REFLECTOR: Cont'd oil temp problems

[Scott Derrick]

If this is an updraft configuration and your probes are on the bottom of 
the cylinders you are getting a cooler CHT than your cylinders are 
actually running at.  If updraft with lower probes your temps should be 
in the low 300's, in the summer.

I ran a IO360 200HP in an updraft STD RG  for 450 hours. Once I got the 
baffling  tight,  got the standard nose oil cooler set up right and ran 
LOP, my CHT's ran 330 and oil temp  ran 200. 

You don't need a 2nd cooler. One will do the job if everything else is 
done correctly.

I would be very reluctant to sacrifice the ram scoop to run an unneeded 
oil cooler. You will be sacrificing both power and weight.
