Duncan Black's SP250 Restored
Specification of a standard SP250 (Source http://en.wikipedia.org/wiki/Daimler_SP250)
Duncan's car had the following modification
1. Anti-Tramp Arms on rear axle
2. MGA Rear Axle, with Limited Slip Diff
3. Engine has ported head, road/race cam specification.
Max Power 123.9 (At the flywheel) @ 5593 RPM / 102.9 MPH (Note low MPH as the car is
set-up for sprints)
Max Torque 140.8 @ 3323 RPM / 61.1 MPH
4. Aero Screen
5. Roll Bar, with side impact bars
6. Race Tank, dual petrol pump
7. No Interior, racing seat
The following pictures can show the detail that has been added, I have include some
specification of the car from the rolling road. The first shot shows the bonnet tie used and also the
Anti-Roll Bar used from a TR6. This is the same as Duncan would have used, we went for 3/4" size. Also the
tow hook in place
Next is an overhead shot of the car showing the No 4, also I converted to different mirrors.
Note racing seat has been placed, but again the original is with the car.
The next shot, shows my BARC badge. The car has been set-up for sprinting and hill
Another shot showing the car, also I placed on the side the two championship win.
I have added a SCCA Washington DC sticker from 1960's, also note the fitted system to protect
Rear of the car, showing the external charge for battery. Duncan had this fitted we just
cleaned it up. Also the view of the car tow hook can be seen.
I have added some interior shots of the car showing the side impact bar. Also note the
window was filled in and has been changed and filled.
The next shot shows the aero screen and the harness fitted with the racing seat.
Last interior shot, the dials and dash can be seen
Now the V8 engine shots, as can be seen I run open air filters to get better flow. Everything
The last one is a front view of the engine, showing the catch tank and the cut off
Before the car was completed it went to 50th year of the SP250 at Gaydon. Notice this has the
two old seats. No race seat, if it every went into historic races I would convert back. But for sprinting it
is more relaxing driving with proper head restraints. This is how the car would have looked in 1963.
The last shot is at Goodwood, just outside the house. The car got invited to attend the
annual GRRC day. The car was well received, also only around 20-30 cars got selected. So very
