The event did get rained out although they still held the "pro test session" on Friday. My crew couldn't go and it was overcast and a chance of rain although they did make it all day without rain.

We did make it out this past Saturday to test. Just a normal test-n-tune day. Prep isn't great on those days, plus it was cold and overcast. Started out in the upper 30's in the morning to a high of 52 when we left. Running a 315 radial with a nose heavy car is gonna be a challenge. Not sure I can make it work consistently, but I'm gonna try for a while. I have 27+ years of racing on a radial and really wanted to try and stick with it. If it becomes apparent it's just not gonna work, I'll be forced to change to a M/T 3062W 29.5 x 10.5W bias tire.

Car had come traction issues. Four attemps and spun every time. Shock adjustments each time, no change at all though. Came home, looked at the data and also the pictures the track photographers posted and decided the car needed a 4 link bar change. Spent the last two evenings with the car on scales measuring and plotting the 4 link again, then moving the bars.

One other issue on track is the air shifter wasn't activating. I believe it's a problem with the programming in the Holley EFI, so I gotta look into that later this week.

Car felt good, brakes bed in on the first pass and feel good, so once it hooks I should be good to let it ride out to a full 1/8 mile pass.

I'll post some pictures once I get a little time to upload them.
