*NB:
Power output figures are for a standard engine as
fitted to the Dolomite. When fitted to the Latham
F2 the fan is removed and the exhaust system replaced
by a less restrictive type. These modifications
alone should give an increase of some 10-15bhp. |

NB:
Performance figures are estimated for cars fitted
with standard engine and manual overdrive gearbox.
*In
practice, these figures proved to be very conservative,
and a Sprint engined F2 was easily capable of
higher speeds than this, with an 1850 powered
car matching the figures quoted here
