      Dubs,
      I missed it apparently.
      What did you order?
      Thanks.

      Oh, I thought those were looked at in the CAD models a few pages back and deemed ineffective due to their offset.
      Or was that something else?

      The pics Paul made were just a quickie he threw together just to explain concept.. not true to exact #'s.
      KingVR is of the mindset that they won't work...but the very offset he is talking about making them not work is explained by me in the next post as to why I think it will *help* us.
      As mentioned, start at page 1, post 1. All the info we have currently is in this post. [IMG]http://**********************/smile/emthup.gif[/IMG]

      Awesome. I am anxious to see how it goes.
      Any word on that intake manifold you molested?
      Did you install it yet?

      That's a separate post..or ask me via PM.
      No point in cluttering up this thread. KingVR already did enough of that.

      I still need the following measurements:
      Camshaft Base Circle
      Rocker Roller Diameter
      Once I have those, I can update the diagrams. I don't know where any of my spare parts are at the moment, there's lots of unlabeled boxes still.

      Here are the specs given to me by the engineer at the company that makes the rockers, you were very close. Thanks for helping! [IMG]http://**********************/smile/emthup.gif[/IMG] -

      Roller wheel - 17mm (same as the cam base circle, go figure)
      length from pivot to valve for is 46mm
      distance from pivot to roller is 22.8mm

      17mm "Base Circle" of the camshaft is a 17mm RADIUS. The Ø/Diameter is 34mm.


      Unless my caliper is off by .98mm on nothing else but this roller wheel, check back with that guy about that being 17mm.
      This rocker is from a "BDF" 2.8L 24v VR6...which is not a 3.2L from an .:R32 but I can't see them having changed the roller wheel for no reason.

      Well this work might take a bit but I got the head side view in dxf now..

      So I can clean it up and do some of the geometry stuff more easily.

      Why did you choose to do cyl's 1/3/5 with 2 lobes/rockers showing instead of 2/4/6 with only 1 lobe/rocker and already 'cleaner'?

      Found out the reason for KingVR's different #.. probably relevant- "The roller diameter of the VW is 18mm, the roller
      diameter of the ******* is 17mm. "

      I did both that's just the one I print-screened It's going to take a good bit to clean up the drawing but it'll get really close to nailing the geometry.

      I finished, but the internet at work broke
      That's with the real base circle, real roller dia, cams with 11mm lift with stock rockers, and the smaller roller on the 'new' rocker.
      Stock

      New rocker

      All this is well beyond my scope of knowledge, but I can see 2 things.
      #1 The lift is high enough to *require* different springs if using Schrick or TT cams. Not optional.
      #2 6mm of timing difference is substantial. How it will run in the real world is left to be seen since again at least the 'error' is in the direction of 'equalizing' the port lengths.

      Anyone else?

      1) Totally and might even push the limits of some aftermarket springs.
      2) I'm not sure I buy in to wanting to use cam timing as a pulse tuning tool. You will retard the short intakes by 6deg; shifting power to low end. But you'll also, in the same cylinder, be retarding the long exhaust by 6deg. Obviously, the exact opposite with the opposite geometry. Will all the pulse effects balance out or work to an advantage and make gains? Who knows.
      Honestly, this would be better to try out on a car with stock cams just to see what the gains there are vs a set of mild cams with similar lift.
