Specifically, I want to understand more about wastegates and turbocharging vs turbo normalizing. This may turn into a lot of questions over; what I *think* I know is bound to be not entirely correct and impacts of things like compression ratios and compression testing are bound to come up. Bear with, I’m ignorant, not stupid.
As a starting point for me, I read this article https://www.avweb.com/ownership/mot...nd read that,that could grow cracks overnight.
From it I gleaned the manual wastegate adds another pilot control in the equation that allows the pilot to manually tune the boost to achieve given manifold pressure; basically a fourth knob. Is that a correct understanding?
Then, there’s the automatic wastegate. This system essentially regulates the exhaust flow (in a variety of ways) to effectively maintain a predetermined manifold pressure.
Those two dump exhaust before hitting it hits the turbo.
Finally, there’s the Continental system that doesn’t care about exhaust flow before the turbo and instead dumps excess boost after the turbo and before the intake.
Is that essentially correct?
Second, how does the wastegate system work in a TN setup? Is it just an automatic wastegate that’s set maintain 29” of manifold pressure until you climb high enough it can’t anymore or is it some other rube goldberg contraption the regulates the magic smoke flow?
