getting confused about blow-through and draw-through MAF's???

Draw through means the maf is BEFORE the blower, blow through the maf is after the blower, and after the intercooler. Draw through is easier for most tuners to deal with, but you have to deal with recirculating the blow off (called bypass then) which can sometimes cause issues. With a blow through setup you can run an atmospheric blowoff, get that nice pssh sound rofl

Go blow through. IC wont effect it. Make sure the MAF is in a straight section of pipe with no bends or any flow restrictions/changes within 6-8 inches of either side. Put the BOV atleast 8 inches before the MAF.

the blow thru MAF is harder to tune but i LOVE the BOV!!!!

it attracts a lot of attention. i had about 10 people from my hotel at mustang week ask me what turbo i was running.

i do have terrible idle issues though

never had a problem tuning with my blow thru ProM ATI tube meter on my stock motor calibrated for 42's.. (currently for sale for a great price if someone needs one). it was bolted in the spot in the piping procharger recommends in the fenderwell for more than 2 years. my car idled like a stock car with it.

we now have a PMAS cyclone tube in it cal'ed for 75's and its not to bad either..final tune is not complete yet though.

I like the tube meters better in blow thru applications over the flanged meters. ease of install inline without adaptor plates and the fact that they have been super reliable for me are bonuses.
