Full Race's "Gen 2.5" Raptor build

[full-race geoff]

Hey @full-race geoff Did you ever determine if the Raptor R motor mounts will work on the 3.5 block?

Parts 1 and 2 in this diagram:

I believe this is the left-hand side part #: https://www.fordpartsgiant.com/part...bmodel=&extra1=&extra2=&filter=(r=1877;e=730)

And this one is the right-hand mount: https://www.fordpartsgiant.com/part...bmodel=&extra1=&extra2=&filter=(r=1877;e=730)

They look very similar, if not identical to mine, but would like to see one and measure first. Just wondering if you had the opportunity to do so yet.

Sorry I did not do this yet (been focused on bronco raptor/ranger raptor 3.0 and 2.7 Ecoboost). Right now parts are piling up, and I need a solid 2 day wrench-fest to get things in a good place, hopefully early March

The ford system shows the part as fitting 2022-2025 f150 soo I’d be surprised if it doesn’t fit up

the Hybrid variant. Might be worth looking through part numbers for differences.

That’s a great point. The hybrid variant might have some differences to the standard 3.5L worth exploring

Sadly my contacts that helped Full-Race with previous gen 3.5 projects left Ford during a mass re-structuring. As you’re probably aware they and many others left as part of a corporate mindset move away from ICE’s toward electrification. A huge amount of 3.5 eb knowledge and experience gone

That's all just a fancy way of saying, you only need it if you're losing head gaskets. The 3.5 does have a pretty large bore and bore spacing so it's not a bad idea if you're shooting for big power (800+).

Agreed that 800+hp warrants consideration of cylinder support. However ethanol and soft ignition can go a long way at safe power production. My only pushback to the CSS is the stock sleeve can still crack, it just won’t shatter (detonation typically). it may be a safer bet than a ductile iron sleeve or it might also create headaches with sleeves moving.

Long way of saying 700hp is the reliable / safe ceiling I want to work toward and the stock open sleeve block should be fine with that.

I have MPT doing the tuning on my set up and I intend to have him attempt to find the tables in the tune file to shut this function off completely.

Please let me know if he can do it? I still think a dummy solenoid may be necessary

FYI - biggest discount I’ve ever seen on boostline rods direct from the mfg

and if anyone is feeling like a roll of the dice, amazon now lists 17-20 metal valve covers:

I shouldn't be so "intrigued".

WAIT! reread description... its plastic with aluminum inserts.

you’re right. I saw it listed here and the title is unbelievably deceptive… “2x Aluminum Engine Valve Cover For Ford F-150 F150 2017-2020”

Geoff,

I tried to order those metal Gen 3 turbo tube mounts and only the driver side was coming in correctly. The passenger side is WAY different that the Gen 2. Did you find this to be true on yours as well? maybe there is a part number that I am missing?

 

[full-race geoff]

Correct - driver side is the one that needs replacing

big thanks to @dillard09 for sharing the photos of his failed ‘built’ engine with me. An accomplished machinist spotted the issue

“Take a look at picture #2 you can see where the aaftermarket head gasket appears to have literally jacked up the head. This is something builders have to be extremely careful with. Cometic started putting their layer interlock inboard vs the old copper rivets outside the block. Unfortunately they did not consider how popular close decking or sleeving has become. So as customers bring this to our attention we have been updating our support rings to eliminate this issue.”

I believe these aftermarket cometic headgasket rings did not allow the head to fully sit on the CSS block and created a leaking head gasket condition. Unfortunate that stock sleeves and/or an oem gasket may have avoided this



Explains why goose couldn’t get it running properly and eventually dillard09 cooked the gasket and torched the block.
