by WOT maf cal, would that mean increasing the number of break points in the high flow regions and also up the close loop exit load ?

When you get a chance, check out pg. 49 of 86 of the atr help file. It provides a pretty detailed example of the exact situation.

Once you pass the value in the closed loop max load table in the logs, you would use the technique as outlined above to adjust open loop fueling.

Thanks. Totally forgot about this, last time I looked through this was when I knew absolutely nothing. :cool:
Will install and do some testing this weekend when I get time.

My HTP comes in tomorrow. It's too damn cold for me over here (I shouldn't complain, you guys in Canada sun bath in negative temps).

I am going to try to install it tomorrow and begin the tuning process. Unfortunately this issue is nothing new to me. My Cobb SRI never was accurate with the Cobb OTS curve. I had to add about about ~9% at WOT so even if there are some inconsistencies I have never minded tuning for it.

I'll let you guys know soon how it goes.

I had a small issue with the coolant hose below the TIP. I backed it out a little bit off it's connection so the intake would slide into the coupler a bit better. It was pretty damn cold here today. I'm thinking around 27-30 degrees. I did a lovely custom job of moving my ecu to the fuse box too. I'll take some pics tomorrow morning.

Interested in pics.

If you know how to calibrate the MAF no reason not to do the same here. Just be aware that you may have to calibrate at WOT as well as part throttle. You can scale your own or even start with the 3.5" I posted which will most likely run richer than commanded (safer if I were to choose one).

Installed my HTP 3" Today. Have the cut knuckles to prove it. Tight fit but kept the ecu in original location. At the advice of HTP i simply removed the ECU cover which gives an additional 3/8" clearance. So far so good. Justin is in the process of Freekin my tune now.

@Lex; Here is my current MAF Cal.

I just multiplied the whole curve by 1.22693 for now. I can't wait to get this intake installed though. :naughty: I'll post before/after logs either later tonight or tomorrow. The map won't be changing except for the MAF calibration.

I removed the cals from your post simply because they can get confusing for people searching for these. By all means try the cal, put some miles on it, and make the adjustments needed and repost when you've verified it and have a solid cal

No problem, I thought you wanted me to post it.

On another note, HOW THE FUCK DID YOU GUYS INSTALL THIS? No, but seriously I'm having problems getting the battery back in. Of course it's something stupid like that keeping me from putting it in.

I can't get the holes in the battery tray to line up with thw bolt holes and then when I did, there wasn't enough threads on the hold-down to get the nut threaded down far enough... What the fuck. Any tips for making this thing fit better?

Katie provided me with a PDF of the instruction manual via email and I believe I read something about drilling the battery bolt holes wider to be able to slide the tray over a bit and retain the use of the bolts.

I'll check

do what ms3blackmica said in the post above yours or move the ecu like I did to the top of the fuse box.

That's where the GA goes, lol.

tapawhat

I have an MS6, the ECU is in the cabin. I got it in finally though, and it just BARELY fits. I'm going to buy an HTP slim tray soon, because that was a huge PITA.

ANyways, the MAF Cal. seems to be pretty far off or maybe it's still just learning trims. I haven't driven it at all yet, but it's running kinda rough. There could be a leak too, I'm not 100% sure the clamps seated properly, so I'm going to do a boost leak test soon. I'll post some logs later.

You have no idea how long I spent trying to get both battery tray holes to line up... I ended up just leaving a bolt out. Lol. I never got the instructions in an e-mail, so I didn't see that tip. :grumpy:

Well closed loop AFRs are all over the place and LTFTs are very high at idle/low load. WOT AFRs are very close to my target of 11.4 and seem to pretty much hit it with no problem, but I haven't done a full WOT run yet. Another thing I noticed is that I'm able to hold my boost targets much better with this intake. With the stock intake, I could barely hit 16PSI and it would start tapering off to about 15PSI. Without changing the WGDC at all, I'm actually overshooting my peak boost target by about .5PSI, but holding it easily.

