      I'm not sure I'm following your question - the V9 intake is on the side and the exhaust points to the back as fitted to a VR engine. Turning the housing does not change where the intake is; only the exhaust moves.
      The intake pipe on mine (Corrado) has a 90 degree bend right next to the blower's intake, the intake pipe then point down and is stuck into the area behind the front bumper. I don't see an easy way to change this or I would have.
      The exhaust points aft. Adjusting the belt tension makes the exhaust point up or down a little which mis-aligns the boost pipe. That's why the charger's housing can be rotated - to get the exhaust lined up with the boost pipe.

      Thanks for the response/clarification. My intake is as you described. My exhaust (pressure) side exits at about 4:00, then goes horizontally between the engine and radiator and comes up the other side of the engine. First goal is to get the air filter up off the ground (Seattle rain). If I can extend the intake piping to the other side of the engine between the radiator and then 90 up into the engine compartment near the battery, I hope to eliminate issues with sucking water. I have also had MAF issues and thought the MAF could be relocated into a longer section of straight pipe that might eliminate turbulence. I understand turbulence may be the cause of some MAF issues.

      At a much later date (i.e. when money is available - sometime around 2037) , I'm considering increasing V9 air flow by having it converted to a "G" trim during rebuild with high speed bearings (40,000 miles on charger now but still seems to work well) and increasing charger speed with smaller pulley. From what I understand, this would be equivalent to or slightly better than the original VF Stage 2 and would likely require intercooler (considering AWIC near current battery and washer container location), larger injectors and new tune.

      So, if I can rotate the pressure side outlet towards the firewall and run the pressure piping around the back of the engine now, this would free up space for possible future modifications while allowing me to relocate air filter and reduce risk of sucking up water.

      You can turn the exhaust outlet to anywhere in the circle by loosening the one big V-band clamp that holds the housing together. The intake's center is also the center of rotation of the housing - this means the intake stays in the same place when the housing is turned.

      i have a v9 24v getting wrapped up with some cog upgrades and new cooling system and a v1 charged 12v that's getting an intercooler to go with its upped boost via 22t charger cog upgrade. nothing to fun to see in photos at this time yet, once something visually changes ill be sure to post up.

      I am waiting for the tracks to open back up to see how deep into the 10s I can go before making any real changes.

      Or I might just put the car up for sale.

      i saw your working with supercharger innovations for the cog stuff, super excited to see some supercharged VRs push the limits

      i don't think anyone will appreciate the car enough to justify selling it haha, just keep pushing I'm too anxious to not upgrade since i have to pull it apart anyway

      Most likely I will just keep it parked until I get the itch again. But if someone wanted it I wouldn't be opposed to letting it go. Plenty of other stuff I want to build.

      Found out to clock the v1(change outlet direction) all you have to do is loosen the 6 allen heads surrounding the inlet side of the charger. Once they are loose or removed you can turn it which ever way you'd like super simple. Just finally got around to it today. Now to get some piping and start planning for the FMIC.

      Hey all. I've bought (in-process) a v9 G-trim stage 2 kit from a Vortexer (skatedvs420) and I have some questions.

      I'll be running stock compression and adding E9's stage 2 cog kit (64t crank, 30t charger). I already have a UM N/A tune with TT cams (which will be staying). I'd like to stick with UM for the tune, but I need to know what I need for my fuel system. I assume R32 MAF, bigger injectors, a FPR & a bigger pump, but I'm not sure what to put together.

      Any help would be appreciated.

      2.8 24V VR6, btw

      Contact United Motorsports for specific fueling needs that will go along with their tune. I know for my setup i had to go with an r32 maf , 630 cc injectors etc etc. They should get you squared away so you know what you need to purchase.

      So I called UM, the guy that answered the phone seemed less than enthused to be answering my questions. He said (for my 2.8) to use the stock FPR, which goes against everything I've read (should be 4bar), my stock MAF sensor (their website says R32 MAF) and the 630cc injectors. That was the only thing that seemed to make sense. Can anyone help me out? I know I need 630's, but what about the MAF & FPR?

      Yeah, that's what you tend to get with UM, but they are good tunes.

      My 24v 2.8 supercharger UM tune was setup for 4bar and R32 MAF.

      Hey bud used to co own E9 can answer your questions.

      1) If youre going to run cogs, you will be required to upgrade your V9 with Race Grade Bearings which will require you to send your charger out to get rebuilt Roughly 4-700 dollars dending on what bearing upgrade.

      2) Upgrade to a UM STG 2 tune with 630 Injectors stock MA4/4" alum housing. TT cams are a good mid range camshaft that will compliment the charger well.

      3) You should see roughly 7 PSI of consistent Boost. Now that's all fine except you will want to ensure youre not using the Plastic tubing that came with the VF kits. they have been known to develop Pin holes in the blow molded plastic and can limit your performance. if you must use the plastic tubing, replace the silicone and get better clamps. I can assist you in getting new pieces for the kit. Just let me know shoot me a PM and well go from there

      4) UM uses the OEM 4 bar FPR, don't change it.... VFE uses a 5 bar... toss it out if it comes w/ the kit. UNLESS YOU HAVE A 2,8L then use YOUR stock MAF as it goes with the tune.

      5.)don't need an inline pump however you will want something as a failsafe. Get a DW65 Deutchwerke replacement In tank Pump. it outflows a Walbro as its 265LPH and is a direct plug and play into the OEM fuel connectors.

      6). You will want to look into a new clutch at some point if youre over 100k. the SC will wear it down faster, esp if you launch the car.

      7.) if you get cogs. you CANNOT 2step the car in a parking lot. You cannot free rev it at shows or soundoffs. if you 2STEP in a manner other than under load driving or on a track... you increase the risk of the bearings prematurely failing. Don't take the risk.

      8.) You will need a fluidampr, the Cog kit comes with one if you incl that option, however I can get you one as well... just lmk

      9.) Make Sure you have $1k in reserve incase something breaks or you need a rebuild for the supercharger. things begin to get more expensive when you add boost.

      Idk man everyone's car is diff. The people I've talked to report roughly 7 real world. But by the math should b 8/9.

      7 is conservative I guess .. just trying to be realistic. Now Jamals is 9 ish for sure

      I got a tune from UM and estimated to do 10-12psi depending on what size pulley I throw on..... also not sure if it's true but heard some say with straight cut gear charger you will see an additional 1psi

      The tune doesn't make the psi, ha. The pulley sizing and intercooler / piping length is what dictates that.

      Um just says that their tuning is supported to X number. Doesn't mean you'll make that.

      Also the gearing on the straight cut is 3.45 as oposed to 3.6:1. So it will make the same boost sooner. Not really more psi rather, sooner

      I know that they gave me a range the tune would be good for. I have couple different sets of pullies I'm going to play with. But the 22 tooth should get me there.

      I will hopefully be able to contribute more to this thread soon. By the end of this month I'll hopefully have this all running on my 12v mk3:

      V1 is getting sent in for a full rebuild
      14psi cog kit
      UM stage 2 tune
      Injectors
      4" MAF
      Maybe a fuel pump
      All new charge pipe with a forge DV
      New intake setup and MAF routed to driver side of vehicle

      As of right now, I've had my AMS kit running flawlessly the past 7 months at 5psi (at elevation in Denver). It's been a DD all around town, driven up to the mountains and back no problems. It's quite slow but I've had no serious issues yet with the way it runs, which has been nice considering the age of the kit.

      Check out my build thread on the car here if you're interested. Can't wait to report back with the results. Many pics and videos will be had since people seem to not be good about those with these types of builds.

      I have an OBD1 95 EA code VR6 that I have a prototype Vortech V5 H-trim I'm putting on. I have a C2 36# supercharger chip and supposedly it supports up to 350hp with just the addition of 36# injectors and a 4" Maf housing. I plan on running somewhere between 11-15psi and was wondering if it is also necessary to upgrade the fuel pump?
      I do ported/modified VR6 and 2.0 throttle bodies, mirror polish and port intake manifolds. PM me for details.
