Electronic Turbo Options

Is this a good buy? or crap?

wow lots of mis-information.

A) a turbo system is baised on a turbine, not necessarily exhaust pressure, although "turbo" when talking about vehicles ARE based on exhaust pressure, there are plenty of other non automotive applications where turbos are run off of electric, belt, phneumatic, or hydrolic power sources.

B) The reason an automotive electric turbo charger wont work is because of the speed the turbine needs to spin to produce a pressurized area. actual exhaust driven turbos can spin in excess of 60K RPM, these 12V driven turbines produce no more than 10K RPM at best (i dont remember the exact #s but the difference is HUGE), theres no way they can spin at a high enough rotational velocity to produce the pressure needed to provide any decent ammount of forced induction. which is pretty much exactly what kamix and uppity's posts were saying.

C) A turbo most certainly does not block exhaust gases. what happens is when there is too much build up of exhaust pressure in the exhaust side of the turbine, the wastegate will open and allow the gases to bypass the turbo system completely and either dump it into the atmosphere or right into your exhaust pipe (the ones that dump it into the atmosphere are not DOT legal for emission reasons). also turbo systems enjoy a bit of back pressure, this is due to the fact that to spool up the exhaust turbine, it isnt the exhaust gas actually flowing through the turbine that spools the turbo, it is in fact the exhaust gases expanding from heat that causes the wheel to spool, so if the exhaust gases are in the turbine for a little longer, it allows them to expand a bit more and spool the turbo quicker than if it was completely 100% free flowing.
