I'm a pretty serious mods type guy and my new to me unlimited is driving me nuts just sitting there. I've contacted most of the blower suppliers and no one has heard of a modern, non-junker, real life situations type, blown Pacifica. I have too many projects and too little knowledge to do this myself, so...tell me of a completed Pac so I can copy or tell me of a shop talented enough to pull this off in an acceptable amount of time. Most jeep places are just assemblers with little peripheral skills but I'm hoping someone knows someone brilliant. I can build/modify the hood and finish items. I can't reprogram the ecm and bcm or go through all the accessory drive part trial and error.

I don't care about longevity or sintered rods vs forged, I'm not looking for more than greatly increased 50mph to 80mph speed(tourist/left lane driver passing speeds). Resale isn't a concern.

As I understand...stop dreaming....

I am not a novice who saw

then got the tattoo.
I've been at this since 1975.

Some of us here aren't particularly unknowledgeable, but particularly knowledgable enough to follow the path blazed by those who spent the research money, or not take the journey.

I'm smart enough to do the job, which makes me smart enough to hire a professional to do the job.

I've blazed enough paths. I'd like to follow one.

Fourth time in almost as many posts.
Passing speeds to counter 50mph goofs on 65mph two lane roads.
It is a regional thing.
And
I think we're dealing with some people who only read the topic headline.
I couldn't have been more clear...many times.
95mph and light towing was never mentioned. Fuel mileage is absolutely, laughably, no concern. No one said turbocharged. No one said family.

I didn't buy it as a mommy wagon.
I bought it as a basic base for my not basic mods and usage._
It's a carry all, that's all.




I'm out.
No usefulness for me to pursue it here.
Damnation!

A quiz:
Who knows the name of the Jethro Tull album which reflects more than one poster in this thread?

Well, some of us gave useful information, you just choose not to listen due to thinking you know better despite never owning nor working on one of these vans. Just because you don't like the answer doesn't mean it's not useful.

You want more 50-65 passing power, upgrade the air intake, port the intake manifolds, open up the exhaust, have it tuned.

Stop ***** foot driving it all the time so it reacts as it should when you kick it down. At 50mph, my 2019 hits 2nd gear, no lag, no one gear at a time, I step it down, it downshifts to 2nd, hits the fat of the powerband, and screams up to 75-80 mph without missing a beat.

I have owned many mini vans, my latest a 2017 Pacific with sufficient horsepower to do anything that I've ever required of it. The van cruises is nicely at 95 it gets remarkable mileage at 60 mph, I have towed a loaded 12 foot U-Haul trailer across the country without a problem. What benefit do you hope to derive a turbo charging the vehicle?

So to answer your question why not? You have a perfect family vehicle capable of getting 35 to 37 miles per gallon safely. It's has great traction, great handling and can easily do 100 miles an hour with great acceleration. so I restate the question what's the objective?

It has decent traction, decent handling, and decent acceleration. All of those can easily be improved by simple mods and upgrades to make it truly great.

Anyone who does mods almost always shares the same objective, to make the vehicle better suited/more specialized to their specific needs. While it may be "good enough" for you, I want it tighter, more responsive, and quicker.

I considered the nitrous shot.
But by the time I purge and set, the opportunity to pass some stupid 15mph under the limit, mobile chicane GUMP will probably be missed.
I have a BlackBear tuned 500hp 8.1 big Block avalanche and a tuned zr2 blazer. ALL my vehicles(even the tractor) are modded to some extent. The king ranch we traded in on the Pac was full Coyote equipped and tuned.

The blower is easy.
The tune and drive pulleys are not.
I might buy an ecm and give it to a tuner as a jail break experiment to verify breakability and values.

My hope is that jeep values and parameters translate due to mopar money saving interchangability.
50mph to 85mph is my only interest.

This is sitting in my garage. I have a blower guy.

All depends on the engine. Most engines can easily handle 6-8lbs without issue if tuned properly. 10-12lbs is not outside the realm either, again, assuming it's tuned properly.

Some older NA engines, such as the SOHC 6G72 Chrysler used to use could easily handle over 20lbs on stock internals, with a handful of guys even pushing close to 30. Having it tuned and running properly is the key.

