The AMS Genesis coupe is HERE!!! Let the modding BEGIN!!!

**Eric@AMS** · #1 03-21-2009, 06:40 PM

As of 3pm this afternoon we picked up our first Genesis 2.0T Track coupe. Our special projects technician Ivan Phipps just signed the paperwork. We drove it right to the shop and started our long but detailed analysis of what needs to be done.

1. The exhaust is pretty bottlenecked as we expected...big room for improvement there
2. There is CAVERNOUS room for an AMS Turbo kit so see that in the very near future
3. IC pipe and an intake should be able to be worked up very quickly
4. The tuners here are already on the case for re mapping the ECU
5. Looks to be a returnless fuel system so we will have to fix that.
6. Speed density for air metering so a vent to atmosphere BOV should work without a hitch on the car

I can go on all day but how about some pictures to start

Ivan is going to jump in here tonight for a much more in depth analysis

LET THE MODDING BEGIN!!!

Woooooooo hoooooooo!!!!!!

You guys rock!!! :d :d :d

Are you guys going to make any engine parts? pistons, con rods, cranks, flywheels, clutch, etc etc. ??

I'm ecstatic that you guys are on board!!

Got to explore this thing a bit. Here is some specs that might not be published yet.

Front wheel and tire weigh 55 lbs each.
Rear wheel and tire weigh 57.4 lbs each.
Exhaust is 2 3/8" (60mm) and is only 1 3/4" where it is crimped to clear the body brace.
Front sway bar is 25mm.
Rear sway bar is 23mm.
Axles are 1.100" (pretty decent size).
Brembos are not the same as the Evo (although pad size may be).
Intercooler is TINY... 4 3/4 tall, 3 1/2 deep and 20" wide. Upgraded ICs will have to be brought forward where there is plenty of room.

Front bumper is fairly easy to remove. Oil changes should be super easy. It appears to be the same oil filter we use on the 4g63 and 4b11.

The car has many many bells and whistles. I will go into the super pimp ones in a later post. I have to burn a full tank of 87 octane out of this thing tonight so I can get it on the dyno tomorrow.

Here are some quick pictures I took on my phone.

My new coupe sitting outside of Gartner Hyundai

On the lift at the shop checking it out from underneath.

Front bumper cover removed. Lots of heavy steel up front!!!

The tiny cooler at the bottom is the intercooler. The charge pipes are held on with spring clamps!!!

Can you tell what my first mod was?

......and my second mod!!!

Gah!!! Not fair! You guys have the exact car I want!!!!! Gimme Gimme Gimme!

First night with the coupe... my impressions.

First off, I have to say that this car looks so much better in person than it does in pictures. You really do not get a good idea of the shape of a car in 2D. In pictures, it appears smaller than it actually is. This might have to do with the large wheel and tire throwing off the perspective. Pictures make it look the size of a Tib when in person, it appears to be more the size of a G35.

Fit and finish is very good. The interior and exterior both have a quality look and feel to them. The chrome "H" on the front and rear are distracting. I pulled them off and painted them with VHT Nite Shade spray on tint. The chrome still shines though and now looks like black chrome. On the front, this mod fits perfectly. On the rear, the "H" still stands out a bit much for my taste. The car has a very unique shape. Everywhere I drive, there are people taking second looks, pointing and taking pictures. I have heard several people say "what is that?" At the local car hangout, I was surrounded by people before I could even get out of the car and swamped with questions and comments all night. People really like the car.

The interior is very very nice. The seats are ultra comfortable. The dash layout is awesome and controls are easy to use. The stereo system is perfect for my taste. AM / FM / XM / 6 disk in dash CD / MP3 player / iPod cable / etc.... The sub hits hard enough to feel. Steering wheel controls are easy to use and work fine. I wish they had a mute button though. Bluetooth works perfectly and phone calls are clear and easy to make / receive. Wind noise management is awesome. Cruising with the sunroof open is ultra quiet. With the windows down, I could still talk on the hands free. Back seat head room is limited. Shorter people only back there.

The proximity entry is very cool. All you need is the key in your pocket. You walk up to the car and press a small button on the door handle and it unlocks and disarms the system. Pull the handle and the window drops down a 1/4" (BMWesque). Hop in and close the door and the window goes back up. Push the clutch in and push the start button once and it takes over from there. The engine fires right up and purrs. There is enough vibration at idle to shake the shifter but it does not transmit when your hand is on it. Clutch feels nice. It has a bit of pressure to it and feels like a heavier duty pressure plate. Engagement point is in a perfect spot and feels natural. I cant even tell you where that point is as it is placed perfectly and takes zero thought to drive. The shifter has positive engagements and is nice and notchy. Reverse is far left and up. It takes a bit of pressure to get it past the 1 / 2 gate. When engaged in revers, the car lets you know by sounding a long beep. I did find that a quick reverse and pull out into neutral then quick into first seemed to jump me back into reverse. It seems that the pressure required to get into the reverse gate is gone for a moment when you pull out of reverse. I will do some more exploring on this issue today. The throttle pedal has a good feel to it but does not exactly feel connected to the motor. My biggest gripe about this car is throttle control during and after shifts. There is a LOT of throttle hang (rpms stay up when throttle is released with clutch pushed in) which makes smooth shifting an issue. I hope that Hyundai gets this sorted out and has a reflash to correct this problem. Throttle response is good and low rpm power is great. Power falls off dramatically up top though. I do not like the torque curve. When the torque curve flattens out, this car will be a LOT of fun. I will be exploring spirited driving a bit more today and will post up my impressions a bit later.

So far, this car is shaping up to be pretty nice.

Thanks for the awesome review!! I love what I hear about this car, EXCEPT, the throttle hang issue. I currently own a '08 Civic Si and it suffers from the same issue. Everyday the issue makes me wish I could sell the car and get something else. It absolutely drives me crazy!

! Other than that the car sounds like it is amazing! Thanks again for the awesome review and taking the time to do all that you are doing for this community. Props to you man!

I read a review of the Coupe, and after the reviewers complained about the lag, I thought that Hyundai came up with a ECU udpate to fix the problem (at least for the reviewers). Check with your dealer to see what the status is. Mabye I got this wrong, but that is what I recall reading.

The throttle hang issue has to do with modern emissions standards. You'll see this characteristic on more and more cars. Something to do with the throttle shutting off too quickly, not producing a complete burn and in turn pumping out more harmful gases that fail emissions. This was described by Bob Lutz of GM.

looks awesome guys!

We did get a chance to get the coupe on the dyno today. Still running 87 octane. It spools ultra fast and makes peak Tq around 2500 rpms if I remember correctly. Peak Tq numbers were in the mid 220s and peak HP in the upper 180s. Chris will be chiming in with his impressions, dyno charts and comparisons soon.

We did play around with a few things and made decent gains. Chris will post all the details.

93 octane dyno numbers coming soon.

Can't wait to see the numbers after intake/exhaust/intercooler/tune.

i see this being the longest thread in this section.

carlos nice

What software are you guys using to tune this?

We are not tuning the car at all, just doing some small "experiments" to see what happens. We are carefully watching air fuel ratios and boost levels and are logging on autotap.

Boost is quite low and is heavily controlled by the ECU.
