fyi, direct injection gasoline thread:

so better to use the hot exhaust gas directly on a turbine wheel, no? a-la power recovery turbine http://ecomodder.com/forum/showthrea...tml#post204535

as far as I know adding a heat exchanger will at most equalize the heat between the flows, vs using the exhaust directly. If hot is good, hotter is better.
