Default 1/4 track day - 05-28-2016, 07:17 AM

Had a decent day, however dissapointed by my final ET

I went bone stock, n55, run flat tires, and did 13.7 @ 103

Now MPSS tires, JB4 Map5, intake, charge pipe, best i could manage was 13.2 @ 107MPH. However, it was 90F with 50% humidity, so it was hot as ****

After about 5-6 runs, clutch wouldn't hold anymore on my final pull. was slipping 3rd and 4th so i coasted to the end, and never smelt worse clutch smell in my life. After 40 mins of cooling, and driving back 1 hour in stock mode, i put it back to map5 and the clutch still grabbed nicely.

I need to go back when its cooler, im sure i can hit 12.9!

Also, E92 M3 i was with best he could do was 13.5 @ 110 (intake, tune, exhaust) and also a TTRS, BONE STOCK 13.02 @ 109

I used 94 octane Petro. I believe my ****ty timing is due to it being 30C with 60% humidity.

Hi Lowon! Yes we are from Ontario (Mississauga). If you're around, im sure we would all like to drool on that M2

Dude when I get the car this summer I'm definitely gonna take it to Ontario your tracks lick everything we've got in western Canada.
Btw do you have access to husky 94 it's better than petro 94 from my testing. The reason is petro adds way too many additives to their gas diminishing octane quality.

Depending on age of clutch you may want to just change it out. Mine gave up on me at about 70k.

You guys really don't need to worry about the clutch too much, some will last over 100,000km, some less based on driving style. You'll notice it slip slightly way before it becomes an issue, think of it as a early warning.
