INTERESTING! Couple of thoughts. Before you modify your inlet
openings, try putting some vanes in the plenums hung off the top. I
have not done that, but it will be my next step if I still have cooling
problems. My thought was that they would be about 1.5 inches deep and
run from the front to just forward of 5 and 6. If that doesn't do it,
you could put some deflectors on the vane to deflect more air toward the
heads. The vane worked so well in my cobra head that I think it may
help here too. The air coming into the plenums must be very turbulent
as is. My plenums are back on the plane and now on to the oil cooler.
I may have told you that I split my shark's tooth along the sides and
made the opening about 1/2 inch higher. Both that, and my cooler is
11.5 inches wide, so I have some hope for it. Also, did you add the
holes and plenum on either side of the shark's tooth to cool the oil pan
directly? I have it on mine and oil temps have been OK. I built it
this way, so I can't say that made the difference, but I remember
reading somewhere that cooling the pan directly helps. John probably
told you too that he worked around the problem by mounting the cooler
directly in the cowl. When he takes the lower cowl off, he needs to un
hook the cooler from the hockey puck. We need to open a photo sharing
site somewhere. My pictures are 5 GB each, so e-mailing them does not
work well. Any thoughts?
