Figured i'd post a few videos from yesterday. I had fun, but probably not as much fun as you guys at Pho!

Enjoy

i can't see these at work

That looks a lot of fun. I've never gone to high plains raceway. I'd like to go one of these days.

[forza1976]

It's definitely fun. Just really hard on the car.

Sweet dude! What DSC setting did you have your car on? I cant wait to take the M out there this year. However, I do still need some more practice in it because it drives way different then my 335.

I only clicked it once... Just to get comfortable and remember the track for the first two sessions. The third I turned it all the way off... It was fun!

As if Bandimere wasn't hard enough on our cars.

Here's mine, thanks to Matt!!! It is ~long~, and was almost the entire session I had with Matt's camera suctioned to the roof, and Matt in the passenger seat. Check out the Porsche at 6:30, and the mistake at 14:47 going into turn 8. (It's the last time going 'round.) It doesn't look like too much in the Video, but I think Matt thought we we're going into the weeds. Edit: the Porsche that passes me is at 1:00 of Matt's 3rd video above, yes, I pointed him by, but I didn't need to, he was soooooooo fast.

Nice lines Alex. That was a fun couple of laps.

[Bimmer This]

Nice video's guys!

What were your top speeds at the end of the long straightaway before the downhill turns?

I lapped HPR last year and could only get to 125mph. My car is a stock 335xi.

130 'indicated' sounds 'bout right. I often miss seeing that, because I'm too busy looking out the windshield, and even a fraction of a second delay could be disastrous. In the summer, (but not in the vid/that day) I threshold brake to about 75-80 mph, well, that's what I see after finishing that turn, which is turn #4. I marginally accelerate out of apex with that turn, I mostly just try to "survive" it.

stamd1, did I meet you in Pueblo at the October event?

+1 on watching out the windshield.

No. HPR is the only track I've been to. We might have met at Bandimere last year. I showed up late and could only make one run which was a 14.2 at 98mph.

What was the most number of consecutive laps you ran?

There were very few people when I went but between feeling like I was totally abusing my car and the brain fatigue from concentrating I would only do 4-6 laps at a time.

Did you lower your tire pressures before lapping?

You raise your tire pressures. 42psi is a good starting point for these cars

I'm a nerd. Based on my experience chalking the tires, in summer at HPR with Yokohama Advan Neova AD08s, I start with 42psi in left front, 41.5 right front, 41 in left rear, and 41 or 40.5 in right rear. (Due to course being predominately right handers.) I subtract 1psi for cooler weather. The left front will be at 47-48psi when I come off the track. When I used Potenzas RE050As, those would be at 49-50psi off the track! (Maxed!) If I didn't have the tires this high, I would get excessive shoulder wear, especially on left front tire. (You leave/scrub the rubber on the pavement especially on turns 2, 6, and 11.) Anyways, next year I'm going to Hoosier R compounds and max camber up front, whatever the Vorshlags give me, 3.2 degrees or so. I'm at 2d in the back.

As for number of laps, I've gone entire 30 minute sessions, 12-13 laps. I do get tired in the afternoon, and you ~do~ have to drink a lot of water, and eat too.

Good info.
Some uninformed driver when I went out there told me to lower my tire pressures since higher pressures will result in a smaller tire contact patch. After lowering the pressures for my last set of laps, I could feel the shoulders rolling under.
I also pulled off a newbie mistake. I arrived at HPR with only 1/2 tank of gas thinking I would lap quicker with a lighter car. My 1/2 day turned into a 1/4 day since I quickly ran out of gas.

matt, i'm jealous!

[forza1976]

Yeah, it was a fun time... You can see why Alex and I had to miss the meet last Sunday

[Kayani_1]

Great videos and driving looks like you guys had a lot of fun....
