Our Workz - Triumph Dolomite Sprint Group 1 Race Car Build 2021

We wanted to build a period race car, after much deliberation it had to be a Coventry car and a previous championship winner.

The 1975 British Touring Car Championship winner was Andy Rouse in a Dolomite Sprint, so that was the car to build. We looked at a few but the body was important and good ones are very hard to find. Then we found it, a 1975 relatively good condition, British Racing Green (colour 75) car. The interior was originally brown but had been changed to black. So, we had a start.............. 

The car was completely striped, glass, doors, every nut and bolt. Any rot (not too much) was cut out and new plate welded in. The sunroof was removed and new plate welded in there too. The body was stich/seam welded. The body was then fully prepared, primed and painted. The Safety Devices Homologated roll cage was trial fitted and the required base plates also welded into position. The underside was painted with "Cobra" truck liner.

Whilst the body was being painted we started on the drive train elements. Engine, gearbox, competition overdrive, uprated diif, Gripper LSD and competition rear brake shoes. New Hardy Spicer's to the prop. All engine rotating components balanced individually and together. Twin plate race clutch, lightweight flywheel and concentric slave clutch.  The head has been cc'ed to within 0.5 cc, polished and port matched to both the exhaust manifold and twin Weber 48 DCOE's and manifold. New Gaz adjustable suspension was fitted to the rear axle and front subframe. The whole suspension is SuperFlex polybushed.

The big question was what should it look like? We decided on a Group 1 "Works" car recreation, similar to Andy Rouse and Steve Thompson's 1976 (Broadspeed) cars, Tony Dron's 1977 car and the Belgian, Julien Vernaeve works car (as attached image car 26). There was a "Works" car sold recently in the same colours (as attached image car 20). 

This is the livery we have decided to use.

The car is now well on the way and is only a few weeks off finishing.  Note, new vinyl roof - tricky little job but looks great with the "French Seams" either side. It's getting new everything. Some of the engine work information will remain with us for the time-being. Looking forward to testing and getting it out with the Classic Touring Car Racing Club, the club number will be 20.

Full strip down and rebuild of a 1975 TR6 (125 hp) in Pimento Red, body striped and welded where necessary, prepared and painted. Engine, gearbox, overdrive, diff recondition, new interior, MX5 seats and mohair roof. We collected the car and it was not running very well. the paint was very faded and the original interior was quite poor. The car had been in one families ownership for many years and there was quite a bit of nostalgia and pleasant memories, so the brief was to bring it back to its former glory.
