Tire spin?

I believe you may be talking about this one: http://www.edmunds.com/car-reviews/track-tests/2012-hyundai-genesis-50-r-spec-dyno-tested.html

I liked the little slip in the article about dropping the 5.0 TAU into the Genny coupe. That would be a true rocket.

Thats the one. One would expect between 10 and 15% power loss through the drive train. However, (running the numbers myself) there is about a 20% loss according to that article.

In conclusion Hyundai is optimistic with gas mileage ratings, also optimistic with power ratings..... hhhmmmmmmmmmmmmmmmm

Maybe I'm reading a different link than you guys but I don't see the problem. For an automatic transmission, 15-20% (usually on the lower end of that) power loss is normal for a RWD car. It made right what was expected, even given that Dynojets do read high. Keep in mind that gearing HEAVILY skews results. A 6-speed auto with better gearing and done in the right gear will make more power to the wheels than an 8-speed auto with gas mileage oriented gearing or testing done in the wrong gear even if the engine itself on the latter makes notably more power.

Fellas,

It's on the dyno - of course it's going to be low... lol

Depends on the dyno I rate autotragic boxs up to 25 perent.
Converter plays a roll too.

As OP of this thread, I find all the comments interesting.

To-day, I found myself on a freshly gravelled road, just packed with a roller by the looks of it, nice loose stuff.

Come to a stop, trans in "D", push the pedal right down. A very short wheel spin, the engine sounds like it's bogging, but the car accelerated smoothly and straight. I could hear a little bit of gravel coming off the rear tires. A little disappointing but safe.

Come to a stop, trans in "D", turned the ESC off. Push the pedal right down. The tires immediately broke free, spinning and throwing gravel like a good thing, tach was up around 5000 rpm. The rear end started to come around and I had to correct for it with steering before I did the sensible thing and took my foot out of it.

I tried both ways, ESC on and ESC off a couple of times with the same results. Even the wife commented on the difference.

My conclusion, on the 2013 3.8 Genny, the ESC will eliminate traction control and of course eliminate the Stability control when you push the button in and ESC OFF is lit up on your dash. From what I experienced, with 333HP and rear wheel drive, the ESC is essential to a safe drive, especially under poor traction conditions.

I had my Corvette at a road track for hot lapping once, I asked an instructor if I should turn the stability control off (called COMPETITIVE MODE) or leave it on. He suggested for my safety and the sake of the car, leave it on. I think I'll apply his suggestion to my new Genesis too!!

On my C5, if you push the ESC button quickly, it turns everything off (not a good idea). If you push and hold the ESC button for about 5 seconds, it turns the traction control off, but does not totally kill the stability control. Makes for the best times on a road course.

On the Genny, it'll turn off the traction control but not the stability control. If you turn it off and then do a burn-out, the stability part will kick in if you get out of shape very far.

...Keep in mind that gearing HEAVILY skews results. A 6-speed [manual] with better gearing and done in the right gear will make more power to the wheels than an 8-speed auto with gas mileage oriented gearing or testing done in the wrong gear even if the engine itself on the latter makes notably more power.

QFT.

And don't forget weight. A 6-spd Manual with track suspension and over a 1,000 fewer pounds is just faster in every way and far more nimble, even with a comparable engine or even a smaller engine, or with a bigger engine in the heavier car. Scientific facts like that are often lost on this Anti-Coupe/Pro-Sedan site.

I have no problem getting around 5-10 ft of forward wheelspin with ESC off, reving to around 5k in N, then dropping into D. This is in a '12 3.8. I don't do it often as it can't be good on the transmission, but have have a couple of times to see if it can be done. I also don't have much trouble breaking the rear-end loose in a turn with ESC off, especially going up hill... it does take over and real things in, but it at least let's it get a little loose first.

I think your transmission and rear axle would be happier if you applied the brakes and then loaded things against the torque converter before releasing the brakes. You will likely get as much rubber.

Holy crap no. Neutral bombs are bad bad bad news for the trans and dif....
