The pressure side, after the BOV. But the mitsu maf seems to be alot more more forgiving than a vw/audi maf.

 

Good call. Lets keep it scientific and try to be as methodical as possible.

 

Ill swap it back and reset the ecu before i take off today.

 

how did you move it to the pressure side. my maf had enough trouble reading the incoming i doubt it would have kept up with the pressurized side. i burned out 9 mafs

 

We are talking about the Mitsu's right? My lancer's maf work well on the presure side, i wouldnt ever think about running a vw/audi maf on the pressure side (a handful ran it, for year+ before i left the mitsu world). Just remember 6psi from a gt28r is far lesscfm and pressure than a 16g.

 

oic i thought you were talking audi. my bad. ya 6psi isnt bda. i could not do that at 23psi on my turbo

 

ive found only 1 BOV to work and not cause any trouble with my 1.8T motor on my A4, and thats the HKS SSQV bov. so far everyone here has tried tellin me that itll mess up my engine make the engine not last as long and so on. it doesnt leak, the bov is designed so its impossible to leak under any boost pressure, its not spring loaded so the springs dont wear out or u hafto try n try again till the spring u try works. My SSQV works, has been working for as long as ive been using it, not 1 problem yet, and im pleased with it, ive gotten it from an Audi/VW shop, one of the best in thw world, and thats all they recommend for the 1.8T engines, given even some 1.8's might not except this BOV, but thats far and few theyve found

 

and also u need certain parts to block off the old setup

 

cool glad it worked for you. however i have herd horrible things about that bov but to each his own. im excited to test this forge out. damn ups hurry up

 

so how are you going to run it on an evo that takes 34m inlet and outlets?
