Can the stock motor support a supercharger

[Gumby]

well 6.2 has 2 more cylinders

 

[New recaros]

well it has 2 more cylinders

Your point?

Don't worry guys, there's not enough Starbucks talk in the Gen 2 forum to keep them busy.

3.5
Bore is 92mm or 3.622 inch stoke is 86.6mm 3.409 this = 582.66666cc so basically if the 3.5 had 2 more cylinders it would be a 4.6L
6.2
bore 102mm stroke 95mm =775cc
That is a difference of 192.4cc per cylinder.

These are Flow # How well head will breath. Displacement is another topic. Not that we can't have that conversation. The numbers I gave you is Just the Intake/ exhaust of one port not the entire head. Not the entire displacement. We can do the math if you would like.
3.5
@.550 total head flow would be 1572/1146
6.2
@.550 total head flow would be 2440/1528
Not quite your 40% The numbers are the numbers. I will leave the % to you to figure.LOL
These are raw numbers NO Intake No headers and both of them can play a part on torque and RPM. Air flow in general.

1572/3.5=499 per L/displacement
2440/6.2=393
Total head flow/displacement, does that not show the 3.5 head is about 22% more efficient? What am I missing?

 

[Nex]

Man, you all must be getting the expensive hοοκεrs. Mine doesn't give me that kind of head flow.

 

[New recaros]

Low flowing head is better than no head.

 

[Gumby]

I am not saying you are missing anything. I didn't engineer the engine. Without taking in cam, turbo, naturally aspirated, intake, exhaust, throttle bodies injectors, and all the stuff that makes it go. The head flows what the head flows. Dose it flow enough for the displacement. IDK. I am not that smart.I am smart enough to know how to compare apples to apples. I am not smart enough to build a cam to use all the air flow.
I have never seen a head flow comparison compared to displacement. One head to another. yes.... The camshafts will deal displacement. but what do I know. LOL
With the power. Both the 3.5 and 6.2 I was a little shocked to see the flow numbers. They feel like (when driving) they move more air. I guess when I think about it 573 (3.5) 763 (6.2) CFM per head is a lot of air. Any way.... They are Both impressive. I Don't think either one of them is choked up.

@FordTechOne Never mind think I found it.
3.5 Eco-boost
@.450 is 257/198
@.550 262/191

Not as good as I thought it would be . With your claims, LOL But pretty impressive for a stock head.
I am having trouble finding 6.2 I will keep digging I know the SVT heads are different than reg 6.2. correct?
Ok I found it.
6.2
@.450 is 278/177
@.550 is 305/191
There's your numbers. Not too shabby for not breathing well. Again not what I thought they would be. I thought they would both be low 300s/low200s

What does 3.5 have to do with OP’s question of adding F/I to a 6.2? It’s irrelevant. Where are you’re pulling these flow numbers from? If it’s per intake/exhaust port, that would explain a lot considering the 6.2 (2V) has one intake/exhaust port per cylinder and the 3.5 has 2 intake/exhaust. So the 3.5 numbers would be double what was posted.

Also, there are no “SVT heads”; they’re the same ones used on every other F-150 with a 6.2, right down to the XL.

This is where FT one and I go our separate ways. I/he can't really say if it will support a supercharger. It will bolt on. yes. You haven't given any info what your intention are for HP. What are you using the truck for. daly driver for you/grandmother? Once a month? Going to street race on the weekends? looking to get in the 10s? looking to tow a 10,000 lb camper? Wanting to run the Baja?
As a general daly driver 5-10 lbs of boost on your way to get milk and eggs. You will be fine. The supercharger should have its own cooler.

The S/C heat exchanger does not cool the S/C or the engine. It removes heat from the charge air that is developed as the as air is compressed. So net zero at best.

And has noting to do with his Question. More to the statement 6.2 are choked up. Don't flow. I was willing to take what ever answer I found. They don't seem to be too chocked up to me. When you look at the flow numbers. You saying they were. Well it got my Curiosity going. and it is ok if you still think they are. I typically agree on more than I disagree. With you...... Not out to prove you or anyone else wrong or right. Just wanted to know the true numbers.

Also, there are no “SVT heads”; they’re the same ones used on every other F-150 with a 6.2, right down to the XL.

I found that out but. Thank you but I Didn't know. That is why I ask.

Agree net zero at best.
