If it produced no pressure at all, it wouldn't be able to move any air against its own inertia. It does produce some pressure, though certainly nowhere near as much as a proper turbo or supercharger. According to the official specs from one manufacturer of a very similar unit, it's about 5mmHg, or roughly 2psi. But that's static pressure--if you plug up the outlet and stick a pressure gauge on it. Personally I think 2psi is a crock of shit, there's no way such a small motor would be able to shove 2psi at the nearly 300cfm our 1.9l engines suck...the question is how much less.
And lest I sound like an idiot for wanting to try this, rest assured I don't actually expect any increase in power whatsoever. You'd have to spin an impeller like that one at about 150000 rpm to get enough boost to be useful. They do actually make axial superchargers that work quite well though. They're built more like the compressor stage of a gas turbine; the one I looked at had six stages to it and could do 14psi with ease. One rotor with no stator....well that remains to be seen.

All the air it blows will just turn around and come back out the intake. A turbo forces the air into a confined space and thus increases the pressure because the only exit is into the cylinders. wall.---- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 16, 2002 1:41 PM Subject: Re: [SPOC] Anyone seen anything like this?? > Don't forget that unless you are using a blow off valve you could damage your motor so be sure to get the electronic BOV to match the electronic turbo ;) > > If anyone takes this seriously they should be hit with a very large and painful object > I'd like to know if the small boost level does work, keep us updated. > Jonathan Faught > > > Visit SPOC National at http://www.spocnational.org > > Don't forget to update your Profile in the Owners Database. > > To unsubscribe from the list at any time, send an e-mail to [EMAIL PROTECTED] with any subject, and in the message text, "Unsubscribe spoc". > Visit SPOC National at http://www.spocnational.org Don't forget to update your Profile in the Owners Database.
