Electric Supercharger Options

[VavAlephVav]

Wondering what experience anybody has had with these little electric supercharger systems like this one,

http://www.streetbeatcustoms.com/RAM/Super...r-System/18149/

says it makes 1psi boost and gets 15 hp. surely not as much boost as a nice supercharger,
but at $400 compared to the $6,000 kit for a supercharger, I may have to at least consider it ya know.

A leaf blower has a turbine inside not a fan. The vanes inside your brake rotor work the same way. A leaf blower could build compression, but in reality it is built for moving a large volume at a low pressure. To build pressure you need extremely tight tolerances, a leaf blower probably has a gap between the blades and the housing that could be measured in quarters of an inch. Your oil pump has .001's of an inch clearances if I remember right. It needs such tight clearances to build oil pressure for the motor because oil would just flow backwards through any gap and not build any pressure. Now consider that oil is enormously thicker than air and there for with its lower resistance to flow much more likely to slip past the blades of the impeller.

Lastly consider a turbocharger rotates at speeds over 100,000rpms while a leaf blower has the impeller bolted directly to the crankshaft or motor, meaning its not going to be spinning faster than maybe 10k rpms or half that. The vanes are moving so slow that the air can just rush back past the impeller.

It would improve the function of the engine, but the cost and complexity of installing an electric turbine or leafblower far exceeds the benefit. Swapping motors or spending money on your cylinder head would be much more cost effective.
