Post Advanced Aero Naca Scoop

Has anyone installed an Advanced Aero Naca scoop with a 3" scat tube on the left side of the lower cowling? The oil cooler is presently getting air from the back of the SJ plenum. The oil cooling appears to be insufficient for OAT = or above 90F. In addition cylinder #4 CHT is 30F higher than on cylinder#3. Any other suggestion ?

Default Yes and No

3" isn't going to be big enough. Been there done it. I built my own NACA duct for the oil cooler with 4" Scat going to it. If you want to see pics, do a search under my user name under speed mods, cooling, etc. Bunch of pictures to look at.
