Genesis Coupe Thread

[YSSMAN]

Edmunds ran a chassis dyno of the 2.0T recently as well, and it was putting down over 190 WHP. Not bad at all, which likely means Hyundai is underrating the turbo models.

Very good news indeed!

 

[JCE]

190whp? That's pretty good considering the factory claimed crank "rating" is 210bhp. So assume a 20% drivetrain loss the actual bhp is what--around 228~230bhp?

 

[Omnis]

I'll try to find pics of the stock exhaust system, though. It's disgusting. There's literally a huge kink just before the Y-pipe. I imagine the engine will perform much better when it's no longer suffocated and constipated.

 

[JCE]

I would imagine Hyundai did that on purpose. I would hazard a guess that with an ECU tune, intake and exhaust alone could net over 60bhp easy. I can't wait for the Tau V8 in the Gen Coupe!

 

[YSSMAN]

I was under the impression that the Tau "didn't fit" in the Gen Coupe? Or is this all internet rumor?

 

[Jay]

Free up the in's and out's, increase boost, good tune (much leaner than that stock pig tune) to suit and I think it will get a nice chunk of power.

What the stock boost anyway?

It should fit... it uses the same motor mounts. Problem is, it would throw off the weight distribution too much.

I've read 2.7psi at the manifold. I have no idea though-- especially in regards to that dyno.

 

[Tornado]

Motor mounts don't mean much. The Ford Modular engine can attest to that.

 

[Omnis]

Yeah, true. I'm more excited over the supercharged Tau that's supposed to go in the sedan than a Tau in a Coupe. That thing will kill babies.

 

[Tornado]

Now, the 2.0T is essentially an Evo motor, right?

 

[Omnis]

Now, the 2.0T is essentially an Evo motor, right?

Similar, but not identical. It's open, for one.

 

[Tornado]

Open?

 

[niky]

EDIT: Maybe open as in open-deck? I think I recall that the basic 4B11 is an open-deck design, but the EVO version has more buttressing than the NA motor inside.

---

Yes, and no. Yes in that they have the same basic block, and there are similarities in head design. No in that intake and exhaust manifolds will not bolt-on, cam grinds, pistons and rods are different (and probably crank, too... EVO internals are forged), and the Hyundai block has less structural stiffening than the Mitsubishi motor.

Also, the ECUs are different.

I'm still hopeful that EVO internals and cams can swap over... because there are some wild cams available for the EVO out there...

(Posts something extremely long and technical about the fallacy of predicting bhp from whp, then realizes he's typed this in length before).

Can't predict BHP from WHP. But yes, that's a pretty healthy number. No reason for Hyundai to under-rate the 2.0T when they can just de-tune it. Of course, we all know detuning is so that it doesn't cramp the style of its V6 big bro, right?

And... if it were actually making 230 bhp, I'd expect it to get to 60 a heck of a whole lot faster than 8 seconds.

I was thinking V8 powered Evo more than Evo powered Genesis.

 

[Omnis]

EDIT: Maybe open as in open-deck? I think I recall that the basic 4B11 is an open-deck design, but the EVO version has more buttressing than the NA motor inside.

Yeah, open-deck. The evo is partially closed. The evo also has a double-bolt setup for something in the block. I forget what it's called. So the evo has 2 pairs of bolts for each cylinder and the hyundai only has one pair. I'm not too savvy on the deep innards of engine construction.

 

[niky]

Oh... all that means is that the cylinder bores will likely flex less under load, allowing the EVO version to potentially support a mackload more power... that and the forged internals, that is.

RE: V8 powered EVO: Sorry... RWD to F/AWD... no can do... at least, not easily... And I think the V8 uses a different transmission, to boot...

But if you mean this Hayabusa-based, 2.8 liter, compact, 400+ hp V8:

maybe...

You see, American cars have me spoiled. Don't like the power of your Chevy Blazer I4 but don't want the 4.3L V6 in it? Drop a Corvette motor in there!

 

[YSSMAN]

It should fit... it uses the same motor mounts. Problem is, it would throw off the weight distribution too much.

An unfortunate problem that Ford would be happy to tell Hyundai all about...

I'm betting they'll do a Tau-powered SEMA project, eventually. But, I assume Hyundai wouldn't do it until they know for sure that both versions of the Genesis are sales successes.

 

[Bones Brigade]

And... if it were actually making 230 bhp, I'd expect it to get to 60 a heck of a whole lot faster than 8 seconds.

Motortrend says 6.8 seconds and a 15s 1/4 mile.

 

[Omnis]

More good news, everyone: AEM is working on a turbo engine with a tune and new injectors that won't crap out after 5.5k rpm. Then they'll throw on breathing equipment so we can see what it can really do.

 

[niky]

Motortrend says 6.8 seconds and a 15s 1/4 mile.

Okay... my objections all go out the window, then...

Of course, Motortrend also says the MX-5 can do 0-60 in 6.6 seconds... and that's a 160 hp car... and, for the life of me, I can't even get close... (best 0-100 km/h is about 7.5... probably a flat 7 for 0-96)

well, in this case, I'd give MT the benefit of the doubt, given these dyno results.

 

[Omnis]

It was only a matter of time:



Too bad about the park bench on the trunk. But it's the first dori-dori turbo.

 

[Paulie]

I didn't know which thread to post this in sorry, so this one with so much attention gets it.



Too bad for the Genesis, and if I didn't know better judging from that video, the Mustang looked faster 0-60, but they say the 370Z was faster.

 

[Jay]

Those times they list wouldn't have been from that demonstation race they showed, they would be their official recorded times after multiple attempts.

 

[YSSMAN]

Even then, it still misses the point that, for the most part, they're all pretty radically different cars. My alliances still like with Ford and GM on the issue, but I'd rank the Genesis pretty high because it is a great effort that comes with a very good price tag. The car could be an absolute dog in straightline performance, but as long as it rides and handles exceptionally well, it comes off as an attractive purchase.

The problem I'm having with the GenCoupe is that even as the "value" car, I'm not being moved by the cost difference to hold it that much higher in regard versus a Mustang GT or Camaro RS. All of which, while I'm thinking about it, makes me wish that GM would have made a proper Z/28 with a 350 BHP small block to bridge the gap a little better.

 

[Stevisiov]

What version of genesis coupe did they use in the drag race?

The 6. I hope it was post re-flash. Pretty sure it was.

 

[Paulie]

Radically different cars, that despite their differences, were aimed squarely at each other from the outset, especially the Genesis Coupe v Mustang.

All three of those cars make a super sexy noise. I'd still take the Mustang, then the Gen coupe. The Z and Mustang GT are pretty close on every test--too bad the Mustang GT can't get a 6spd. I can't believe the GT and Z put up such an awsome 1/4mi time.
