Magnuson Supercharger for 2010-Present & 2010-2014 FJ

100% sure that is not the issue. It can be seen on logs. AF is perfect. Throttle closes timing goes to nothing. No knock....

Now can the fuel pump go lean in some scenarios... possible. But what they are experiencing is torque management.

Fuel pump changes are a double edge sword.. you often end up with pickup and cativation issues on low tank conditions. There is always give and take with each modification. Hot fuel is also a big factor. The more you pump the hotter the fuel gets. It's complicated for sure. I think a pump booster might be a smarter solution.. but not sure if the Toyota pumps run at constant voltage or not.

The engine typically has less load in lower gears BTW...Max load and fuel demands will be in 4th gear. But the driveline sees the most stress in first gear from torque multiplication.

I would guess the URD piggyback would eliminate torque management by ignoring the ECU signals. But you have to wonder how it manages shifts and protects the driveline in other scenarios. Shifts are a big deal. so hopefully they got something for that, otherwise the transmission is not going to last.

Thanks for that info! Learn something new everyday.

no issue with my URD kit. WOT at stop, and it goes..

Curious, and I wondered if this was the case. Esp since they use a different method of engine management and make more power.

I'm curious if the same tq management occurs in 4x4. Or in the Limited model if anyone has it with a SC. My hunch is that the weak link that dictates torque management is the rear diff. That has been my general theory of why v8 models only come in awd form with the 8.2 rear axle and also why the MT FJ Cruiser also only comes in awd. The rear end can't take the additional torque even if the transmission might be able to. Just a thought that it may be different in 4hi than in 2hi.

I have not noticed the tq mgt in 4Lo or even 4Hi.. but then again. I'm usually too spooked to slam the throttle from a dead stop in those modes. I have done WOT pulls from a 20mph roll in 4wd and no noticeable tq mgt beyond shifts and downshift (which both feel very normal). Have never went WOT in 4Lo though. It does feel very responsive... just never gotten into much boost.

Also, it really is not a big deal even in 2wd. You can throttle around it in 2wd. You just have to learn not to slam it to the floor from a stop until rolling a certain speed and then it basically has very little impact beyond limiting wheel spin. Over 20mph and it is pretty much out of the picture.

The purpose of the supercharger in this bloated beast is TQ, pulling hills... It dose that fine. If the application was burnouts, drag launches... it would be very annoying. I think the power it adds is pretty much the limit for the drive line having any chance of long term survival with all the weight and tire sizes most people run.

Like I said before, it bugged me during the initial testing/pilot. I logged it in detail and discussed with magnuson several times. If you go back and read my orginal install thread I'm sure I mentioned it several times. I Have not encountered it in normal driving situations as I'm usually trying to keep my tires intact anyway. I also leave traction control on for most driving. It's a PITA to turn it off everytime you get in and really no reason to mess with it.

The issue with first gear is torque mgt in the ECU trying to protect the drive-line for longevity it kills timing and closes the throttle when it thinks too much multiplied tq is being applied. Similar thing happens on shifts. I've only seen it in first gear.. maybe a tad in second.

I would not say it is impossible to calibrate out or dial back... but they are not going to want to remove it for obvious reasons. It should in theory keep the drive line together. It bothered me at first when I was just playing with the truck being stupid. In real driving situations it never comes up for me.

Agree here, not relevant in most "real" driving situations. That said, not having a better get up and go hard off the line capability is a surprise, it was not expected ("advertised" by Magnuson) and feels very dramatic when it happens. I would actually say it is worse than stock in this regard because it just did not happen stock.

I posted my conundrum in another thread, but I'll summarize here and then add some numbers;

I am looking to buy a 4runner, but the conditions for doing so almost dictate I add an SC to the mix.

I live in Colorado, so mountain driving is a part of life. The ability to change lanes into faster traffic, from say 35mph - 50mph or higher, and do it with a fully loaded SUV on a 6% grade.. it's a normal thing here. Sluggish V-6's make it harder.

The response to this so far (and my thoughts) seem to drive me away from Toyo to the likes of the Lexus 460. Well, I did a few maths...

4runner stock
270 HP, 278 Lb-ft

Magnusun numbers with 6% boost
351 , 356 lb-ft

Compared to the Gx460 stock numbers
301, 329 lb-ft

Seems to me that a tweaked 4runner would get me more than the 460. And those numbers are at sea level. It's still a ton of dough to lay down on top of buying the vehicle, but maybe it's the better choice.

