> Hi Group Has anyone flying with Rotax Cooling Air Baffle modified the internal
flow to give cylinders #3 and #4 a little more flow compared to the front two
cylinders? How about with a 914 even giving #3 a little more flow compared to
#4? This coming week going to test mine with a leaf blower. Thx. Ron

Hello Ron and all,
We installed the Rotax air baffle on our 914 and made some measurements
at the time.
Here are some considerations :
With adequate sealing around the baffle and some pressure recovery
(expanding inlet), all 4 cylinders get enough cooling air.
Only the #1 gets some extra blast from the "bizarre" Rotax inlet.
Due to liquid cooling, the cylinder heads are good "temperature sources"
and the cylinder temps never exceeded 100/120 C.
FWIW,

Best regards
