs and a Magnaflow performance exhaust.

POWERPLANT
Although Hyundai has not announced any production intentions for a supercharged version of the Tau V8, HATCI is often tasked by the company with special projects. The team at HATCI has been working on combining a boosted Tau with cylinder deactivation for more than a year and was more than happy to supply the powerplant in the RKSport show car.
Hyundai’s reputation for value is based on efficiency in design, engineering and manufacturing that provides value to the customer, so the HATCI team set about their boosted Tau project with the intention of improving overall fuel efficiency and power. They added cylinder deactivation to improve the fuel economy when highway cruising at light pedal inputs. This Tau engine achieves cylinder deactivation on four cylinders through the addition of latching roller finger followers with oil control solenoids, which de-latch at cruising speeds, thus deactivating intake and exhaust valves. The advanced engine control module regulates cylinder deactivation when the vehicle is not in need of eight-cylinder power. But when the hammer is dropped, this Tau takes on a new personality activating all eight cylinders and stirring in 11 pounds of boost courtesy of an IHI supercharger.
HATCI started with a stock Tau 4.6-liter V8 with a goal of improving performance, but maintaining the engine’s inherent durability and efficiency. To help handle the increased power planned for the boosted engine, several key components were optimized. The cracked metal rods are nearly stock, but feature a robust optimized geometry adding mass in high load areas around the pin bore and shank. The pistons also have a unique design and help provide the optimal reduced 9:1 compression ratio, down from the naturally aspirated model’s 10.2:1. The forged crank shaft is stock. Oil squirters were added to cool the undersides of the pistons during operation.
IHI supplied their screw-type supercharger to pump air to the enhanced engine. The “big mouth” intake increases efficiency of air flow through the unit. HATCI mounted the fuel runners directly to the supercharger to improve the packaging efficiency of the unit. This allowed them to maintain injector spacing and orientation. The intercooler mounts beneath the supercharger in the engine’s “V” despite its inherently tight head-to-head width. The throttle body is located after the supercharger with a Y-adapter feeding air to the plenum. This compact design was part of HATCI’s engineering brief – not only to boost the engine, but to do it with practicality and efficiency. Indeed, the tidy engine and blower assembly tuck neatly under a stock Genesis hood.
Adding power under the hood required some additional enhancements throughout the powertrain. The ZF 6-speed automatic, already a world-class transmission, was built to nominal specifications. Detroit Clutch and Gear provided a beefier two-piece drive shaft with larger, reinforced u-joints. HATCI fabricators replaced the stock exhaust system with a 3-inch OD stainless steel system complete with large-port catalytic converters.

HYUNDAI GENESIS
The Genesis sedan is built on Hyundai’s all-new, performance-driven rear-wheel-drive architecture. It offers two powertrains, including a 3.8-liter V6 engine and Hyundai’s all-new 4.6-liter Tau V8. Tau produces 375 horsepower, leading all its competitors in specific output with 80 horsepower per liter while delivering 25 mile per gallon. With technology rivaling more expensive luxury sedans, Genesis showcases features such as XM NavTraffic, ZF six-speed transmission, Adaptive Front Lighting System (AFLS), Smart Cruise Control, Lexicon® audio systems and electronic active head restraints. Additionally, all Hyundai Genesis have standard iPod connectivity.

A supercharger, I'm not worried about. I'll make way more power with our setup.

Everyone's saying ESC delete. I have a ESC on/off button. Do you guys not? I can do a burnout and launch spinning wheels all day when I turn this off.

Everyone's got the button, but the ESC can not be turned off, all the way. You can do burnouts in the V8, not sure about the 6. I think the biggest thing for this car would be an adjustable suspension that is going to clear about 90+% of the gripes about this car.

 

[dataguy]

Perhaps the 2010's ESC OFF is really ESC OFF unlike the 2009?

 

[motorsportsauthority]

Perhaps. Because I can let go of the gas from a burnout and spin through without any decrease in power...leaving a trail. It's definitely nice to see 2.

 

[Kamkaze]

Any more info from hypertech?

 

[Little_Jason]

I know that not to many people would like this but, I really would like to see some sort of bolt on Air suspension kit and also tuning for the ecu

Actually, the ESC can be turned off completely if you pull the fuse.

No. I think they've canned the idea. But I'm trying to get some info from Korea on what they're doing.

The bolt-on air suspension kit won't happen. Just don't see it being cost effective for a company to do the R&D. We can't seem to get anyone to hack into the ECU. SUPER frustrating. I'm hoping I have an inside track in Korea. Hope this lead doesn't go dead.
