I have an idea for my car but i dont want to give it away cause I want to be the first to do it so it'll be kinda hard to explain without giving it away, lol
This hole question is about centrifugal superchargers, if that makes a diffrence.....
superchargers are better for bottom end power cause they are belt driven, but my question is why arent they good for top end? to me it makes sence that the higher RPM the motor gets up to the faster the SC spins up and thus creating more boost, so what limits a SC to only botom end power?
I dont know to much about super chargers, just turbos so I have a pretty good idea of how a centrifugal SC works but this one thing has me stumped.
thanks in advance

its the design of the s/c


a centrifugal s/c will not have the low end power that a roots style will have have


the centrifugal is more like a turbo

So a centrifugal one works pretty much like a turbo with very little lag?

no lag on a centrifugal or roots supercharger because it uses engine power, and directly related to engine speed (linear)

the output of a centrifugal blower is like a turbo in that its output is still proportional to the gearing and cfm rating of the unit. blower is less efficient because it is a parasitic drag on the engine, just like your alternator or A/C.

the gear ratio between the input and output of the blower determines at what engine RPM the unit will hit peak output at. usually they have some type of graph that shows output.

14.82 @ 97 mph

actually, ill see 5psi from 2.5k to 5.5k rpms, then at redline or just b4 it it will creep up to 6psi, sometime 6.5 if its cold.....but i have a roots type charger....
