Hey guys....sorry to make you dish out more turbo info but I already read the turbo threads and know a lot about turbos and still have just a few intelligent questions to ask so please bare with me as I search for answers!
OK...lets start...Lets say I wanna run 6 PSI from the tubro into my A20A. I have (pretend) a Garret T3 which I ASSUME can pump out more than 6 PSI. How do I control how much pressure comes from the turbo.
Is it the wastegate or the BOV?
Here is what I ASSUME.
The BOV is vaccuum controlled and only lets air out of the INTAKE SIDE when you take your foot off the gas to prevent the intake charge from slamming into the butterfly and going back through the intake pipe back into the compressor? YES?NO?
The Wastegate is what allows the exhaust gas to flow AROUND the turbine to regulate pressure from the turbo (regulate turbine RPM's). YES?NO?
How do you adjust the wastegate....say one day I wanna run 6 psi but I have forged internals and some kid wants to race me....can I jump out at a red light with a wrench and a screw driver and adjust the wastegate for more boost?
How do you know where to start with the wastegate? How do I know I'm not going to install a used turbo and first thing it does it try and pump out a million pounds of boost? Do you start at zero and work your way up to the desired boost?
This is all for now...after this I need to know about a small amt. about ignition control and fuel control and then I will know how to turbo my A20. I can do the rest on my own...just a few more questions though. Hpoefully I can get some answers!
