I can't believe you let him just insult your weight like that...

The concept some people don't understand is when you have a compressor inlet that is 2.43, a intake/inlet that is 3", 3.5", etc. will not net anymore flow. There is still a bottleneck. Not taking into account flow capacity of turbo.

[Todd98SE]

Not necessarily, a 2871 compressor is the same size whether it is paired with a BNR 2.25 inlet or a GT 4" inlet. Both neck down to the same size they just do it differently.

[Etipp98]

Hmm then how are people going from your standard Inlet pipe to a 3" setup are gaining 10-15 g/s? You are relieving suction static a bit by a larger area. I agree that you can only gain so much but there is some to be had for sure.

The less resistant flow you have before the turbo inlet, the more efficiently the turbo can work.
It's why the evo and Honda guys put the inlet facing forward in the front bumper with no intake at all.

Can you show me a pic or diagram of the base of a compressor housing inlet being larger than the compressor inducer diameter? All I'm saying is the compressor wheel inducer diameter still determines the max width of the compressor inlet where they meet. Please point me to some documentation if I'm completely off base here.

The larger intake tube minimizes pumping losses and increases compressor efficiency. Fit the biggest tube possible that will allow the MAF to still function properly realizing you will reach a point of diminishing returns the larger you go.

Well, keep in mind turbulance as well. If you are injesting 4" worth of air at the MAF, its going to hit a wall at the 2" inlet to the turbo and back up into the intake giving your MAF screwy readings. like you said, fit the largest that is "optimized" but figured id qoute what you said anyways and add : Just because that air is sitting in the intake does not mean the system is optimized.

What? The MAF is only ingesting as much air as what is being pulled through it. Air doesn't backup in the intake tube and cause MAF problems. The MAF problems are caused by lower gas column velocity due to the diameter increase, hence the increased importance of the airfoil/straightener. Remember a 4" inlet GT2871 still necks down the same diameter as the 2.25 inlet BNR at the inducer.

[Ziggo]

We are eating around the edge of the pie here. The reason for the performance benefits is the higher pressure at the turbo inlet, which reduces the pressure ratio of the turbo. Reduced pressure ratio (usually) means reduced BATs (increased flow) and less backpressure in the exhaust manifold, which reduces the amount of work lost during the exhaust stroke (increased thermal efficiency) and less residual exhaust in the cylinder (increased flow)

Inlet pressure has a large effect on the pressure ratio because it is the divisor, raising it decreases the pressure ratio quickly.

I brain farted, I was applying the blow through logic from my set up, Not draw through.

This is not a fukin honda, no relation. failed to proved point Tokay444


Show me a log proving the increased flow on a k04

[CamSpeed360]

I think we are forgetting that this behemoth intake is not for your k04.

Well no its not a Honda but it is Turbocharged and the principle is the same. Less restriction = more airflow. Where it is not relevant however is that most Drag Hondas and such are running turbos much larger than the K04. Hell switching from 3" to 4" on my 3071 i noticed a huge difference, it fucking LOVED it. Now imagine the size turbo a drag car is running... think dudes gonna be rocking a 6"+ intake? Probably not, thats why they just run it open element like that.

[burn813]

Man, this thing looks even better in person! Compared to my current 3.5 inch whale penis I believe the fitment is even better. The design is very well done. I do believe that I will be purchasing one of these in the very near future.... Actually I wanna call dibs right now!! Lol... I would love to talk about the other things that are in the works but I signed a non-disclosure agreement with Matt and I sealed it with my semen.... Sooo

exentix, you got any logs pre, and post wide path for this fool?
I couldn't find the quote where you said that it made the biggest difference of all your mods.

[exentix]

I'll try to find the ones I got right before it with a full stock sized sure intake, and after the maf was calibrated. Without throwing out any figures, I went from squealing second at best to straight spinning second. Nothing else done, I noticed a bigger difference stepping up maf size than when I threw my ap on the first time, or even from a downpipe. And I noticed NO difference when I added a stock sized intake to an accessport only car.
Tokay444 ill post logs later today

I can tell you for a fact that my k04 was only pulling 280m/s tops with a 3" maf coupled with a sure sidewinder. Now I have the htp 3" inlet/amsoil filter so a full 3" intake and my car is pulling 310m/s.

[Easter Bunny]

@get in here with some links

Edit: stupid iPhone someone mention dale gribble. He has been running a lot of intake sizing tests

EDIT #2 from a computer - @

Pressure ratio is pressed ratio is pressure ratio.
Matters not what platform the turbo is on.

I need one of these bad boys!

"Sorry just trying to post enough to be able to PM someone to get a tune lol"

[forcedinduktion]

Mine was at 273 with stock TIP and went to a peak of 283 with HTP 2.5. Beyond that it won't flow anymore. That is neglibale at best. Groan these nuts faggot

Not my intention to disprove the filter element's effectiveness, but do you feel some of the increase in g/s could be due to weather changes (i.e. colder weather now vs. older logs)?

30 g/s is a BIG difference in flow.

Ok what supporting mods do you have. Catted DP or catless? 93 octane or e85? Stock manifold or tubular manifold? There are SEVERAL mods that will effect g/s so just because you did not see a gain doesnt mean there isnt one. The intake is just one piece of the puzzle. 2.5" is enough for a 93 octane speed, but on E85 they love the 3+". 4" may be arguably "too big" but the point is there is a gain, even a marginal one.

Not really, temperatures were about the same, logs were just done a couple days apart. I never even saw 285m/s till I dropped in this htp 3" and amsoil filter.

You are a lucky man. I have the 3" HTP inlet and a large filter and definitely did not pick up 30 g/s.

well looks like i dont have any logs left from my old intake, i got rid of them. however, Lex commented on my logs when we started my tune. he said he was surprised to see how much air i was flowing with the larger maf and catted dp. imo, its well worth the money.

[h.h.sk1nny]

My car was always low on m/s...normally I was 260-270 all while fully bolted. I am def hitting 300+ now lol. What filter are you running? Before I was on a atp filter, now amsoil 9" long 6" diam.

It is a big K&N, 7 inches long and 6" diameter.

This was on 85....ugh manifold? That would defeat the whole purpose of this comparison. We are comparing size of inlets not max possible flow

[Lex]

When you pull air through a pipe you lower the pressure from one end to the other. The pressure drop is determined by the diameter of the pipe as well as its length. So a 2.5" inch diameter pipe that is 1" long will cause less pressure drop than the same diameter pipe that is 1 foot long.

Why does this matter? Because want as much pressure at the compressor inlet as possible.

On the K04 a 3" turbo to filter intake is worth about 10-15whp worth of flow versus a conventional SRI.
