How many of you not running oil squirters in your 2.4l
Drag racers remove their oil coolers and will no notice no ill effects. But savy road cars will have larger than stock size oil coolers to control oil temperature.
Oil squirters are there for same reason oil coolers are. controls piston temperature. Forged pistons have a larger expansion rate than cast pistons. My thoughts are they are needed more for forged pistons, not less.
HP= heat. the more you make the more important controlling heat becomes. Sorry if good shops dont recommend oil squirters. Not much intelligence as I see it.
This will be my only contribution to this debate,

Those are the best turbine housing covers I have seen/used and work extremely well. Two layers of inconel with a high temp insulator between.

ME? NO!
Am I in the right thread? If so they why are all these guys with different makes and models commenting on their opinions on oil squirters? Yes I know Will, every thread ends up like this.
Who cares what motor you ran your oil squirters in. If you dont have a 4G64 2.4L, or never had one, then make your own thread on how glorious they are. Even better,.... Go do some testing! and post results. The OP doesnt care what your geo metro with zex 50 shot ran down the 1/8, 2 yrs ago.

Guys - We are all trying to make these motors as best as possible. Let's try to help each other out however possible.
Mikey - Thanks for your reasons for not using squirters. As I acknowledged your reasons are why drag racers don't use them. For those of us that road race (or did) the more common practice is to use the oil squirters. (Thus my bias.)
Aaron - I totally agree that an engine builder would have to ensure that the the piston does not hit the squirter. I also believe that most would be fine running without the squirters. I just feel for a road race car or one that is pushed really hard for long runs, the squirters would be added benefit.
Rockman - I was just saying that I never said squirters are required and then you posted saying I did...It's all good.

If you don't like the reference then don't take it into consideration. People are only trying to

from the factory most standard motors don't have oil squirters. they only put oil squirters to their high performance motors. this is true to all manufacturers including the exotic car manufacturers. these car companies have spent a lot of money on r&d so what does that say about oil squirters?

....Ferrari - squirters
Porsche - squirters
Corvette ZR1 - squirters
BMW M series - squirters
Audi - squirters
Formula 1 - squirters

1) They have cast pistons or...
2) Ti Rods or...
3) Composite Rods or...
4) All of the above
I'm out of this thread. All of this has been stated. I feel 100% confident in saying that Forged Internals don't need oil squirters, also most of the exotics you guys are talking about have dry sumps which is okay to run oil squirters because it wont take away the oil from the bearing/crank and oil pressure remains constant. You guys can't compare a 4G63 to a Bugatti Veyron

Mikey, Subaru STI engines run forged pistons and oil squirters stock. (ej20)
A local race team has noticed when they do not coat the piston crowns, there is scorching on the bottom of the pistons because they get so hot.
With the coatings (ceramic etc), there is no scorching on the bottom of the piston.
So that is something else to consider, the actual temperature that the piston gets up to.
So things like piston to bore clearance will be a factor in regards to whether people are running oil squirters or not.
With the oil pressure debate, i reach max oil pressure at about 2800rpm (~80psi with hot oil). I dont see how oil pressure will increase without using oil squirters, unless your oil pressure relief port is too small. Granted that the flow through your oil galleries will be less, but the pressure should be the same.
Oh and does oil squirters help wrist pin oiling?
Cheers, Mike

As 94awdcoupe said, forged motors are more likely to need squirters. They expand a lot more. With squirters you should be able to run tighter clearances which will prolong engine life.
Oil squirters lower piston temps. Lower piston temps mean lower detonation potential, especially under prolonged, hard running. Lower thermal stress to the pistons and oil film also means lower rates of wear.
Squirters are one race engine development that makes good sense for street engines. They are always an upgrade, and never a downgrade. Having them is better than omitting them 100% of the time.
Whether adding them or not is worth it is your judgment call, but facts are facts. Do with them what you wish.
That's all.
