|July 11, 2012 - A new toy showed up.|
I've been thinking about doing some more aero investigation. There are a number of things that could be addressed, such as a smoother underbody. I've already made a few steps in that direction of course. But I've also been toying with the idea of a wing. There's no question that they work.
I've been working with a metal fabricator around the idea of building my own wing from scratch. I also have an HPM wing that was previously used in World Challenge racing. But there's a particular option that's available right now that kept drawing me back.
Back when NASCAR introduced the Car of Tomorrow, the cars had a wing on the back. This was fine (well, not according to the traditionalists, but let's ignore them) until it was discovered that they'd generate lift when the cars starting going backwards at high speed, which is something that NASCARs do. So all the Car of Tomorrow wings were torn off and replaced with spoilers. Where did they go? Where old race parts go, into the used market. You can buy a nicely designed carbon fiber wing with interchangeable end plates for under $500. New, they were over $3000.
It's a big boy. Not something for a car that's low on power. But it should be fairly effective. The biggest challenge is going to be figuring out how to mount it - the hood pins on the trunk are in just the wrong place. But I'll think of something. I've got a few ideas. I'm also going to do some research to figure out where the best place to put it will be.
The wing investigation won't happen right away, though. The Flyin' Miata Summer Camp is coming up in three weeks, and I'm going to revert the car back to Targa specification for the Racing The Rock premiere. I also have three days to give joy rides at the local track, that should help burn up the R1R tires! Once that's all done, I'll go back to track spec.

|August 14, 2012 - There was a big V8 Miata meet at the Summer Camp.|
Zach took this shot and posted it to Autoblog. 4500 hp spread amongst 11 V8 Miatas. There are also are two more V8s to be hiding under covers in the back. Zach also covered the rest of the Summer Camp and captured yours truly blathering on about V8 Miatas. It happens a lot.
Autoblog also posted about the DVD. So did Hooniverse.

|August 3, 2014 - FM Summer camp track time!|
This is a tough event for the Targa Miata. Two days of double sessions, giving rides to FM customers in brutal heat. I figure I did over 100 hard laps of the track in two days. Everything worked well. Despite the heat and the short, tight track, the car ran at normal temperatures. I wasn't taking it terribly easy on the brakes, and they also dealt well with the heat.
The blue car in this awesome picture by Travis Ingram is Elvis, another V8 car. It's got AFCO suspension with a bit less spring rate and the same basic tire setup that I do - and it provided a very dramatic visual example of how effective the aero is on the long sweeper as I came rampaging up on his rear bumper with a very high closing speed. Quite exciting for the passenger in Elvis as he saw me bearing down, too. There was also a great example of the wing's wake when a drone above the track got thrown around by the rooster tail from the car - I'll try to get the video of that.
I found the car to be pushing a bit on the tight track with the setup that had been working so well at High Plains a few weeks ago. There was no time for tuning, so I just drove around it after softening the front sway bar. I've found the car is fastest with a little bit of aero-induced understeer on the fast sweeper, but it was a bit more than I prefer. Next time, I'll try playing with tire pressures although they were right at my target. Even after about 150 laps of this track and the recent High Plains track day, the tires are looking good. The Toyo RR is my new favorite track day tire.
There was one small area of concern. At the end of the last session, I had an odd noise in the steering. A clunk at a specific point of steering angle. Fearing the worst, I got under the car - and found that a motor mount heat shield had moved out of place and was making contact with a bolt on the steering column. Well, that's an easy fix! Whew.
