      To h20 obviously haha. Stayed on 14th street saturday night. Parked ont he highway for the show in sunday. Don't have any good pictures really but it was a POS spraybombed red Gti with a blonde in the pass seat.
      The shell is junk so all my efforts have gone towards the powertrain to prepare for a swap.



      Edit::

      Now has a PA plate, early Jetta OEM 2piece grille, No roof rack, 16x8 all around, and a duckbill instead. And a revised intake setup

      Has anyone considered running one of these?


      You can get them for $150, in 6 & 8 rib, anywhere from 2.7 to 3.33 diameter.
      Not only are they slotted, but apparently the slots are tied into those holes you see, creating a vacuum on the belt.

      I am considering one before the season is out

      been pondering at the idea of putting my maf sensor post s/c so i could just run a filter directly on the s/c. we (mk4 vr's) have a "hot wire" style MAf correct? anyone with a s/c vr do this? i know most of the software for our kits call for the MAF to be before the s/c, but if we have a hot wire maf it wouldnt matter would it? (because the denser air will remove more heat from the wire indicating a higher mass airflow)

      iirc people used to have ****ty performance from post-blower MAFs.
      That's a crapload of hot air being shoved through the thing.

      standalone to remove your maf and all that pipe

      i wonder why. maybe because of too much turbulance? im tempted to try it out. just wanted to see other peoples opinions and get some facts

      this is stright from WIKI for a hot wire maf:

      If air density increases due to pressure increase or temperature drop, but the air volume remains constant, the denser air will remove more heat from the wire indicating a higher mass airflow. Unlike the vane meter's paddle sensing element, the hot wire responds directly to air density. This sensor's capabilities are well suited to support the gasoline combustion process which fundamentally responds to air mass, not air volume.

      this is pretty much saying it doesnt matter whether it's pre or post s/c because pressure doesnt matter correct?

      Early AMS kits were designed to run the MAF post supercharger. They ran excellent, but again.. it was tuned that way and was low boost. Turbulence is definitely an issue, even more so with newer style MAFs.

      Although it is cleaner and simplifies quite a bit. If you want to go through the trouble, ditch the MAF, run a MAP and go standalone.

      if pressure doesnt matter, and you have the same amount of air (just more dense) what would be different in the tune?

      The MAF will handle pressure to a certain extent, but under higher pressure it freaks out when run like that.

      Granted.. if you were to switch to a different sensor. I suppose the Bosch V8 or Hitachi sensor with supporting file may be able to handle it.

      does this mean it doesnt matter whether it's pre or post s/c on a low boost application?

      edit: here is a pretty good thread on the subject. there is a guy that put his once pre turbo maf to a blow thru maf and worked fine. It was a mk4 2.0t, but the actual maf sensor is the same for the mk4 vr http://forums.vwvortex.com/showthrea...post+turbo+maf

      I've seen & ridden in quite a few "non-ams" chipped cars that run the maf post charger & they don't seem to have an issue.

      Plugged cat? I had the same problem last year. It wouldn't fall on its face but everytime I would hit around 3k rpm it would completely stop accelerating. I even had troubles getting up to 100km/h.

      Na...im straight piped.......drove it to church sunday morning it only 6mpg without me ever pushing it into boost....gonna get an afpr and try to pull some fuel... .it smells like death and evertime you rev it it leaves a black sut on the ground.....

      o2 or o2 and MAF. Has it been running this bad since you installed the blower or just recently?

      Is there a chance you installed the MAF sensor backwards?

      2: I also have a dual idler bracket but no pulleys for it would anyone happen to know the part numbers for them i see a large and small one. Also would i need a diffrent belt other than my single idler one?

      I am getting all the parts for my kit gathered up I have a list off all the parts and part numbers including the small stuff like fittings and lines hoses and tubing and such. When my kit is finshed and running and has the bugs worked out I would be more than happy to post it up to help people along


      Thanks In Advance
      So got it all running but its running way rich. At wot i get a bad surge and black smoke. I think my problem is I dont know what tune I am using or injectors lol. It was sold to me as a c2 stage 2 #30 but no sicker on it and no way to tell if it is. Also my injectors are all black with the bosch # ground off of it. I am running a dv from a turbo volvo, v1charger dual idler and noticed when i clocked it there was no oring or anything on the housing. Should there be? I have a 4" maf but i am ruuning the stock one as low as i can with a filter still on it. Also make no boost untill 3000rpms. So right now its looking like i should have spent more money at the begining instead of piecing all the parts together as cheap as i could.

      Also wanna add i have 262 cams portmatched upper to lower, test pipe with thermal r&d exhaust.

      Just since the blower install...But yeah now that i think about it...it was a little wealthy before the blower...every blue moon i would get a fuel stench for a few hours...and yeah theres always that chance of human error....I might have reversed the maf....But hell i didnt think she would run at all if i had it (maf) in backwards....as soon as i get it right and do my two weeks at work i'll post some vids....
