track porting
I've wondered if porting would help the MC '18 with it's overheating. A friend of mine tried it on his 174 turbo with the idea of keeping the temps down in marginal conditions. Lowered temps significantly, varied from day to day depending on conditions. Also worked in deeper snow. He added 3 holes approximately every 12". I'm going to talk to him some more about it tomorrow. Not sure if there is a downside to this or not. A friend of his told him about how it improved his "17 quite a bit, so he tried it on his turbo with 3" lugs. Debating whether to give it a try. Worked on the '17 so ought to improve my '18. He said one trick is to keep the holes on the smaller side because some people have used pretty big holes and track starts tearing. I never measured hole size but looked to be about 1" to 1/8".
