Increasing
the engine power from 82 HP to more than 250 HP is a very
challenging development in terms of engine modifications and not
least heath management.
Power is generating a lot of heat, and I
mean a lot of heat.
I did not take this serious enough in the
first place, with the result of having up to 60 deg C (140 deg F) at
the feet.
After many
temperature and airflow measurements on data log from road test, a
lot of airflow improvements was implemented.
The air was guided
hard through the radiator, separate intake for the intercooler,
generator and firewall. The engine oil cooler was relocated from the
front to inside the right wing with a separate air intake and extra
air to the Turbo inlet filter.
