Session 1
Temperature was about 90* ambient and sunny, so this was going to challenge the cooling mods I had done on the car: revised roof scoop and water injection post intercooler.
The first thing I noticed during the warmup laps was how little grip I was feeling, track felt greasy, so either the tires weren't to pressure or they've had too many heat cycles. That sapped most of my confidence about cornerning for the day, I never regained the feel to push very hard.
After warmup I tried pushing on the front straight and hit fuel cut again; so another failure in getting the intake temps to a reasonable level. When I took a look at the IC temp gauges I saw peaks of 200* at the inlet and 170* at the outlet; which is still way high. There is a 5 GPH water injection nozzle post IC, and I verified the system was running as expected when boost was above 12 psi (where I had set it).
So given the car is basically crippled and won't run at WOT on the track, I resigned myself to lapping and trying to keep from blocking the faster cars - which is frustrating.
