Aluminum heads

  • Thanks. The coolant stabilizing the rate of which heat can dissipate from the aluminum is something I hadn't though about.
  • I think the concept of what I spoke of in Jpars thread still has some reality, but I also agree with your post in detonation and especially the coolant stabilizing the rate of which heat is able to leave the head.
  • I will say the way I thought of it is "not all wrong, not all right either" if that makes sense.
Again, I like to open my bean and gather more, it just has to make sense to me. The coolant part in your explanation makes perfect sense in making what I believed not irrelevant, but less relevant


Certainly you are not all wrong. If you are loading an engine to detonation in a steady state, where everything is stabilized, then there is some help getting the heat out of the head quicker...IF the cooling system can deal with it.

We are usually discussing engine in transient response and not steady state so that makes a big difference.
