Mike-e Posted July 30, 2007 Share Posted July 30, 2007 ^apparently chart is for iron/something so wouldnt put much faith in it impressive none the less. yet doesnt stack up to wikipedia Aluminium — Melting Point: 933.47 K (660.32 °C, 1220.58 °F) (and that something is either wrong or that motor runs fucking hot and should have heat wrap)? dunno about that. heat wrap keeps heat in the exhaust and out of the engine bay. id say heat wrap would make it worse. i've heard of those turbo exhaust housing bags causing housings to crack also seen many pics of well thought out engines running very red hot.... but think all pics have been on a engine dyno though. example Quote Link to comment Share on other sites More sharing options...
peteretep Posted July 30, 2007 Share Posted July 30, 2007 Exhausts arent made of aluminium though, the rear housing would be cast iron with nickel in it and the rest would be stainless? Quote Link to comment Share on other sites More sharing options...
Mike-e Posted July 30, 2007 Share Posted July 30, 2007 fully. but still, aluminium compressor housing so close to heat source. spose the inlet charge cools it down narm though Quote Link to comment Share on other sites More sharing options...

nismo.capri Posted August 2, 2007 Share Posted August 2, 2007 fully. but still, aluminium compressor housing so close to heat source. spose the inlet charge cools it down narm though The air is passing through the compressor so fast it doesn't really have a chance to heat up that much. The inlet air gets heated becasuse it's getting compressed (PV = nRT and all that) Quote Link to comment Share on other sites More sharing options...
