to ricochet...'pieces of crap' ?!?! that hurts my heart. were all on the same team here. maybe if im not a dumbass well find out saturday.

A Supercharger is belt driven, running off a belt. The belt drives the turbine that compresses this air to create boost. This, oh course, creates parasidic HP loss on a motor, similier to the way A/C and Power Steering creat paracidic hp loss. The difference, of course, is the paracidic loss is channeled to create forced air induction, or boost. A Supercharger usually runs at around 4.5 psi on a Honda, so of them are umwaprds of 6psi with a "upgrades." But yes, Superchargers on Honda's tend to run at low boost. Since they are belt driven, you get instant response, since boost starts to build and is available the moment the belt starts to turn. This is unlike a turbo where it has to wait for the exhaust pressure to spin the turbine fast enough to create boost. However, a Turbo has no paracidic loss. It does not draw power or energy away from belts or the motor to do it's job of creating boost. This, of course, means it doesn't rob some HP from the motor to do it's job of creating extra HP, the way a belt driven supercharger would. I turbo uses waste, exhaust gases that realy have one use otherwise, and turn them into something usful to create extra HP. The only downside is, like I said above, you have to wait for the exhaust gases to build enough pressure to spin the turbine in the turbo fast enough so that the air is compressed and boost is created. Especially at low boost, it's trade off's. What are you willing to trade off for something esle. I am not a far of superchargers. I don't like the Paradic loss. At High boost levels, a turbo is more more efficent and reliable. At Low boost levels, the resulting turbo lag is not enough in my view to make me opt for the parasidic loss that results from a supercharger, despite the fact there is no lag and boost is near instant. They are basically 2 oppisite principles to arrive at the same conculsion...Forced Air Induction (Though like I said, this is generally for low boost, for High boost, a supercharger is generally not an option, espically a reliable one. Also, turbo designs are much more effiecent now days than most supercharger designs. This will usually eqaul more bang for your buck, or more output basically).
