Is Supercharging a 2019 4.6L possible?

Hi Guys,

Do anyone knows if there is a kit or a way to supercharge a 2019 4.6L DC?

Thanks.

 

Not currently but you could be the first

 

If you’re dead set on a 4.6 use a unichip.

or get with Mat Wilson at OVtune

it’s possible. You just really gotta want it.

 

One of those "I should have bought a 5.7" moments...

 

My son went through a classic Volkswagen period, and bought an old VW van. Due to his learning curve, he was constantly rebuilding that old pancake four cylinder due to his latest "experiment". He was constantly showing me articles in these VW cult enthusiast magazines on modifications to make those flat four cylinder engines yield an amazing 150 horsepower.

The mags, of course, were designed to sell aftermarket parts. Even with the enhancement, a flat four can not compete with a modern V8 regards power. As an exercise, souping up a flat four was a satisfying, but expensive, challenge. And, that is where supercharging a 4.6L would fall. The result would always be short of what would be available with the 5.7L.

Two things: (1) All performance is relative, and (2) There is no replacement for displacement. Spend the first $10K dollars to upgrade to a 5.7L if it's high performance you need.

 

I didn't even know 4.6 was an option....

 

Wouldn’t supercharging a smaller displacement engine like the 4.6 makes more sense because the engine has better chances of revving at a higher rate than a bigger engine?

 

The two engines are both from Toyota's UR family, and are virtually identical in all respects except for displacement. Published redline for all UR engines is 7300 rpm. Source link below (see right sidebar):

For the people dogging him, my guess is that a supercharged 4.6 would be a much more fun vehicle to drive than a stock 5.7.

that said, you’re never going to get your money back on resell of an SC 4.6 like you would on an SC 5.7.

the 4.6 trucks have an additional problem which is the axle gearing. If the 4.6 had the 4.30 axle ratio like the 5.7, it would drive MUCH better. I owned a 4.6 truck with the 4.10(they dont even offer that anymore) and the 4.30 gears are much more noticeable in street driving. The 4.6 is no slouch as an engine, it has plenty of power. I traded it in before 4.88 gears were available, i wish i had kept it!

 

Just received my Nitro 4.88's! Have yet to be installed, but an looking forward to it.

 

Thanks for this man! This is exactly what i was looking for. Expensive though...

 

I have the Nitros 4.88 gears and the truck behaves so much better.

 

This thread really interests me!
I actually went so far as to contact XAT Racing in FL about the exact pricing for their 4.6 (1URFE) supercharger kit (can get them down to $7000). Bullet is claiming 350+HP at the wheels which would be amazing for me, and here is why:
I live at a little over 10000' above sea level. Naturally aspirated engines lose about 3% of power for every 1K', so up here my truck is making 217HP at the crank, and the 5.7 makes about 272HP at the crank. A supercharged engine still loses power, but this is easily compensated by changing pully size (especially since my truck NEVER drives below 5K').
This is one reason why diesels' are so popular up here.
I'm not looking to build a race truck. I just want to be able to maintain 70mph on the freeway without kicking down to 4th gear! Or I could buy a dang Ecoboost.
Thoughts?

 

id consider lower gears since you live in mountain roads

 

Question is, could you sell your truck and use the $7k you'd spend on an SC to buy a decent diesel in your area? Are you taking into account the mandatory 91+ octane you'd have to use at the pump post-procedure?

Not that diesel is the cheaper alternative at the moment......

 

Oh, I've thought about it. I actually have a 2008 6.4 King Ranch Powerstroke that is deleted and tuned. But it's the most unreliable vehicle I have ever owned. The Tundra is the BEST vehicle I have ever owned (although I know adding forced induction could/would change that).
I'm sure at the end of the day it would be better to simply get a truck that suits my needs more accurately (Duramax Chevy Colorado?), but adding a supercharger to a 4.6 would be such a fun experiment!

 

At the end of the day, it's your money and how you choose to spend it is your business. To hell with whatever ppl think.

 

Is tuning support gonna be an issue for 4.6?

 

What you really need to do is adjust the air/fuel mixture to draw in slightly more air. Truly that simple.

 

WhiteSmoke, is this possible? I assume I would need a custom tune like OVTune in order to achieve anything other than a stock air/fuel ratio? It's probably not as easy as adjusting the throttlebody on the old Toyota pickups......
My truck is currently stock. Going to do SAMB and 4:88 gears this summer. Then decide on the blower after said mods.

 

The air is less dense. You cannot draw more in. There is only so much volume in a cylinder. You can push more in with a blower, but not draw it

 

Yeah. Why didn’t anyone think to just adjust the air fuel ratio to get the power back at altitude?

Probably since engines draw in a certain amount of air (what the cylinder will hold) and the air is less dense at altitude there is no way to just add more air unless you force it in there... With a supercharger or turbo. Hence his question.

 

You can't draw in more air than what atmospheric pressure is already trying to shove in, what a complete bullshit statement. Running lean which is completely different can possibly make more power but is very dangerous.

 

First off make sure you have a Performance air filter, possibly a better intake altogether if you don’t already. And then you need to gain access to the ECU and turn up the air mix slightly. You might want to ask a dealership or someone who’s really good with the ECUs. This is why old cars are awesome you could just tweak the carburetor with a screwdriver.

 

Unless you have a magic spell to increase atmospheric pressure, there is no shoving more air into the engine other than a turbocharger or supercharger. At sea level atmospheric pressure is 14.7 PSIA and that is actually the pressure of the air going into your intake. At high elevation it may be 12psia all depending on how high you are. That means naturally less air pressure going into the engine, and less oxygen. As far as Intakes, they really don’t get better than the stock intake box with a high flow AFE filter.

 

No you definitely don’t need a magic spell to get more air to the engine. Although I don’t think an new intake will help THAT much, it’s more about increasing the flow of cold fresh air around it, which people have been modifying their cars to do for decades and decades so I’m done trying to explain that. Ultimately turbocharge/supercharge would be the best solution but I’m just thinking of possible alternatives that will cost a fraction of the price. Here’s a link about airflow and it’s connection to power for anyone who’s interested. Good stuff. https://official.bankspower.com/tech_article/airflow-the-secret-to-making-power/

 

That info is great, and The OE intake is more than capable of delivering enough air for a 4.6

 

The 1urfe 4.6 sc by bullet would be nice combine with the ovtune.
