Admin 3" Long Tube Intakes
 

Anyone have any experience with the Admin 3" Long Tube Intakes?

AdminTuning Infiniti G37 Nissan 370Z VQ37VHR 3" Long Tube Intake System

------------

I was talking to Eddie from Real Auto Dynamics about CAI today and he mentioned this system. I hadn't come across it from my research here on the forum, but after he mentioned it I did come across a post or two. Hoping to hear more about it.

I'm really SHOCKED given how everyone on this forum says: "the stock airbox is engineered to flow very efficiently"

Which makes me wonder:

A) The stock airbox is bs and so are the above claims

B) The Tune is really where the power is made, which could be accomplished on both the stock airbox with some dropin k/n's, and if so, then whynot just skip the intake and just get a tune entirely, especially if you can get 85% of the same result and keep the stock airbox???

C) An aftermarket intake actually is NEEDED with a tune in order to see real gains.

Someone please educate me on this, as last time I looked under the hood, it's not an 8.0 ltr Viper motor sitting there.

I don't think most people on the forum think that. If you look at the list of performance addons by forum members it is obvious that a CAI is one of the first to do.

Actually, there's been more than a few dyno sheets that show that drop in filters and maf tubes paired with the stock airbox will get you 90% of the gains of a long tube intake, at 25% of the cost.

I agree with your reasoning Chuck. This topic is about the Admin 3" long tubes however and I think you can't get the 90% of the gains with drop ins and maf tubes. I heard big numbers were gained with these even over other popular CAI's.
They are pricey though as you mentioned.

The problem with a 3" intake is the bottleneck at the throttle body. I'm sure these would show gains if you hog out the entire intake tract and then tune for it. Otherwise I can't see them doing much beyond a standard diameter CAI.

There is a fine line between velocity and volume. Go too big and loose both. Like the Chuckster said. You will have a bottle neck at the throttle bodies. Think the best bet to use these with enlarged throttle bodies to take advantage of them.

I see the EPS Throttle Body Upgrade kit is to 70” mm (2.75”). It would be great to match this with the AAM 2.75” intake . From there, what would be the next logical addition(s) ? I am new to car mechanics and only know what I've been trying to absorb through the forum.

I have been drawn in to going the route of Synolimit's kit with the manifolds. His throttle body goes to 63" mm (2.5") though. I am left with questions, due to my ignorance I assume. Perhaps 2.5" is large enough and not to worry about larger porting?

It's a rabbit hole I don't know if you want to go down. It gets pricey. After a cai, test pipes or LTH's ($), cat back, tune. That's where you pick up the most bang for your buck. After that, the prices increase greatly for little hp increase. When you have done the before mention add-ons. Next would be throttle bodies, port matching the intakes, cams. Do all of this. You're about 1/2 the price of a Stage 1 TT kit that will almost double the hp.

Thank you for your insight. I appreciate it.

Thanks for everyones response, apologizes if I derailed the OP. Personally I'm going for the pmaf tubes/k&n combo, save the $ for a tune.

More like an infinite hole

Once you start down that hole. There is no 12 step program for recovery. Just bankruptcy.

I have Synolimit’s setup with AAM’s intake on my car and I got gains with a tune. The key is matching the diameters so there is consistency in the airflow throughout the intake tract to keep the flow smooth. I looked at the EPS TBs and 70mm looked great but the manifold can’t go to 70mm and EPS uses an adapter to neck down to 58mm for the manifold. So where is the benefit? Synolimit’s setup is consistently 63mm (2.5 inches) which is as large as one can go. A 3-inch intake will not supply any more air than a 2.75 inch because it’s not being asked too (in a NA engine). The total vacuum demand starts in the manifold and whatever volume it can demand is all you need until you start forcing air.

It's the same reason I didnt jump on the EPS TB's. With the Z1 Intakes having a 2.5" inner diameter, it matched stock ported throttle bodies perfectly. Maybe if there was an aftermarket intake manifold with larger throttle body inlets.

It's all in the tune

A tune can only do so much. If there is a mismatched set of parts. It can help, but it still won't be 100%.

