vtodd82 Posted December 22, 2004 Report Share Posted December 22, 2004 http://cgi.ebay.com/ebaymotors/ws/eBayISAP...ssPageName=WD1V 5psi huh, probably a gimic. too good to be true things i suspect. anybody have any insight. Link to comment Share on other sites More sharing options...

BigTsBadSS Posted December 22, 2004 Report Share Posted December 22, 2004 I thought the Bazo B4s didnt come in 22s <{POST_SNAPBACK}> Do you guys think that thing really works cause for the price that thin is worh it. Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted December 22, 2004 Report Share Posted December 22, 2004 I hope you guys are kidding... Ok. Superchargers work because they compress the air. What is shown in that ad is not a compressor, it's a blower motor. Think about a hair dryer. What's it do? Move air faster. Does it compress? No way. 30-40 hp? Superchargers are capable of 130-150% hp, not 110%. Best line of the ad: "This is better than nitrous with no effects on the motor in any way" Well, at least everything after the 'with' is true. This is just some guy looking for suckers. Link to comment Share on other sites More sharing options...
SSUPERSSPORT Posted December 22, 2004 Report Share Posted December 22, 2004 Looks like a fan motor and housing from an old gas furnace! Link to comment Share on other sites More sharing options...
SSBeaumont Posted December 22, 2004 Report Share Posted December 22, 2004 Good observation those FANS are used in car applications you can order them from a pep boys. The application escapes me right now. DO NOT BUY ! IT IS A GIMMICK! You will not get anything out of it other than a lighter wallet. Link to comment Share on other sites More sharing options...
zippy Posted December 22, 2004 Report Share Posted December 22, 2004 i like how it's not even hooked up in the picture. Link to comment Share on other sites More sharing options...
styleandspeed Posted December 22, 2004 Report Share Posted December 22, 2004 I have actually seen one that works before that some engineering students here at Texas A&M made. They used an eaton M90 with 3 electric motors off of starters, and could only get 4 psi on a v8, co I don't think that thing will produce 5psi. Just my guess though Link to comment Share on other sites More sharing options...

dcairns Posted December 22, 2004 Report Share Posted December 22, 2004 Just think about how much horse power a supercharger consumes under full boost, (something like 40-50 HP if I recall). Now think of an electric moter than has that much HP, and the alternator/batteries needed to feed it! Also, as mentioned, a fan is not the ideal way to compress air. A fan can compress air, but not as much or as efficiently as other proven methods. Thosee ebay electric superchargers probably get in the way of airflow more than they can help it Link to comment Share on other sites More sharing options...

The pressure increase (boost) is created by a backup of the air trying to move into the chamber. Turbochargers on the other hand compress air. On a turbocharger, the air is exposed to centrifugal force compressing the air as it spins through blades and slammed against the shell of the compressor. Then it is delivered to the engine. That's one reason why turbos are more efficient. Basically, a supercharger is a blower mechanically driven by the engine. It delivers more air than the engine can handle creating boost and forcing more air into the chamber. A supercharger is a blower... Link to comment Share on other sites More sharing options...
Dylan06SS Posted December 22, 2004 Report Share Posted December 22, 2004 Once installed, locate an area near the drivers seat to hit the switch and go. This is better than nitrous with no effects on the motor in any way. No effect on the motor.... yup.... sounds about right! Link to comment Share on other sites More sharing options...
JimJenson Posted December 22, 2004 Report Share Posted December 22, 2004 with that tiny airfilter, and plastic housing, you can bet it moves a lot of air! it will be interesting to see what feedback the seller gets after a few of these are sold and installed.

The only difference between a cent. sc and a turbo is the drive side (sc has a belt driven compressor, turbo has a turbine driven compressor). Twin screw super chargers have specially designed "screws" that compress the air as it pushes it into the manifold portion (see Whipple's explaination). Roots style blowers (a la Eaton -> Magnacharger) have "positive displacement pumps" (read: rotors that seal against one another and compress the air as it is pushed into the manifold) that "increase air pressure and density in the intake manifold" (see Magnacharger's site)-- aka compress the air . A supercharger is a compressor, plain and simple... Boost is a measure of air pressure in the intake manifold. I guess with a tightly sealed fan you might have a very poor efficiency compressor, but ask your self this: If it is a viable technology for compression, why doesn't anyone in any industry use it for compression?

jboyd2004 Posted December 22, 2004 Report Share Posted December 22, 2004 "You'll notice the Roots design is referred to as a blower, while a centrifugal supercharger or the pumping side of a turbo is referred to as a compressor. The reason is simple. A Roots blower doesn't actually compress air, it simply picks it up and moves it." --- Operational Principle of a Roots style supercharger The whipple is a different set up. It does output compress air. The roots design doesn't in the supercharger itself. Link to comment Share on other sites More sharing options...
