- WHICH ONE MAKES MORE POWER, 4.6L VS 5.4L? HOW MUCH POWER IS A VORTECH SUPERCHARGER WORTH? CAN I RUN BOOST ON MY 4.6L 2V MOTOR? CAN I SUPERCHARGED THE 5.4L 4V NAVIGATOR MOTOR? IS A 4-VALVE MOTOR BETTER THAN A 2-VALVE MOTOR? SHOULD I MODIFY THE MOTOR BEFORE ADDING BOOST? HOW MUCH ARE CAMS WORTH ON A SUPERCHARGED MOD MOTOR? CHECK OUT THIS VIDEO WHERE I RAN A FIRST MODIFIED A 4.6L 2V NON-PI MOTOR WITH PORTED PI HEADS, COMP CAMS AND PI INTAKE, THEN ADDED AN INTERCOOLED VORTECH SUPERCHARGER. ALSO INCLUDED AS A TEST WHERE I ADDED A VORTECH SUPERCHARGER TO A MODIFIED 5.4L 4V MOTOR, THEN TESTED WHAT HAPPENS WHEN YOU ADD ICE WATER TO THE INTERCOOLER.
Great timing . I was in the mood to hear about 4.6 and 5.4 because parts availability and here you are one day ago nice
Thanks for all the help and all your work. I appreciate all your advice and support in the live feeds.
I love mod motors. As long as the timing chain/guides are in good shape and some moron hasn't been changing the plugs, they just run forever. Yeah they may not be the most powerful thing on the road. But they are sweet boosted and sound awesome 👍
LT would love this video. He’s putting together a similar 5.4 now..
I’ve always wanted to build one of the early cobra 4.6 engines. I haven’t showed the mod motor much love.
Turbos Rule! I guarantee that your turbo belt will never slip.
Hey Richard, something I’d like to see if you could do it is 4v 4.6 NA engine builds, testing different camshafts and intakes and possibly different fuel types like E85
PLEASE SEE THE MANY 4.6L 4V VIDS
The whole Triton family emphasis was on torque production, the 5.4 was rated at 330 ft/lbs at less than 2000 rpm, in 2002.
Over rated af to. Those things were gutless wonders.
@@HioSSilver1999 No, they made great torque at idle. And no horsepower. Just like Ford claimed. GM trucks made more horsepower, got better fuel mileage, and are much easier to work on, but the 4L60 sucks compared to the 4R70, and the fuel pumps lasted 3 times longer then GM trucks of the era.
They’re junk. Drive a 2004 Navigator 5.4 then drive a 2004 Tahoe 5.3… not even comparable. Mod motors are 💩
@@boost1728 there are almost no surviving examples where I am, but all I do for a living is fix vehicles, so you couldn't tell something I don't already know....
@@jamesgeorge4874 obviously there are a couple things you don’t know- like the fact that first gen mod motors are gutless. Can barely tow a jet ski behind a 4.6 F150. Waste of time and money
My take away is that everything needs boost!
You sir are %100 Correct! Boost Everything! Thats my motto.
Please play around with the 3v 5.4.
I know this video is talking about boosting the 4.6 and 5.4.But when it comes to reliability i pick that 4.6 all day everyday!
They're practically the same lol
What? The 4.6 3v is just as shitty as the 5.4. The 2v motors where also exactly the same for reliability. Same with the 4 valve motors…..
+1
There's gotta be power power potential in that 5.4 N/A
There is.. Kaase builds 5.4s n they make huge n/a power with then, last i checked..
Boost The World! Everything needs Boost :-D
Richard, was this 4.6 a stock bottom end? Internet myth claims those motors don't like going beyond 500whp before eating pistons and rods. I personally think it's ring gap and tuning that are at the core of that problem but always love to see these examples that push the envelope a bit like your big bang experiments.
these are numbers at the flywheel. add drivetrain loss etc. a 500 whp 4.6 is likely making 20% more than that at the flywheel. I don't see a few pulls on the dyno causing it to spit its guts out.
@@wyattyeary8050 I'm fully aware. I'm also aware of a few blown 4.6s at 430-450whp and a few choice examples claiming 550whp. The real "limit" is illusive but Richards numbers are knocking on the upper end of what people consider the "practical limit".
Personally I think it's about 650-700 crank lb-ft of torque that's the limit, which with factory heads might end up being 500-ish whp. Improve the breathing and you can reach a bit higher in RPM and get better peak numbers.
Rods are the real weak point. Might make some power (500+) for a little bit, like a few dyno pulls, some pulls on the streets etc. But it's on borrowed time. The there is no getting around it. No amount of tuning will make a rod any stronger. In the real world they won't last long. They will bend/break and it's been proven many times.
