Ahh, yeah, i was going to mention, that thing looks thin, but it probably helps to "aim" the exhaust gasses toward the turbo.

Re: 4b11t going into new RWD Hyundai coupe
 

They're here!





My girl at Walser Hyundai called me and said she got to drive the 1st one in. A leathered out 6cyl A/T.

It's the only one they got so far but should have more this week.

Re: 4b11t going into new RWD Hyundai coupe
 

Nice! What sucks though is that I've been hearing that the 2.0's are gonna be delayed till mid March. How did she like it?

Re: 4b11t going into new RWD Hyundai coupe
 

Gives you time to save for that down payment.

Re: 4b11t going into new RWD Hyundai coupe
 

Dealers across the country have all got V6 Auto's, no 2.0T's yet. No solid info on delivery dates either.

We've already tested the 2010 Hyundai Genesis Coupe, but enthusiasts keen on exploring every facet of its performance credentials now have another data point to consider--our chassis dyno result.

Hyundai pegs its brand-spankin' new Genesis Coupe's 3.8-liter V6 at 306-hp and 266 lb-ft of torque. To detemine just how truthful they've been in this rating, we strapped a Genesis to the Dynojet rollers at MD Automotive's facility in Westminster, CA, and let 'er rip.
Click for a larger image. And forgive the little gap in the data at 5300 rpm--our speed pick-up momentarily lost its tach signal.

Overall, this result by the Genesis coupe indicates that the V6 version is generating the full output claimed by Hyundai. Of note in particular is the character of the torque curve--flat's the word.

Remember, don't go comparing results across dyno manufacturers because the planet will tilt off-axis and we'll all freeze to death. Feel free to pontificate how the Genesis compares to the BMW 335i and Infiniti G37 we measured a while back, though--we used the same dyno for all three.

Re: 4b11t going into new RWD Hyundai coupe
 

Nonsense! Hyundai must be retarded:

"But we do know that there's a torque-reduction feature on this car that would suck some of the fun out of Conrod Straight. Accelerate hard in 1st gear and then do a hard upshift to 2nd at or just before the marked 6,500-rpm redline. You'll get your upshift, but as the revs drop back, you'll feel an additional, artificial cut in power. It lasts for about 3 seconds.

Hyundai says this is a drivetrain protection measure that's triggered at 6,800 rpm (the engine's true redline). However, the car's tachometer lags behind actual engine rpm, so it takes trial and error to find a shift point that keeps you out of the protection zone. Oddly enough, you don't get any intervention until you actually complete your upshift — you can ride the engine to the rev limiter with impunity.

"There's some talk about minimizing the delay, so that it's maybe just a second, but nothing has been signed off," Miles Johnson, Hyundai communications manager, tells us. "The car is going to market with the 3-second calibration."

Even a 1-second delay compromises acceleration, though. Moreover, the automatic torque reduction makes it difficult to get a smooth gearchange at even two-thirds throttle, as it exacerbates the drivetrain lash already present due to the Genesis coupe's soft engine mounts."

Re: 4b11t going into new RWD Hyundai coupe
 

Ghey. I'm sure a little ecuflash hacking will fix that :)

Re: 4b11t going into new RWD Hyundai coupe
 

I hope so; a 3-second lag defeats the purpose of buying a sports car.

Re: 4b11t going into new RWD Hyundai coupe
 

Buying an automatic defeats the purpose of buying a sports car.;)

But like mentioned, I'm sure everything will be hacked once people start getting their hands on the electronics. Then everyone can start busting automatic transmissions.

Re: 4b11t going into new RWD Hyundai coupe
 

This is on the manual transmissions.

Re: 4b11t going into new RWD Hyundai coupe
 

"Forgive our graph, we momentarily lost the tach reading"

Give me a break. Do another run to get a good clean graph. What a bunch of pussies.

Re: 4b11t going into new RWD Hyundai coupe
 

Or at least go into MSpaint and connect the lines

Re: 4b11t going into new RWD Hyundai coupe
 

haha :)

Re: 4b11t going into new RWD Hyundai coupe
 

Especially since that isn't the real dyno sheet anyways.

Re: 4b11t going into new RWD Hyundai coupe
 

WTF! I hope an AEM FI/C or EMS will take care of that. It is unacceptable.


Is this only on the V6? Either way, it is a few hundred rpm past the marked "redline", so I guess it isn't that big of an issue until you want to rev it out a bit(build the head). By that time, some sort of solution will be had I'm sure.

Re: 4b11t going into new RWD Hyundai coupe
 

From what I've heard they used an ecu similar to the EvoX, so it shouldn't be too hard to crack and get rid of that stupid torque limiting thing.

