BROOKLANDS TEST - NOV.14TH. 1925. X8770

Preliminary results.

These tests were carried out on a high compression (5.2 : 1) Phantom short chassis fitted with a Barker sports type body. The car was fitted with a 17-tooth axle to ensure that it should not be under-geared.

The total weight of the car equipped for the tests and carrying two passengers was 2.45 tons.

Though of a sporting appearance, the Barker body did not prove to be a marked improvement for speedwork. Actually we should say that it increased the max. speed of the car by about 3 or 4 m.p.h. over a standard body. The main feature of the body was its length, it being exceptionally short. This proved to be rather a disadvantage as there was insufficient weight over the rear mxxxxx axle to prevent wheel spin at high speeds. Possibly the spare wheels carried at the back would give the required result.

On the whole, the car held the track well with shock absorbers tightened up, the steering was very good with noticeable absence of shocks even at the highest speeds, there was no sign of wheel wobble.
