TRD supercharger?

just a rant. BUT there was never a FACTORY 22RE-T BUT there was a FACTORY 22R-TE. If anyone ever puts a "T" at the end of a Toyota Engine number then it was turbo-ed after it left the factory like a NA to T. That's why is called 2JZ-GTE and not a 2JZ-GET unless you bought a 2JZ-GE and then turboed it then you could say 2JZ-GE-T cause your turbo-ed it.

sorry for the rant I just noticed alot of people on forums refer it at a 22RE-T when that motor never existed and wanted to clear it up.

 

Oh, the good ole days....I had a 1990 white 4x4 stripy base model....Came with the tiny steel wheels, and no back bumper. Best freaking truck over.. I ended up trading it in 3yrs later.

 

Has a supercharger been identified yet?

 

I don't think it would work well at all on a Atkinson cycle engine. See the Atkinson cycle holds the intake valve open part way thru the compression stroke, so a Supercharger or Turbo will not be as efficient

 

False

Atkinson cycle + supercharging = Miller cycle
https://en.m.wikipedia.org/wiki/Miller_cycle

Toyota already has a turbocharged Atkinson-capable engine in the Lexus NX200T

 

I posted the response from Magnuson that indicates a supercharger for the 2016+ is in development. If people started harassing them maybe development would get moved up?

Or did u want 3.4?

I mostly just wanted to verify that the rumors were true

 

Probably if by bugging you mean a group buy was setup with like 25 people putting up a $500 deposit, sure. Itll be hell to get it CARB legal without bringing up the costs and even the last gen TRD supercharger couldnt do toward the end of the run... and it had an issue with chewing up belts.

 

I'm in for group buy

 

I would be interested in a group buy

 

I would be happy for a proper map of the ecu to get rid of the low end lag and odd computer behavior. damn epa nanny

 

This is literally the entire concept of a Miller cycle engine. Look it up, the miller cycle was designed to maximize the efficiency of an atkinson cycle by putting constant pressure on the intake system. The atkinson cycle engine has a problem of allowing intake charge to leak back into the intake because the atkinson cycle allows the intake valve to be open during the compression stroke. If you add boost behind the intake charge, no more leak down during the time that the intake valve is open and compression is building as the pressure from the blower equals or exceeds the pressure in the cylinder at the beginning of the compression cycle. The result is not only greater efficiency, but much more power, and MUCH better throttle response.

Think about it this way... the engine we currently have makes the most power beyond 3500 RPM but best mileage around 2000 rpm. If you add a supercharger, you will be making more power at a lower throttle opening, so the real world difference will be you won't have to push the pedal down nearly as much to move the same amount of truck as fast as before. Less pedal pushing means more MPGs. Now, if you're like me and you can't help but want to push the pedal, then you likely will forego all the potentially better mileage, but you WILL be making a lot more power and having a lot more fun doing it most likely.

A turbo application would probably help with making more power, but I believe a supercharger would be superior overall. The turbo would not be beneficial with throttle response, as the blowoff valve is going to dump all the boost when you aren't on the throttle, so it won't be providing CONSTANT boost on the intake tract, but rather it will be providing lots of boost when you're on the throttle and negative boost while off the throttle, meaning it would greatly exaggerate issues with throttle response, as well as likely making problems people have with rev hang between gears much worse. A supercharger would smooth out all these problems by providing at least a little bit of constant boost, even at idle

 

How would that make it more efficient? Isn't that the point in leaving the valves open, to lose some compression? Seems like if it's pressurized to where that doesn't happen, then what was the point in the first place? Maybe I don't understand all the dynamics, I'm far from an engineer. Although this idea does suggest we can boost these motors anyway

 

It makes the engine more efficient because it forces all the fuel being pumped by the various injectors to stay in the cylinder, rather than getting recirculated back into the intake tract. Forcing all the fuel in quicker means that the O2 sensor is going to think that the engine is running significantly richer because all the fuel that before was sitting in the intake tract is now being forced through the engine quicker. The system will compensate for this and allow the engine to run slightly leaner most of the time.

The purpose of the 'atkinson cycle' is to make the effective "volume" of the entire cylinder smaller. While the entire overall displacement of the engine is 3.5 liters, if the intake valve is opening later in the intake cycle and more into the compression, then it effectively is not cramming as much fuel into the cylinder before compression begins, which means it overall will use less, as the engine is acting like its essentially a 2.5 liter during this moment as it is only filling a certain percent of the cylinders total volume. Adding boost behind the intake tract at this point would only ensure that no cylinder volume is allowed to leak out, meaning that the intake will be smoother and not disrupted by the 'back and forth' motion of air leaking backwards in the intake.

 

Also, its probably worth noting that seeing as this engine has VVT-I and the atkinson cycle component of the engine is strictly in software, that component of the system could potentially be tuned out as necessary for aftermarket purposes. So for those who are really sold on the idea of a turbo taco, "let her rip".
But for those of us who want more power on tap, but more efficiency on the daily then seriously petition magnuson to adapt the supercharger to the taco. Petition URD to make a rotrex kit for the taco. Ive already been going back and forth with Gadget for a while on this subject and I've been assured that there are plans for lots more upgrades for the taco in the not so distant future. Apparently, after the 4runner TB adapter plate and short shifter (both already released), transmission mods are next up. Look for an aftermarket clutch kit soon that will be strong enough to handle boost, that will be the real clue as to their plans. If they build clutches designed to handle 400+ HP, then you guys will all know whats coming next

 

Damn it, now I need to change my underwear. Even a low boost option would make this truck amazing I think.

 

I know right?? I've lost some sleep already contemplating the possibilities bro! It would be EPIC. Now we just all have to band together and let the aftermarket companies know, "I have money for mods, take it now!"
