g-spec: is that with a stock charger or ported? what size pulley? i like the twin intake for the fact that you can run two OE air filters and still get excellent flow, but filter out all the tiny particles that cone filters allow in to the charger.

If you like the idea then go for it....I was just saying that no matter how well it is ported and how small the pulley one intake is more than enuf. Two OE air boxes would take up a lot of room possibly making it hard to run intercooler piping. I actually want to see someone pull this off...cause I think the car would make good power thru the whole rpm band. One thing I would be worried about runnign the g60 on a diesel is the vibration....running a one way pulley would most likely help and would be a good idea....the g60 is very fragile in that way....thats why all the aftermarket chips move the red line to about 7000 so that you dont hit the rev limiter cause it can damage the charger.

can you give me a link to this data? i'm intested to see. i tried two intakes on my old corrado but i didnt have it set up like i wanted. i had narrow intake pipes and cone filters -- not an inner pipe diameter the same as the charger inlet diameter and no OE airboxes, as desired.
it comes down the volume of air that can theoretically pass through a completely ported charger with no air filter at maximum (safe) charger RPMs. from there reasonable compromises could be made... ie: type of filter(s) and what size of pulley to achieve maximum charger RPM as maximum engine RPM is reached. this would allow for maximum flow without needlessly harming the charger (ie particles, over-rev). please send me a link or some data if you can.

ps: max charger rpm = 14,800
(with standard G60 belts/pulleys)

Maybe also isolate the 'charger with some rubberesque bushings to counter the vibrations? A one way pulley and some isolating bushings, should cut down on a good deal of the vibration problems I'd think.
I'm kinda interested in the supercharger idea myself, but take it a step further and put it on an electric clutch as well. It's there when you need boost
now, but for just cruising along the highway you can flick a switch and take it offline to reduce drag on the engine.

i would think that the G60 supercharger would absolutely need the one way pulley... just imagine the carnage if the supercharger was spinning full load and the motor cuts out... ouch!

if i was doing it i would use one of those magna chargers that bolt on the back of the head in place of the intake manifold, this would make it super easy has nothing else would change, the only downside is that you can't run an intercooler. but it would make for an easy install
Do you know how many magna chargers are left in existance? I know of 3 maybe 4! those are more fore a collector! i would not want to use one for everyday use ! now that was the best dam forcedinduction equipment ever made in my opinion!! but i gotta settle for a G60 they are more plentyfull and parts are ore available! thanks Duane

I myself still have an actual add and sales lit for that particular kit SOMEwhere,...

dan always had all the best stuff. i don't know how he does it. that charger is very expensive and i'd be afraid to drive it hard with such a collector piece at stake. that would obviously be a simpler way to accomplish a SC diesel... who's got $2k US to spare? lets see it done! if you don't blow up the charger you could always turn around and sell it............

Why not try a G40 charger off a Polo? mine produces just shy of a bar of boost on a 65mm pulley and its smaller in size that a G60, plus you can modify them to run a single inlet and blank off the other

Where to get one on this side of that Atlantic though?

I like this idea
I posted about it on Vortex but just got flamed a lot, even tho Volvo Penta do exactly this setup on their large marine engines.
You'd definitely need to run supercharger
and turbo since the G60 can only about a bar of boost before it explodes.
But, how about using an Eaton from a Mercedes? They are cheap, plentiful, smaller than the G60 and considerably more robust. Plus the M62 from the E & C230 comes with a magnetic clutch! Only makes a bar or so tho but still...
Anyone got any ideas how you would switch from one to the other? I can't work out how to switch the blower off when the turbo is up to speed without losing boost. Also not sure how to do the plumbing since when you switch the blower off it will block the airflow to the turbo. How does the twincharged Golf 1.4 do it :?:
Fab idea tho! Especially since I have an M62 in the shed

I recorded the max boost on my G60 car after the charger had undergone 'stage 4 porting' with a K&N air filter and 68mm pulley as 18psi, approx 1.25bar. The original VW Digifant I software is really only capable of handling boost of up to 1 bar, maybe thats where you're getting the 1 bar number from? That was reliable and repeatable no problem, sometimes 19psi and I'm sure it could have been pushed harder. I don't think too many of us would really need any more than that so I'd like to see someone do it even with just the G60, no turbo. But a turbo as well would be great of course, that just complicates things a fair bit.

1.25? that's 'about' a bar :lol: ish!
The 'about a bar' came from Jabbasport in the UK, the theory being that you can only spin the charger so fast before it goes pop, and that limit will make about a bar or so. So a stage 4 making 1.25 is about right.
How much power would a TDI make on 18psi? Don't you need rather more than that for real fun numbers?
The Eaton can make 18psi too, although it gets rather toasty at that sort of pressure! Thats why I'm thinking twincharged - lower boost from the Eaton and a hyuuuge Holset
