Event: Sigma Racing Time Attack #2
Track: Mosport DDT (CCW w/ 2 kinks), Bowmanville
Weather Conditions: 24-29°C sunny
My goal for the day was to break into the 1:08's. Considering my best time last season was 1:09.53 on RA-1's it was an ambitious goal for StarSpecs. But I've come to realize that most of the time it's not the hardware that limits your potential lap times but rather the driver.
The weight reduction, chassis bracing, and brake cooling added a lot to my confidence level in the car this year. I was looking forward to setting a new personal best.
Test & Tune
A friend of mine once taught me the ghetto way of measuring tire temp without a pyrometer. He said you should be able to keep your hand on the tire for 1-2 seconds before having to pull it off. If it burns you right away it's definitely too hot, and if you can keep it on for any longer, they aren't up to temp yet. I didn't bring a pyrometer this time so I resorted to his method.
DDT is a really twisty track. The amount of steering inputs here, compared to TMP, is way higher. There are also elevation changes. I started off with dampers set to +16 all around and eventually settled at +24. Although no setting made me happy*
*I wrote up a really long rant about my coilovers but I deleted it to save myself the QQ.
Best Lap Times
Session #1 - 1:12.46
Session #2 - 1:10.24
Session #3 - 1:10.60
Session #4 - 1:10.66
Session #5 - 1:09.40 (new best)
It was a struggle for me to break into the 1:09's but I eventually did it after running my fuel level down and riding without any passengers.
T1 - braking earlier and cutting more
T2 - braking earlier but with less pressure and carrying more speed while turning in shallower using the curb
T3 - downshifting into 2nd and using the extra torque to carry me out using the full width of the track
T4 - braking earlier and cutting more (needs work)
T5 - braking earlier and cutting more, accelerating earlier (needs work)
T6 - no changes other than hating my dampers
T7 - more throttle, but stabbing brakes to get the car rotated in the right direction
T8 - earlier WOT, cutting more
T9 - higher entry speed due to more confidence but I think I can go even faster
T10 - no changes but I need to get better at hitting the apex
In summary, I'm just cutting corners a lot better this year. Here is my attempt at explaining to Gutantag (passenger) on how to cut the curbs lol. As you will see I'm still far from being an instructor
Here's a video from my last test & tune run of the day. Somewhere in there is my 1:09.40 lap. I chose to upload this one because lots of interesting things happen, including almost rear ending two cars, a chase with a Porsche 911, and some cars deciding to cut the grass lol. You can also hear how underdamped my car is as I bounce out of several turns. Chug chug chug chug. I need better dampers!
Official Time Attack
No footage this time as I was fumbling with my GoPro as Raf was sending us out. When he sent me out I hit the power button instead of the record button by accident :(
(Unofficial) OTA Lap Times
OTA Lap #1 - 1:09.18
OTA Lap #2 - 1:08.94
3rd Place - Group A (1:09.15)
There was some variance between my AiM Solo and the MyLaps times as it showed my official time as 1:09.15. I was happy thinking I did a 1:08 after coming off the track but then instant heart break when they revealed the official times LOL. That just means I need to work harder to get an official 1:08 on the SRTA website...
Congrats to MIBAgentQ on his 2nd place with a 1:08.91! Also great to see other TSC'ers Lord_Sid and kwan_1104 setting new personal bests and Gutantag for attending his first time attack. I gotta watch out for Kwan as his lap times at DDT are creeping up on me! 1:09.96 for him during OTA for a 4th place finish right behind me.
Big thank you to SRTA for putting on yet another awesome event :D
Next event is CSCS #2 at Grand Bend Raceway. Never been there before so it should be interesting.
