I came across a new Rotax 618 engine the other day at a good price. I
also am going to be rebuilding my 582. Is the bottom end of a 618 the
same as that on a 582? Please don't guess.

Sorry Hugh, that last post had nothing to do with you, or Noel for that
matter. I hit the send button before finishing editing.

Hi all,
I was wondering if there are any 914 drivers out there that some times operate
in the 12,000~18,000 feet range.
I am using Penzoil Motor Cycle oil and I suspect that it foams a bit. I was told
the Valvoline Dura blend works better at these altitudes.
Any first hand experience would be appreciated.
Thanks, Paul

Hi Bob
Here is some info on Evans as it pertains to my decision to use it on 914
Monowheel Europa:
http://contrails.free.fr/engine_burn_baby_burn_en.php
Evans will run a little hotter than 50/50, but don't think it will be 40F
(I have the general rise for Rotax powered Europas at hangar if you need).
According to John Hurst (was Europa USA in Lakeland) think it was 3 to
3500RPM and full course into wind yielded best cooling on ground for
Monowheel Europa.
Option for extended ground operations, shoot some water from car
windshield wiper pump onto radiator, could always inject into motor to
help on climb out if not used on ground! I would use distilled water. Kim
Prout said someone by him on West coast did this with good success.
Supposedly this is good coating for 914 exhausts:
http://www.performancecoatings.com/
I am going to coat my 914 exhaust (to keep some heat out of cowl), if you
disassembled turbo you could do that too, but I am not, just going to wrap
with blanket from Aircraft Spruce. The same company sells a heat
dissipating coating I am going to have them do my 914 water radiator.
I forget but think you changed intake on your cowl, you could tuft it and
see what RPM and pitch with different wind angles yields best results. I
will mention it, but am pretty certain you have radiators well sealed so
any air is going through them instead of around.
I have no practical experience, but try pulling enricher and see if it
allows you to run cooler??

Hi Paul,
Down on this list somewhere is a post about 20 different oils. Yes some do foam
a lot more than others. This is why Rotax made the oil level in the oil tank
higher a few years back. If you are using 91 Octane fuel the majority of the time
I would recommend Amsoil full synthetic, either
10-40 or 20-50 motorcycle oil. It is the least foaming of all the oils, even Mobile
1.
If you are flying at 10K or higher then I hope you use 100LL as it is more stable
and less volatile at high altitude. Then you need a semi synthetic to suspend
the lead in 100LL. Golden Spectro 4 is another good choice for the anti-foaming.Here
is the link to read about oils and what their properties are. You may
have an oil you like, but this just helps in understanding what additives do
and what oils seem to do better.