@Lex; @rfinkle2;

Edit: Closed loop AFRs calmed down quite a bit after some driving, but LTFTs were pretty high. +8-14% was the range I saw quite a bit of. I'm working on the MAF Cal. now, but I only got to 55G/s before it transitioned to OL. The MAF Curve doesn't seem to be very smooth after I made the necessary changes. I attached the MAF Cal. logs. There is a very small 3rd gear pull in datalog 6 as well.

That tray is one of those things that seems like a waste of money till you actually install it. At least to me it was. But holy shit does it give you room and make life easier. After putting it in I have about 2 1/2" between the intake and ECU. I run all my vac lines and occ hoses that way.

After attempting to install the stock battery/tray with this intake, I'd say anyone who is going to buy this intake should just get the tray... I ruined the finish on my intake because of clearance issues with the battery.

So I did a 4th gear pull and I lost power and torque... Lol. After looking at my map, it looks like the higher calc. load just put me into an area of the timing advance table that had very low timing advance. I'll have to adjust it to match the timing advance I was hitting before installing the intake. I attached the 4th gear pull log and a log from before I installed the intake running the same map. You can see I'm running almost no timing advance for most of the pull.

Here is a virtual dyno comparing the two logs I posted. The red line is with the HTP 3" and the blue line is with a stock intake:
http://farm9.staticflickr.com/8354/8...4923e68e_b.jpg
Please note that I did NOT lose power because of HTPs intake. There was almost no timing advance until 5,000RPM in this run.

I picked up about 30G/s of airflow over my last logs, which were actually on colder nights than tonight by about 10°f. I'm still hitting my commanded AFR +/-.2., so I don't think the MAF G/s reading is skewed by a bad calibration. My calc. load is higher by about .2, but that could just be from scaling the MAF.

When installing my 3" intake I had no problems getting the battery box to fit. I just made sure the coupler was all the way on the turbo, the pipe all the way in the coupler, and the bracket snugged against the engine. But I will double check to make sure it isn't rubbing.


Tapatalk LIKE A BOSS!

Boost_addict it's hard to believe you lost power.

Please only show results like that after you have completed your tuning with all things be as equal as possible.

Try the MAF Cal I posted in my thread on the Stratified section. Looking at your MAF scale it seemed over scaled in the top end.

I explained why though. I posted it thinking something was up, but then realized that the higher calc. loads put me in an area of the timing advance table that was running almost no timing advance. So, that's why I lost power. It had nothing to do with the intake.

I'll try that, but if it was overscaled, wouldn't I be running rich? I'm hitting my AFR targets almost dead on. I'll give your MAF cal. a shot anyways though.

Lookie what came in just now :D
Going to install after I finish my lunch :p

There has been alot of guys from the UK buying this intake also, certainly selling very well :)

So after the adjustments I made to my MAF cal last night based on the logs I posted, my LTFTs at low load are within +2/-2, so despite the MAF curve looking like there are some slight flat areas, it seems to be working well. I might still make a map with your MAF Cal. just to test it out for you.

I'm going to adjust my timing tables and hopefully post some legit comparison logs tonight.

Well I just got done taking the car for a spin after installing the HTP 3". I will admit it is a tight fit even with the ECU cover off but I kinda like it..Makes everything nice and snug.

First impressions: The engine is extremely responsive. Very snappy.

I scaled my curve by 1.14 and that got me within 7% on almost the entire curve. Datalog 3 is 3rd gear part throttle to almost redline. Datalog 4 is a quick 4th gear WOT in FTCL. I dropped boost and richened the AFR as I have some new plans to re-work this map with the new intake. I am extremely pleased so far.

I'm on my phone and can't read the logs. Care to give me a dummy rundown? G/s, AFR's at WOT, etc...


Tapatalk LIKE A BOSS!

Was running in FTCL so AFR's were spot on at 11.6. MAF g/s @ 5500 RPM was 325 g/s with the ECU removing 6.4% so estimating about 305 g/s. This was at 18.5 psi.

