    Autocross 1

    Schedule subject to change. Registration will be available closer to the event date @: https://www.motorsportreg.com/calendar/?country=CA&q=Winnipeg+sports+car+club&radius=9999&lat=50.26&lng=-96.98&loc=St.+Andrews
  2. Postponed to Sept 18/19th DirtX will debut this year as a demonstrative discipline Check out more information at DirtX Discussion
  3. The Facebook Event listing says, “Free, duration 1 day” !!!!
  4. Tires with a wear rating of 340, results in -5 PIPs and takes you down to GT3 class
  5. What is the wear rate of your tires? That could affect your class even if you are bone stock otherwise.
  6. Max: according to http://ccdb.casc.on.ca/ your car is in GT2
  7. In discussions with our Treasurer Chris, it seems like there won’t be much point in us submitting budgets for approval at tomorrow evening’s meeting as we’re still in the middle of COVID restrictions which have resulted in the postponement or suspension of most of our scheduled events this spring. As a result, we’ll table the budgets for approval at our June meeting instead and hope that by then we have a bit more clarity with respect to what the rest of the summer is likely to hold. There should be a revised agenda posted to the forums shortly. See you all this evening. Winnipeg Sports Car Club is inviting you to a scheduled Zoom meeting.

  8. Typically not until a week or two before
  9. Oxygen deprivation won’t put out a battery fire. When a LI battery is damaged it shorts out and the energy in it heats it up, which heats up adjacent batteries, which causes them to short . . . and it cascades. It would probably still happen in a vacuum, no flames, but destruction never the less. The only way to prevent the cascading is to cool it until the energy is dissipated in all the compromised cells.
  10. I had been doing some brake work this spring . . . didn’t do it all at once, had changed my rotors, leaving my older pads (over 50% life on them, Carbotech XP10/XP8) on, without brake pad shims. The result was horrible brake noise when moderate braking under 20kmph. yesterday I installed new pads (same composition as before) with titanium brake pad shims. I then went on a bed-in run and 20 minutes of driving through town. NOT. A. PEEP. OR. SQUEEL!! I’m looking forward to Hot Lapping this weekend, new tires, new brakes, new clutch, all new fluids, some new suspension bushings, slightly less tension on the rear sway bar
  11. LastV8: Registration will be available closer to the event date. You are correct on Road Race vs Time Attack. Track day is the Friday, the 11th, no timing, restricted passing.
  12. rusoman said "...brake fluid everywhere..." Sound like either the caliper seals blew or the brake hose blew. The natural response when the brakes fail is to press harder, and if the seals or hoses were overly hot, that'd increase fluid pressures and something blew. So . . . stainless steel braid hoses are called for too.

  19. Others would have to chime in here. I haven’t measured, I’m guessing here: Since it’s only one lap, done in about a minute, with no heavy braking from high speeds, I can’t see that it would be very high. I was mostly addressing your brake fire on track day.
  20. It’s difficult to get a temperature at the point of friction of pad/rotor. In 2019 with stock rotors and performance street pads I’ve measured 600+ degrees F on the rotor, after 10 minutes of hard running track time, and a cool down lap. At that point my wheels had also soaked up some of the heat and were too hot to handle. On a warm day I’d have to limit my run time, my RBF600 brake fluid would boil and I’d loose braking In 2020 I installed a ‘big brake kit’; larger, 2 piece, slotted, well ventilated rotors; Carbotech XP10 pads on the front, XP8 on the back; titanium brake pad shims (thin sheet of titanium placed between the pad and the caliper piston, reduces the heat transfer from pad to caliper). After 15 minutes of hard running, warm day, and a cool down lap, 450 degrees F on the rotor, no fluid boiling, no brake fade.
  21. Changing your brake fluid won’t improve the fireproofing, but using something like MOTUL RBF660 reduces the possibility of your brake fluid boiling at elevated temperatures Boiling produces vapor, which compresses easily resulting in loss of braking, liquid brake fluid doesn’t compress. Get stainless steel brake hoses, when they get hot, they don’t expand like ordinary rubber ones do. If you’re using your brakes hard, regular street pads will wear very quickly when you operate above the designed temperature range. So you need pads that will operate at elevated temperatures. Even street performance pads will wear quickly once they are operating above their rated temperatures Racing pads (like Carbotech XP-10’s) can operate at at temperatures as high as 800 degrees C. See https://ctbrakes.com/choosingcompounds/ Part of braking action is that on initial breaking in, the rotor is imbedded with bits of the brake pad, braking is improved, rotor life is improved. Its recommended that if you change pads, you should change rotors too, or at least give the rotors a sanding to remove bits of the old pads.
