Does living in a hotter climate significantly effect the cooling capability of the stock WRX intercooler. I've seen a number of posts where people say the stock unit is good up to 300 whp, but does that number decrease in a hotter climate?
I live in Texas and we spend a large part of the year above 90F and even a few months in the 100's. Will this have an effect? Will I hit a wall lower than 300whp on the stock TMIC?
Along the same lines, will a turbo heat shield help? Or is that completely unrelated?
I've done a number of searches on this and can't find a definitive answer.
