Wow! Thanks for the explanations guys. That is so interesting how it uses exhaust gases to spin the turbines which then forces more air into engine. It actually sounds like a pretty efficient design. Any reason why turbos aren't used in more vehicles? Because the 850 Turbo engine is basically the same as the N/A engine in the regular Volvos right? I mean, I understand that it has beefier innards to handle the extra power, but it's amazing how a turbine can cause so much more power. Like 168hp as compared to 222hp, or 237hp if you include the T5-R.
Since the turbins spin at such a high RPM I'm guessing there is a massive amount of heat that is created. How does the intercooler work? From what I understand it's a device right before the throttle body so it cools the hot air that is made by the turbocharger, and colder/denser air basically means more HP. So in essense it's a cold air intake system.
One other thing; If I were to get an aftermarket ECU such as the IPD chip, would the computer make the wastegate let in more vaccuum and exhaust gases into the turbocharger thus making the extra 40 or 50hp that the chip gives? Would this be deterimental to the turbocharger since it wasn't build to sustain higher HP loads than 222hp or 237hp? Sorry for all the questions, but I find this fascinating!
