Yes!

 

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.

 

To take off the magnet you need the special puller tool from mb

 

This would require some extra module to communicate with the TCU and the "bypass-flap"... Something to think about long term, but definitely don't see this coming in the near future.

 

I would love a blow off valve. I so miss my built WRX!!!

 

Why?
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.

 

The clutch doesn't disengage as often as you'd think. The 6 cylinder version of this engine behaves the same way.


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

 

Part of what you're describing is the fact that C mode starts off in 2nd gear. I personally don't notice much of a throttle response difference between the two and my car is tuned, but you'd need something to control the valve with the throttle. The concept sounds simple, but it's going to require a lot more than that to be able to integrate it with the car's natural functions.

 

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.

 

Yea you can baby it to get it to engage later.

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.

 

That is Badass!

 

My thoughts exactly.

 

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.

 

Very smart setup. I like.

 

That is almost identical to Kleemann. They use a vacuum/boost actuated bypass valve. It is the smoothest transition you can get.

Ted,thanks for the props! We need to get together.

 

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?

 

If you choose to drive with a 200mm equivalent than you best have logging SW on board for safety

 

Yeaaah i hope the guys from Eurocharged will find a solution for that.
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. :-)

 

I'm sure he will answer but it says it can be installed without the magnet in the first post. I would like to pull the magnet as well. I am worried about the appearance though. I don't want it to look like a plate balanced on a stick. Maybe machine off the large base area so it looks more like a standard pulley? That would also save some more weight.

 

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.

 

nice work fellas

 

Alex I agree but it's a hassle on these cars to jack it up remove the engine mount screws then jack up the engine change the pulley then put everything back
Not like a mustang lol

 

Just need a hub with interchangeable pulley sizes. Definitely doable.
