So what is the limiting factor here then? Is it impossible (fiendishly complex) to cast equal-length runner manifolds?
Expansion and contraction of the metals as I understand it, and yes - I imagine it is.
The manifolds are several pounds of very hot metal. The turbo timer expects to cool only the turbo bearings, while the manifold radiates heat into the engine bay. If the manifold can't radiate heat, it can only conduct it...much of it going into the turbos over the course of a long time I'm sure you can see the problem -- safe turbo cooldown times will be much longer than before, and the turbo timers won't expect it.
So is the engine block(where I think much of the heat would soak to), I understand your point but I really don't think that slow bleed off after a proper cool down will be a big deal at all.
Yes, I am thinking of swain coat, but on the inside of the manis, not just the outside. As I recall, there is a thermal barrier swain coat (put it inside) and a coating that helps heat to radiate quickly (put that outside).
Here is the information. I believe I have the white lighting coat on my manifolds, same as the Sport compact car project Z. I don't see anything about an internal coat(nor did I see one in my manifolds)...
