Was it used for performance gain?

The early engines showed little performance gain: the steam pressure was too low, interconnecting pipes were of small diameter and the condenser ineffective.

On the other hand, a stronger family can be reduced to a weaker one, as long as a performance gain can be reached.

Also, the speed of business has accelerated to the point where a performance gain of nanoseconds can make a difference in some industries.

However, the 1992 season resulted in no real performance gain despite the additional power, suggesting the chassis was at fault.
