Then remember that you have the tension on both sides of the pulley- so double it again! Also, that force is cantilevered out significantly far out there on the blower nose- it's going to create a moment around the entire part and load up harder on that end cylinder... I can't really tell where you are applying the load, but it may be something you want to check.


      Also, have you considered the dynamic loading created by blower drive torque? Vibration will be a major issue as well I think with that heavy of a mass hanging out there... I would check the natural frequency as well- it may be low with that big old mass out there and a sufficiently soft / springy system.

      Food for thoughts.
      Thanks for the input. The 50lb figure was just a guess as this isnt a "real" test anyway because I am going to support the plenum as well, not just bolt it on. I applied the force (weight) of the s/c in the downward direction along with gravity, and the belt force I applied perpendicular to the direction of pull on the nose of the s/c, therefore solidworks takes into account the torsional force from having the force on the end of the s/c. If you look in the last couple models you can see the stress is higher on the runner closer to the nose of the s/c.


      I have been doing more research on other s/c (roots) kits for hondas, cobalts, etc. (4 cylinders) and looking at the intake designs on those and they seem to have a much smaller plenum feeding the runners. So I might try that with the new design, mimic something similar to what another company has done.

      If I am able to make the plenum smaller I will be able to add better bracing on the manifold.


      Something similar to this with more runners
      http://tykoh88.blogspot.com/2011/05/...arger-kit.html



      I am not able to do vibration analysis, because I dont have that capability. Although Im pretty sure we are about to upgrade at work, which will include vibration analysis. I dont think this will be as big of a problem as the end of the plenum will be supported. You mentioned the weight hanging down, and that part will have supports running to the motor, so it wont be hanging. I would agree with you otherwise.


      Thanks again for the input.

      Reading this thread is always the highlight of my day.... I have NO idea what you guys are talking about half the time but it's better than reading about offsets and suspensions

      Hopefully some day soon I will be sending you guys my ecu for a tune and getting some bigger injectors.

      This made me lol. Talking suspension bits is pretty lame once you start digging into a custom supercharger setup. I'm always fascinated at the capability of modeling programs. It really makes me want to learn how to do it. Keep up the good work!

      It is amazing, the capabitities of modeling software. And it has come so far in the couple years I have been using it.

      IMO anything custom is interesting... well to a point, even suspension.


      I thought about this the other day, and I have only owned a VW for a couple years, but I have been into cars/motorcycles for a while and it blows my mind at how few people in the VW "scene" actually do custom work. Most people just buy parts, and either have a mech friend help them install them or pay someone to do it. I am very greatful for the 2.5 guys that post regularly on here, they seem to be the exception.

      But I guess the more computer controlled cars get the less that can be done at home.

      This project has been put on a little bit of a hold, I am finishing up some house projects and I also want to finish a couple more new things for the car before SOWO.

      I dont know if I would use the word producing.

      I put this on hold since I will not be able to finish it by sowo. I wanted to get a couple other smaller/faster projects done before the show.


      But after the show I will get back to work on the s/c. After seeing the little tweeks I need to make I would rather make sure all my clearances are good before redesigning.. again. So Im going to use some green foam to get a cavity size and go from there.

      Then its just 3D print, cast, and machine. Oh and add a couple more hours to the day to get all that done. haha.

      Sad to hear it won't make it to SoWo but it's a WAY better decision to leave it at home, take your time and do it right than to rush it and risk the whole project.

      Me too! I can only do so much in the couple hours after work. Some day it will whine.

      I recieved a card from a casting place at a trade show I went to last week. So I sent the 3D model to a casting place, just for the fun of it, to see what they would charge for a cast rapid prototype......


      $6,000! haha

      Yes it is

      My pockets must not be as deep as yours, $6000 is expensive. haha.

      But I definitely understand why it is that much for a one off. I just had never price a cast part before, and wasnt expecting that.
