MAF Question

Gravy · 02-06-2008

Quick background on the car before i get into the question.

91 Dodge Stealth RT, TT with 14b/16g turbo going in over the winter. Car will be logged, SAFC-II, Wideband, and 550cc injectors or 450 depending on my needs.

Now the question is, i'll be putting in close proximity to one another, the MAF and the BOV. Is there any recommended order for putting these two in? Maf first so it gets a good solid reading the BOV or should i do it the other way around? Tried looking around some, and didn't find much input. One site saying one thing, and another saying another. So i'm asking around and seeing if there is some common agreement.

I don't know much about 3Ss, but on my dsm I'm using a translator and GM maf, and I have the bov infront of the maf. I assume the stock setup on a 3S is similar to a DSM where the maf is infront of the turbo?

I assume you are talking about a GM MAF...if so put the BOV before the MAF so you don't have to have it routed back into the intake pipe. The less welds, connections, etc you have after the MAF the better; that way if you get a boost leak you have a better chance of your car running properly.

Yes, yes, yes.... spent all that time thinking how to word the question and i forget to leave out 2 letters... G and M.

I've got the MAF translator sitting in front of me, just have to get a MAF from a vehicle then i get to start working on the install part of it soon. Also heard that doing the bov after the maf will give you problems with both turbulent air and faulty readings for the same reasons you've listed here.

The 3/s has a similar intake to the 2g's, infact the same maf translator that works on the 2g's also works for the 3/s's. Been checking the forums for some time looking for a darn 2g, but all that came up were 1g's.

Is there any amount of space i should provide for the bov? Six inches to a foot maybe? Or more if i can allow? Still in the air on how i'm going to set up the piping. Torn between a dual inlet/outlet up into twin 1g BOV pipes for each side before the maf. Or a 3" FMIC from the front straight back to a single Greddy type S which i believe was giving me compressor surge before anyways.

You should buy a AEM EMS, the car would run so much better, you have no idea.

Maf-T's aren't bad, and it really depends upon who tunes the EMS.

I have an idea on how to tune, but for the first time i'm thinking of paying someone and having it done right. Car will be logged, and should make adjustments easier for both the tunner, and me in the future... however now i'm starting to have my doubts on the 14b idea... back to the drawing board.
