Nothing is ever as easy as you hope its going to be....
I finally have an idealized version of the jack shaft linkage, shaft supports with TPS and accessory mounts, and everything according to my model should fit like a glove.
Print the model, and it fits great on the supercharger. I am really liking the look.
Go out to the driveway and plunk a manifold down in the test mule, install the throttle inlet assembly and it fits! Then on closer inspection, it just barely fits. Note the clearance between the throttle shaft support and the fuel cooler.
That support cant move to any other location with the 37mm off the shelf linkage arms I was planning on using.
So, after much head scratching trying to calculate range of motion, binding points... etc I just said "screw it" (pun mildly intended) and set off to design my own linkage arms. The design challenge here is creating one arm that will work in all four locations so I can reduce the tooling and part cost.
After several attempts, I think we have a viable solution. This modular arm allows me to install a spring/stop screw. Modifying the throttle housing around the bearing gives me easy adjustment of both the throttle blade resting and full open positions independently. I have removed 7mm of radius from the arm, so I can move the jackshaft and mounts forward and now clear the pesky fuel cooler.
Progress is made when you run out of cash for machining, but still like finessing the models for that hopeful day you win the lottery.
What are you talking about? That TOTALLY fits! I think mine might actually rub in the GT! (I didn;t say that)
Its close, but the first time someone did motor mounts or a torque tube swap, that bracket and shaft would certainly become a casualty. It would be just fine if that monster nut wasn't there.
Seems to work ok with the shorter arms, just need to work out all the revised brackets. I had a FPR mounted back there that the shaft is now interfering with.
What is the recommended crank position while pressure checking the intake/supercharger for leaks? 45 BTDC ?
AFAIK, there isn't one. Our engine don't have cam overlap, so you don't have to worry about it going straight out the tailpipe. You'll know if there's a leak right away. pump it up to about 15psi and listen and feel for leaks. Hopefully none!

Well. I am torn. I have put real dollars in this and am about to dump more real dollars in this project, approaching 1/2 of expected retail price. If any of you are also early adopters of Hans's supercharger I would ask you to also send money to Hans to get our units off the drawing board and onto our cars. I am selling my current VCB system and am fully expecting, sooner rather than later, a hans supercharger for my S4. Perhaps we should all communicate with each other and collaborate to get this done. Feel free to contact me via private message.

That's a great idea Jeff. Wish I could join you on Han's system, but unless I win the lottery, it ain't gonna happen. LOL. It may not be the most powerful system in the world, but for a beautifully designed and crafted "set it and forget it" system, I personally think it's THE one to get. I can't wait to see some of you guy's Han's systems installed and tuned.
Hans knows what he's doing, but he's just one guy. He'll get it there. Remember the squeaky wheel gets the oil.
I am not doubting his ability to do what he is doing. I am trying to spur on those that are also committed, and I don't have knowledge of how much they have paid in, to send in more money and get this project finished. Once I am all in, I am expecting a system. If someone else has given $1000 and is just waiting for the end to happen, that's not gonna work. We all need to be 1/3 or more in at this point. I want to get together with the others and see what their thoughts are or how we are going to finish this.
