You're right...but they have the clutch for that. I've never seen a clutchless supercharger without a bypass. The bypass on the surgetanks is a great idea though...hmmmmm...E500 4matic with a superchatger swap anyone?

I think the best Design for a fixed SC Pulley woulde be just the SC shaft with a pulley.
Is this much harder to design/realize Shardul & Co. ?
That way, like described before would get rid of the heavy Magnet aswell.
Anyway, i have thought much about that new fixed pulley and yes, like others have said, the proper tune would be crucial.
I hope it can be done the way, that on the "C" comfort mode, the bypass-flap could be opened longer than on "S" mode, allowing for smoother, more lazy cruising/accelerations just the way its now with the stock clutch Setup.
Together with the start in 2nd gear on "C" i could continue with my daily driving habits, going lazy drive all the way with my 2 metric tonnes heavy car and going sporty/agressive on "S" mode or "M" mode.
Thanks guys.

Currently when i select "C" Mode in my CL 55 AMG, throttle response is totally different and i need almost 1/2 pedal way to start getting into motion from a stand-still at all.
And this is even described in my manual that came with the car that way.
I thought that this would be the same on the E55K aswell.
So there is already a communication that tells the ECU that i selected "C" mode and therefor Throttle-response/throttle-way is immediately altered.

Highly interesting for sure. But for a daily driver im not sure. Fuel consumption will significantly rise.
I remember AMGs claim that our compressor eats around +-100HP at max-RPM alone to spin.
Dunno how that is at lower RPM though, but i guess a clutch is there for a reason.
Hopefully the guys from Eurocharged can chime in here and talk a bit what their findings are.

As long as you're in vacuum fuel economy will be decent, when you're in boost that's when it goes down.

msheredy,
well on my car i do notice when the SC kicks in clearly because of a distinctive squeak sound - of course i could be possible wrong and that its the bypass flap closing in reality. Gonna check it out soon with my SDS.
Anyway whatever it is, it rarely does happen at 1300rpm, rather later when im soft on the pedal.

It's buried in the archives here but I want to say that the blower *will* engage regardless when engine speed reaches ~3000rpm (this is assuming your intercooler water pump is functioning).

Here's a pic of my SL500's AMG set up. I had my electronic bypass actuator converted to a vacuum driven unit (see pic below)
It operates the same as my previous Magnuson blower set up. I figured I'd post in case others were contemplating a similar set up.
Shardul, your clutch less pulley system is very impressive. As soon as its tested and the proper tuning is available, I'll be ordering one from you.

Interesting concept. I look forward to reading more about it once installed on a car with tuned ECU. Doubt I'll see this on a 3.2 anytime soon due to not having a blow-off valve.

I doubt fuel mileage will drop much for light throttle/cruising.
What scares me a bit is what will happen if the air to water coolant pump dies and the fuse which was the clutch can't disengage and your forcing scorching hot air into the motor under a huge load/rpm. Can it save itself just pulling timibg and dumping fuel? Even when massively overdriven with a pulley such as a 200mm equivalent crank pulley?

That thing has to be a 100% complete package with all safety features so we customers don't kill our engines
Shardul:
IF i want to pull my Magnet, can i do that and mount just that new fixed pulley. :-)

Also, with these pulleys I could see driving with a 172ish on a daily basis and popping on the 200 and installing the "race" tune at the track. People do this all the time with their mustangs.