I saw a post of one of the guys in my local Z club (Central Florida Z Club) hit 350whp NA with admin tuning intakes and EPS throttlebodies

Someone on the FB pages is giving me his new 3" setup and i sold my stillin gen 3's. Guess it cant get any worse. I say that though but 3 times ive dyno'd changing things and ive lost power! Like a lot! Think my best was 312 SAE in 4th with my setup, 2.75's, LTH and dual cbe. Then i tried e85 and made like 298 SAE in 5th!!! So almost stock power in 4th. Now with the side exit cbe and stillen gen 3's i made 310 SAE 5th. So maybe i could use a bigger intake. Who knows. Im currently porting the heads, openening the SH*T out of lower manifold and then going to try the 3" intakes. Hope it works out.

keep us posted

Everything i've heard about the Admin tuning intakes is that they require a MAF scaling tune at minimum, perform the best with the EPS throttle bodies...which at this point you are now looking at $1800 for some CAI's and +22 whp gains? Maybe 40whp with the throttle bodies?
It also bothers me that Moncef, the owner of Admin Tuning will not post apples to apples dyno sheets of lets say a Stillen Gen 3 with a tune next to Admin Tuning with MAF scaling. Why? Because the results are going to be close and you'll be spending $1200 for what you could get for ~$900 (assuming you purchase used Gen 3 intakes).

The cost just doesn't seem worth it to me and pretty much defeats the purpose of a CAI, which is a low cost bolt on mod that gets you a little pick up.

Also, i'd like to point out that K&N drop ins or short ram intakes with a tune may get you within 90% of a CAI on the dyno...but try that in the real world with some heat and watch that 90% drop fast due to heat soak.

Short rams, absolutely. But you think that maf tubes and drop ins heat soak dramatically more than a long tube intake? I would think that, since it's still using the stock intake path (drawing air from outside the engine compartment) and it's all plastic/silicone instead of the metal long tubes that it wouldn't show as much of a temperature rise.

Plastic is a pretty crappy conductor of heat, pretty sure the aluminum tubing is going to maintain cooler AIT's across the board

Are you sure? Usually plastic has a much lower thermal conductivity than Al, so the long tubes would transfer more of the engine bay heat to the air within the tube. Granted, I'm not sure what type of plastic the stock intake tract is. I think the best case for an intake would be a long tube setup with the reflective gold foil wrapped around the pipe, but the way the factory intake is set up is pretty good for an OEM.

QUOTE=Eagle;3666928]Plastic is a pretty crappy conductor of heat, pretty sure the aluminum tubing is going to maintain cooler AIT's across the board[/QUOTE]

I think you're both on the same track, just going different directions. In this case, I think Chuck is correct... you WANT the non-conductive plastic inside the engine compartment because it will resist heat soak.... if the plumbing was seeing ambient air, you'd rather have the aluminum piping to dissipate any heat.

That being said, I don't think it matters much one way or the other when the car is in motion and the engine is eating. Thin walled AL tubing is not going to change the air temperature all that much I don't think.

It'd be a cold day in hell if you get that amount of power. People still run the same amount of power with all these setups. Nothing's really changing the game. Until we see consistent 340-350...360hp? Out of everyone just buy what you can afford. You're exactly right though! Tune probably costs more too because you do have to scale the **** out of them!

Which leads me to this question:

Who has the most reliable ecutech email tune available? Having come from the wrx world, it was easy to datalog and send a file back to the tuner for safety purposes, plus I was spoiled with Cobb being 10 mins away (I could walk there even!).

I care more about reliability instead of all out numbers/bragging/leaning out/blown motor, and reading the above posts doesn't exactly instill much confidence as far as I'm concerned.

I have the Admin Tuning intakes but I'm not here to defend Moncef either, although he's a great guy to deal with. I will say that most companies don't do comparative dynos for their products against a competitors by a third party; and if they did, I'd still be hesitant to believe them. Why hold it against him when he's a smaller business then Stillen or AAM?

The tune should cost exactly the same... Seb (Specialty Z) didn't have any issues with mine and I'm in Germany. I'll will add that I was able to drive my car without any CELs/etc. prior to tuning but I had GTR injectors installed at the same time as my Admin intakes and EPS tbs.

Seb @ Specialty Z hands down. Process is the same: data log, email, wait, upload, redo until perfect (took four times before he was happy with both of my maps).

I don't have anything against him personally but I certainly don't like false advertising. He and his fanbois claim they make more power than any other solution out there, but the catch is you have to pay for a tune and or buy throttle bodies to take advantage of a 3" intake charge pipe. Congratulations, you get to spend $1800 on something that should have been no more than $600 for a new CAI. For that kind of money I would much rather get a new set of Stillen G3's, an oil cooler and upgrade my brake pads. Outside of the 370z world even $600 is a lot of money for something like a CAI.

He's also pushing people to tune their cars after just doing the CAI which i think most people on this forum know is pretty stupid...unless of course you got money burn. Even if it is just MAF scaling, you're paying the same amount you would for an actual tune!!!

He may be a nice guy, he may have a decent product and know how to tune...but he is pretty bad about being honest with the community about what it means when you buy a set of Admin Tuning intakes.

As a old timer Z guy,I'll start with a apology.
Do not want to insult any other Z owners. But,this is how I see it.

For whatever reason,the intake is the first thing a new Z owner looks to mod after buying
the car.
Guilty-I did the obligatory Pop-Charger on my Z33.

Main thing I see about intakes and/or other go proposed "go fast" stuff is not the numbers. It is HOW the car's response is after you sunk the bucks into same.
For intakes,it will sound "sexy". That sound does not mean more power YOU CAN FEEL.
Trust me,perception is reality. You THINK it is faster. Bottom line,you will be using more fuel...
Intakes are not all that bad of an investment. Keep in mind,they are a component
or,a mix of parts to REALLY give you performance over stock.
Add HFC'S,exhaust etc. Lighter wheels--you'll have something.
Get a proper tune.
It'll feel that the car is "lighter".

Trust me

No need to apologize, I think you nailed it. Basically everyone understands that it's stupid to play the dyno game with cold air intakes. You just aren't going to make a lot of power, end of story. But Admin Tuning wants people to pay a butt load of cash for a kit that is not worth the cost...and then people are out there online thanking him for it and spreading the BS.

Agreed. To put it in perspective, I saw little gains on my 07 wrx going from a tuned/blouch20g to tune/cobb airbox/blouch20g. Basically what I learned from that was while yes there WERE gains, it was only because more boost could be made in a safer manner. Wasn't worth the $$ for the intake/air box plus another dyno tune.

This is why I'm skeptical about major gains with intakes with the Z being an N/A platform.

Thanks for the reply earlier, will request a quote from Seb :stirthepot:

Thats good if it does but i dont see why it should. Ive tuned before on my wrx. Completely Rescaling a MAF at all RPMs for complete drivability isnt a 5min job or even a hour. I can see a etune costing the same because they tuner isnt out driving the car, youre doing all the work.

Pablo Escobar had money to burn. Literally. One night while running from the police he and his family found an abandoned cabin where they needed heat and he ended up burning $2 million in cash. Pablo Escobar had a enough money that he could burn $2 million cash every night for 41 years and he would still have money.

I am in the wrong business.

Most of us are. :icon14:

We all are!

1) Monster cable
2) 5 hour energy
3) Tapout shirts
4) Beanie babies....
5) all fashion brands/fashion

All garbage, but people paid a HUGE markup for a "name" why? because most everyone in this world are followers, and buy parts/things not because of functionality, but more so because they want to LOOK or SOUND better/successful/faster/stronger etc.

It's sad really, because as soon as the "trend" or following shifts to a different product or fashion, all of a sudden those products are worth exactly nothing.

So, my advice: Don't be a follower, or learn how to sell to followers. Warren Buffet (I'm not a fan but I remember this quote) "I'm doing what the majority of people are not doing"

I had only intakes installed when I got my tune. The throttle response improvement alone made me think that I could have just done a tune on a fully stock car and been happy :twocents:

Of course, a few years later here I am still hanging onto a root at the top of the rabbit hole trying not to fall in. The re-tune for adding an exhaust was not expensive and done remotely.

You have to tune with just those intakes haha! You cant increase MAF size and have the car run.

This makes sense to me but It seems there is quite a divide by forum members as to whether this is the case.

I know I have gotten a few responses from some generous members on here regarding this. But I am hoping some others might chime in.

If some of you guys could start your intake build again from the beginning today. What pieces what would you go with ?
