The track was Castrol Raceway in Edmonton, elevation somewhere around 3800 ft. Temp started at ~60 and went down to about 50.

Car was running Shell 91, tires at 22psi.

The problem was obviously traction. It was too cold to hook up. But I did notice that when I got to about 5500 RPM in 2nd, the car felt like it shut off. Didn't do that in 3rd or 4th.

Best time of the night was 13.79 @105. Best 60' was 2.28.

How do you guys with manuals launch?

Last night I found running with the car in sport+ ran the best. I'd hold about 2000 RPM and feather the clutch out, otherwise it was massive wheel spin or wheel hop.

Last year my best et was 13.05 @114, I think my 60' was around 2.1.
That sounds like your problem, I have to wonder what would do this, did you check for any codes? Are you sure you didn't hit the rev limit?
