Hi! Robert
Some time ago you published this message below ....about intercoolers.
Have you flown with it yet? What intake drop in temperature is to be
expected / and does it therefore promote the increased likelihood of
carb ice?
I am just changing over engines from a Jabiru 3300 to a Rotax 914 !
since I had a big insurance pay out for repairs due to a nose wheel
departing.
Best regards
Bob Harrison G-PTAG trike Kit 337 600 hours with the jabiru.

Maybe you'll be interested to know that our 914 intercooler was designed
by Gerhard Schruf to our specs, and we've been flying for two years with it.
The charge air temp drop is about 25°C in winter and 20°C in summer
(ground OAT 37°C). Calculated cruise efficiency is about 60%.
Concerning carb ice, our engine is tightly cowled, and the carbs usually
run at 40-50 °C, measured at the aft of the right float-bowl. We never
experienced any ice related trouble, even flying under heavy rain.
I made two cooling airscoops to direct some cold air onto the carbs.
Some pictures of our cowling can be seen at
http://contrails.free.fr/diap/phpslideshow.php?directory=diapo_capot_if
Our setup includes a correct diffuser and ram air inlet, and a good
nozzle exhaust, with no cooling air leaks nor obstructions.
Of course our aircraft is not a Europa, but this may be of interest as a
comparison. The empty weight and performance are about the same.
FWIW,
Regards,

Mr. Harrison,
What prompted the switch from a Jab to a Rotax?

Hi! Joe Russell
I have tried to reply off forum to your question but your spam control
has me "blacklisted" ?
If you make a message to me direct (off forum) advising your status,
interests and reasons for needing my decision, I'd be interested to make
a reply, but not on forum.
Hopefully you will understand my position?
Best regards
Bob Harrison. G-PTAG

Hi! Joe Russell and Creighton Smith
I have replied to your requests for information and would like you to
confirm receipt since I am still getting "blacklisted messages"?

All-
We have a Europa intercooler manufactured by Bell Intercoolers that we have decided not to integrate with our Rotax 914 research project (we are using a different version also manufactured by Bell). We are willing to part with our intercooler for half price (150 USD) plus shipping. First come first serve.
