[DeTomaso] ZF polish question.

[Charles Engles]

Dear Tony and Michael,


             I, too, have heard that a porous cast iron block or alumunium
manifold or transmission case will transfer more heat than a polished one.
This conversation prompted me to ask an expert in the field. 


             He is says that it is absolutely true that there is less heat
transfer with a polished surface than an unfinished cast surface, BUT the
effect is insignificant.   It is tangible, but at extremely small levels.   


            The take home lesson for lovers of bling is to polish away!
Remember what the ancient Greeks said, "All things in moderation including
engine bay bling."


                        Scientifically yours,  Chuck Engles

Running hotter sounds like an urban legend thing.

I have read that the polish process makes the ZF run hotter because the
pores of the cases are closed off, mine is simplimy super duper cleaned by
using Eagle One wheel cleaner that etches, not ordinary wheel cleaner,
followed by Aluminum jelly. If I were going to jazz it up, i love the look
of the black wrinkle finkle with the tops of the ribs in raw silver.
