English term or phrase: pre-turbine housing
Matt has asked, I'm curious about this one, map drops at high rpm with a factory small turbo due to exhaust pressure. Is it exhaust back pressure or the compressor running out of flow? Okay, so normally what that is caused by is the small exhaust side of the turbocharger.

And what happens, if we're looking at the exhaust manifold back pressure, so the pressure measured pre-turbine housing, with a factory turbocharger, it's not uncommon to see that reach somewhere as high as perhaps double boost pressure. That means is if we've got 15 psi of boost pressure in the inlet manifold, we can easily see 30 psi, sometimes more, in the exhaust manifold. That boost pressure, sorry, that exhaust manifold pressure tends to ramp up as the engine speed increases, as the turbocharger becomes more and more restrictive. And what happens is the exhaust manifold pressure overcomes the wastegate and kind of forces it open. So that's one of the reasons we sort of tend to see that boost pressure drop off.
