Looks great. Can't wait until my 3.5" polished comes in next week.

And I can't wait for my chrome smoke candy red
This custom colors thing is the shiz.

[aldekei]

And my awesome chrome smoke candy blue... Is hidden by couplers.

The one piece set up looks great. I will be ordering shortly. Great product!!

Better order a 1-piece

[JDW1]

Got mine in yesterday. For the MS6 guys, I had to move my batt back ~1" or so, not too big a deal just drilling the new holes in the right place. also had to slightly sand the MAF housing to get the O ring sealed in there all the way. Over all it looks good in there and I'm looking forward to logging some gains once the map settles in.

[beachshoer]

This new intake with the dryflow filter sucks some serious air. After driving around a bit the sound is so much different then my old CS.

[Micha]

Can you hear it when you are driving?

I have mine waiting to go on when I do my turbo swap and I am hoping it does.

[JDW1]

You can, definitely and preliminary logs are showing 45 more g/s.

Damn, that's some serious air flow. What was your previous setup? And what size intake are you running now?

[JDW1]

The 3" with a BNR S3. Logged 375 and 390 g/s my first two logs. Tweaking it as we speak.

What boost is that at? The BNR generally doesn't go above 350g/s.

EDIT: If you're using a 3" MAF cal your MAF is overscaled. Take the 3" cal and multiply it by 0.87 for the HTP 2.8" MAF.

This brings you more in line with actual numbers which are ~335 g/s airflow which is what the turbo will flow at ~23psi at 60* F. You will also see that with an overscaled MAF you are running richer than your fueling targets.

I'm running 20psi and have AFR's ~11.8, maybe 11.6 by redline and it was 49* out. I scaled back your 3" sure on the other thread say ~.95 to get there. I was flowing over 340 with the cobb on there.

Ive never seen a BNR S3 flow a true 390 g/s let alone at 20psi and I've seen lots of them. Is this scaled for E85?

Nope, Chevron 93. Logs attached for proof. The 1st was before I scaled back to get AFR's in range, still may tweak them a bit. So you're saying I have a S4

[Lex]

I am saying something does not fall in line with every other S3 I've seen. Your turbo flows more than the GT/X turbos at that boost level.

Also coolant is a little low in terms of temperature ... but that's neither here nor there.

Then why don't I feel like I'm making GT/X power or am i at 20psi? Don't get me wrong I'm happy but I feel like theres so many guys out there making more.

also, whats the 165 coolant temp mean anyway?

When fully warm the coolant temp should be at or above 183*.

You're also right on the power, but your timing is very low and I still think that MAF is reading too high

[Dr. Speed]

Wasn't the BNR supposed to be "updated" sometime soon? @JDW1; maybe that's why yours flows better?... or have you had it for a while?)

And I suppose there would probably be more talk about it if it HAD already been updated...

[beachshoer]

Just got mine and installed my BNR S3 and as far as I know its no different then previous versions.

[JDW1]

I Like my AFR ~11.8, I could scale it back a hair more but i'm pretty close on that 2nd log.

I thought 10.5* was ok for 93. What do you think I can get to on 93?

I've had mine over a year, I wasn't aware of an updated version either.

[aldekei]

I think what Lex is getting at is that your calibration may be hiding a boost leak.

tapawhat

[JDW1]

Well I don't think thats it, I just instaled the HTP 1 piese with new couplers, checked all my EBCS lines and I'm running a top mount with upgraded boost tubes. On top of that my WGD tapers town as I maintain my 20psi.

[aldekei]

Same boat here, but in switching to a hybrid tune, I started hitting limits indicating a leak even though I held boost just fine.

It doesn't hurt to test.

If his AFRs match his targets then a boost leak is less likely but perhaps a very high content of ethanol in the fuel could be at play here.

Also in terms of timing you shouldn't be basing it on what people say - you should explore the maximum values for your vehicle. I'm willing to bet there's a good amount more left on the table in terms of timing even on 93.

All the pumps in Alabama say at least 10% e pretty much.

My full 3" intake in red wrinkle just arrived! Along with a delicious Cherry Tootsie Roll Pop that is already in my belly. It's one good looking piece and I can't wait to install it. Thanks Katie and everyone else at HTP!

[Lex]

@HTP;

Can you guys please post the inner diameter of your MAF housings for the 3" and 3.5" intakes?

I am getting a quite a few customers here that have issues with the MAF cals. From my calculations the ID of these intakes is somewhere around 2.75." The ID should be measured right where the MAF sensor sits, not where the pipe is bead rolled - so measure further in than the bead rolled section.

Also people that have these can you please measure the ID with some calipers? I want to settle this and get some MAF cals out for people to use and stop the confusion. A MAF cal for a 3" ID MAF won't work well at all for a 2.75" ID MAF.

Also when you powder coat these, do you powder coat the inside of the pipes as well?

[beachshoer]

I'll measure mine first thing in the morning. And as far as I remember there was no PC inside.

I just measured my 3" and it measured 2.801 before the honeycomb. I'm glad you brought this up, as I was just scaling my MAF for a 3" intake. I'll scale it for a 2.8" MAF housing and report back after I install the intake.

They don't powder coat the inside, but there is a small amount of overspray. I doubt it is enough to change the ID.

I can't wait to get this intake installed though, the build quality is top notch and the powder coating is flawless.

[Lex]

Alright, so I am noticing a trend with these intakes.

The MAF curves are not similar to other intakes. If you take a 3" MAF cal and scale it for 2.87" you end up with a 0.915 scaling factor.

However this factor is not enough for the higher flow regions (WOT). In some areas there it appears that the intake needs to be scaled 0.80. That honeycomb is taking up some of the pipe cross section but it is difficult to quantify.

With the gen1 cars it was easier to see if the MAF was off in the upper RPM since there were no WOT trims. With the gen2 it is a lot more difficult to do such a MAF cal due to the WOT trims.

A lot of people are reporting very rich conditions at WOT and skewing the curve in the upper regions this way indicates something is up. @HTP; have you one a complete MAF cal for your intake? I am starting to understand what is going on but if you had some data it would really help clear up some of the problems.

[rfinkle2]

@GODspeed7;, see Lex's post above.

God speed7 and I will have something for the 3" intake asap and will post it once it is dialed in.

@Lex; I am seeing the same thing. I was after Godspeed7 for a possible boost leak. LOL (sorry godspeed7)

Yup they all looked like boost leaks to me as well the MAF was so far off in the upper end. It is very strange to have to scale that curve in a piecewise manner; this shouldn't be the case because unless done on a bench it is hard to get it right on the car with such open breakpoints.

[Voltwings]

A little late to the G/S discussion, but at 25 psi on my 3071 i see 380 - 390 G/s... still waiting on @HTP; to release that 4" ...

Thats weird, I've seen 380 @20psi on my S3. How could that be?

[rfinkle2]

@Lex; do you have a first gen car you can run in full time closed loop?

Right now, I only have a gen2 and even though we would pick up some trim info and a basic curve shape, the owner will have to deal with some wacky ignition advance.

[Voltwings]

That i agree with Lex, something somewhere isnt right on your set up. Not saying its bad or wrong or dangerous you know, dont mean to cause any alarm, but something definetly seems off...

[aldekei]

Suspected boost leak... That sounds familiar, lol.
