Hello again! First time in, what, a year? On the forums, at least.
Here are some WSR cars I made. I’ve been on an Australian-car binge recently, and of course inspirations such as Holden Dealer Team and Holden Special Vehicles were top tier. Let’s go through 3 of the most iconic ones;
1985-86 Serpent Jubilant SK WSR Group A
Built by Serpent and modified by WSR, the Jubilant SK Group A was designed to satisfy Group A homologation regulations. As a result, the exterior of the car was extensively redesigned with aerodynamics in mind. It was produced between 1985 and 1986, in a run of 500 units to satisfy the homologation for Group A racing in Australia. Though extensively modified by WSR, the car carried Serpent badges because of regulations, and was subsequently mostly referred to as a Serpent.
The WSR Group A features a half-closed front grille, leaving only the bottom open strip for improved airflow over the cabin. Additionally, the bumper vent was made larger, and the hood received a large bulge. Furthermore, the car’s stance was widened somewhat and fitted with a side skirt kit as well as a large wing encompassing the entire trunk area. Finally, rear louvers were fitted. The car was only available in blue, yellow and red, though most units produced were painted blue to imitate the race cars.
The engine was a heavily modified 5.9 liter V8, fitted with a Wulff Twin Turbo system. It was rated as producing 240 horsepower - though higher figures have been reported from dyno tests. It was available with a 5-spd manual transmission, and a 4-spd automatic was available as an option.
1988-89 Serpent Jubilant SZ WSR Group A "Callahan"
Group A regulations at the time stated that 500 road-going units needed to be built to qualify for homologation, so WSR was contracted by Serpent to modify and produce the car. As a result, similarly to the previous SK WSR, it carried Serpent badges, though it was technically a WSR. Produced by Serpent and modified by WSR between 1988 and 1989, a total of 550 units were built.
The bodywork of the SZ Group A was heavily altered to improve aerodynamics and downforce. An entirely new body kit was developed for the car, specifically to minimize air resistance and to maximize airflow. The body kit was made mostly out of plastic and fiberglass. Covered foglights were added to the bumper, and a single-slit grille was fitted to improve engine cooling. It was given widebody arches and a door and sideskirt kit which improved general airflow. Finally, a large rear wing was added to assist rear downforce.
The engine was further modified from the SK Group A, mainly focusing on strenghening components while also fitting larger turbochargers which produced a distinct notable fluttering. WSR produced a total of 550 units of the SZ Group A. The original run of 500 was required and produced in 1988, while another 50 were produced into the beginning of 1989 due to popular demand.
1995-97 Serpent WSR-GT
While accounts vary, sources indicate the WSR-GT was built from a batch of would-be Serpent Jubilant taxi cabs which never entered service. As such, WSR was able to acquire the vehicles at a large discount. Between 1995 and 1997, a total of one hundred WSR-GTs were produced, 25 fitted with the optional “R” package which increased engine power. The model was only available painted in “Hella Yella”, though some later units were reportedly custom ordered in other colors at additional cost.
The WSR-GTs engine is a heavily modified 5.8L Serpent V8 engine, developed specifically for the Australian market. The engine’s internals have been modified to include forged cylinders, heightened compression, an increased cam profile and an extensively reworked fuel delivery system featuring multi-point fuel injection. This leads to a power output of approx. 330 horsepower, or 375 for the “R”. The bodywork has been modified in tandem with the engine, most notably the inclusion of a large rear spoiler. Side skirts have also been fitted to improve aerodynamics, and the front bumper intakes have been narrowed and flushed to provide more optimal airflow.
Though the WSR-GT never had a contemporary Group A racer, as Gr.A ended in 1993, it was still a tribute towards the Group A-esque performance levels normal road cars wouldn’t dare achieve.
Well, that’s all for now. See you soon.
Maybe.
