Scott, My coupe also runs on the cool side in the winter. The other day it was 15 degrees and the oil only warmed to 125 - 130 degrees. I have seen coupes with duct tape covering part of the intake area in front of the cylinders. I don't know how much this helps. I don't care to have a loose piece of duct tape melting on a cylinder if it were to come loose. My solution has been to cover the air intake and fly it at 140 degrees or less. (I have heard comments that coupe owners in the west and mid-west are addicted to duct tape :) ) Mike @ C35
