MAF relocated

well, the only disadvantage would be cutting the diameter of the pipe w/ your tool....it can only cut so much....

you talking to me?

I use this all the time on intercooler pipe,look in my sig,I built the intercooler piping,and the intercooler.

I use a dremel on high speed with a diamond cutter blade.

This thread might be dead but thought this might be good info. Last night I did my cheap mods install.

1. Replaced PCV valve with Mellinia PCV, part # JE26-13-890, $13.50 from Mazda
2. Removed Diffuser form MAF.
3. Moved MAF to TB side
4. Now running open BOV, No more Turkey just WOOOSHHH
This Morning was the first drive and Holy Crap! Its not in my head, this car is faster. Not sure why though. Throttle response is better and power is better from about 2300 on up. Just drives 100% different. I will try and get pics soon of the move. Looks good. The whole project probably took 15 min.
Easy mod.

what diffuser did you move?

Didn't move it just REMOVED it. (thumb) The one in the MAF

When you say you are runnig the BOV open vent are u stil using a BPV?

No, Its just venting to open air. Is that bad?

thats what im running

 

[Blitzd]

thats what im running

Its odd that it Wooshes and Turkeys, but just a little bit of the Turkey.

Subbing for later use.

well...........mine wistles. but i ONLY get turkey if i shift without going into boost while revving a lil high. otherwise i NEVER get turkey. im running on a hiboost fmic at 8lbs with a greddy type-s bov and a injen cai converted to short ram

I have just last night done the mod so I am still feeling it out. I have a Hiboost FMIC and did the CAI convert also. (worried about the water) But I swear I have more low end torque with the Short ram.

well your getting the air quicker

i'm kinda new to all this, and have some questions

what does replacing the pcv do?
What diffuser?
What do you mean "open bov"

 

[Velocifero]

1. replacing the pcv is just a maintence thing, not sure if the one that he listed is better or what, I am guessing it is less prone to gumming up or something?
2. inside your mass air flow sensor (MAF) has a waffle like pattern diffuser inside it, he removed it, creates less turbulence and unrestricts a small amount of flow, that air is gonna get rushed through the turbo anyways
3. open BOV means his Blow Off Valve (BOV) is vented to the atmosphere under the hood, it doesnt recirculate the air into the intake like the stock By Pass Valve (BPV) does

I call bulls***! cuz i did it today with that exact sawsall on my hiboost kit. my mom was passing by and i asked her to hold the pipe down so it didn't fly everywhere. i told her a guy on here said it would only take 2.6 seconds. about 20 seconds of my mom's arms about to fall off she goes "i think that guy was full of s***".

(first)

has anyone done this with a wideband installed and monitored the AF? I'm interested to hear the results. The reason I"ve been hesitating from doing this mod is that the MAF, as I undertand it, measures airflow at ATMOSHPERIC pressure. The hot pipe is pressurized so wouldn't the MAF readings be off? Also, that little dangly thing looks pretty light weight inside the MAF, I can't believe no one has had problems with it breaking.

 

[peepsalot]

I have a wideband, and I was still plenty rich after doing this mod. The dangly thing is delicate, but pressure comes from all sides, so the forces balance out. It's not really putting stress on it the same way as poking it with your finger would.

 

[tiwing]

OK cool. how far from the TB does it have to be to minimize the reverse pressure wave hitting it from the TB slamming shut on gear change or rapid deceleration?
