or an electronic single used to prevent down time? niether of these are superchargers or turbocharges. supercharges and turbochargers can be classified very easily, simply check how the device is being powerd.

hybridsol,
take it from another mechanical engineer, conical is a word, it refers to shape. Example, an ice cream cone is conical, so in a snail shell...... No stress buddy, just letting you know

Lots of Turbo talk...
Ok folks.. I've seen a lot of terms being slung around 'bout turbos.. how's about an explaination for those not in the know? Sounds good, huh?
(all terms basic; not technicly defined) "Turbocharger, turbo": Exhaust-driven forced induction. Generally, hot, already-burned exhaust gas builds up in a chamber, creating pressure (charge) that eventually allows for a "re-burn" of that exhaust gas in addition to the new fuel/air mixture. Power from the "back end" of the engine. More power, and when done correctly, less harmful exhaust gasses. "Twin-turbo": 2 identical turbos. (Twins are identical, yes?) A twin turbo usually uses 1 tubo for each bank of cylinders. That VW 16 cylinder, 4 turbo? "Quad Turbo": 4 turbos, one for each bank of 4 cylinders. Exhaust from each bank of cylinders feeds a separate turbo. "Bi-Turbo, biturbo": Usually Audi specific, but this is the little turbo/big turbo setup ("Bi" = two, for those of you who haven't surfed enough porn lately...) As others have commented, this is a setup that tries to eliminate the problems with a big turbo (lag) and a small turbo (power). Note: RX-7 Gen III's were listed as twins, I think. They are actually "Biiturbo" or at least sequential. "Sequential Turbo" Inline turbos. 2 turbos, usually of differing sizes, arranged much like the Audi "Bi-turbo," but they are occasionally the same size. Note: generally, the correct usage of this term implies that the exhaust gasses from both sides of the engine (or all exhaust ports on a radial) combine before entrance to the chamber, as opposed to the twin setup above. This is a "larger term" than "bi-turbo;" a bi-turbo is sequential, but a sequential turbo is not always a bi-turbo. The problem here is one of terminology. People throw around terms 'cuz they sound cool, not because they are real; and manufacturers and magazines are just as guilty as the dude two houses down who doesn't know a turbo from a water pump. (For example: yeah, I know that not all twins are identical, but the colloquial meaning describes identical objects.) Superchargers? Damn if I know beyond the power comes from the "front end" of the engine: air is sucked into the supercharger, then blown (hence "blower") into the combustion chamber, creating more pressure and more powerful burns. Basicly the same effect as a turbo, but superchargers require a "vaccum cleaner" to suck in the air, creating parasitic drag (like your air conditioner), and the clean-air benefits are not there (beyond the basic more power/less cylinders advantage). Feel free to correct me if I'm wrong... Spart :jump:

who loves god? why do you even need to get religion involved in a forum that we should talk about car's now even though your post is focusing on the main topic, but yet it is off therefore i would advise you to post in the off-topc forum,hehe.:bandit:
