I have read a bunch of posts about aftermarket air intake systems , and it makes sence to me that there is not much improvement over stock .
But I just saw a friends truck , and it had a Banks dual air intake , [ all the others I've seen were single ] so the ??? are back , about how much improvement .
Insted of one air horn going to the stock intake , the dual replaces the hole plate on top of the cast to head manifold , with 2 air horns .
This looks like it could do better , anybody done any testing , Dyno ?
With the older single the improvement wasn't enough to justify the cost for everyday driving , if there is enough improvement then I may look at this again .
Thanks John

 

Stop right there and save your money. This is just another example of a Banks product that looks cool but doesnt perform enough to justify the cost if you ask me. And I dont think you have enough power/fuel to need this kind of upgrade.

My .02

 

I was hoping for a more informative ya or na ,
Some testing to show one way or the other , at what level does a mod pay for itself ,
If I am asking about a mod , then I'm onto moding , so just the truck as in my sig. is not the aplication , the aplication is with other parts / a system of parts tuned to each other for the best performance , in this case a daily driver mild towing , mountains .
I do mean to shoot you down , but I look for info / facts for decisions like this .

 

Well I believe that it has been established that this part is not worth the money that is required to posses this mod. You do not see many of them. If it was worth it, then you would see more of them in the sigs. Flat out it would take more than just a double intake to make these breath better. And that would have to be between the intake and the compression chamber.

 

Respectfully, it is my opinion many of those who speak against the TwinRam Intake have NO first-hand experience with the product.

I believe many of those are so full of what "I heard" or "My friend says" that they are simply not willing to consider otherwise.

So be it, we'll see them race day.



On to John Faughn's initial question:

The TwinRam intake is superior to the stock, OEM intake horn as it flows substantially more air all else being the same. It is superior to most aftermarket intakes in that it allows use of all OEM heaters and sensors in the dual feed setting.

With my installation, I saw a notable drop in EGT's (not a lot, but still there). The engine definitely breaths easier. Especially in higher boost conditions, but note, when in lower boost conditions where the engine acts more of a naturally aspirated engine, the EGT's are down.

Because our engines use intake heater grids to aid in clean, stable cold start and run conditions, the TwinRam Intake has one separate the OEM heater grids and install them in the individual horns allowing full and normal operation.

If you have to deal with strict local or state emissions inspections, the TwinRam Intake comes with a CARB certification.


Above all, As part of a complete, free flowing charge-air system, the TwinRam intake is absolute best. By itself, . . .. not so much.

It adds absolutely NO power by itself.

But when combined with a larger turbo, better after-cooler, and larger plumbing, it aids greatly in improved breathing capabilities.

Add more fuel to that, and you get much bigger power, if not substantial EGT control when working the truck hard.


Is it expensive? You betcha. But in the end, I think it's worth every penny.



Flick your Bics fan-boys . . . . FLAME ON!!

 

IMHO the stock (single) intake horn can outflow what the stock cyl head and cam will allow into the motor so until that part is a restriction than its worthless to change. I also feel that Banks wants a absolutely stupid price for the the thing. If you want to see large gains in breathing invest in a cam. As far as your question though, yes the Banks dual ram intake is capable of flowing more air than the stock one.

 

Yes, I will pile on to say all its worth is the paint and "neato" sticker you get with it. That goes for most of the intake elbows as if you really study the air system, the intake elbow is not the choke point. But its easy to see, easy to change and looks cool, hard to beat the "crow" factor...LOL...

 

We're getting closer , being that its Banks I exspected a high price [ but what are you guys seeing in price ] .
BC847 , any chance we could get better list of mods ? especaly since you have one [ although you oppted no name & red ] .
I'm at about the same HP & TQ , with very little power mods & slipping falling out of lock up trans. , witch is why I'm asking/panning ahead , I will be getting a moderate Goerand trans. soon , then I will feel free to add more power , but longevity & millage are my main consideration , until I fall in to a pile of $$$$ , I'm not holding my breath .
I was looking at the picture and thought that Banks should have a larger single leading to the twin , my idea being that the pluming should be bigger all the way from air/box/filter/cooler ect.
The cam issue is not in the future plans , so that may be an issue , weather to use this or not , but measured facts are what is needed to make these choises from my perspective .
Its like a mystery noval , when someone tells you some info leading to a answer & then leaves out the ###s , I'm cursed that way .
JUST THE FACTS MAAM !!!
Wait a sec. I still like a good story now & then .
Thanks John

 

I forgot , the freind in ? , said he liked a lot , added the Dual & #10 fuel plate at the same time , after thinking about that , it occured to me that almost all of what he liked was probubly the fuel plate .
But thats why I'm here , to shovel some out there & see if its ????
My freind is a full time RVer , & does not do the internet , he usally ask's me , but not in this case , he also does not follow what I come up with either , I told him that the 5" turbo back was over kill , funny thing is that we are all trying to help the other guy , but you can't make the horse drink the water .

 

John,

Keep in mind I'm running a VE IP.

My mods are

Air in ~ exhaust out:
- True 100% cold air filter housing w/BHAF https://www.dieseltruckresource.com/...31CABready.jpg
- Custom TAGIII
- PDR HX35 Hybrid turbo.
- 3" charge air plumbing
- Banks intercooler.
- Banks TwinRam intake manifold.
Stock engine long block
- ATS exhaust manifold.
- 14cm waste-gated exhaust housing w/manual boost controller set at 38psig.
- full 4" turbo back exhaust with high flow baffle type muffler followed by a 4" resonator (very quiet).

Fueling:
- OEM issue Bosch VE IP with 3200rpm governor spring, custom ground fuel cone, usual tweaks, timed at 2.0mm, main fuel screw run all the way in.
- PDR 190 injectors (approx 30HP over stock).
- CoolerMist Varicool W/M


Sucky "Slip-o-matic" stock A518 trans with full TransGo kit, dana70 rear w/3.5something gearing.

Stock, the CTD is rated at 160HP/400ftlb. Currently I'm a mild 243HP/522ftlbs on #2 all with very little smoke and EGTs of no higher than 1350*F. This was on a DynoJet 238 at http://www.fastlanemotorsports.us/ (72*F, 6%RH, Barro 29.71", Dew point 1*F), SAE corrected.


Red is #2
Blue is with W/M (still working on that).



I'm loosing a butt-load of power with the OEM torque converter, gonna upgrade that soon. A cam and O-ringed head will follow. Then a suitable bigger turbo and injectors.

All things considered, the TC and small injectors are killing me.

As far as your friends truck, I'd be interested in what his EGT's are with the latest mods. (Fuel + Air = power)

 

it's snake oil

 

I like your -102hp at 115 mpg.

Anyways. Got one on one of my 98's and doesnt really seem to make much difference over a stocker. Its a PITA to get off and on too...

 

LOL
Why do you beat around the bush Forrest?
Why not tell us what you really think

 

trust me, most people don't want to know what I really think... you gotta realize, as often as I get in trouble on this board, I'm only letting fly about 5% of my unfiltered thoughts


my momma always said "if you can't say something nice, don't say anything at all"

what she didn't tell me is "if you don't say anything at all, people will keep on spewing buffalo chips"

 

LOL Good point.
Funny how often those buffalo chips have red paint on them.
