Project Update for August 2, 2011 (part 2 of 2): Sorry for the delay on "part 2", but the construction at the new Vorshlag headquarters is eating up every minute of my day. This past week the demolition inside the new space was finished and electrical work is finally getting back on schedule. Let's finish the July updates for the Mustang while I have a few free minutes.
SW Div Autocross #3 - Our most recent event in the car was a 2-day autocross in mid July, where Amy and I drove it (Costas had work stuff pop up). This was the 3rd of 3 SCCA Southwest Divisional Series events, run on a pair of Roger Johnson courses across the biggest patch of
concrete around, in College Station, Texas. I went to school there (TAMU!) and ran with the college sports car club for many years (TAMSCC!), and even setup dozens of courses there myself as autocross chairman over the years. The area they had acquired for this weekend was the most prime real estate available at this old air force base, and most importantly it was
our first real race in the STX Mustang on concrete , making a great test of the car, just a month before Nationals.

The courses were... very narrow-car-centric, very tight, and very busy. And long - it took 25 minutes to walk the damn things. Cones frakking everywhere. They were very challenging to drive, as is evidenced by the large number of cones hit and DNFs over both days. It looked to me that the small/narrow cars did disproportionally well, due to the narrowness of some transitions (where it was a 3 transition section in wide cars, but a straight in a Miata), but "that's autocrossing". Not knocking Roger, as this is what we see at Nationals from some course designers, and he was probably just prepping everyone for what they should expect. Just can be very frustrating in a wide car like the S197 Mustang.
It was also
damned hot - Texas is in the middle of over 30+ days of 100°F heat, and this weekend in July was no exception. The SW Divisional Steward (Todd!) had brought out two massive swamp coolers and a big tent, and we hung out there during our "off" heat on Sunday, which was a life saver. I was also lucky to score a prime work assignment driving the chase car, picking up the cone sheets between runs, so I shouldn't complain about the heat. Vorshlag being a SW Division sponsor doesn't hurt, I guess! But it was so hot that it became another tire-boiling event, with Amy and I running in the same heat, back to back to back.
This time we brought a new tire sprayer (20X better than the last!), and used melted iced water from the cooler to spray the tires, hitting the rears 2-3 times between runs - and boy were they hot, especially after my runs. Since the run order had us running close together, we had a 5 minute clock on us between runs (grid was very well run), which made driver changes pretty hectic again. I guess the car handled as well as we could expect given the course design, excessive heat, and horrific steering shudder. We had the new ARH headers and cat-X-pipe and custom tune, with 21 more hp at the wheels across the rev range for this event as well. Rear tire spin was again a serious issue, but its just another element we have to work with until we can get the Watts and a better differential (lots more fab time and testing needed). I'd rather have too much power than not enough, but if I was smarter I'd have too little weight and less power, as that is what SCCA Solo rewards. Like, say, a 1900 pound ST car in STX.
That would be fast! 
Our regular, faster STX competitors from the Texas Region were not at this event - the Maxcy's, and Ledbetter's 328is BMWs stayed in Dallas this weekend - so we didn't have much to gauge our performance on, except each others times, STR/STU times, and PAX. Not to knock the two STX competitors who were at this Div, who were in a stone stock RX8 on the OEM tires driving their guts out; they had a lot less prep on their car for the class. My drive in STX class was bad, frustrating, and I coned my fastest runs on both days, which were 1.4 seconds quicker on Saturday and 1 second quicker on Sunday, than my clean runs. I cannot explain this huge gap in my clean vs dirty runs, other than I drove like a hack. I haven't been leaving that much time out there, even in this "difficult to drive car". This was almost as frustrating as the STU Nats win I threw away in 2005 with cones on 2 different runs (as did my co-driver). So this weekend I had 3 cones in 8 runs over 2 days (whereas Amy hit 7 over both days, but never on her quickest runs!), which was still a fairly low cone count for this event (some normally quick drivers had upwards of 3-7+ cones
per run and cone counts in the teens for the two days - it was a busy course), but those cones cost me dearly. Even without those cones, and 2.4 seconds quicker times, my PAX placing would have still been "meh". I was 6 seconds behind STR and STU over both days as well - not a good finish.
