Well... I figured it was time I share this.
I've been quietly brooding over an idea for a while now.... something that would force me to learn some fabrication skills and hone a few others that I have. An excuse to buy new tools, a distraction from life and something that is unique in this community. (As the years go by, unique is hard to come by - this platform has managed to do a LOT in the last 10 years.)
I contacted Mike (MD-LD9) back in the summer regarding the stock crank size because I wanted to try my hand at retrofitting a supercharger to the LD9 on my "beater" car... Sickness. He was fantastically helpful in giving me some advice on the crank size and ratios for driving a potential supercharger... one I eventually picked up.
in 1990 Volkswagon released the G40 and G60 engines, complete with a very unique Centrifugal supercharger called the G-Lader, it works much like a rotary engine. I picked up a G60 G-Lader supercharger on ebay and have been staring at it on the shelf since August, wondering if I would really go ahead with attempting this.
We are talking getting a mock-up engine, finding space to fit this thing, making mounting brackets from scratch, designing proper belt routing for optimal tension and belt wrap, piping, fueling, tuning and oiling. All the fun stuff.
Did I mention the budget for this is around the $1200 mark for all parts including intercooler, bov, etc? Yeah.
Bear in mind this is an exercise in trying something unique and challenging myself - not going for max power. That "dream" sits in the garage still awaiting a GT35r.
The reason I'm making this post is to let the community know about the project - I plan to start a thread in the photos and media forum. Thanks to a kind JCO member I received my mockup engine this past weekend and I have already started some measuring and fitment prelims so I figured why not photo document this and share it with everybody. The other reason is I'm going to need encouragement - I expect to hit some heavy snags along the way. It's too easy to put a project aside and forget about it.
With that said - if you guys have any questions or comments I'm happy to answer them.

Pics of said charger? Good luck!!!
Oh cool, its a vane type charger. I've heard of the design but I didnt think anyone ever tried making one. This'll be cool. If you want a cheap blow off valve see if anyone on the DSM forums are selling their stock re circulation valve.

Nice, I will be looking forward to this.

Gonna be a neat little peppy setup i imagine. going to be moderate torque from it?
Vince, I really don't know what to expect from it, I think some moderate torque but I think rather than beefing up the bottom end and gassing out like the M45 does it will beef up the mid-range nicely with a bit of low end torque added. From all my research this little charger makes boost very quickly down low and keeps building it to redline so I'm curious as to what the end result will be in terms of driving fun-factor. The ability to intercool it is a huge thing in my opinion and I'm curious to see its gains over an M45 setup at the same boost level. (If I can keep boost that low, I'm really doubting it.)
I am going to start a build thread in Photos & Media in a bit - I took a few VERY rough photos of the unit held where I want to position it on the LD9... I was fortunate enough to have a spare alt and H.O manifold to bolt onto my mock-up engine so that I could get a true placement and see what my real clearances are. It's tight. The thing looks like a beachball held in front of the block. lol.

I mean its going to be unique as long as you got the background and knowledge of it, which based off of what you have done previously.... you know what you are doing. Glad to see you are still into sweetness
I saw your other post and you seem to have a good idea what needs done and how to do it. I wonder how noisy of an SC it is too
Thats about my only like for an SC is the whine from a m45/62/tvs
As I posted in the other forum. About time, and good luck!

You do know Brandon (Boosted2point4) is selling his GT3582R for $850, right? and a Tial 44mm wastegate for $225. Screw sickness, let the black beauty get some lovin'! Driving my buddy's new Speed3 kicked my ass into high gear and got me back to the JBO. Don't make me finish my car only to have no local competition, Chris.
