I wouldn't be too worried, The Phazer radiator got plugged because its HOT and the snow instantly turns to sticky slush when it hits it. I don't really see the intercooler even getting warm enough to "slushify" the snow, the turbo should only be raising ambient around 20-25*f at the boost levels this mill is probably pushing. With that said, even with the intercooler plugged it won't effect power output that much since we are only talking about a 20*f temperature difference which is MAYBE a 2% loss of HP.
Not talking about icing / slushified snow but rather inability of air to flow across the cooler. Not to harp but the charge air cooler plays a very important role in development of power for turbo charged engines - especially in high strung "electronic" engines in which many variables are combined to develop the fuel map. Not such a big issue with mechanically controlled controlled engines but much is being made of the sidewinder's ECM being able to monitor / control so much based on engine sensor data. Once one item is out of the set parameter then all goes to pot pretty quickly i.e. less fuel injected .... Looks like a great engine but I will be surprised if this forum isn't ablaze in a year's time with a bunch of owners looking for a "solution" to allow air to flow freely over the cooler.
As for the phazers I've had 5 to date and all had similar issue of snow blocking the rad in powder conditions + in real good pow the air box would also tend to choke off and cause the engine to stall once off the throttle ... wait a few minutes for the engine heat to thaw the air box and it would fire up again. Not an issue on hard pack but definitely an issue in powder when running hard.
