So it was time to check what I was doing. And, the flow through the radiator was not happening. Changes to the wing were not having exactly the results that I would expect. It's a process.ġ1/22/14 Doing a few more CFD runs, a couple things about the results bothered me. They probably weren't the first but in my mind Audi were notable for it with the LMP R8 (which was really on-top-and-then-through) and progressed to the R10 and then the rather dramatic R15.įor my part, the dp1 started the concept in my designs progressing to the D1 and now I'm looking to take it even further with the rebodied D2. The concept of taking the air THROUGH the car rather than around is not new but it works pretty well and over time more seems better. At some 16 hours per run, and being disciplined changing only one thing at a time, it's slow going but fortunately I have a computer I can dedicate to doing that and work on other things in the meantime.

As the pictures below show my initial placement of the wing was not ideal so I'm rerunning it with a different setup. In real terms it means an increase in top speed from about 165 mph for the current car with no wing (152 with) to over 185 mph for new bodywork, with a stock LS3 engine. The most striking aspect is the drag reduction versus the current design - almost half at 100 mph. In the meantime I've run some initial CFD on the new bodywork, with and without a wing. What I can say is that I'm quite excited about the possibilities. As a result I'm in some discussions that could lead to advancing it to a whole other level, as well as lead to additional models. But at the same time it's nowhere near done and there are still quite a few awkward lines, surfaces and angles.

Now I can look back at the early renderings and ask 'what was I thinking?!' - of course that's all part of the process and is as I expected. It certainly has evolved from the last post a week ago. Tinker with the bodywork design is one of them. The good part is that some of the parts take about an hour for each op so while the machine is running I can do other things. 11/19/14 Busy few days - mostly machining parts (until compressor died, then we bought a new one, then it died too and mill won't run without air).
