Phenolic Spacers have come up a number of times on this Site but no one has really explored them.
I recently read an article on Auto Speed (here is the link http://autospeed.com:80/cms/A_110474/article.html ) which makes interesting reading.
I remember reading a thread where the member said he couldn't put his hand on top of the upper plenum after a drive due to the heat soak.
As I'm building a supercharged engine and can't fit an intercooler every degree I can keep out of the maniflod the better.
I contacted a supplier in Melbourne and he will make 12mm spacers to suit an inlet manifold gasket I sent him.
In the Group Purchases section you will find a Group buy under way. Currently at $70.00 per set of 2.
The only downside I see is we may have to replace our manifold mounting studs with longer ones (or bolts) to accomodate the extra thickness.
I plan on doing away with the MLS gaskets and use hi-temp silicone each side of the spacer.
Another thing I plan on is to cover the bottom of the manifld with phenolic material as this would stop the heat soak from the valley being radiated onto the bottom of the manifold.
I'm hoping to finalise the GP early next week, probably on the 16th, so if you want to be in on it please sign up.
