The hardtop on the Miata is one of my targets for weight reduction on the Super Touring 6 Miata. During the last round of extreme weight reduction on the racecar, I did some testing to try and determine what effect, aside from an 11-lb weight reduction, running without the rear glass would have...
Getting the Super Touring 6 Miata down another 130 pounds is no simple task. In part 1, I laid out a plan of attack that I started at the most recent Nashville Superspeedway event. I brought my scales to document the weights, and although I may have looked like a maniac with a Sawzall in the...
The exo car build has become a very detailed project, and the fact that I am using it as a huge test bed only adds to the complexity. As a result, this initial fabrication phase, including the roll cage, lasted longer than anticipated. But here we are, tying up the loose ends to bring this phase to...
The NA Miata came to me with extensive front-end damage, so much so that the frame rails forward of the front struts were cut. Although I am getting closer to painting and reassembling, I must first construct a front end. I will create a tubular front bumper that ties into the front frame rails and...
Although the main roll cage is complete, a few items must be fabricated before I paint the chassis. One such item is the dashboard and switch panel. I intend to run several mechanical experiments and tests with this chassis, so I need a clean and easy way to mount several gauges. To do this, I...
Building the roll cage for the ‘ghettocet’ is easily the most time-consuming part of this build. But here we are … finally … with a custom cage built and installed by yours truly. There are a few odds and ends to add, like window net mounts and a Lexan windshield. But for...
Last year, I converted the 1.6-liter NA Spec Miata to run in the Super Touring 6 class with NASA. This power-to-weight ratio class allowed me to shed the weight of the underpowered racecar aggressively. The result was a 2230-lb racecar with the driver, a reduction of 45 lbs. from the Spec Miata...
Let’s call this intermission on the Ghettocet Miata. A time to get up, stretch our legs, and see how far we have come. Frankly, I let my imagination run wild during the roll cage build, which has taken significantly longer than anticipated.
I wanted to simplify the intake path on the Miata as soon as I converted it to Super Touring 6. After fruitless research yielded conflicting results and very little non-anecdotal data, I decided to hack my own system together. The result is the shortest intake possible while retaining the factory...
It is finally here: the fabrication portion of the exo car build. Getting to this point has been quite the process: digging up all of my old equipment and piecing together a functional fabrication space. But with all of the prep work behind me, it is time to build the roll cage. The first step is...
Mechanical tube benders need to be mounted securely to the floor for operation. Typically, a hammer drill and concrete anchors are used to secure the mount to the floor. This time, though, with the JD2 bender being converted to hydraulic, I am free to mount the bender in a mobile configuration...
I have a bit more work to do before starting the roll cage on the exo car build. One of those tasks is converting my 15-plus-year-old mechanical tube bender to hydraulics. To risk sounding like a broken record, my workspace is small and not tube-bender-friendly. I can save space by converting the...
