I don't have that much straight before it as you can see, but it never gives me any problems. I'm still running the same mafs as you see in that picture, longevity doesn't seem to be an issue. Looking at those pictures brings back some good memories lol. My setup has come a long way over the years.

all shal perrish, with a tuneable ecu you should be able to tune it no problems.

i thought so..
i knew i could tune around it,
however.. maff turbulance would have just made it that much more of a pia...
so, now that i know that.. time to start getting pipeing.
thanks..

probly in a month or so when i am turboed, ill post up some picks of how i did my blow throught set up with a ebay core and probly custom piping..
cant wait to see how that h1c acts!

Bumping this back up bc I have a quick question. I just went blow-through today and I love it so far, drives so much better. I'm going to boost leak test it in a couple of days and I have some epoxy. I was just wondering where you guys put the epoxy/window weld stuff... just on the outside of the connector on the maf and then put the plug on? Maybe a bit extra on the outside?

I just found my Z32 MAF is leaking from the circuit cap. :evil: It started yesterday while I was on the FWY, then out of nowhere when I stepped on the gas the turbo did not spool and it felt like it was N/A. I got off the FWY and it iddled and drove fine, just no boosting.

Where can I get this windshield stuff? Glass shop?

1 - Are you running a FMIC?- yes

2 - What boost levels do you usually see?-

15-18

3 - How long are your MAFs lasting?- never replaced it

4 - How long have you run Blow through? (kind of the same question as 3..)

Bout a year, prolly 2 or3k miles.

5 - What MAF are you running? z32 maf

6 - Where on the cold pipe is your maf located, how far away from the TB? Is it on a strait peice of pipe?

Actual sensor square portion is just below battery tray. Tb is relatively close cause of my IM. I prolly have about 3-4 in before and after of straait. Which is less than what "people" say you have to have, but still no problems with it.

PS.
1.Things that should also be included. If your running blow through dont recirculate your pcv, you will most likely go through sensors quickly, and or have to clean regularly.
2. My method for sliding a coupler over the maf was taking a flap wheel and just shaving the flange down. I was able to retain the mesh and still slide a 3in coupler over it with ease.
3. Blow through is the ****, i dont understand why people put it on the intake in the first place to be honest. I've never had a more rock solid idle, and absolutely no stalling issues. Not to mention you have more intake options if you have a 4in inlet, no more bottle neck from the maf, and no more filter if you dont want :).

My blow thru maf had a straight section of pipe b4 and after with the old cold pipe setup.

since i re-arranged my cold pipe, now there is a 45 deg coupler attached the maf sensor b4 it... so now there is NO straight pipe b4 it.. But after it there still is a straight section. My a/f ratio's didnt budge after hitting it with that 45 deg b4 it...

if ur on a blow thru setup and ur bov is on the cold pipe, then u would put the maf after the bov... closer to the throttle body. If you have the room to fit both on the cold pipe, if not then move the bov to the hot pipe...

yeah the lightning MAF would work, to run with a JWT tune you would want to get an safc to fine tune. and tell them that you are running blow thru (although i dont think it will matter much, idk if they can compensate for it)

what happens if you put the maf in front of the bov? it would go throttle body, bov, then maf?

then youve defeated the whole purpose of blow through. you'd be back at square one, blowing off metered air......

I have a question on this, so all i have to do to run blow threw is put the maf on the tb side of the intercooler? how far does it have to be from the tb? This looks very interesting i might do this, is it fine on a bottom mount?

Guess I should do my duty and 'check in'. Of course only 5psi so haven't blown any couplers off and only driven the car 7-8 times since turbo install, damn winter.

JWT with Cobra MAF.

Just converted to blow through last night. It doesn't appear to be giving me any problems at all so far. It's not even running lean.

Ok, so what's the aveerage boost pressure where the couplers start blowing off?

I plan on using hair spray if needed when I up the boost to around 10. No issue at 5psi so far.

I've blown off a coupler once. It was just an unusually cold night, it hit about 15lb's. The tbolt just wasn't tight enough. The maf housing is surprisingly strong (plastic z32 maf). You can tighten the tbolt down pretty good, just make sure you are paying attention. But i've held 18psi multiple times with no problems after that incident. You really shouldnt have any problems at all.

Is the cobra maf housing aluminum or plastic? If its al you definitely wont have a problem, or atleast no more than yo would with a tbolt on any one of your intercooler pipe's.

Ps lol. I like your sig. Glad im not the only one.
