I don't have many secrets, The exhaust ports were coated to keep the heat from transferring to the water, that is the only coatings we used.
We were lucky, on the first pass the driver said he would take it easy and went 204 that was good for the record so we put it in impound. The next morning we towed it to the line for the back up run and it was missing we checked the plug wires etc. and could not find the problem. We put 2 more lbs boost and told the driver to go for it. Running on 7 cylinders it went 212. And got him in the Two Club our goal. Found out later one of the valve seats came loose and was holding the valve open.
He has since sold his car and stopped racing.
My 37 has no coatings but I plan to use some on my next build.
