Sample Power Data

Just to give you an idea of what can be achieved in the real world, we have used the same computer modelling techniques that have worked so well in our development of performance packages for the TVR family of engines, to yield power graphs for both the standard and modified Cologne V6, plus the Cosworth.

standard Cologne power graph

Compare this generated power curve and BHP/torque data with that quoted by Ford in its car brochures for the years 1990 through to 1992.

The above power outputs are for an Ultimax-based V6 Cologne. Note the torque spread achieved by the stroker crank conversion.

standard Cosworth V6 power graph

These are the baseline power levels for the Cosworth V6 in standard trim. Interestingly, this engine was only ever offered in the Granada and Scorpio V6 saloons, hatchbacks and estates - mated to an automatic transmission, with no manual 'box as a listed option. Though the Cologne V6 was dropped from the Scorpio line with the arrival of the 2.3 litre DOHC balancer-shaft four, the Cosworth remained in the range a while longer.

Again, compared to the standard Ford specification of this engine, you can see how the Ultimax long stroke crank bodily shifts the torque curve upwards, as well as pushing the BHP peak beyond 300, which only starts to fall off after 6000 rpm - a full 1000 rpm higher than the 'factory' trim Cosworth.

power graph for full race Cosworth 3.5 litre
And now for the big one....a full race 3.5 litre Cosworth with all the trimmings (well, almost all...). With this configuration, the power curve just keeps on steadily climbing all the way up to 8000 rpm. The torque curve is also largely flat, and stays on or above the 300 lb-ft mark from 4000 rpm up to the engine's notional top end of 8000.
