Types of superchargers

1slow370 · 12-23-2009, 02:26 AM

technically the word supercharger encompasses both engine and exhaust driven "turbochargers" as a device wich compresses intake air for an engine originally turbochargers where turbine-superchargers but that was ghey so we call them turbochargers.

edit: just wanted to throw out that a centrifugal supercharger is in every way inferior to a a proper turbocharger setup where as positive displacement supercharger far excced the low rpm output of a turbo charger but but lose on the top end.

Both in terms of how they apply boost and where...

In a sense...and I'm being very general with this, I see it as a worst of both worlds...but still better than no boost!

So I hear what you guys are saying, but how do you both feel when comparing the centifugal to a good single turbo set up mostly in terms of reliability??? but if you have any other input that'd be cool too..

A lot of the common downsides of a centrifugal can be overcome with good engineering and testing.

Basically, centrifugal superchargers are well known for having less bottom end power than a roots blower. However, this can be overcome by trimming the wheels and making enough changes to make sure that you have good boost on the bottom end.

It takes a lot of time and development but it can and will be done.
