VIII looking for 8s
I hit the track for the second time this last Saturday and unfortunately I encountered a couple problems. The first one being the heat. The temperature in the morning was 72 degrees and quickly climbed into the 80s. My best time was a 14.275 and that was in the morning when it was still in the 70s. Throughout the day, the car seemed to get slower and slower, and my average times were about 14.4
With the exception of the first two passes in the morning, I did all of my passes manually shifting which leads to the second problem which is more of a concern to me.
My buddy Dan and I decided to leave earlier than everyone else in hopes to get a few cooler morning passes in which paid off in a way because the temperatures quickly rose and my best time would have never been attained otherwise. It is about a 2 hour drive from his house to the track over in Eau Claire. As I am following him on the highway at about 70mph, I am noticing that the car feels as if it is on the very edge of "lock-unlock" in the torque converter. The rpms as we are at 70 mph are fluctuating back and forth about 100 rpms on the tachometer and the converter almost seems to be locking-unlocking. I should have payed more attention, but couldn't say if it had anything to do with throttle input or not considering the highway wasn't completely flat and I wasn't using my cruise control.
As we turn into town off the main highway we get on the offramp and approach a yield sign going to the right, Dan slows down and then as there is no traffic this early in the morning he gets on it wide open throttle and I do the same behind him. The car shifts awesome out of first into second gear, and then all of a sudden, the car drops out the rpms and then downshifts again causing this big gap where the car isn't even accelerating and then the power comes back and it proceeds to accelerate
This is precisely what happened at the track on my first two passes which almost made me want to turn around and go home right there, but I toughed it out and manually shifted the car. I am also wondering if the tuner this last week messed with something torque-converter related in the tune in an attempt to solve the "warble" that I told him about with my dyno graph earlier this year. Either way, the problem is VERY pronounced when I did my first two runs at the track.
I tried to make some videos this evening from a dig and going onto an onramp but the car wouldn't do it.
