exhaust gases spin turbo compressor and push large amounts of air into cylinders. air makes fuel burn more efficient. Do you want me to elaborate on that?

Basically..but not really. You know that it helps make power, but you site efficiency as the reason. That's not true.

"Air makes fuel burn more efficient"

Should read something like this...

"Increasing the airflow into the cylinders allows/requires the engine to consume a proportionatly higher quantity of fuel."

What YOU said would mean that you don't burn any extra fuel when you pump the extra air from the turbo into the intake. That would cause your engine to run lean.


From what I've read so far in this thread, it sounds like you WANT to know a lot more than your DO know...hence the reason everyone is telling you to do research before asking questions.

Before messing with a turbo of any kind, you should be able to
describe the function AND purpose of and/or define the following without opening another browser window to search... (yes...function and purpose are 2 totally different things).

Oxygen Sensor-especially "wide band" setups (what is it, how does it work, why is it needed)
MAF (what is it, how does it work, and why is it needed)
Stoichiometric
Barometric Pressure
Spark plug temperature
and lots more...

Don't get me wrong, most mechanically inclined people can figure out how to fab up / bolt on a turbo and get more power, but anyone that want's to get seriously into modding an internal combustion engine should have a thorough understanding of what takes place during the combution process.

Thank you for your response, I did read a some of those treads about turbo, to be honest, some of those explanations are too deep into physics, I also saw that sho with 493HP but they used NOS. A little by little of info, that I'm getting from you guys helps no matter what and I do read a lot of info here and trying to research more as I go, but kinda hard to make up my mind. I know the more you modify the less resource you leave for that engine to live longer, so i would like to do both. This Blue SHO that i just bought, after 3 weeks driving it, i want to store it now and use it as weekend baby and I know that in about 5-10 years there will be probably couple of hundred of them left in the whole world.

While Bab and James responses are hillarious, maybe we should ease up. Guy is taking everything fine and listening to what people have to say.

Teach rather than ridicule here, not a troll and he is not asking about DTT

I have A4 but it's not bi-turbo though, I don't even think they make bi-turbo anymore. I like SHO, so that's why I'm interested in modifying it.

If they had a book called Fluid Dynamics For Dummies, I'd have several copies.

oh ya, you'll want to get ThermoDynamics For Dummies also.

All I want, is to stop reading "bi" turbo, it's unsettling for me, I'm just getting over Ians raging tongue at Tonys wedding what like two years ago.
Lets say "twin" turbo from here on out ok

Art5 IMHO do what you want, it keeps it interesting and you seem to be taking it like a man. (pun intended) Just understand that if this forum could collect $20 for every douche that joins and starts wanting to make his $289 SHO have 500hp and is clueless about how and what else needs to happen, Beth could retire. Good luck and baby steps.
