Car ran very well today at PIR. Last time I was there I ran a 1:13.3 on street tires... This time I broke through 1:10 in my second session and third session posted a 1:09.5! Pretty happy with that result.

The car weighs exactly 3,175 with me + full fuel... my dyno was 300whp and optimistically I will gain +20 with a tune, which means my weight / power ratio is 10.0. That is too far off the target for "TTS" of 8.7, so I am now forced to change plans. I can either go SC and tune it for 375 or so whp, or I can try to get the car classed 1 level down to "TTA". The later option sounds very appealing because the time I turned today is a typical winning time in TTA - or close to it.

In order to move down 1 class, I have to do the following:

- switch to no larger than 275 series tires (run 275 square)
- switch from Hoosier R6 to Nitto NT01
- swap back OEM sway bars (but I can run 18K/16K spring!)
- add 100 lbs of ballast, for comp weight of 3,250 (note: can add ballast wherever I want)
- remove canards
- remove front splitter (didn't have on today anyway)
- convince NASA that my sport model Z is equivalent to a non-sport for classing b/c I swapped out the brakes, wheels and diff and those are the only real differentiators... they may require me to run without SRM, however

Another thing to note... I was pulling sustained G's today upwards of 1.30 and as a result had fuel starvation with only 1 light down from full!
