@ 430 hp and only 475 lb-ft....i guess the V8 in Raptor crowd will pipe down

[MTF]

Ummm yeah I did, that’s why I said that. There’s basically nothing different w/ the engine itself, but the intake, the turbos, & the entire exhaust is what contributes to the bigger power (along w/ tuning obviously....not to mention the GT is tuned to run from the factory on 93...raptor would probably be rated @ 480hp if it was tuned for 91+ octane exclusively)

Maybe you should do some research. I’ve also been told this by various performance shops when learning about tunes & one of the things they bring up is how the engine is easily capable of handling more power b/c of that fact. The tranny is the same GM is using in the camaro ZL1 etc. so it should be good to handle additional power as well.

I think cooling is the biggest factor for the Gen 2 raptors- I plan on adding a larger intercooler & a tranny cooler even if I remain stock tune-wise this will result in more consistent HP & better performance. If/when I do add a tune it’ll be more suited to handle the extra power.

Back to original subject- the 7.3 is probably gonna be a good n/a V8 truck workhorse motor, & as much as I like V8s I still prefer this- like someone else mentioned this was a full ground up redesign for the Raptor & learned from mistakes on the first gen (like beefing up the frame & shock mounts for starters) while the first gen was kinda a “work in progress” hence WHY it wound up initially w/ an engine that belonged in a regular F150 & then later w/ a bigger displacement HD gasser engine- not a super car engine.

My understanding is the Raptor shares the heads/forged crank/pistons & connecting rods w/ the GT. The compression ratio is similar too I believe- but not sure. Block is obviously the same. Why is it difficult to believe that if you installed bigger turbos, a freer flowing intake/exhaust, higher compression ratio & engine mapping for 91+ octane that this engine would EASILY make the power it does in the GT?

https://en.wikipedia.org/wiki/Ford_GT

The car is powered by a 3,496 cc (3.5 L; 213.3 cu in) Twin-turbocharged Ford EcoBoost V6 engine generating a power output of 647 hp (482 kW; 656 PS) and 550 lb⋅ft (746 N⋅m) of torque.[15] The engine shares many components with the F-150's 3.5 L V6 engine including the cylinder heads, block and dual fuel system. Notable differences include larger turbochargers, an aluminum intake manifold, a custom dry sumped lubrication system, unique camshafts and higher strength rotating and timing drive components. At the time of introduction, the Ford GT had one of the highest specific power outputs of any production car.

If you guys think your gonna get these numbers on HO 3.5L your nuts.
The GT employs a four-stage external dry sump oil pump and has an oil capacity of 15.3 US quarts (14.5 L).
That's just one thing you are going to have to do to keep the motor from blowing up.
Then after you spend another $30K with aftermarket upgrades (which doesn't exist) you may have something.

There's no reason you couldn't come close to those number with the proper supporting mods. Dry sump oiling isn't keeping anything together other than during high G cornering at the track.

20 hp and 35 lb-ft is just intake and tune away for the 7.3. Flatter torque curve. Even at those numbers in my opinion would be far better engine for a Raptor.

I hope your kidding...Did you take the weight of the new engine into account? Do you realize it would have to put out even more HP and TQ to make up for that...what about what it would do the the suspension/handing characteristics? Me thinks you are simply trying to argue...LOL With the exception of sound the 3.5HO TT V6 is an amazing motor and simply perfect for the Raptor and the better than any other production truck in existence for it's intended purpose

I rather have v8 then 3.5l anyday
Doesnt mean 3.5 are bad i just prefer 6.2 v8 and the sound and reliability of the 6.2l nothing like sound of v8 threw your exhaust

Interesting the timing components are different. I wonder if they are strengthened or designed different for the different size cams.

I'm sure there is more in that engine then what was leaked out.

Well, how many GenIIs have failed because oil wasn't getting to the pickup tube, there's been a few that I read.
I also have read that the oil pan had been redesigned to help with that, don't know if it's standard now.
Granted 4 Stage 15 quarts is over kill but at those high HP numbers and running hard the oil is going to cook.

There is a big difference in V8 sounds... (seems to be the #1 reason people prefer a V8).

Dodge and Chevy trucks (even older Fords) pull up near me with loud exhaust systems and it sounds like crap... like a boat.

It needs to be a crisp, raspy snappiness to the note... not a bloaty, wafting, ogre sound.

LOL who’s arguing? 100lbs is not much heavier. It’s a truck not a full on race car.

Well, you can't compare a forced air with a 10 speed against a 6 speed naturally asperated either!

Put that 10 speed in a NA Gen 1 and the Gen II wouldn't have a chance.

Sure you can. You have two more pistons and nearly twice the displacement. It would take you a lot more than extra ratios to beat a gen 2.
