2013 GT's have different pistons and no squirters
- Thread starter RTD
- Start date
That's a tenuous connection between the statement that the 13's don't have the piston jets. While it's a 5.0 TiVCT block, that doesn't mean that it's exactly the same as the blocks that go in to the cars themselves.
Especially considering that Ford official dealer communication states they are still there.

That's Ford's own esource for the 2013 changes and features. Page 11 under 5.0 TiVCT key features.
More than likely, that block for sale is a roadrunner block, which has never had piston cooling jets and likely no provisions for them.

i agree lol
Probably has to do with the type of internals and how they handle heat
could be true. i wonder what the cost offset actually is between the 2. not what we pay. but what it actually cost. since they use different internals between the 2 but one adds the squirters which is an added cost.
So would not having oil squirters be bad for a supercharged engine?
well i would say for a high rev engine it may be better without them. it may also be one of the issues for higher oil consumption.
FRPP said they got rid of the oil squirters on the Boss because the were losing HP at over 7000 rpm and didn't need them because they were going to forged pistons anyway. They also said that the GT's hyperuetectics would not survive without the squirters at 7500.

The Boss has forged pistons, the GT does not. That is the reason.
IMO, yes absolutely a bad thing for those planning to go FI on a 2013 GT.
Did you even read the description of the block in the link I posted?
Let me bold the important parts.
Yes I did, but again, you've got highly conflicting evidence. It may be a production block, but that doesn't mean it's the same block that actually makes it in to the cars.
Why would Ford lie to their own dealers about what the engine has in it? That Esource is meant to be a sellers guide. What you're saying is that Ford is trying to have it's dealers actively or unknowingly lie to it's customers.
Look, changes do happen and if Ford felt it was cost effective and advantageous to do so, they probably would.
Thos poiston cooling jets are there for more reasons than to just cool down the pistons. They aid in warm-up which reduces carbon emissions as well as helping the oil to shed any condensation earlier in the drive cycle.
Even if Ford did go to a forged piston in the 2013's (or late 2012's as some that have started this rumor have stated), I'm guessing they would have still used the jets.
The reason they're not in the Boss is because of windage issues and high RPM use. That's been documented, where as this, has not and is simply a rumor being thrown around by people wanting to poke at that 8 hp increase.
Until you see a release from Ford themselves about the changes, I wouldn't take a block for sale meant for enthusiasts as a smoking gun on what is or is not inside the actual production engine.

wasn't the 11-12's the first year of the oil squirters? That could be one of the possibilities on why they have a high oil consumption.. never though of that
I would think if the oil jets were the problem, everyone would have high oil comsumption. There are also a few other cars and all HD diesels that have been running oil jets for decades without a problem.

Yes the 2011-2012 were the 1st year of the squirters.
Why couldn't the oil jets be ONE of the reason of oil consumption? We already know one of the issue is the pcv on the gt doesn't work that well causing oil consumption. So I believe its a multi part issue that causes the oil consumption on some 5.0.
link to thread on s197?
Not that this pertains exactly to this scenario, but a lot builders will delete the oil squirter when building forged motors as doing this will increase oil pressure and "it's one less thing that can go wrong in the motor"
