Does anyone know if there is (or will be) a supercharger made for the 147. I know you can get the Autodelta turbo kits but I was just curious about the supercharger - not that I could afford one at the moment

As far as I know, the supercharger is driven by a belt, while the turbo is driven by the exhaust gases from the engine, and because of that, it needs a certain amount of gas to start working, therefore, the "turbo lag".
Hope that helped.

You are right Ant. The Turbo is driven by the exhaust gasses, it's something like a turbine driving a centrifugal compressor.
Modern small Turbochargers have almost no turbolag, but if you want serious power a larger Unit is reqired, which unfortunately result in some turbolag. The advantage of the Turbo is the fact that it uses the otherwise wasted energy from the exhaust gasses.
Superchargers come in two versions; centrifugal chargers or the Roots Type charger.
Centrigul chargers ( Used by Engstler, and probably novitec ) also need to be revved like turbo cars to perform. But there's no lag as they are belt driven). They are also small handy units as the turbo. They deliver a smooth increase in power following the engine revs wink .
The Roots type Supercharger, doesn't rely on the centrifugal effect in order to pump air into the engine. It's basically an airpump that compresses the air, even at idle, which means that it delivers low down "grunt" all the time. Meaning an impressive amount of torque. The backdraw to this type of supercharger is that it's larger, heavier and more expensive than the Turbo charger or Centrifugal Supercharger. Plus it consume some Horsepowers ( up to 50 BHP ) when it compresses the air.
All the best

PS. As you might have guessed. I'm in favour of the Roots type. And surprise ; I have bought one. It's sitting on my workbench awaiting me getting a grip, installing it.

Cool Hoygaard!! Nice explanation... when u say consumes horsepower.... does this mean you loose 50 or gain 50???? Or am I being dumb!!!!

Using the supercharger of course gives you extra horsepowers, but running it uses some energy (Horsepowers).
As for the turbo, the engine pushes the exhaust gas out anyway, and this work is wasted. But by fitting a turbo you can take advantage of this energy.
The amount of power a supercharger need is of course depending on the size and the pressure you require. The latest version of superchargers from Eaton have a bypass valve, enabling recirculation of the air. This saves energy when the engine isn't under load, ie when idling or at normal cruising speed. when the compressor is recirculating it uses less than one Horsepower. wink
Hope this helps

BenDy, the supercharger from Novitec is about £4k from Novitec. Buy one and get it fitted and I'll pop over to York. If you could do it by the end of today that'd be nice as I'm photographing a wedding in York today!

Guys, for a given power increase, does one type (turbo or supercharger) lead to higher fuel consumption than the other. Also, how about reliability and longevity? wink

As the supercharger itself require some power.
The Turbo charged engine probably use a little less fuel, at the same power output. But when the turbo engine isn't under boost, the Turbocharger will act as a restrictor in the exhaust system. And then maybe use a little more fuel than the supercharged engine.

All turbochargers are maintenance free, and so is most superchargers. Some Centrifugal chargers need replacement of an internal cogged belt from time to time, but most Roots type chargers need no servicing.
As for durability. Turbochargers have been around for ages, and Mercedes is factory fitting Superchargers to the SLK, CLK and the more ordinary C-class cars. And if Mercedes believe in them, I reckon we all should ( But then again, Mercedes also put their badges on the VITO, eek! that's beyond me!!)

back to topic:
I think there is two extra differences between a supercharger and a turbo which is: a) the typical sound both produce and b) the way they deliver the extra power.
The sound of a supercharger is very nice, but when it's delivering the extra power the noise of the supercharger is on the foreground and you can hardly hear the noises the twin spark engine produces anymore. The sound of a turbo on the other hand is not on the foreground, it just adds a whistling type of sound to the noises the twin spark engine produces.
If you give extra gas, the supercharger delivers the extra power without hesitation, the turbo delivers the extra power after a very short period because it has to build up the extra power. The hesitation in the power delivery is called the turbo gap. Theoretically the supercharger is the one to go for because it lacks the turbo gap and deliveres instant power increase. But a little turbo gap is no that bad because it gives you a kick in the back when it suddenly deliveres the extra power which is very nice to experience.
