at 500rpm's, at7500 rpm's etc. A turbo only kicks in around 3000 rpm's. I'd just like to know what the advantages are to a turbo, I hear they are a lot of work and have a lot of little stuff go wrong compared to a s/c, but i don't know much about turbo's so can u tell me why this is good?
Not exactly. A blowers boost, especially centrifugal, depends on engine RPM. A turbo, will be able to attain full boost all throught he RPM range...as long as the exhaust volume is enough. Also the supercharger uses alot of engine power to drive it, while the Turbo just adds a little backpressure to the exhaust.
The Vortech for the Duratec only reaches its max boost (9 psi) at redline, and only starts building boost around 2500-3000 rpm. I get 1 psi at 2500, 3 psi at about 4000, 5 psi at about 5000, 7 psi at about 6000, and full boost at redline. A turbo should create more boost at lower rpms.
