The spacer is what I've been waiting on to complete my anti heat soak protocol for the intake manifold. Got on the list as soon as I saw this on FB! Been waiting months since I saw a cad drawing of it.
Some 1/2 wall heater/HVAC pipe insulation for 1" pipe, wrapped in foil tape.
This coolant outlet pipe sees highest coolant temperatures in our engine. Our aluminum intake manifold surrounds this pipe within an inch on all sides.
The manifold spacer should reduce heat transfer from the cylinder head. I can't wait to get out all of my tc's and temperature capture equipment to see what the difference is with both of these mods in place.
200°f+ temps radiating off this pipe directly on to our aluminum heatsink of a manifold. At idle, on a warm day, 170°f IAT2 temps aren't uncommon after idling for 5mins or so.
High IAT2 temps definitely effect off the line performance.

Well, gotta give you full credit for this, but I went ahead and did this on top of the ceramic coating...have I gone tooo faaaarrrr???? LOL...thank you for the idea. I kinda put a spin on it as I had some of that gold foil tape laying around and just had to buy some of the insulation (gotta get the rubber, not the foam, the foam can not stand up to the heat and will melt).
Now just waiting on the intake to come back from porting.
