approximately 66 horsepower per liter, whereas petitioner's
objective was to increase the engine's horsepower to a range of
100 to 118 horsepower per liter, for a total horsepower in excess
of 500 for a 5-liter engine.
Petitioner began working on his concept around 1984,
initially on a Porsche 928 S4 two-valve engine. In late 1990,
petitioner decided to intensify his efforts to develop the engine
modifications. After consultations with other mechanics who were
familiar with the Porsche engine, it was suggested to petitioner
that his concept would be more suitable for a four-valve Porsche
engine rather than the two-valve engine.
In March 1991, petitioner purchased a damaged Porsche 928
S4, four-valve engine, on which he would make the modifications
to enhance the engine. Later, in 1991, petitioner enlisted other
individuals to participate in the venture. Under the agreement
with his partners, the enhancement of the engine remained an
activity of petitioner, and his partners were to develop and
