I agree it is a good way to grab more of the market, however if I remember correctly the stock maf sensor can only read enough air for 400-450 HP, more then enough for 95% of the market but as you know they are pushing the limits beyond that. Now if you steo up to a 3.75" intake or a 4" intake you can go even farther. There are some other thing esmeril does that wont work with the stock ecu. But it looks like they may consider making a blow through kit, which sound liek a good idea to me.
Mazsport did not make the int-x, they just supported it.

people do run more boost with ethanol, but that is because of the higher octane rating and that translates to more power, granted there are probably even less people doing this than the 5% mentioned above...
but to make the same power, your air flow should be higher.. right?

We actually have that in our list of short term development.
We have discussed this internally several times....the most viable option involves having a "Cobb upgrade kit" that includes larger 3.5" MAF pipe with the MAF running blow through like it is done in many other turbo applications. There will have to be some kind of air "straightening" device in the pipe to aide metering. I am unsure of how much hp will be reachable before maxing out the sensor in blow through form but this appears to be the only way for our kit to work due to our intake setup.
Any suggestions???

Someone with an Esmeril kit needs to setup up and do it! The BOV pipe needs to be changed, the whole top pipe needs to be 3.5" diameter.
Here's the MAF flange: http://www.kstech.biz/servlet/the-2/...ugh-MAF/Detail
Our MAF is a Denso element used in STi's and they run blow-thru all the time. It works. Someone just needs to do it. I would do it on my setup but obviously I can't fit a 3.5" 6" long straight pipe before the throttle body without serious re-working of the charge piping.
But if I ever build that custom kit I've been mulling around it will be blow-thru

There's a guy who lives near me (on the forums: Migi'sBatmobile) who instralled the esmiril kit over a year ago. I dont talk to him too often but he had huge problems with his IntX and decided to get a Cobb and had a custom pipe made to house the MAF. I dont know about the positioning but I believe it would be a "blow through setup". I havnt spoken to him in a while but I believe he didn't get it to work, but I dont know why, he could never get the car running from day 1, he's not the most proactive guy in the world but I think he's been making steady progress. Last time I talked to him he was going back and forth with MM about a tune for it....
Anyway, my point is he is already well down the road of trying this. I'll try to call him tomorrow and see where he's at

Yes. Contact your friends at BHR and we will be happy to help. Simple as that, Chris.
Matter of fact, I have already discussed such a set-up with MazdaManiac and the h.p. "limits" whether blow-through or draw-through are the same. Remember, the MAF measures air mass. As such, it does half the job of a carburetor.

P.S. Esmeril Kit no longer uses these things, in fact hasn't now for over a year.
P.P.S. Anyone buying a Turbo Kit that doesn't realize that they can change the Turbo and Wastegate have no business having any of the three.

I could be wrong, but I don't really care.
Way to come off like an ******* btw.
P.S. Like I care if someone with an esmeril kit or any kit for that matter makes more power than me. My estimate would be somewhere between 315-325 RWHP for my setup atm. Just sayin'.
P.P.S I make more power than you so you probably shouldn't be saying anything. Kthxbye.

There are ways to make the pipe appear "bigger" to the MAF without actually making it so. There are even ways to make it appear bigger the more flow that goes through it while maintaining very close to stock idle readings. I am working on a design to channel and control the amount of air the MAF sees while sticking to a 3" pipe. This will take some time but I will keep you updated.
Best regards,
Chris

There have been "fooler" pipes doen for MAF setups in the past.
It can be done, but its not really necessary.
The current MAF setup is good to about 490g/sec if you scale it all the way out to 5 volts (Mazda stops short by about a 1/3 of a volt).
The pipe can be taken up to 3.5" i.d. without killing the granularity too badly, giving up to 550g/sec or so.
I just don't see too many people going for that kind of flow on these motors with the OE PCM.
I could be wrong. (Because of tuning skill, not mechanical limitations.)
