Went to Thompson this morning… Forgot how crowded this event gets as it’s only $10 to TNT and it’s all for charity so it was a total zoo! They stopped allowing cars in when they got to 600! Needless to say I wasn’t too happy as I was hoping to get a few passes in and then bail. I only ended up making one pass as it would have been another 3-4 hours before I could make another and I have some things to do today. Given it’s only getting hotter my times weren’t going to improve either so just not worth the wait.
Car: 2015 Porsche Macan Turbo, 6,3xx miles, Cobb tune 93 octane file, BMC filters with lids on, full weight including spare and tools with about 1/4 tank of Shell 93 pump gas. Options that may matter: Chrono, PTV, SE AS, 20 inch spyder wheels with a/s tires. 39R 36F. Traction control off
Conditions: Track 1,230 feet Temp 79.0 BP 30.20 RH 82% for a DA of 2,839 which is pretty bad!

1.6822 60ft
5.0272 330ft

108.67 mph
Overall, it’s close to what I was expecting given the conditions and IAT’s when I started, was hoping for 12.2x but not too upset. Probably cost myself a few hundredths as I didn’t shallow stage as much as I’d like because the damn hill hold came on and I was able to perfectly creep up to the line. Thought I’d see closer to a 110MPH trap but not today. Truck launched and shifted fine, I know it has a better 60ft time probably a low 1.6x and maybe 1.5x on race fuel which I’ll try soon. Still reviewing the logs but I notice the tune totally retards timing when using LC after you launch for a tenth or two. Not sure why Cobb is doing that, maybe to save the tranny given the tq? Also, a few cylinders had timing pulled to the tune of 3-4 degrees the entire length of the strip. Overall timing was a little lower than I had expected to see but again this is probably a result of the conditions and IAT’s, as I’d prefer to pull timing then have detonation. IAT’s were horrible at 123F when I launched and about 118F going through the traps so the coolers are doing their job fairly well it’s was just to damn hot and sticky and I started with too high of a IAT given I had to sit and the truck never fully cooled down. Still going over the logs so I’ll add more as I review more.
So my best stock was 12.59 but that was in a 342 or about 2,500 feet better. On my S4 that’s easily 2-2.5 tenths and 2-3mph… Fairly confident with a perfect launch in great conditions I’ll go 12.1 on pump and probably 11.8-11.9 on race gas/tune. Will see over the next few months!
Also, had my gopro but forgot the dang memory card wasn’t in it so unfortunately not even gopro vid. There were a few regulars there so I’m hoping someone got a vid and sends it to me and if so I’ll post it. I’ll be going pretty regularly starting in Sept – Nov. so I’ll make sure to get vids in the future.
