if I am not mistaken the intake of the supercharger is under vacuum when the supercharger is turning?
Clear, thanks. But as long as there is vacuum, the supercharger is not doing it's job.
Reason why I'm asking: my car isn't tuned properly and it takes an effort to get it to boost. I'm getting more convinced to do something about this.

Ok...newb question.
I am planning on running m112 on stock 99 v6 with a 25%udp to keep boost down. Will i really have a heat issue at the low boost i will be running?
Ok...sorry left out some info.
Eaton has the stock pulley
crank will be the 25% udp
the coating has been removed...guy i got it from was running meth so he removed the protective layer on the eaton.
If i get what your saying is i should be ok for now till i build the engine up down the road.
I thought I had heard people doing a small shot of NO2 on blowers? What is too all know there good/bad. Again thanks for all this info perfect time as I am looking for the near future.
If your looking at nitrous as a cooling agent yes been done over and over but not very cost effective for a street car. You can slap a 50 shot on there to see how it goes but meth is a better bet for sure
For the most part, true. However, the engine is still rotating the pulleys/gears, so some N/A power is being used regardless. Depending on your driving style, it might not be noticeable, but it is not a free lunch. There is additional friction there, boost or no boost.Superchargers 101 - Introduction to Superchargers
And because of the way superchargers work, they provide power only when the engine is under full throttle or under load... not under normal cruising conditions. This means that the supercharger will not affect the engine's reliability, longevity, or fuel economy under normal driving conditions.
You mention it here regarding atmospheric pressure - typically this is expressed as psia (psi atmosphere). A gauge shows psig (psi gauge), which is the boost OVER atmosphere. It is typically accepted that when someone talks about the boost they are making and psi, they are really talking about psig - though it's usually expressed as psi.Supercharger Impeller Boost is created at the point when the supercharger's internal impeller pushes enough air through the blower to overcome the vacuum force naturally created by the engine's air intake, so air is being forced, rather than pulled, into the air intake. Boost is measured in pounds per square inch, or psi. More boost equates to a more dense air charge into the engine's combustion chamber, which allows the engine to burn more air and fuel and create more horsepower. Most street superchargers produce somewhere in the range of 6 to 9 psi, meaning they produce 6 to 9 additional pounds of pressure over the atmospheric pressure at that elevation (at sea level atmospheric pressure is 14.7 psi).
Another concern some people have towards using a supercharger is that they think it will increase the engine's compression to the point that it will cause detonation inside the combustion chamber. Detonation exists when the combustion pressure is raised so high that the inlet charge ignites itself before the spark plug fires.
Vortech, Paxton, and ATI (except ATI's and the new Vortech SL self-contained systems) all use the engine's oil to lubricate the step-up gears and keep heat and friction to a minimum.
Intercoolers and aftercoolers cool the air after it has been discharged from the head unit and before it enters the intake manifold. The cooler air provides a denser air charge which can make added horsepower, especially under higher boost conditions. Intercoolers and aftercoolers, while popular for racing applications, are not normally needed for street drivers running 6 to 9 psi of boost.
