104 bhp was the figure advertised by the factory.

The actual increase may have been even more than 44 bhp, since car
manufacturers typically inflate their HP ratings. In order to know for
sure we would need before and after figures measured on the same
dynamometer.
Even so, a 44 bhp increase isn't really all that dramatic. The stock TR
wet-liner four isn't very highly tuned, so there is lots of room for
improvement.
