Mines a centrifugal not a roots or twin screw style but I had a need to daily it a few weeks back for a week and a half... No issues at all in the rain, cool (actually hit 46 here during that week in the morning) and heat. I obviously monitor it closely in traffic and 90 degree days but it rolls along fine and treated me perfectly... Now for that week other than one or two spirited throttle pokes I drove it like a Ford escort from the 90's and went easy... I needed the car and preferred not breaking an axle or dropping a transmission that week.
Top Mount blowers are typically even easier to drive for daily duty than centrifugal ones as the power is a bit more linear... I can't speak for the OP but if his tune is right then he should have no issues daily driving.
