Classic case of not seeing the forest for the trees. Also, just because one can assemble an engine, doesn't mean one understands how they work or how to improve them.needforspeed66gt wrote: ↑Sat May 16, 2020 1:17 pmAll the Honda and import racers I've seen eliminate the oil squirters....and then wonder why they trash pistons so quickly and they're black on the underside, I don't even bring it up anymore, they obviously know better.Fusion Works wrote: ↑Sat May 16, 2020 12:04 am Many high performance Japanese engines also use multiple slots on both side of the rod cheek . I figured it was to "leak" the oil in a specific direction instead of just letting it sling off where ever it goes naturally.
These are on the bottom of Honda production engines.

A bunch of engine builders block them off to increase oil pressure. Doesn't seem like a good idea. Honda spent a bunch of production money to put them in the engine. Not sure how a race motor would survive without them.
Unfortunately it's rubbing off onto the LS crowd and even though I go to great lengths to retrofit in pressure activated (OE BMW) in many endurance builds and have seen without a doubt that there are great benefits to doing so in piston life, power, etc....many come in wanting their OE squirter equipped blocks (LSA, LS9, LT4, etc) to be blocked off because that's what they see done on the internet.
Piston oil squirters are a very good thing as long as you do it properly and don't starve the system as a whole.
My guess, if they took advantage of what the squirters allowed them to do, they would gain way more than any windage gains they would see, let alone the reliability.
