^^ [sigh] we were really talking knock and low octane maps, but what the heck. 
I only wrapped my DP to eliminate rattles and to keep the heat off the oilpan.

I get it now, pressure doesnt flow from low to high pressure - high temp is proportional to psi

It does keep heat off the oil pan, also transfer area

however the fact of the matter is though that automotive turbochargers are a very complicated system. since it has a compressor on the other side it's not necessarily the case that the more heat that goes into driving hte turbine the better the overall unit works. HALF of it works better, the other half suffers due to preheated expansion etc etc. you also suck in more hot air when you allow the heat to escape through the downpipe. all these things cannot be ignored and while it's totally proper to discuss such nuances in the engineering parameters you're effectively screwed if you do... screwed if you don't.
