      So I was bored and looking around and came across this picture...



      I have thought of a design like this since Neuspeed did it for the MK4 2.0... Curious as to why I really have never seen it done prior to this car. I guess obviously because of ease of installation of a turbo kit and not needing to fab but surely there has to be people like me who prefer superchargers that have access to machining equipment?

      I guess I am just impressed and would love to do a setup like this myself but only lack the ability to mount it... I guess rain tray would have to go in a Corrado for fitting

      That blower is an Eaton M90 twin screw blower from a Ford Thunderbird Super Coupe. The only reason I can guess why that person wanted to run a blower like that is so later on down the road he could run the Eaton M112 or a 2 liter Whipple. Either way that a pretty cool set up. Personally I would just slap a turbo to it and call it a day.

      Nope... I plan on putting a VF stage 2 in around end of July. I already have a BT in my MK4 and Ive been bored with it. I want something different with my VR and I really started liking superchargers more when my Dad got his SLK230 and let me test drive it.

      I mean I guess you could run a barrel style AWIC en route to the throttle body.

      We have motors with manifolds that bolt either to the front or the back of the head so i Don't think that would ever work on a,well atleast older vws. I don't know anything about newer then mk4. That eaton in the pic also came in a sho I think. I got mine from a c230

      What charger it is was never in question but since they can get the Heaton back there then an Opcon Autorotor or Lysholm would clearly fit. If I didn't have so many turbo parts I would love to try fabbing something like this.

      If there was a question Eaton is a roots type charger with two 3 lobe rotors where Opcon and Lysholm use a twin screw designed by Opcon that is one 3 lobe male screw and one 5 lobe female screw which is actually the most efficient superchargers on the market! ...I don't count centrifugal cause they're junk

      The SHO was N/A until the 4th gen. The 4th gen SHO uses the new EchoBoost turbo v6.

      I totally agree about the efficiency factor. I got my eaton because F the glader need to get a W/A intercooler then ill work on suspension /wheels.

      I don't know about that dude. Pretty sure they were super charged., my buddy's neighbors had a 95ish sho.

      eaton m90's are garbage, try a magnuson mp90. i picked mine up for 350 and it is comparable to the MPX case that they use with eaton m90 rotors. i just built one for my buddies 90 tbird and we're running 20 psi on the sucker.

      New Dimensions did an Eaton/Roots type VR6 supercharger kit for the Mk3 VR6 back in the day. Didn't fit in a Corrado VR6 because of firewall location, without doing some significant cutting & welding of the firewall.

      Was a nice kit though. I've thought about doing one of those new 4 lobe deals on my R32 in a similar fashion.

      yea id rather see a centrifugal setup.

      Screw chargers on VR6's are not worth it. A proper sized unit that would match the engines displacement, would make so much torque that even an 02M would not last very long. 400-800 wtq @ 1600-1800 rpm would turn every drive train component into twisted aluminum and iron.




      But do not let this stop anyone from doing it, I would love to see the carnage

      So the company who makes twin screw chargers who is easiest to get a charger from imo is Whipple. So here us what I am looking at..


      Model. W175AX
      Displacement 2.9L/rev
      Max Continous RPM. 18000
      Max Peak RPM. 18000
      Max CFM 1720
      Max M^3/HR 2922
      Max PSI 30
      Peak VE 99
      Peak AE 78

      Whipple initially used this charger size on the terminators (03/04 Cobra) but later found the 3.4L was a better option for the displacement. I also looked at the 2.3 but ultimately I don't think that would be quite enough.



      The base dimensions are 403mm long x 197mm deep x 128mm tall. When I return home I am going to pull the prints and try to grab carboard to make a mock supercharger. Red Corrado should have the engine in the following week, if so I am gonna look for inlet and compresssor outlet options to see if this is a feasable option on a Corrado instead of just being turbo...

      SLS as I remember made a kit including m62s. That's where my kit came from originally.

      The 2.9 would work, but from my experience with matching Vortech units to VR6's, you want to use what most V8 guys use. So run a 3.4l unit.

      M90's were used on Jaguar XJR's but were maxed out on that 6 cyl at only around 8psi. They step up to the V8 superchargers due to the M90's being at their max output.

      With superchargers you will only want to run @ 70-80% of its max output. Anything after that and they start suffering from unusual fast wear on the bearings and seals.

      I had already taken all of that into account. Being an avid lover of Terminators from when I had my 2003 Cobra I have stayed familiar with them... Actually once I get closer to what I made before I took a huge pay cut to switch professions I plan to buy another...

      That's 600+ RWHP on pump fads with the same charger I mentioned in this thread. Mind you this was also used on a 4.6L V8 and not a 3.0L VR6, I'm sure it'll move enough air

      Mind you if it happens on my car, my engine is fully forged at stock compression with the initial intention of going supercharged
