Hello Clyde,
This topic comes up again and again. The Pulsar 1 with wood wings has a
gross weight of 900 lb, vs 1060 lb for the Pulsar XP. If you installed a
Rotax 912 without any modifications, you would turn it into a single
seater.
I have done the analysis and documentation to modify the Pulsar 1 structure
to XP weight and speed limits, but that includes adding plies to the
fuselage skin on the inside, which would be very difficult to impossible
with the skin halves already bonded. It also means highly modifying the
wings for wing tanks instead of a fuselage tank, and probably increasing
the spar structure, although I don't know what the dimensions are of the
composite spars you have. They would have to be measured and either
reinforced or you may need to build new spars.
All in all, it probably doubles the amount of work over building the Pulsar
as the model it was designed, plus the extra engineering work can get
expensive.
