During a chat with like-minded individuals ( i.e. timewasting on the net ) I came across this Saab guy
One of the 'mods' he proposes is to bypass the coolant flow from the intake manifold.
Bit obvious when you look at it, and I wonder how on earth did I miss that? It's always been at the back of my mind, but never really did anything about it.
This is a standard feature on many engine designs, trying to keep the inlet manifold warm for better atomisation later on.
Especially useful in cold winter short runs.
Of course turbos running high boost in the summer, need this extra heat like we need a hole in the head. (More potential material for my site I'm afraid )
Has anyone here ever experimented with bypassing these pipes?
