SUNBEAM TO IMP CONVERSIONS MODIFIED FOR FAST ROAD

The same spec as for IMP fast road on page 13 using as above Sunbeam complete engine conversions

i.e. 15%-20% increase of power over standard, while still retaining relatively lower speed torque, although usable in traffic conditions but ideally suited for the open road and some minor competition events.

The same spec as for IMP Comp/Clubman on page 13 using as above Sunbeam complete engine conversions

i.e. 50% extra power over standard, a seriously modified engine intended to be used in competition events i.e. Sprint/Hillclimb/Rallying etc (in conjunction with twin 40 carbs) and yet still tractable enough if required for the open road.

SUNBEAM B1 998cc/1040cc Competition/Clubman Engine (from) 2960.00

Estimated output 988cc on twin 40 Weber carbs: 92bhp @ 6800 rpm
* (recommended max 7500 rpm)
* The advantage of using the stronger B1 block assembly is its rigidity, block strengthening would only be necessary in race state of tune.
