Anyone tried using under piston oil jets/squirters to cool the pistons on an E series engine?
Any pro's and con's to using them?
I've heard they are supposed to supress knock cooling the piston after the exhaust stroke, ready for the fresh intake charge.
A lot of the vauxhall boys use them, and they come on a lot of new cars as standard, so they must do something good.
Heres the way the vauxhall lads do it... http://www.vauxhall-sport-forum.com/phpBB2/installing-under-piston-oil-squirters-t265.html
Although it can be done where you have a feed to all 4 jets plumbed in from a main feed.
Any pics are welcome
