      Tempted to do what you were doing mike, and just run a belt w/ no idler

      Well, scored a wide band for a decnt price so I'm going to stick that in and see where its at. I have a 3.12 pulley too that I might throw on to lower the boost to a safe level for now.

      Hey guys! I have a few questions:

      1. Does anybody know what size of belt do I need to use if im running no p/s with a/c, 12 psi pulley and double idler pulley??

      2. And Here is my major question. I have a BIG!! problem with my set up! I have a 98' vr with a v1 blower and 12 psi pulley, stage 2 c2 software, 4'' maf and 440 green tops and when I hit 6+ psi or 5000 and up Rpm's the car goes WAY LEAN!!! And I dont know what it can be.

      If you guys can help me I will appreciated so much!

      Just found out I've got a pinhole leak in one of my heater hoses
      Leaving for H20 in under 24hrs, so it looks like I've got my hands full after work tomorrow

      1) The easiest way of determining your belt length is to get a cloth measuring tape and run it in place of the belt itself. That will give you the most accurate sizing of all.

      2) How are you determining your engine is running lean and at what A/F ratio? What fuel pump are you running? Does the engine have cams? If so what duration?

      C2 440cc file has more then enough fuel to support your boost level.

      Thanks for the info on the belt length...

      Well I'm determining my A/F Ratio with my AEM Wideband... It goes between 13.2-14 when boosting more than 6-7 psi or 5000+ RPM. Although it idles between 11.8-12.3

      My car has 2.9 clone intake mani, 263/264 cams with full 2.5'' exhaust and ported exhaust manifolds and an ECS fuel regulator

      I have the C2 Stage II file, and I know it does the fuel cut at coasting in gear above around 2000RPM, but what should she be running when coasting under 2K RPM, coasting under 2K she goes mostly full rich and gives an annoying bucking type feeling.

      I have read most of this thread and decided to do this s/c thing. I have a few questions? This is going to be a v1 single idler

      1. I would like to know the part# for the vortech idler pulley mine seems to large I cant fit the belt in between it and the Alt.

      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

      I have a single Idler set up. Its a vortech pulley and it is pretty tight between the idler and the charger but there is plenty of room between the idler and the alternator.
      Not to say my setup is right either tho... I tried to put a bigger 3.12" pulley on my charger and couldn't cause the idler haha. So I kept the 2.62 and will be installing my Wideband tomorrow to see whats happening.

      I made it to OC and back but I scanned my car on the way back just to see. Stored a p1158 Long term fuel trims lean... Ever since I got the c2 chip it would always run terrible for a bit after reconnected the battery or clearing codes. I think I'm going ot have to swap to known 30# injectors and see what happens. Not sure I should trust some of the vortex clowns.
      If only I invested my money into something more practical then a VW....

      The shell is junk so all my efforts have gone towards the powertrain to prepare for a swap.

      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.