The other problem with buying a 460 is that the grill of the new ones look like the car is trying to do La Macarena.

V8 4Runners were available in 2WD though.

Edit: I did find at least one person who claims to own one. So it looks like they do in fact exist. I'd be curious if they have very heavy torque mgmt intrusion also.

I have a co-worker who owns one.

I don't think he'd be one to notice that kind of thing though.

Sounds like the conditions that are required almost dictate you buy a different vehicle. It's only a conundrum if you make it one.

I should be able to tell next week when I get delivery

It's on an new 2018 LE and the dealership is finishing it up today and then they are putting on my lift (keeping stock tire size and it's only a 2/1.5 mild lift).

I will agree with others that have an S/C...I don't plan on tramping on it from a stop. I had a 2011 Tacoma with the TRD S/C and it became the truck that I should have kept... I never stomped on that one from a dead stop either, nor did I go deep into the throttle during a shift. Hoping this setup exceeds my expectations because my 2011 was really great and I kick myself for not keeping it.

Be careful. A guy near me had a dealer install one and they somehow forgot or claimed the tune part did not work. Pop went the engine.

After further investigation stock tune was still in place. They did put in a new motor for him... but now that has issues. I just don't ever trust dealers to do this type of work.. but then again. I don't even trust dealer techs to do an oil change.

Hopefully, you got someone who actually pays attention to details. Rare, but it does happen still from time to time.

Oh believe me... after my Tacoma S/C installation from a dealer "claiming" they have done many.... I learned my lesson. Big time...

The master tech doing mine is on a sprint car team and is the master mechanic. He's S/C'd Mustangs, Tundras, Tacomas and FJs. This is the first 4Runner...but basically the same.

In addition, when he uploaded the file early yesterday morning (registering the VIN and device) eastern time to Magnuson the web response was "we will get back to you in 1 or 2 business days". He left a voice mail (about 5AM Pacific) and I waited until they opened and placed a call plus emailed Jesse (Director of Marketing and Sales for Magnuson) and low and behold...the tech had the tune about 10 minutes after 8AM Pacific time. That's pretty good considering the time zones. The tech told me that's about the only difference between the TRD and Magnuson installs. The tunes were already available to Toyota dealerships, where this one had to be downloaded from Magnuson.

And I'm with you on dealers. I do all my own maintenance. In this case, I'm not "ASE certified" and I like the 3/36K Magnuson warranty. Plus...I didn't have all the tools and likely would have taken me 3-4 days in my garage. I read the installation book and I felt I could do it, just with the above points I decided to sub it out.

Are you all running the stock intake or something else?

Stock. There is a different tune you have to apply of you switch out to an aftermarket CAI. Or you could start with one... either way Magnuson has a different file depending on what you have.

 

[eHaze]

It's my understanding that a N/A 4runner gains almost nothing from an aftermarket intake, other than the noise it creates. Having had a K&N intake on my other 4runner I can say it was a total waste of money.

Now, with a supercharger on a 4runner, I can see the need for a more free-flowing intake setup. But, I thought I had read a post/article that stated Magnuson tested the TRD intake and it resulted in no gains. Does this sound familiar?

 

[Havik]

Are you all running the stock intake or something else?

Stock with an aFe dry filter and an ARB/Safari snorkel.

Magunson Supercharger 3 months

I had a Magnuson SC installed only my 2014 Limited.
So far so good. Here are some of my thoughts:
Overall I'm happy with it. Love the "vacuum cleaner" sound when I punch it.
Gas mileage not too bad. Loss of about 1mpg if driven hard. I do have to put premium now. No mpg loss when driving Miss Daisy. It will not beat a Porsche on a drag race, but can definitely feel extra power.
No issues (so far). Mechanically speaking. Is it a must get? No. But if you have the funds and enjoy the additional power, go for it. It works. FWIW, I don't go around hot rodding, but I don't hesitate to punch when I need/want to.
SC was installed by 4WheelParts of Norcross, GA. Excellent work.

 

[eHaze]

When I drive my other 4runner I really notice the lack of power. Then I jump in the supercharged one and really appreciate the extra power.
