blinx's official intake thread: which intake really is the best? i answer it.


The intake on that particular setup is actually one from an ITR.

Regarding the cost factor, since we're talking about custom intake manifolds, the one from Endyn is $945.00 so the whole issue with ITBs costing considerably more is moot.

Of course if we're comparing it to an AEBS or Skunk2 or even a Performer X, the cost factor can be considered.

From a cost vs. performance ratio, the Performer X, with a tapered - bore throttle body, Intake insulator gaskets (outlaw engineering) with a tuned length intake pipe + velocity stack and a large diameter cone will make 95% of those frequenting this board extremely happy already.

The Endyn custom manifolds IMO, are reserved for those who have the built to the teeth motors - the type ready for ITBs per se.
 
hmmm, I thought ITB injection kits were around $4000 + plenum

Toda is about that.

well said on both points, anything past that is opinion or preference :nice: the itb vs plenum debate is like the turbo vs supercharger or turbo vs NA, at the end of the day its what makes the end user the happiest, there is no right or wrong answer imo as long as the car moves the way you want it to :drive:

Hardly...it's more like $2700.00 and that's retail. They can usually be had for a couple of hundred less.

Still, there are other alternatives such as TWM, Jenvey and Kinsler to name a few. JDM flavors include Toda of course, OER with offerings from Spoon, J's, and M&M being all quite similar. Prices do vary and can probably cost up to $4000.00 with options like magnesium manifold castings but can be as "affordable" as $1500.00 to start.

Thats a interesting champagne rocker cover, looks good!
 
I'll add to the intakes and I am sure not many of you get a chance to see this setup

I also have a mugen and feel's setup
 
I've seen this one... Similar to stock intake, sucks air inside engine bay under the cover
 
dont think so the price is part of the reason I assume $1200 average
 
This one makes the same loop as the stock intake and then comes up into the corner where the stock one is. Cover goes on top of the pipe duct, just like the stock intake.

holly **** does that come with a hand job? thats unbelieveable, and i thought the mugen was expensive... is there any justification for the price?
 
Pretty good performance largely because it is based on the ITR's 3.0in diameter intake but will fit into swapped hatches.
 
If anyone is interested, I have the calculations for inlet tract length and port sizes and likewise for exhaust headers.

What do you guys think of the AEM V2?
 
I remember Tbone from honda tech and his B series all motor project that aimed 300 WHP. He did not succeed, I thing he made 270 WHP but concerning the intake I remember answer he gave me:

"i think we can find more power in just a few modifications.. Intake tube length and diameter being the first. i gained 15 whp just by tuning the lennth of mine and going up to a 3.5 inch pipe over the standard 3 inch. i found the longer the better too."

So he had bored block to 85 mm and all the stuff possible except ITB. He made series of dyno test with different length and sizes of tube until he found measure that gives most power to his configuration.

This is why I decided to make new intake with limited budget. There is guy from ORG-racing.com that sent me 70 mm 76 mm, straight and 45 degrees pipes and hoses, and Blox velocity stack from Blix, so I am going to run tests on my b16b to see what measure will be the most. 200 $ all this stuff with shipment to Bosnia.

Mathematically speaking,there is Helmholtz Resonator Calculations formula and Variable length runners formulas and lots of inertia formula to do this complicated calculations. You can find this stuff on team-integra.net. You will see runner length are something like vtec cams. they change length to give performance. :)

Engine try to pull air in the small RPM, after Air get speed and inertia it flows to engine, it hits the closed cylinders on one side and passes to open one pushing exhaust gas out. If hit the closed cylinder it creates wave back making resonance effect. ITBs seems not to have this effect noticeable..

"Notice that with invididual throttle bodies (ITB's) you lose this resonance effect because the reflected wave escapes out into the engine bay (or the atmosphere) and is not stored and returned by a plenum/acoustic chamber."

:) I can **** a lot :)

i think ITB's still have that affect, is that not why TWM itb's can be extended to be longer? I could be wrong here i had a good bit to drink this evening :D

the tip of the J's intake where the filter fits onto is 4in wide :D

Idealy the intake pipes should be bigger than your exhuast diameter pipes to reduce air drag :nice: your correct!

actually intake pipes wouldnt make a difference if your throttle plate is smaller than your intake pipe. getting a whale's ***** won't do anything, because by timeit reachs up to the throttle plate it will be back to a stock size which is smaller.

that's my two cents i got from school at least.
 
I think velocity still plays a roll, if the larger pipe can somehow speed up the air then it should still make power despite using an OEM throttle body, such is the theory on using a taper bore throttle body. :nice:
