under 45 degrees water temp ? Ask DCI. I think he was trying to sort the same problem out a while back here when we had two weeks strait of freezing temps

Rob , The problem we where having here , was with steel bore motors . We found the block drain holes ,on the production blocks are in the area ,of the incoming ,cold water . This was letting cold water run directly across the two lower cylinders (5&6) , and creating a problem .

Hi Po motors ,don't have this issue .

Rick , Sorry I can't be of any help with your Nic Motors .

Rick i've run my 280 when it was down to 20 degrees let it idle alittle bit get it on plane run it for about 2 minutes under 4000 grand than hammer down i've ran my 280 atleast 10 times when it was below 32 never a problem yet but put your box at atleast 103 or higher:thumbsup:

I agree, the pistons and cylinders will expand at a much more comparable rate than a forged piston and steel bore... If You've got a water temp gauge then let that be Your friend, if the temp exiting water temp is good then let'er rip... I also agree about turning the fuel up a notch for the cold air...
