How important is it to heat wrap the DP. From a spooling stand point I think it would be irrelevant. I heard that can cause rust. Need opinions based on experience here.

 

Not sure if it helps spooling the turbo, should help the overall temps in the engine bay is what I'd figure and if the DP is stainless rust shouldn't be an issue. I know of people that have their SS DP wrapped and have zero rust problems.
