So the question here is when do superchargers start to kick in? When do you start to feel it? Is it at 3500 RPM? 4200 RPM? I realize the difference between roots/twin screw and centrifugal blowers but it seems like the most popular ones are the centrifugal blowers. Please, I really want to know before I invest a lot of money in one. Thanks

Centrifugal are said to kick in a little later. I dont have one so I cant be sure on when. Roots are supposed to kick in right away.

depends on which u buy, vortech and other centrifugals are supposed to kick in a lot later than say a kenne bell, the kenne's are supposed to make boost as low as like 1800 or something i think, also depends on size and what car.

a kenne bell will make a ton of power down low where as a vortech/procharger won't build full boost till around 3k RPMs

Stever

So if a Kenne Bell will build boost at lower RPMs does that hurt your MPG? But then again, if you can afford a KB I guess you're not worried to much about MPG.

Hells yes. It will definetly affect your MPG. Throttle + low-end Boost = Less gas-milage.

know that even with my centrifugal blower I am still making more power right around 2800 RPM now than I was at any point in the power band before.

Stever

Great!! That's just what I wanted to know! Because I don't want to invest a lot of money into a blower and have it only put out something around 4200RPM. What's the use in that?

my vortech seems to kick from 3-5 grand, more the higher it gets. i havent redlined it or anything yet, but at lower rpms the throttle response is quicker and its still notticeably faster. i love how i dont melt my tires with it, id go with a centri for a daily driver.

Hey Stever...
The only experience I have with hairdryers was a Roots style 300 cfm Sebring that I had on a 1.8l MX-5. It didn't have the "turbo" lag of the centrifugal types, which I liked. It really felt like a v-8...a continuous powerband, if you will. I am assuming that it would be the same feeling on the V-8s. If you can afford it, I'de spring for a Roots. But, hell, ANY blower would rock!
BTW, I beat the hell out of it b-4 and after the supercharger. I got 30 MPG no matter what I did. Someone with one on a Stang could prolly let you know how it affects their MPG.
Good luck,
Troy
