Blow through MAF

[MSP #167]

i want to do this but i don't know where to take my pipe to get fabbed up.

Do it yourself

i want to do this but i don't know where to take my pipe to get fabbed up.

This is a pretty easy DIY. All you do is get a hack saw or a dremel and cut a section out of your pipe that is about 1/4 inch longer than the MAF. Then you get two reducers which are 2.75 - [insert yopur pipe size here]. Pop it in and you are done.

Really... there is nothing to it.

use a sawsall...

what kind of reducers? Like rubber ones?

SKU#T2234 2"ID to 2 3/4"ID x 3"L (assuming you are using 2" pipes)

k thanks maybe i will do this then when i get some time.

I'd like to see an FMIC/hardpipe kit that has this option. Hint hint, vendors

I put my maf on the pressure side as well and I couldn't be any happier. I don't care if it does take some of the life off the sensor, the difference in how my car is running now makes it worth every bit of it.
Has anyone dynoed their msp with the maf on the intake side, then moved the maf to the pressure side and dynoed it with the same setup?

Where do you place the air temp sensor? on the pressure side as well, or do you leave it pre-turbo?

 

[ZenProtege]

I put it in the air filter, I drilled a small hole in the rubber at the base of the air filter and wedged it in there

Ok. This sounds really easy, but I'm having some sort of brainfart here. Can someone post a pic of the stock setup and draw in lines as to where to cut/move? For some reason I'm thinking that there will be a gap left in the pipe.

I don't think it would work very well with the stock plastic pipe.

 

[ZenProtege]

I agree, I wouldn't cut the stock piping just to move the maf, it doesn't seem like a silicone coupler wouldn't hold well to the plastic, especially with all the weird oval shaped bends

 

[wicked]

no on the stock piping,I'd only do it on hardpipes,or a FMIC hardpipes.

 

[Metal MP5]

i will def do this within a week or two

Putting it on the pressure side would be a nightmare. I could easily see it popping out. Just put it in the intake. I am too lazy and I zip tied it to the outside of the filter because the wires wouldn't reach for some reason.

Hard pipe

Definately need a hard pipe. They are not expensive and besides, the car runs sooo much better with hardpipes vs. the plastic. No boost drop.

EDIT: Theoretically it can be done. You can go to AutoZone and buy 2 stainless steel 2" to 2.75" reducers and insulate the 2" side with a rubber strip and jam the 2" side into the plastic pipe. Then use clamps and couplers to seal the deal. But quite frankly it would be silly.

i was looking at my engine bay last night thinking about this ... i have a question. I bought a set of extra injectors with my MPI tuner that goes on the IC>TB pipe. How's that gona affect the MAF if i relocate it on that same pipe ? I read about air coming back through the MAF when the TB closes, what about fuel coming from those injectors ? any chance of that going back through the MAF as well or it'll be out of the way before the TB closes ?

the injectors are not installed yet, but will be soon. I was going to try to have those welded as close to the TB as possible, then try to fit the MAF between the injectors and the BOV

any specific distance i should keep between the tb > injectors > maf > bov ?

Do you already have the BOV on the pipe? I have mine coming off the turbo to intercooler pipe. It works great there, and would give you extra room on the other pipe to space the MAF from the injectors.
