Leaf Blowers as Superchargers!
 

Have the guys at Hot Rod been watching too much Red Green?
Tough to argue w/ cheap Hp but their engineering kinda blows!

I bet there is something to this. I dont think the leaf blowers are able to create a signifigant amount of positive pressure,they can just move a lot of air if there isnt much restriction,kind of like how an &quot;asperator&quot; on a Detroit Desiel that just pushes fresh air into the 2 stroke engine at low speeds can be spun faster and turned into a supercharger on 4 stroke engines. I figure that it because the impeller isnt moving fast enough,and is probably direct drive to the engine. If you stepped up the speed via a gear set it might actually make boost,even with just one. Of course the blower impeller would probably explode if your quadrupled the speed. Maybe a strong electic motor turning about 5000 rpm with a 1:20 gearset on it would really make some boost if you used a good steel housing/impeller setup.

This would be great power at the flick of a switch. An air intake tube between the blower and throttle body/carb with a Y in it that had a 1 way flapper that allowed air in when the blower wasnt running would make it work. Hmmmmm??

Mercedes Benz has electronic motor powered Superchargers.

Great link Stefano!
Not Benz equipment though, aftermarket units for different applications including MB cars.
Cheap HP, I want one!!!

The aftermarket electric supercharger goes way back! I remember about 10 years ago discussing this at length with the Pontiac guys, many were wondering if these glorified leaf blowers could supply enough air for a big V8.

The company is called e-Ram, and while their product seems to be valid, the cost per hp is not very appealing.

Cool idea though, and I think anyone that's ever thought about this when they're blowing leafs in the yard (that time of year around here!) wonders whether they could build something like this. The e-Ram develops 800 cfm and 1 psi, and is very compact. Imagine a couple of these mounted around the core support area, tucked in the corners, and couple 66-69 Olds W-30 style hoses running up to your sealed air box. Hmmm.....

While they can generate some positive pressure in a sealed air cleaner housing, it takes a lot more air flow than that to generate a positive pressure when a big V8 is gulping 800 cfm of air under full throttle.

A friend of mine owns a carpet cleaning company and they use twin rotor roots type blowers to supply the vacuum. They are belt driven with a small (10 hp) gas engine.

Now how do I convince him to switch the intake and exhaust tubes and route them to the air intake? [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]
