This is the final set of scans of photos from my trip to the 1991 IMSA Camel GT at Del Mar. These are just a few shots taken in the paddock. I think there was a nominal extra charge for access to the paddock where you could see the teams work on the cars between sessions. We had Super Photo passes which also included access to the working pit lane, but one intimidating walk through was enough to convince us to stay out of the way. I was a junior in high school at the time. Camera was a Canon A-1 with 35-70mm and 70-210mm lenses. (Most links go to Wikipedia pages.)
The top photo is the Ross Brawn-designed, Cosworth V8-powered Jaguar XJR-14.
Here's the Tom Walkinshaw Racing crew pushing an XJR-14 with it's high-downforce front wing. The deep dish gold mesh wheels are so perfectly 1991!
Here's the Nissan NPT-91 glimpsed through its own mirror.
Dan Gurney's All American Racers Toyota Eagle MkIII would dominate the final two seasons of IMSA GTP racing. The engine was a 2.1-liter, 4-cylinder producing up to 750hp. This front view shows the "integral front diffuser in the nose to stabilize underbody airflow" and balance the downforce generated by the giant rear wing. That single gaping catfish mouth fed "midmounted water, water-to-oil and turbo intercooler radiators."
Here are the noses of the Comptech Spice-Acura Camel Lights prototypes. Along with a glimpse of the requisite multi-piece BBS mesh wheels with gold centers.
And finally, a look down a row of prototypes.
