Txakura Posted March 27, 2010 Share Posted March 27, 2010 During some serious reading and searching I saw the idea of the MAF mounted after an IC, this made some sense to me, but I didn't see anyone that had done it. It wasn't the direct target of my searching, but a side note. Has anyone done it? Is there any advantage or disadvantage to it?

The Beast I Drive Posted March 27, 2010 Share Posted March 27, 2010 Im pretty sure the stock EA82 MAF does not work correctly if it has boost through it, but I could be wrong. Note how the stock MAF is located before the turbo on the stock setup.... -Bill Quote Link to comment Share on other sites More sharing options...
turbo5speedgl Posted March 27, 2010 Share Posted March 27, 2010 some one has done it on here cant find it tho. they said it helps with the bov to atmosphere cuz it wont bring air through the maf as its after the ic other wise it will run rich everytime you shift. you can run the maf before the ic and and just use a recirc bov back through the turbo intake .

simple monkey Posted March 27, 2010 Share Posted March 27, 2010 this is a common thing to do when using either a blow off valve or a front mount intercooler. there is a post in the new USRM section about this. http://www.ultimatesubaru.org/forum/showthread.php?t=64741 i tried this on my subie, but the turbo exploded and a valve got broken before i got to drive it. having the MAF after the BOV allows you to vent it to the atmosphere since no additional air is passing thru the MAF. it wouldn't hurt to try. if you do, post pictures, then document it; a concrete answer on this topic is yet to be proven. on 02+ wrxes, this seems to work well.

(stock ea82T, no mods planned beyond IC) Pls, keep me in the loop on this one. I am planning on doing the same thing to my GL10. I just got an '02 stock WRX TMIC off CL today for $15... Of course my water pump went out on Thursday so I am spending this weekend replacing the water pump, timing belts and all the seals on the front of the motor so it might be awhile before I get to it. This is my first go round with timing belts so we will see if I get it done before monday... Quote Link to comment Share on other sites More sharing options...
Numbchux Posted March 27, 2010 Share Posted March 27, 2010 running blow-through MAF is pretty common. BUT, you have to be able to manually adjust your fuel trims. as the higher-pressure air will effect the sensor differently. It does mean that you can push more cfm through it before maxing out the sensor (another reason for doing it), but you have to be able to tune the ECU to compensate....

Txakura Posted March 28, 2010 Author Share Posted March 28, 2010 hmmmmm... much to consider, perhaps get the IC going before I get cocky Quote Link to comment Share on other sites More sharing options...
