ARCHIVE 100-series Performance Intake System

[NKP Garage]

We just finished up a long week of development work on some new goodies for the 100-series Land Cruiser and LX470. We've finished up our headers and also a new performance intake system that we will have available for you guys soon.

Here are some teaser photos of the intake system we have built for you guys. Please excuse the bad photos. These were just some quick photos during our prototyping work last week.

The intake system will include all 4 ports to connect OEM vacuum lines to new intake, silicone couplers, 4 new high temp silicone vacuum lines to replace the 4 that normally go to the stock intake, stainless steel clamps, high flow dual inverted velocity stack custom filter, "air box", all mounting hardware, detailed installation instructions, and our usual lifetime warranty that comes with our other intake systems.

Enjoy!

Will you have before and after dynos of everything through the ENTIRE RPM range? I don't like it when I see exhaust manufacturers (Magnaflow) discard the first 1/2 of the range because of a low end torque decrease and measly high end power increase.

Is that a dry element?

Yes, of course.

The one in the photo is an 8 layer oiled filter (similar to K&N). We will have both oiled and dry filter options for you guys once they're ready for sale.

Can you explain what might be the differences / advantages of dry vs. oiled filters?

 

[petrotk40]

Will you plumb the intake to reconnect all those hoses that are on the stock intake box?

Generally, like for like, a good oiled filter will out flow a dry filter and perform better. These are all lifetime filters that are cleanable and reusable that we use. When you are ready to clean and reuse a dry filter you just rinse it off with the appropriate washing fluid, let it dry and reinstall. With an oiled filter you rinse it off with the appropriate washing fluid, apply fresh oil to the filter and reinstall. The problem with oiled filters is that the end user will sometimes put way too much oil on the filter after cleaning, and then the extra oil gets sucked through the MAF and causes problems. If an oiled filter is cleaned and re-oiled properly then they function extremely well.

All in all, a high performance dry filter and a high performance oiled filter will both work great on the 100 series. We will offer both so that you guys have a choice of which you want to go with on an intake system for your truck.

Yes, all 4 vacuum hoses that normally go to the stock intake go to the new EMSPowered intake pipe. Included will also be 4 new high temp silicone vacuum hoses in the proper sizes and lengths to go from the factory location to the new intake pipe.

I have a question about the ability of the ECU to accurately compensate for change.

So given this example:

Stock 2002 LC
1) Your new fangled Intake system
2) Your New Fangled Long Tube Headers
3) Your New Fangled CatBack Exhaust system

Add up all the gains that will be claimed for these mods and it will be a significant increase in TQ and HP claimed. You'll have pretty graphs to back all this up.

How does the ECU have the map to compensate for this?

How does the ECU have the map to compensate for this safely?

All these mods will tend to make the mixture go lean, or they wouldn't be doing anything in a positive direction.

The ECU has a few main fuel and ignition maps, and also has a few trim maps based on coolant temp, knock sensor inputs, air temps, and O2 sensor readings. The factory ECU also has other parts of the map that are setup from the factory for boosted applications such as a supercharger. All in all, the factory Toyota ECU's are setup to be very flexible.

More power is had by freeing up restrictions to get more air volume in and more air volume out as efficiently as possible. Part of that is by freeing up the exhaust side with our high performance headers, our high flow mid-pipes, our high flow cat-back exhaust, and on the intake side with our performance intake system as described in this thread. More air in, more air out, more power to the ground. The MAF measures how much air the engine is ingesting, the O2 sensors measure air fuel mixture, and the ECU adjusts for the changes accordingly.

You either got these products developed just in time, or almost just in time. Ive got $$$ burning a hole in my pocket... with time constraints. Excited to see (the rest of) these products on the shelves for us. Excited to see what Rob writes up in the next couple weeks as well. EXCITED!

 

[TwiceWithHair]

^^ my silver star is gone! guess ive been here a while. gotta re up!

 

[SHAGGY101]

Like the man said, the ECU has a base map correlating load to RPM then correction factors are applied to this basic map in order to correct for different scenarios based on feedback from the many sensors in the engine. For example, you do not need to re-tune EFI at higher altitudes.

 

[petrotk40]

baktasht, do you think there is additional gain to be had in re-mapping the ECU after installing new intake, headers and exhaust?

 

[SHAGGY101]

Don't think it can be easily done as some american vehicles can. Read.

I'd buy one if it's snorkel compatible

Are we 100% sure on that? Toyota is notorious for mediocre stock ECU mapping variability - it compensates for basically everything and achieves as-close-to-stock-performance as possible.

Yes, there is additional power/torque to be had with tuning, probably around 10-20whp. BUT, our opinion here at EMSPowered regarding tuning Toyota ECU's based on our experience over the years is that you are better off leaving the ECU alone. Modify within the limitations of the factory ECU and factory fuel injectors and you will have a much more reliable vehicle that will start everytime no matter the weather temperature, your truck will run on just about any gas you put in it whether it is 87, 89, 91, 93, or 94 octane without problems, you will have a reliable running truck no matter what elevation you are at, etc... Toyota spent millions of dollars tuning these vehicles so that they can be driven anywhere under any conditions. A "mail order" tune or even a professional tune on a dyno will never be as good and as flexible as Toyota's tune.

Our view here is that as long as you are within the capabilities of the factory ECU and don't require larger injectors for your setup, leave the factory ECU alone and let Toyota's millions of dollars in development keep your truck running strong and running long. If your modifications require more fuel than what the factory injectors provide (ie, big turbocharger) then it would be time to upgrade your fuel system and your ECU to one that is fully tunable.

I'd buy one if it's snorkel compatible

This intake is not snorkel compatible. If there's enough interest for at least 10 kits we can build a snorkel compatible version for you guys as well.

That'a actually true in a non-flexible way.

Toyota ECU's are setup to work in various environments and fuel conditions by defaulting to pouring fuel into the mix--whatever that fuel might be.

That is pretty much the default for their truck and SUV applications--esp. the LC flash on the ECU.

It's been the same for a very long time...
