  1. The morning/afternoon event is on the skid pad. (The old runway between the road course and the kart track) Then, once road racing is over, we have a second event on the road course. Two autocrosses in one day!

    Event 2 - May 12, 2018

    Hard to do in text, but I'll give it a shot. Disclaimer #1: If you're not a course design nerd, just skip all this. Disclaimer #2: Please don't take this as criticism or complaining! I hugely respect the effort, skill, and artistry it takes to make a good course that makes most people happy. This is meant as my personal wish list based on what I've experienced and loved about other courses. I tried to do this when I was course designer even though I rarely achieved it. Here's an example of what is not fun and leads to many cones being hit: If someone were to design an entire course consisting only of 2-cone pinches, where you had to enter at a precise angle, squeeze between the two cones, and then set up for the next 2-cone pinch, that would be very demanding and have many cones hit as there is very little line selection. Similar is a corner with a restricted exit, i.e. a wall of cones that pinch off the exit. An example of a fun course with few cones being hit: Saturday's course. Aside from the wall right off the start and the chutes near the North, there's nothing to hit if you go 5-10' wide of the racing line. The line is set by trying to get to the next section cleanly, not by a wall of cones in your way. That lets people make mistakes without smashing a bunch of cones. Interestingly, I think more cones were hit by experienced drivers trying to get close than by new drivers. We do still need some of everything to test our abilities (big sweepers, technical stuff you need to squeeze through, etc.), but the general trend in small regions, like ours, is to take huge elements from big SCCA courses and shrink them down to 1/2-scale to fit on the space available. I know I was definitely guilty of this as a course designer - what was a gloriously fun element on acres of concrete became pretty un-fun when scaled down to fit in our lot. Whenever I go to US Nationals, I'm stunned at how much line selection there is, which leads to me struggling to figure out where I want to try to cut distance vs. maintaining speed into the next element. I don't have the answer, but I'd like to have more line selection at St. Andrews. Day 1 from 2017 Nationals: https://www.youtube.com/watch?v=MLCOC84wWUI @0:21 - If you swung wide on the exit, it made the next slalom entry dramatically harder, so it was better to end the sweeper on the inside. There are a few examples of this in the next few corners too. You can room to go wide without hitting stuff, but it hurt the next turn. Day 2 from 2017 Nationals: https://www.youtube.com/watch?v=mJRAJU8sytM @0:44, I tried to stay tight on the exit through about 0:48. I thought I was being smart as I was cutting a huge amount of distance, but it was the wrong choice. Note the amount of OPR (other people's rubber - really mostly seam sealer tar) I'm picking up on the right front tire as few people drove there! Watching the 2nd place guy's run, he got on the throttle earlier and carried that speed all the way to the next significant corner at 0:54. As much as I don't like making the mistake, I did like the fact that you had to chose wisely. For reference, I did most of those courses in my 2nd gear with occasional shifts to 3rd and even 4th for the finish. At our recent event I was all over the limiter in 2nd on the first run so I did everything but the hairpins in 3rd and the finish in 4th. Our average (median? ) speeds are higher than Nationals, despite how the videos above feel.

    Event 2 - May 12, 2018

    Wow, I loved this course! It gave you room to make errors with few cones on the outside of the corners. You could go off-line without smashing cones. Much preferred over tight squeezes end-to-end. We still need some of those to test your car placement skills, but fewer than we typically have. Here's my fastest: The two chutes were very challenging to see. Too many cones, with non-parallel walls and uneven spacing. I just floored it and prayed it would all work out after the 2nd last slalom cone. It was a blast working the mic for the rookie heat too! So many pumped people and huge improvements through the day! I'm sure I got some of your names wrong, sorry. Just come let me know (before or during) if I butcher your name. Max I. was able to teach me how to say his name (close enough?), so the rest should be no problem!
  4. I finally got around to processing my video: Comments: Wow, am I glad I got to shake the rust out at the fun run/T&T day the day before! That made for a nice entry back into autocross rather than coming in cold. Listen for the frame touching the ground at 0:20. I haven't lowered my car, so the road crown probably got steeper over the winter. Weird! It touched in that area the day before as well. No big deal, just interesting. 0:35-ish was pretty hairy! It took until the 4th run to stay ahead of the car. Going into the finish line into the crazy headwind meant my helmet was lifting, even with the stick-on spoiler. I need to do something else before hitting the track at Gimli! Maybe a little windshield/lip on the dash like the F1 guys do...

