Mike Wills, et. al:
I have posted this info. on the list before but will do so again in case
some haven't seen it before...
These go to the Ross Farnham's site in Canada and he has a lot of
great information that documents his trials and tribulations in installing
a Subie turbo in his RV-6A. He has been flying behind a Subie with an
IVO high pitch (45-105 blades vs. low pitch of 30-90) for a number of years and
is therefore a great source to e-mail if you have questions on its' performance,
routine maintenance requirements, etc. He doesn't have a huge spinner on
his installation but uses the stock one from VAN's and can still hit 181
kts. wide open and burning a bunch of fuel...
The top link (above) discusses the IVO performance as demonstrated
in a side by side flight comparison with a similar RV w/180 hp and
Hartzell CS prop. He found that the two were very similar in most of
the profiles flown. The bottom link is the "home page" to all his
RV-6A information and I found his cooling discussions and intake / exhaust
manifold fabrication pages a
very interesting read...
