As it should be!!!
There's a bit of a white-knuckle moment at 1:59 when he's setting up for a turn and goes off the asphalt and into the dirt...
Cheers

Wow . that is the first time I ever heard a 928 that sounds exactly like Blumaxx. I just loved listening to it! Great driving too. The car will want to go out on you if you push it hard (been there before). Wonder what tires the car had on it.

It appears that he sets up the left corners much better than the right turns.

Never seen that before & love it - looks like me driving to the airport on Mondays

Car looks very well balanced and planted for most of it, but at 3:10 and the turns after you can see he's losing the rear a bit. Has plenty of space left in those rear fenders to up his rear tire width some to not grease up the rear tires by the end of the run.

Turning in and apexing too early, consequently he "runs out of road" on the exit - late apexes are tidier, faster . . . . and cheaper.
Too slow in the fast corners, too fast in the slow corners.

Oh my gosh, EVERYBODY!!!! turns in to early. Please if you can learn anything about driving, turning in to early is the slow way around a corner. Just think about it, your braking too early and not getting back on the gas soon enough. We are not driving F1 cars. ALL street cars are pigs and need all the help they can get by getting back on the gas sooner.
I love doing this in my SUV to guys in corvettes and other fast cars. They will catch you in the straights, after a bit. But you did **** them off. LOL

Only the slow drivers "turn in too early" . . . . until they crash, of course . . . . . .

- compared to race cars, most street cars are "pigs", BUT, getting on the gas sooner, on a poor line only leads to tears and $$$$
- going through a corner on a proper line - stay out wide, brake later, enter the corner on a late apex, all allows the driver to go to full throttle much sooner, while keeping it out of the scenery.

If in doubt, check some of Ross Bently's or Leh Keen's videos.

.and, obviously, doing this on anything but a competition environment is foolish and irresponsible.

Fun to watch the weight shifting around on that 928. The Skinny tucked rear tires are notable, perhaps that that's the secret rotation sauce for the 928. That 928 seems to transition nicely too. I wonder what the setup is, anyone know?

How about, ".... which oil pan and breather setup is he running?" I won't pick it apart, I've done a high speed autocross up-and-down a mountain in Hot Springs , Arkansas.... cliffs, boulders, rock walls, and Armco inches away is pretty intimidating... I say TWO THUMBS UP!! Ken

Plenty of factory "built-in" understeer there,
which is what is limiting this car.

Wider rear tires (a common mistake of 928 owners) would just make this problem worse.
The first "step" in making a 928 "faster" through the corners is to eliminate the understeer and get to the point where the car is neutral or oversteers a bit.
.....Every single time one needs to "lift" to get the front end to bite and turn in, is time/speed lost.

Easiest way to cut understeer is a small front sway bar (OE 78-80) and wider front tires...

So, is that "smaller" front sway bar actually smaller?
We've played around with the two, quite a bit, on the same vehicle.
Yes, the earl one is smaller in diameter, but it is solid.
The later sway bar is 2mm larger in diameter, but hollow.

Did Porsche increase the diameter to decrease the weight, only?