    April 29 commentary

    Yeah, I just worked stop box and I was exhausted once home. It was great seeing familiar and new faces, and driving fast is neat too!

    test and tune on April 28th?

    Sorry, just saw that this was clearly stated on msreg.com. Thanks for confirming!

    test and tune on April 28th?

    Do we have a food vendor for Saturday or Sunday?

    Permanent numbers

    Fiberglass doors on the Vette. :/
  9. No worries, my statement could be taken in a way that was completely wrong. Better to clarify!
  10. Right, thanks for the correction Mat! I meant that the lapping session ran for a certain time, but can't English today. English is weird, but it can be understood through tough thorough thought, though.
  11. Hot laps are time-based sessions on the Friday of race weekends. If there are few cars and your car can take the heat, you can do a LOT of laps. I recall Deacon doing 100+ laps some years ago. He'd come in from one session and get right back in line for the next.

    Join SCCA

    Make sure you specify Badlands region. Not only are they closest to us, they have some of the cheapest club fees in the SCCA. When I last called they REALLY wanted to put me in the Chicago region, because "it's close to Canada." Took more effort than it should have to talk her down from that idea.
  14. I bought these last year and finally got to (ok, had to!) use them this morning. https://www.tracgrabber.com This is not a paid review. Result? Not bad. They don't add 100% more traction, but in the medium-density snow they got my FWD car moving again. They probably added 30% more traction. Enough for me to get out of trouble on flat ground with lots of rocking back and forth. As a negative; they sound and feel HORRIBLE. The first time I tried moving I got two loud bangs that had me out to check what was going on. Every time they hit the ground/snow they put an almighty shudder through the car. You really need to turn off your mechanical empathy when using these. They're nice to have in your trunk to help.
  15. Yeah, being easy on the throttle just changes the frequency of the banging. Maybe the dense snow today amplified the effect. :shrug: Either way, they're staying in my trunk! I doubt you could get them on steel wheels. :/ Even then, the strap might get cut as they slip on the tire pretty heavily. It was neat seeing the volume of snow being flung forward when rocking backwards. I dug some pretty serious trenches by the time I was out. You really need to get in the wheel well to install them though, plan for a dirty jacket.

    Spring Nat's 2018

    I'm in for the house! No ProSolo for Canada house? Granted, I'm not sure if I'm doing the Pro yet.
  17. Nice read that doesn't get too deep into physics: https://beyondseattime.us15.list-manage.com/track/click?u=16dabff8d4e129704dee5886c&id=b9b4c2d8e8&e=d8b2c525e5

    Spring Nat's 2018

    I'll probably go. A house could be nice. Might attend Pro Solo, but don't want to switch accomodations part-way through.
  19. Post any cool car videos you find here.Pagani Zonda laps the Nurburgring in 7:27, Episode 5 on the right: http://www.supercarmovies.com/html/interface.htmlActually, all the clips on that site are pretty cool. :eek:
  20. I haven't listened yet, but saw this pop up on my feed this morning: https://play.google.com/music/m/Dl7xwovjzscf422n5rulkct5pme?t=055_Danny_Kok_Ice_Driving_Making_a_Racing_Comeback_-_Speed_Secrets_Podcast

    Brake Fluid

    Useful for Subaru owners - I recall my clutch being stupidly stiff after a long drive in -30C. Also for any cars with a clutch-delay valve.
  22. If they can do a peanut-free kids meal, I'll bump mine up to 3 people. If not, just 1.