I drive a 4.6 2v with a vortech, I can tell you 450 isn’t blowing it up. Been bashing on it for almost a year this way.
@@banneddamn rods don't reach their mechanical limit at a HP level though, but torque. The question is, when people bend rods at greater than 500whp, what torque were they producing? I'd also be curious how many bent rods were on manuals vs autos, as it could also be torque vs applied resistance (load). Autos are "softer" on engines, generally.
850 plus hp from 330 inches wow!
Also if you can swap out 5.42v heads for 4v
I thought that the 5.4 NA power curve looks like teeth off a wood saw. Any idea as to why it was doing that Richard?
I would say belt slip
@@myronwebster unlikely as it's not running the blower at that point in time.
The 4 valve engines make monster power.. That is why the crotch rocket engines use them
Can you do a 3v
good video. but what's that rifle in the background?
PELLET GUN
Did someone say Mod Motor?!
Hey Richard I have a 5.4 2v and was wondering if you did any testing on those as I only see 4.6 2v of 5.4 4v
The 5.4l responds the same as 4.6l
2000 FI50 5.4 STOCK COMPUTER SMALL TURBO FMU FUEL ENRICHMENT NO CHK ENGINE LIGHTS MUST PASS SMOG ?
10th gen body style is the same as the Lightnings were, so just get the Lightning intake manifold/intercooler setup and supercharge it. My 98 F150 4x4 is done this way and I run a Whipple 2.9SC on it now. I ran the ported Eaton SC for 12 years before I went to the Whipple.
Good evening building non roller 351w want to make it roller. What length push rods with link bar roller lifters.
NEEDS TO BE MEASURED
Cool testing 😎
npi was 1991-2/2000 in panthers
NA 5.4 4v with navi heads ported didn't make more power with a sluivan intake??? Wtf
How much hp can the gen1 mod motor handle ??
Test an Atkinson cycle engine
You already know about them, nobody here is wondering how boring an engine that gives up low speed power, for efficiency, would do on the dyno, plus, the are inherently small, usually coupled to a motor/generator, and not a platform that is plausible for power gains, because their intent, from conception, is the opposite. The Miller cycle engine is as close as you are going to get.
Watch out for the scammers people. There are NO prizes and if someone asks you to pay for shipping it is NOT Mr Holdner, trust me.
Thnx JPL-I don't have any prizes nor would I ask for shipping costs!
So the built 2v 4.6 was only down 40hp from the built 4v 5.4? Odd.
A 40hp difference is about 4 tenths in the 1/4 mile. Example 11.80’s vs 11.40’s..
I make sure to make plenty of mistakes on my engine builds so I can learn to make less mistakes...
Nice!
Can you put 4v heads on a none pi 2v block?
i THINK SO
3V 5.4 please
Worst engine ever made? No thanks
Hence why it would be interesting
Personally I blame squirrels
I hate squirrels.. They’re always digging up my yard.
@@sstevocamaro damn bastards plant nuts in my gf, and I can't... something about those furry things women Love.
@@sstevocamaro furry jerks :(
I love squirrels...grilled.
@@timkox2976 never had squirrel, would like to eat some sometime
Would these mods apply to the triton 4.6 2v as well?
yes
@@richardholdener1727 In Australia we have a Ford V8 that uses a Windsor 331ci bottom end with Cobra R 4v Heads that in its day made 349hp with 500nm of torque or 260kw in new speak, can any mods be done to the Cobra R heads & cams? It's a bulletproof engine.
@@mickblack3291 Bigger cams yes, ask around over there..
Is this with a stock bottom end on that 4.6l
yes
@@richardholdener1727 good stuff, would like to see the 800hp 2v you did with the bullitt intake and jt trim
I can’t believe that the 5.4 makes basically the same power as the 4.6 in naturally aspirated trim!!! That’s not good.
it made nearly 40 more hp
@@richardholdener1727 but it has 50 more cubic inches and 4 cams!!! It should have made at least 60 more
@@scottsigmon926 are you under the impression that more cams add hp?
@@robertkington2084 they definitely make the engine more efficient and in many cases, yes, it should make more power. The cubic inches alone should have made more than 40 hp
@@scottsigmon926 number of camshafts dont change VE. If it had 32 individual camshafts the engine would not care. It all boils down to what heads were used during the test. If they used non pi 2v 4.6 heads then compared them to a 5.4 with the Ford gt heads then you would see well over 100 hp gain.
First comment yeah lol
This dude gets it.
Fordies...
Are you sure?

Everything likes boost the same. It's just more noticeable on those things because they're gigantic turds.
