Piston squirters?
Trending Topics
There is no need to spend the extra money to make the 500 HP engine have the squirters. People drive around on engines that make more than that every day reliably with no problems.

Verdad Gallardo I thin its one of those "it depends" questions. If you have the money to do it, it cant hurt. Your engine will run cooler and take some of the slack off the cooling system. Expecially if its road raced.
Also depends on the car. I jsut got into a built C5 from a GTO and these cars normally run 40-50 degrees hottor because of the way they injest air. I would love to have piston squirters on the vette because the stock cooling system cant keep up with the 95 degree weather here. I can barely get on it without it starting to get really hot. Everything in the cooling system is nice and clean.

Ditto that. Strip engine of no real benefit. FI circuit engine maybe. GM didnt put squirters (piston crown cooling) in the LSA and LS9 just so they could say they had them. They were largely needed to enable long term durability (100,000 mile warranty) objectives for pistons/rings/little end that may see some circuit or extended high speed highway running. And maybe even short term crown area temperature control within the design objectives. It also means they can run tighter piston to bore and keep the noise level down. Plus these days with low friction thinner rings less heat runs out through the rings to the cylinder wall.
