Ok let's say its a hot summers day and your on some little twisties, going uphill, 2nd gear, national speed limit. You accelerate, go round a corner, accelerate, go round a corner, accelerate, go round a corner ... And so on
Haven't broke the speed limit once, take a lot at your exhaust manifold and take a feel at your inlet.
With a smic the intercooler will be red hot with the fmic it won't... Simple as tht
There is nothing wrong with over engineering.
Under engineering on the other hand is a bodge and bad for the car.
Full stop
