Supercharging

You know your truck is slow when you have to hit the nitrous to get up to speed on the freeway lmao!

 

Yeah, I thought it was argumentative so I deleted it. Sorry.

So, in your opinion, a huge gain in usable power for $8K (it's actually less) is terrible. What's a better power upgrade for these vehicles?

I guess it's relevant because there are no other options to bolt on that kind of power for these vehicles.

In the end, it really comes down to opinion. If you don't really want more power, it's not going to be worth $8K to you. But, if someone really wants a serious power upgrade, it might not seem so bad.

 

I was actually pretty impressed the first time I actually floored it to pass someone. I'm still happy with the acceleration, but I could see better gearing and/or a little more low end torque being nice.

 

I think it's absolutely worth it if you have to drive long distances all weighted down for camping/overlanding. It's on my list of future / wish list mods.

Loaded up 4runners are SLOW AF.

 

I’m still bone stock so the power doesn’t bother me at all. My last 4Runner was an 87 sr5 with a 22re, I could barely make it up hills lol. pedal to the floor I would drop speed pretty quick.

 

Haha!

I do think it has a lot to do with experience and expectations. Even though my '03 had more torque, this one pulls harder when passing. And, it's a rocket compared to my '94!

If I compare it to my Chevy work truck, it's a dog. But, it also isn't likely to need lifters before 50K miles, either.

I think a tune and/or regear would satisfy most people.

 

Agreed Regear and a tune will probably satisfy most people who feel the power is lacking.

 

This seems like a better deal...

 

Thought it was like 60hp gain...that's nowhere near 35%...closer to 25-27% (at the wheels)

One huge benefit to the incoming 4 cylinder turbo will be that once it can be tuned, there will probably be decent gains available because you know Toyota is gonna be super conservative with the factory tune.

 

People are probably just going by what the website says. But, an increase of 65 HP is actually only ~24% of 270, so that makes it even worse than you said.

 

you’d get as many opinions as people commenting on this thread. It’s everyone personal choice , if you already think it’s expensive why take additional risk of issues with warranty? that would be my choice.
it’s also curious that you are thinking of supercharging a vehicle you just bought. Did you not take a test drive, prior to purchase? Maybe if you wanted more power 4R wasn’t the vehicle for you in the first place.

 

Let’s be honest.

The 4R has enough power. People are impatient and have gotten used to other vehicles with more.



If you get the twin turbo V-6 Bronco, it is faster at high altitudes. But not as much as one would think.



Meanwhile, it’s about the same as a Wrangler.

But these are not engineered to be driven fast. The brakes and suspension quickly become the weak points.

Maybe just buy a used Mustang for when you aren’t hitting the trails.

 

Any engine/transmission/engine computer/driveline issue you have will probably get denied if you’re supercharged, no matter what people will tell you about the dealer needing to prove the mod caused the failure.

 

I understand your position, but just because there are no "better" options does not make this one good. It's incredibly expensive for the very modest power gains. If you need it - others have mentioned towing - then it's the only game in town and you have to get it. But from a $/hp perspective for the "fun factor" it's terrible.

 

When it was worth it but I had to add a smaller pulley. In my case I think the tune was just too rich so it wasn’t consistent and it would let out black smoke on the 1-2 shift.

That’s in 4wd or else it would just one tire fire into 3rd or 4th.

The gains per dollar seem pretty average to me. What are you comparing it to?

Also, just because you think it's too much money for the gains doesn't mean it's bad.

Seems like the folks who have spent the money have been satisfied.

 

- Affordable
- Fast
- Drive anywhere capability

Pick two.

I get that "affordable" is relative - but lets say ~$50K, or less. Hard to get around this "rule" - if you are talking about buying a new vehicle. If you buy a decent used vehicle and can do the necessary mechanical work yourself - you could maybe get there and have a reasonably reliable vehicle.

 

The gains are not modest. And as far as HP/$ is concerned there is worse ways to spend your money.

 

What I'm comparing it to is the 7 supercharged cars I've owned since 1991 - some centrifugal, some PD. All were in the 45-55% range for power increases. Yes, they were V8's, but that doesn't matter because we're comparing percentage of gain. And in today's dollars those kits were and are still cheaper than the 4Runner kit. Have you ever owned a car or truck with an aftermarket supercharger?

But you seem determined to win this argument, so you win.

 

hey guys I don't really think there's an argument here. All the S/C I've seen int he past for the most part were about 50% gain.

However there's nothing else you can do to the 5th gen 4Runner to get the ~30% gain. It's really the only option. And TBH I prefer less gain myself because (hopefully) there's less a chance to run lean and wear the engine out prematurely.

So being the only easy kit option, there's really nothing to argue here.

 

Would it be much easy is buy something like 2024 Land Cruiser i-FORCE MAX turbocharged 2.4-liter four-cylinder 326 hp, 465 lb/ft. of torque or Tundra & Sequoia i-FORCE MAX 3.445L Twin-Turbo 437 hp, 583 lb/ft of torque. 4Runner should be there soon. So more power with factory warranty and service. Comes with CARB emissions compliance. Won't complain about wheels, tires, bumpers, racks, etc..

 

Just asking. No, I have not.

Sorry if I am too argumentative.

Is it possible that the standard boost is just a bit conservative on the Magnuson? Maybe a pulley upgrade could yield a better result?

I believe it comes as set at 6 PSI.

 

yeah this is why I am super excited that the new Toyota vehicles, Tacoma etc are turbo. you can simply buy a cable and a tune, flash it on there and probably get a very cheap extra.....just going by what you can do on a Civic flash.....approx 25-30% more power.

Ideally Toyota would require regular fuel on the new Taco/4Runner etc so there's room to increase the boost ad then use premium after the flash.

 

@EG2620 - you asked and you got!

I reflect on my choice of adding the SC and yes I probably should have gone for a GX or LandCruiser after all the crap I have added to my rig. BUT......I have to say that I have learned a ton of stuff I had no idea about before. I have also enjoyed the process of seeing how one mod after another one makes the 4R different and that to me is worth it, especially if I am using the modification consistently. And the whine from the SC makes me laugh from time to time.

 

Honestly my first thought is that our engine has got cast pistons, and rods that are probably incapable of handling any more than 6 lb of boost. I don't know that for a fact though, maybe somebody else can chime in with that.

 

Out of the box it's 6psi so a pulley down made 8psi. There's two more sizes down for 12 total psi and the fastest DCSB Tacoma ran it without issues except for when he oversped the engine through tuning. Of course this is the single VVT-i variant of the 1GR.

As far as piston material goes, I don't remember.

That's actually a very efficient set of runs given the MPH. He's using every bit of the hp that engine is making. Not much room to improve given the mph. Thanks for posting those.

 

Except that even with a SC the 4runner isn't fast. It is quality though so where is the option of expensive and good?

 

Not for $8k. What world are you from