You are NUTS! I believe you have money to waste to prove a point, well the problem is the engine needs heavily to be modified all so ECU to reprogramed that is not only problem you will have I don't think the trans can handle the extra torque to but not to worry someone will find or build you the Mouse trap you looking for and get the money you willing to pay. My suggestion remove the original Engine and trans pot it on the side for lather day and go for oder engine with six speed tans and engine with a factory turbo. Let us know if our suggestions works for you.

I used to work in the tuning and aftermarket performance industry. Specifically, I would build and balance turbochargers: I had a turbocharger shop.

Almost all engines and transmissions can handle 10-12 pounds of boost safely. Really really good "freak" engines that already had forged pistons and rods from the factory could usually go up to about 450-500 HP, so 20 lbs of boost+- depending on the compressor size, etc.

The upgrade path is this: you pay a shop to fit the supercharger, piping, intercooler, all of the physical parts. They figure out how to tune it, get you anywhere from 50-100 wheel horsepower for $8-10,000 or so. Sounds expensive, right?

Well, after the system is fitted and tuned, you bring in an upgraded engine and fit that. The blower pipes and tuning are figured out, so you unbolt everything, put the new engine in, retune, and you make 500 hp and see how the transmission and driveline hold up. $5-6,000 more, and you've got a van with 500 hp. Kind of cool.

Your cv shafts/driveshafts go pop, and you take them to a custom driveshaft shop. They exist in the import world, it's not reinventing the wheel, it's spending money on a new wheel. Your transmission goes pop, and you work with the performance shop to solve that problem.

It's a really expensive hobby, but to be honest, a 500hp minivan sounds kind of cool. I wouldn't spend my money on it, but I think it's cool

i would be concerned with tuning. I’m sure some shop can slap the blower on but tuning it so it’s driveable will be the biggest issue. Everything is electronic on these things. For what it’s worth I have a supercharged Chrysler 300 (6.1) and I mentioned the Pacifica and they mentioned tuning issues since they would have to “figure it out” and the computers are probably “locked”

This MIGHT be worth looking into - I have no experience with them.

Some engine computers are just not supported in the aftermarket, but I would bet that the pacifica is. Don't know, but "think."
You also have to consider the transmission doing what's called "exploding" or "failing" if you add 50% more power to your engine. It's a consideration.
Biggest obstacle will be packaging, or what's called "this may not fit."
A procharger dealer does only custom supercharger installs, so packaging, as long as there is room, is not anything out of the ordinary for a dealer.

I used to rebuild and balance turbochargers, so I know about these kinds of things. Most of the time, money solved all engineering problems, unless they didn't.
A shop I worked with and was friends with had a guy bring his new (at the time) wrangler to them to supercharge. He supplied a lot of the kit and told them, yeah, it can be tuned. After they got the supercharger fitted and running, when it was time to tune, guess what, it couldn't be tuned. Whoops.

Go to Dealer Locator and then show up (don't call, they will not take you seriously) at the nearest procharger dealer. Expect to spend $10k. I don't know if the pacifica can even be tuned, which is what you would call an "obstacle."
[/QUOTE

We STOLE the Pacifica. All limited options except s, 8k old man miles.
A 35k check and my king ranch we were going to give away.

The 10k wouldn't fit had I bought it at retail.

Word from ripp;
They think it's overkill but will keep me in the oddity folder.

Can you imagine a blower builder ever saying overkill?

I'll not do the rabbit hole thing. Building the accessory drives will be intolerably hard (a guess). ****, it might just bolt up, but too many jeep guys throwing money at jeeps for shops to be bothered with anything more than r&r jobs.

It just dawned on me from what was said above:
My 2018 v10 ford has a parameter in the computer that disallows 100% throttle. It actually goes to just over 80% and stops. There is an odd value where you hold the pedal to the floor for 60 seconds while under load and it's almost feels as if carb secondaries(it's injected) kick in. A big whoosh sound comes in and it regrabs the transmission.
Has anyone ever really explored our computer settings?

I considered one. I'm sure it will be part of the blower upgrade if it happens.
I'm still a little unsold on pedal commander.
In my considerably sized head the pedal commander simply changes 3 inches of pedal travel vs acceleration to 1/2 inch of pedal travel vs acceleration and a small bit of added timing advance(I'm not even sure timing advance is really possible on our engines. What I don't know about modern engines represents the entirety of modern engines)
I'm sure I'm wrong on this pedal travel and am still checking value.
