I'm sorry to all you turbo and supercharger people. i'm not saying that turbochargers are bad, in fact, i'm very impressed by the output they have made on the WRX, Evos, SRT-4(i know dodge is american), and supras, RX-7. but for a 17 y/o pure bread american, turbos just aren't my thing, and don't say that i must not like power and speed, cuz i love power, i love the neck wrenching u get from 318 lbs-tq. I love the feeling of 300 hp under the hood of a car. but i have been grossly misinformed by performance stores, websites, and this site(ref. the shaft of the vortech). i have gone back and done some research into an area where i am already somewhat familiar. Turbochargers are great at higher altitudes and they do have other advantages. but the biggest disadvantage will still being an advantage, is that they use the exhaust. and exhaust creates a termendous amount of heat. and heat is not the friend of an engine. but again, i'm sorry to those i offended. i've been grossly misinformed.



Ignorance is bliss I guess. Others say this is a gutsy post; I say its a cop out.

Your comments about heat and turbochargers are still quite confused. The heat present in the exhaust is there whether you use a turbo or not, its more related to the amount of power output than anything else. A turbo uses the heat and kinetic energy in the exhaust flow (waste energy that normally flows right out the tailpipe) to spin the turbine, transforming the waste energy right back into a useful form. The only additional heat issues related to the turbine side of the turbo is simply the fact that there is more surface area to the exhaust system that you have to be careful of.
On the intake side, many claim that intercoolers are required for turbos because of the added heat from the turbine side of the turbo. This is largely untrue. Very little heat is transferred through the center section of the turbo which is always cooled and lubricated by oil, as well as often cooled by the water from the engine cooling system.
The reason intercoolers are often present in turbocharged engine systems is due to the fact that air heats up as you compress it, no ifs ands or buts about it. The reason intercoolers aren't present on most aftermarket supercharger kits is simply for cost and complexity reasons, certainly not for performance, as a supercharger would benefit just as much from an intercooler as a turbo at the same boost pressure.



Praise Jesus!!!!!

Can I get an AMEN???

Those who cannot remember science classes, anytime you change a molecules state there is energy released, most of the time in the form of heat. This is also true when you compress molecules together. Ever heard of a pressure cooker?
