piston oiler/cooling

[grumpyvette]

yes I know, I hear it all the time, Why bother, "if those piston oil spray gizmos really helped the factory would have installed them"

well NEWS FLASH! the new corvette engines come with them installed from the factory!

these little oil spray jets tend to reduce the chances of detonation destroying rings and pistons by reducing the piston operating temps, by constantly bathing the lower piston in oil, which tends to be more than 100F or more lower in temp than the piston runs without the oil spray cooling it. this requires re-routing some oil to jets you install in the block to allow some oil going to the main bearings to flow to the squirters to enhance piston cooling, normally oil thrown from the rod bearings keeps the rings lubed but the squirters do a more consistent job on the pistons

heres a few pictures of modifying a big blocks lower end to add oil spray jet coolers to cool the pistons
