Eggenfellner Aircraft is currently developing a supercharger kit for their
engines. This would allow the RV7 to develop 165 HP up to 12000 feet.

Can you please tell us when we can expect some real world climb and
cruise performance figures flying RV-XX with your Eggenfellner
(non-supercharged) Subaru engine? Also, for some of us who are not so
engine savy, what should be our expectations regarding RV performance
with the Eggenfellner Subaru RV configuration and the supercharger.
Please, if you could, compare the Lycoming 160hp and 180hp engines
with your supercharged and non-supercharged Subarus so that we can
have a proper appreciation for your comments regarding a supercharged
Eggenfellner Subaru engine.
Most of us who are building side by side planes (6,7,9) are very
interested in good quality, fast-flying cross country aircraft.
Aerobatics is probably not number one on our lists (especially at
12000 ft). Therefore, a 165hp supercharged Subaru engine climbing and
performing as good or better up to and at 12000 ft than a 180hp
Lycoming would be very interesting!

THIS IS EXACTLY THE KIND OF QUESTION WORTH ASKING AND SHOW GOOD UNDERSTANDING
OF THE TOTAL ISSUE. NAMELY THAT HP ALONE IS NOT AN ACCURATE INDICATION OF AN
AIRCRAFT'S PERFORMANCE. I WANT TO ANSWER YOUR QUESTIONS IN DETAIL AND
THEREFORE WILL DIVIDE IT INTO SEVERAL REPLIES, STARTING THIS EVENING.

Jan,
This is in response to the letter below. Richard said
he talk with you about RV builders being bargain
shoppers and not wanting a firewall forward package. I
disagree. I think what drives RV builders to be
bargain shoppers is the fact that a new Lycoming cost
20 grand plus prop,plus accessories,plus.... and the
list goes on and on! By offering a COMPLETE firewall
forward kit you can ensure consistent performance as
well as giving peace of mind installing a (heaven
forbid)non-aircraft engine. It will take some time for
non-believers to see the light of a new age in general
aviation. It is truly a shame that the general
aviation professionals want to choke any new
technology rather than embrace it. Imagine the
possibilities and true steps forward in GA if we all
would just look past the nose on our face.
Blue skies & tailwinds,
Scott R Luckman
LOWER INITIAL COST:
Jan, we had our local EAA meeting last night at my
hangar and we had one of
the largest turnouts for a weekday meeting that I can
remember. There were
probably close to 25 people checking out my engine.
And all the comments were
very positive. Everyone was very impressed with the
engine, how smooth it
ran, and the quietness. I am sending one picture along
with this that shows a
few of the men checking out your engine.
We have several RV builders that wish you had a
firewall forward package for
them. They had their tape measures out last night
checking out the width and
they all felt it would fit just right for them. I know
I talked to you about
this one time and you felt RV builders were bargain
shoppers and would not be
willing to pay for a complete firewall forward
package, but I am not sure
about that. If you consider what even a used Lycoming
engine costs, then all
the time and money spent in looking and buying mounts,
baffling, exhaust,
etc., I think they would consider the package you have
attractive and a
bargain. just like I did.
I would encourage builders to take some time and add
together everything they
need in front of the firewall, all the way out to the
tip of the spinner, for
a Lycoming and also for the Subaru. The real #'s are
scary.
