Ok I asked a question if anyone knew where I could obtain these a few weeks ago. I think its only fair to elaborate on exactly what it is I was looking for now that I have completed what I was looking to do.
Oil squirters cool piston crowns so the engine can run higher compression without detonation. Here we see a block with the Squirters drilled into the jackets enabling the oil to be used in another way other than designed normally.
ok now why ?
Conventional cooling system design results in cylinders that are too hot at the top and too cool at the bottom.
Uneven cooling distorts the cylinder bores and increases internal friction. Downstream cylinders run hotter because the coolant reaching them is already hot.
A more careful design of the cooling jackets produces more uniform cooling, with a lower average temperature, at a minimal additional cost.
So, Piston oil squirters help cool the underside of pistons, so the engine can run a higher compression ratio without knock.
I hope this makes things a little clearer to those that were asking just what exactly I was talking about.
