My bad, I grabbed the wrong car, posted more than one and mixed them up somehow.

The person's Facebook page is called "Amzel Ltd." and he worked on the Lola as well as the red ink wash car (Nimrod Aston Martin) apparently.

Part 1 - Nimrod Aston Martin

My first solo project in motorsport was the Aston Martin Nimrod Group C. I left Lola Cars to join Nimrod in 1982, with the concept of a Group C car with a full composite chassis having been growing in my mind for what seemed like years. Nimrod offered me the opportunity to make it real.

Here are some photos of the (very basic, by today's standards) wind-tunnel model which give an idea of the concept. Some pictures show the windscreen painted in. There were also side windows, which aren't painted, but which can be seen moulded in in some shots. Part of the rationale for the body shape was to eliminate the A-pillar, which, I felt, in a composite chassis, with no steel roll cage, would be a structural weak zone. I have some photos of the chassis, but very under-exposed. However, I may put them up here.

Another reason for the body shape was to clean the upper body airflow, and eliminate the cross-flow and separation I'd seen on other sportscars. I was pleased with the flo-viz that can be seen on the pictures. The little wind tunnel work we did (funding was tight) was done at MIRA, in the fixed-floor quarter-scale tunnel.

I and my design team (actually, I was the whole design team) were very ambitious. The gearbox was stock Hewland VG, but the bellhousing was a mix of cast magnesium and carbon fibre.

More later....

More on the Nimrod aero. The gap between the basic body shape and the base of the rear half of the front fender "bubble", which is visible in some of these photos, is not poor model-making, it was there to vent the front wheelarches. My alternative to louvres.






EDIT:
I signed into Facebook to view more of this person's work, and more history and descriptions showed up. If you can get over what ever Facebook phobia or Mark Zuckerberg dislike you have it could be worth the effort. My issues with FB is that I feel drained after reading everyone's personal lives and attempts to intruded upon my own. I don't care to keep up, my old friends and family "interests" just don't line up with my own very often. The chatter in some of the vehicle or hobby pages can be good, but unless you are trying to buy or fix something it is of fleeting interest. And unlike a forum I have difficulties locating old posts or thread topics, and don't know how to pick up where I left off - very frustrating.

Red ink wash = Flo-viz
