Subject: [FlyRotary] IVO Prop Info. (Have
you checked this out Mike?)
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...