I am completely re-working this map so when I get some time to really tune it I will post some legitamite logs with things dialed in.

Just finished installing it. But looks good. Loading up a FTCL map and drive around to get the maf dialed in.

Good news, using Lex's calibration everything seems to be pretty spot on.
At WOT, AFRs are very close to my targeted 11.4. Only have about 10 miles of city driving on the map so LTFT's aren't accurate yet, but seem to be well within +/-8%.
I'm going to load up my map with normal boost and wastegate and let her rip!
I will most like need to tweak the wastegate and timing to get it as close to my pre HTP 3" runs to have as close of a comparison as possible.
I have attached a log if anyone is interested. If anything is out of the ordinary that I missed please let me know.

At first my AFRs while idling were into the 20's and the car was running like shit. I was about to flip a bitch thinking I have a leak on the intake, until I realised that i forgot to reconnect brake booster hose...

Thanks for the feedback. Looks like the MAF table I created is quite spot on - on a number of cars.

I will give the numbers a try when my I take comes in on Tuesday and report back.

I just loaded the map with your MAF cal. and its going well so far. Mine was off in a few places, but yours seems to be within +/-6% consistently. Thanks for posting it.

As a testament to @Lex; number, just ran 16 autox runs. Ended up me 5th and codriver/wife 6th out of 22 in our class. Not spectacular or our best. But the car ran fantastic with the 3" intake.

Here is a Vdyno after getting some timing advance in there.

http://farm9.staticflickr.com/8504/8...bc76ea31_c.jpg

Pretty decent gains considering I'm still running a little less timing advance than before. I'm using @Lex;'s MAF Cal. and I picked up 24G/s. There's a nice gain through out the whole power band too.

@ms3blackmica; @HTP;

The maf cal @Lex; made for the 3" was a great starting point for me. Only minimal adjustments to suit my car. The max airflow i've ever seen on my car has been 265 gs with the Corksport full intake. Now its the middle of summer here and yesterday I registered 280 gs in 90 degree heat. Looking forward to some cooler weather so I can do some 4th gear logs and get a new VD record for my car. Easy 300+

This is all so awesome! I won't be home til April but as soon as I am I'm getting my HTP 3" in and getting my Freektune on!
@boost_addict; That's some really good area gained under both curves! Post results again when you've got the tune fully dialed in. I'm really curious to see.

an initial wot run with similar timing on the 3" compared to the old setup on the cobb srt and tip showed about 5-10hp and tq less,
but that is with 25-30 degrees higher bats and humidity in the 90's. According to the logs I've picked up around 20g/s of flow.
Going to run this map a bit longer and get another log with similar weather condition to the log with the cobb intake, and also
allow the maf cal to settle so I can fully dial in the maf.

Here is a before and after for my car running my most aggressive map. Only difference between tunes is 1 psi xtra boost.
Got me over 300hp woo hoo
http://i1017.photobucket.com/albums/...psa0a63ed9.jpg

Just received my polished 3.5". Looks amazing, hopefully I can get it installed in a couple of days when I have a slow moment.

I can't wait until April when I can install mine! Candy Red with Chrome Smoke base :D
Absolutely beautiful and I'm sure it'll look even better in person. Thanks HTP! (and Katie)

I'm 2 revisions in (1 being the starter map) and this intake is just about tuned for. I'll grab one more log and its a wrap.

Easiest intake I have ever calibrated.

What MAF cal did you start with?

I took my Cobb SRI curve and scaled by 14%. When I measured the Cobb vs HTP inner diameters it was 14% larger area.

I forgot to mention BTW, if anyone has a VTCS delete they will need to massage the idle region and up to ~18 g/s region. Deleting the VTCS (like I have) causes trims at idle and throttle under ~18 g/s to become very positive (in the area of +15 to +19). This is not soley for the HTP but any intake.

14% larger area or diameter? diameter squared (area) should be used for scaling.

Glad you got it working quickly.

