ive been having a discussion on another board about heat and how it affects the flow of a turbocharger.

someone stated that the exhaust gases will drive a turbo charger at the same exact rate on a manifold mounted turbo vs a rear exhaust mounted turbo.

my claim was that the exhaust gases will lose velocity due to transfer of heat through the metal in the exhaust system. and if exhaust gases are colder they dont move as fast. and with less velocity and the same mass, the exhaust gas now has less momentum to push the turbocharger. his argument to this was the the air would be more dense and have the same effect. and that the heat loss is pretty much insignificant.

what do u all think. please explain in detail please.
