Recommended intake system

NOTHING is going to get your mileage back. That is the price for bigass tires. You can have either, not both.

Performance increase is placebo effect.

Let's be clear: NO intake alone is going to make a performance difference on these trucks. They primarily change the engine note to make it more pleasant.

Snorkel will improve gas mileage, but not to where it was before you lifted and added tires. You also get the obvious water-fording advantages.

Other than that, you have to move up to supercharger for performance increases. And that'll suck even more fuel - premium fuel at that.

 

If you have "big-ass" tires and have lost some perf/mpg,,, a re-gear might be your best bet. Possibly consider some headers. An intake "might" get you 3-5hp at the top end of the rpm range,,, hardly noticeable, same appies to a catback if you are so inclined. You also might consider a MAF calibrator, especially if you're set on a Volant, but be aware that this only makes an improvement when in open loop (close to WOT, or cold engine, for the most part).

There's not alot of NA improvements on this engine that are noticable gainers. An APR X-1 is not an option since you have an '11.

 

well thanks for the advice, not only was it helpful but it educated me as well. Im not gonna lie, I am new to this whole scence so im starting to pick up things as I go.

 

stock box with a decent filter, (K&N, TRD, AFE-dry)

 

Side note, since my OBD reader came in i've been monitoring my S/c'd Fuel Consumption, not sure how calibrated it is but its reading about 23.5 MPG's

 

If we are talking about the 1GR-FE 4.0L V6, then that statement is completely in error.

On many engines these days there is little or no increase in power when an aftermarket air intake is installed, but that is not the case on the 1GR.

When URD got our 2005 Tacoma, I immediately started looking for the "FREE" hp mods that I found for the older 3.4L V6. All of that is detailed on my website www.GadgetOnline.com.

I got on the dyno and started running tests and tested it without the big main tube installed. No gain in power. Tested it with the lid off of the air filter box. No gain in power. Tested it with the carbon trap removed. No gain in power. Tested it with the lid off, the main filter out and the carbon trap out, NO GAIN IN POWER.

It was very clear that the stock air filter box its self had to go. It makes sense if you really look at the design of it. The air has to make several sharp turns in there before it gets into the engine. All these turns makes so much turbulence that Toyota had to install a flow straightener before the MAF to calm things down to get a clean reading. All this adds up to a significant flow restriction.

This led to the development of the URD TCAI. On my 2005 XRunner it gained around 18 RWHP over the stock air filter box and the faster you drive it take advantage of the increased dynamic air pressure that builds up in front of the vehicle to force more air into the engine then would normally be pulled in for more power.

The URD TCAI was intended to be a street performance intake and it is ideal for the XRunners. If you are an avid off roader and go through creeks and streams it is not the intake for you. For you guys we have the aFe Stage 2si intake.

aFe used to make the intake system for TRD and it is a very good intake. I tested that on my 2006 4Runner with the 1GR and the gain was 12 RWHP over the stock air filter box and we keep a large stock of these intakes with the ProDryS synthetic filter on the self at URD.

Those are the two intakes we recommend the most. There are some others we have gained experience with over the years and here are a few:

Volant- Nice design overall but there is a significant design problem that makes the MAF read very high causing the engine to run very rich killing power. Generally most with the Volant will have a loss of power over stock due to the increase in the richness of the fuel mixture. URD has a special program for our MAF Cal to address this. On one customer' truck a dyno test showed a loss of 15 RWHP with the Volant and after a retune with the URD MAF Cal the gain was 30 RWHP (15 over the stock intake only after correction).

AirAid- We have dyno tested this and there is no gain because they retain the stock air filter box and convert it to a hot air intake. They are basically just sticking a cone filter where the main air tube is and removing the filter media from inside the air filter box.

There are others that are hot air intakes, your basic filter on a stick and they pull in hot engine compartment air. This is not good for making power in general.

If I can help you with a URD or an aFe intake, let me know.

^^^^ This

Having personally owned both the AFE stage 2ci and now a URDTCAI, I definitely notice a difference in both

 

what did you do with your stock wheels of the tx?

 

... are you asking me??? and what are you asking

 

I know right?? Good, I thought my brain snapped and it was just me

 

I have them stored away. why do you ask if you dont mind me asking?

 

AFE Pro Dry Filter

 

auto anything

 

I will dissagree with you, with the right setup you can feel power difference and you will really notice it if you are stressing your motor under a heavy tow, and when my foot is out of it with factory tires im get average 1.6mpg better.

 

r
you could always change your gearing to get better MPG and change gearing on transmission to get more power

 

Correct. Without a tune it does run more rich. Due to the design of the system, and the diameter of the tube at the MAF sensor. It really wasn't well known what effects the Volant intake was having though, until the X-1 came out. With the ability to datalog the different sensors and comparing those with similar vehicles that had different intakes, the "issue" was quickly spotted. Thus a little fine tuning with the x-1 and bam. Problem solved.

So for TacomaG26, if you have an EMS you can tune, and a wide band gauge or datalog device as well, you can make the Volant perform even better.

Volant compared to stock, equal to less. Volant to AFe, AFe is better. Volant to AFe with a tune, equal.

 

Quoted for excellency in facts based off of testing.

Others personal opinions are usually lacking due to strictly being an opinion based off of misinformation. Not all things are equal on all platforms and thus cannot apply universally.

 

Thank You

 

I had a k&n before and then got the AFE and noticed the difference right away. The thing that I like about the volant is the scoop however there is a mood you can do to the AFE or first gen TRD. http://www.xr-underground.com/forum/showthread.php?t=18400
I guess we can call it coupes mod.

 

And I still have doubts about Ass dyno's not being valid, I drive over 100km's per day minimum, sometimes over 1000km's, if something in my baby changes, your damn right I'll notice
