I hope that wasn't too tech-y for anyone. Cottage Grove 1994 CHEVROLET W4 Box Truck. The output limit is only reached by meeting or exceeding the operating parameters of the unit (point of diminishing returns, speed rating of internal bearings, etc.) A centrifugal supercharger will behave similar to a turbo, with no turbo lag or nowhere near the heat concerns (There is also a major difference in heat between oil fed and self-contained centrifugal compressors.oil fed being vastly more efficient, but that is another thread entirely). TrueCar has 17 used Saturn Sky Red Line models for sale nationwide, including a Saturn Sky Red Line. With a centrifugal compressor the boost curve is linear, so the faster you turn the unit, the more boost it will generate. In contrast, the centrifugal supercharger (Vortech for example) behaves nearly opposite of the positive displacement. Saturn Redline Rear Diffuser Bumper mounting hardware and instructions optional IMPORTANT: Diffusers are mounted to the bumper and the trunk tub. In addition, positive displacement units have more internal moving parts, and therefore take more power to turn and generate more heat. One recent post said it was easier to separate the two halves of the pump first and pull each half out separately (and vice versa when installing the new one). You make max boost off the line, but the boost curve is always opposite of a vehicle's natural power band. The official way is to remove the turbo, but others have commented that it is possible to wrangle the pump out without removing it - though very difficult. Basically, when you get to a certain engine rpm, the compressor will taper off as the engine becomes able to utilize more and more cfm as the rpm increases.

Once the compressor has reached its volumetric capacity, it can no longer produce any additional volume (make more boost/push any more air). The current page gives you an overview of all the pictures available about the 2004 Saturn ION Redline. While at cruise doing 75, I measure about 6 inHg. Under load while accelerating quickly (onto the highway) I top it out around 14 PSI. This is why positive displacement compressors are sometimes rated by their displacement. This is a topic Ive been meaning to broach sine I put my boost gauge in. The positive displacement, which is the style that is on the ION Redline, can only produce a set amount of boost, specifically determined by the size of the housing. The two major types are a positive displacement supercharger and a centrifugal supercharger. The thing is, you have to realize there are more than one kind of supercharger.
