I'm not sure how/why people can say turbo is a better alternative in cold weather, has anyone heard or experienced boost creep/spike during cold weather? it's no fun
I vote for Rotrex SC kits (KW or JR) simply because boost is naturally limited by the pulley size so overboost is not an issue and they don't produce huge amount of TQs in low RPMs (meaning less load on our engines)..