Re: 4b11t going into new RWD Hyundai coupe
 

The Evo X ECU has some very annoying airflow limiting tables. It compares TPS to RPM and if the current airflow isn't close to whats in the airflow tables, then the car goes into limp mode.

Re: 4b11t going into new RWD Hyundai coupe
 

neat.

Re: 4b11t going into new RWD Hyundai coupe
 

Pretty cool! Sweet that it has a timing chain, timing belts ftl.

Re: 4b11t going into new RWD Hyundai coupe
 

I see mivec sections of those cams, that's a plus! Still, there are obvious differences between this and the evo/ralliart motor. Time will tell.

Re: 4b11t going into new RWD Hyundai coupe
 

Well the maybe a shop with money could do an evo X swap!

Re: 4b11t going into new RWD Hyundai coupe
 

The guts of that engine just look poopy. The good thing is it will have millions of suppliers for aftermarket parts, and Since it's a world motor, I bet there's a stroker crank out there somewhere for it. :) Looks like a lot of meat around the ports on that head.

Re: 4b11t going into new RWD Hyundai coupe
 

From what I've gathered it's basically the same basic motor as a Caliber SRT4, and those are 2.4 liter. so I'm sure that crank would drop right in.

Re: 4b11t going into new RWD Hyundai coupe
 

Edmunds retested the car after Hyundai fixed a couple issues with the car, and got some better results.

Re: 4b11t going into new RWD Hyundai coupe
 

Awesome that they ditched the quick shifting power cut BS.

Re: 4b11t going into new RWD Hyundai coupe
 

Sounds like my Saab. You can't add too many bolt on mods or the car will detect that it's flowing more then designed, and will throw a CEL and put it into limp mode. Only way to combat it is with some plug n play ecu mods which I'm really not a fan of.

Re: 4b11t going into new RWD Hyundai coupe
 

Also, from what the guys at AEM have been saying, it's gonna be hard to up the boost even on the stock turbo with the stock injectors. The flowed them at like, 335cfm, and they are pushing 97% duty cycle in the upper rpms. They have a set of RC 650s in it now and they seem to be working well with their F/IC piggyback setup.

Inside Line Dyno Test: 2010 Hyundai Genesis Coupe 2.0T

http://blogs.edmunds.com/straightlin...mb-555x370.jpg

Although the 2010 Hyundai Genesis Coupe is offered with an optional V6, it's likely that the turbocharged 2.0T version is destined to be the more popular choice. It's less expensive and lighter, plus it's got a happy spinny thing under the hood known as a turbo. And when it comes to tuning potential, a turbo is hard to beat.

We tested a bone stock Genesis Coupe 2.0T on MD Automotive's Dynojet chassis dyno located in Westminster, CA. Hyundai says its 2.0-liter turbocharged four-cylinder generates 210 hp and 223 lb-ft of torque at the flywheel, and like most factory ratings for turbo cars, those numbers are a bit on the conservative side.

Hit the jump to see the dyno chart and other discoveries.

http://blogs.edmunds.com/straightlin...mb-555x379.jpg

Click on the image to see a larger version:

Peak torque arrives at 2500 rpm and then peters out all the way to redline. Clearly, Hyundai's prioritiy in crafting this type of power delivery was to ensure the Genesis Coupe 2.0T felt responsive around town.

This run was performed in fourth gear. Third gear produced a lower peak torque value since the engine would "outrun" the turbo--the engine revved through 2500 rpm quicker than the turbo could provide the requisite boost.

Here's something to help prop up that torque curve at higher engine speeds. When we were strapping the car down to the dyno rollers, we saw this:

http://blogs.edmunds.com/straightlin...mb-555x370.jpg

As if the Genesis 2.0T's two catalysts bricks and dual mufflers weren't providing enough exhaust backpressure, the company's engineers went ahead and smashed the exhaust down for good measure. Okay, it's that way to provide miles of clearance for the chassis brace underneath, but that it further reduces dangerous horsepower is like a gimmie for tuners.

Re: 4b11t going into new RWD Hyundai coupe
 

Wow, a turboback has got to work wonders on this thing, I can't wait to see some people making big power with these.

Re: 4b11t going into new RWD Hyundai coupe
 

LOL @ the exhaust, but most stock exhausts are pretty much a joke anyways.

Re: 4b11t going into new RWD Hyundai coupe
 

That's hilariously dumb...

Re: 4b11t going into new RWD Hyundai coupe
 

Haha I was about to post that Inside Line report. That stock exhaust is just rediculous.

Re: 4b11t going into new RWD Hyundai coupe
 

yeah edmunds/insideline seems to be on top of this car!

Re: 4b11t going into new RWD Hyundai coupe
 

Maybe it was designed that way to help limit power, aka make the v6 appeal more.

Re: 4b11t going into new RWD Hyundai coupe
 

I really like these cars performance wise, I just hate the way they look.