14% larger area.

I made a typo and didn't ninja edit it in time for you to see lol

I'll post some logs when it is all done. I have a 6th gear cruising on highway log but no WOT since it has been raining

Posted a 3.5" HTP beta cal in the Stratified section if you guys want to give it a try and get some feedback on it. It is based on their 3"

Ordered a 3" in a single stage gold! Can't wait to see how it turns out.

Just received my 3.5" today! Thanks for the quick delivery and tootsie roll pops!

I just got the email mine shipped today. Now I need to go over the MAF cal modifications in ATR. Thanks to all that have contributed with MAF calc tables and how to's.

Anyone have any pics of the 3'' intake installed? Been looking around but I have only seen the 3'' TIP and 3'' MAF but not the full 3'' intake, just wanted to get an idea of spacing is like.

There IS no spacing. Honestly to go with a 3inch or bigger you need to do something with the batt tray. We put two on at the same time but a batt tray with mine and it's night and day. The other guy ended up buying a tray two days later.

I do have a picture up of mine with the tray. Its either here or in the 400 hp BNR thread.

Ask and ye shall receive. ECU ghetto located because BNR soon and I'm working on a small battery tray of my own doing. Now if you'll excuse me, the coffee enema is kicking in.

Here is mine with a 3.5" intake. ...I am ordering the battery tray ASAP haha. You can manage but the tray is going to be well worth it.

Thanks guys, I was thinking about getting the 3'' for the summer and get a tune at the same time. Just wanted to see the clearance with the ECU in or relocated. When I had my JBR it was rubbing everywhere and everything that it could get close to without the slim tray. I just wanted something to fit without deforming anything and I don't mind relocating the ECU for the extra space.

You need to post a pic with the battery tray installed....

I got mine to fit doing my own batt tray relocation, just had to move it ~1" back. It's snug but you can do it with out buying a tray.

Another horrible night shot but here is the battery tray added. Just for kicks here is the photo with the ECU relocated. Ill try to get day shots later.

Ok here are a couple of day shots of HTP intake and battery tray in polished finish.

I got my 3" intake installed today. I used Stratified maf table in my pretty much stock ots stage 1 93 map. Here are a couple of logs with only about 10 miles on it. 4th gear logs. Thanks @Lex for MAF table.


Two more logs. I used them for maf cal. Now ltft's are from -1.6 to 3 logs 4 & 5 used for maf calcs.

For those who've been waiting, release information for our 4.0" intakes is posted up here!

Any love for the speed6?

@HTP;

The 3" intake is compatibable with both the 3 and the 6, what about the new 4"?

Can the 6 owners purchase the same 4" or do they need slightly different dimensions?

In order to use a bigger intake on the 6, you will need either a smaller battery or a battery relocation. I just installed the 3" and it fit with a few changes. I had to slide the battery back but that may be due to the duralast battery that's longer than stock

I had the same problem. I could force it to fit, but it rubbed off a bunch of the powdercoating. Here is my 3" with the stock battery:

There is TONS of room with the group 51R battery tray from HTP though. I highly recommend picking up the 51R tray if you're installing one of these. Here is a picture with the HTP 51R tray:

I got a hopefully quick question on installing my 3.5" HTP intake on my MS6:

Installing large intake - MS6 - Mazdaspeed Forums

Sorry if this has been addressed but do you offer the 3.5" without the recirculation tube?

We certainly do! And it'll actually save ya about $10.00 too. Shoot me a pm or e-mail if you're interested.

I have had my gold 3" for about 2 weeks now but just got the opportunity to photograph it.
Here she is:

I have to say that Katie was more than helpful in ordering this and I most likely will be doing business with HTP again.

Copied from "4 Inches of HTP Intake Goodness Coming Your Way":



It's March 1st and that means our 4" intakes are now available here for the Mazdaspeed3!

Also check out the combo kits with the 51R Small Battery Tray:
HTP 4.0" Intake System + 51R Battery Tray Combo Kit (MS3) - Hi-Tuned Performance Products

We're running introductory discounted pricing on both the intake and combo kits now through March 31st, check it out!

