|September 13, 2010 - New video!|
I've put up a clear lap of the High Plains Raceway. I have a few more with me chasing down various cars, and I may put them up later. Janel's the one who got in the best scraps anyhow!
There were some truly delicious cars at the track day. The green 260Z in the foreground looked great. The 635CSi hiding behind it is one of my favorite car designs, but I have yet to convince Janel of its inherent goodness.

|July 8, 2014 - High speed track testing.|
The recent track test at the local track was fun, but the car felt a bit like a caged animal. So I trekked out to High Plains Raceway to run with the Z Car Club of Colorado. These guys always put on a smoothly run day, with the opportunity for lots and lots of track time. I had new H compound brake pads and was ready.
How was it? Spectacular. I had a ridiculous amount of fun. The first session was one a mismatched set of tires, RA1s on three corners and a Nitto NT01 on the other. The Nitto wasn't working as well as the Toyos so the car had uneven handling left and right.
I then swapped on a set of new Toyo RRs on 9" wheels. Wow, what a difference. The chassis now had the grip to match the power, and I was able to go into full rampage mode. The chassis setup was perfect and I was able to just drive. I spent the rest of the day chasing down a variety of cars, including another LS3-powered Miata. The one car I never got to play with was a Viper with race rubber - he started one session right behind me, but pulled off after a single lap. Top speed was about 135 mph into a headwind. At the end of that straight there was a fairly intense braking zone which had me hanging off the harnesses and giggling.
Unfortunately, the car wasn't perfect. The speed and the braking zones (five major braking events per lap) meant I was putting a lot of heat into the brakes, and the fluid started to boil. I was using ATE Super Blue which is pretty good stuff, so I'm going to take a look at improving the ducting further and run something that runs a bit hotter. I could manage the heat in the brakes by being a bit cautious on braking. The coolant temperature was good - even on the very hot day and running for 30 minutes, I never got into a problem zone.
At the end of the day, I bailed early. This group starts combining run groups near the end of the day and extends the length, which meant that I had the chance to run for a full hour with a bunch of poor B, C and D drivers getting blown into the weeds by the Targa Miata. With the brakes soft, I decided there was nothing to be gained so I packed up after the end of the regular sessions. Still, it was a good day. So much fun.