For you Speed6 guys who have asked about fitment, we have a car scheduled for test fitting next week so once that comes in we'll have a definitive answer for you. Thanks for your patience!

Anyone with a Speed 6 have to notch the battery tray to get it to fit? (on a K04)

Mine just didn't want to cooperate without modifying the tray.

http://img.tapatalk.com/d/13/03/02/zabuhyse.jpg

I believe the MS6 that we used to test fit had a replacement battery that was a bit smaller and that's what may have thrown our measurements off. We will be verifying everything next week and coming up with a solution.

Matt

Oh I want to post up a pic too! Tray and 3.5" install was a breeze! Thank You @HTP;

Great stuff, it would be nice to know, the actual tray had to be modified slightly too, it was rubbing the pipe, I must have installed and removed the intake several times to see if I got an improvement.

Thanks Katie at @HTP; for everything and the suckers.

Anyone install the 3.5 on an ms6 with cp-e fmic? I'm concerned there is not enough room since the hot pipe on the fmic goes down the driver side.
@HTP;

YOU ARE WHAT YOU EAT.

I had to with the BNR, no way it was fitting. Easy to do though and turned out fine.

Well, that is what I'm going to be doing. I have to get a custom unit due to my stupid Steed Speed manifold. But, based on preliminary looks using the one I got at first, I believe it will fit. I will be getting the unit in soon.

EDIT: See the picture above, the hole to the wheelwell is clear.

Anyone else have a problem with the aem filter slipping off?

I am not having any trouble. Using the supplied clamp my filter is not going anywhere.

Ether the clamp slips off or filter will slip off. I feel if the bead roll on that part of the intake wasn't there then I wouldn't have a problem.

No issues at all.

tappy-tap-tappytalk

The bead roll is there to prevent slipping

Sent from GalaxyS3

I know but for me it's causing the slippage.

Hmmmm, @HTP; any ideas? Also try posting a vid of the filter slipping off and call them.

Sent from GalaxyS3

I'll do that. If aem added an additional 1/2" to their coupler it would also be fine. I'm going to try some sandpaper to scuff it up.

Updates?

Now, to be clear, I'm not running the HTP intake, but I do run the AEM on my Cobb intake which has just a lip about 0.75" deep to attach the filter with, no bead or anything.

Since the HTP has a bead, and there's no air pressure or anything pushing against it, what's causing it to come off?

Seems like (guessing here!) it would have to be not on far enough to have the bead on the other side of the clamp, or it's vibrating so bad that the filter is being shaken off. Or both...

I dunno. I know you know how to turn a wrench Boosten!! Curious to see what's decided

It doesn't go on far enough cause the lip you said ^^^ the clamp slips off the filter if I clamp it where it should be or if I clamp it on the other side the whole filter slips off. If I clamp it on the bead then the vibes makes it come loose.

Maybe heating it up to get it a little tacky?

My friend suggested I try degreaser to take the oil film off.

I'm using my pepboys special for now till I figure something out.

IMO a bead roll is not needed on an intake at least for the filter side as air is being sucked in. No boost is going threw it.

The turbo side yes cuz there is no support braket for the intake.

Don't get me wrong I love the intake but the stupid filter. Lol

What size do you have? The filter on my 3" isn't going anywhere.

3.5"

filter on my 3" hasn't moved an inch since installing it about a month ago

I would try and wipe off that oil residue that is on the AEM filter. I don't like how they have the residue on there, but that's how they are shipped from AEM. Clean it off with some brake/parts cleaner, let dry, then make sure the filter is pushed on all the way.

We are still trying to make schedules work to get a local MS6 in here. Not a whole lot of them in the area, but it should be this week.

We put the bead there for long term functionality. Over time the rubber on the filter gets hard and the filter will wanna work its way off. We have seen this happen many times over the years so we would rather be proactive than reactive.
