I replaced the header and the intake in my Midget and had them both ceramic
coated. I also replaced the rest of the exhaust at the same
time.http://www3.sympatico.ca/robertduquette/temp/Intake009.jpgPrior to those
changes the Midget would stumble away embarrassing from an intersection after
a prolonged stop at a red light on a hot day and run rough until ( I think )
the air would start to circulate under the bonnet.Afterwards it provided a
respectable exit.
So, this is a fairly subjective unmeasurable result as the coating wasn't the
only thing done, and obviously the exhaust had issues to begin with.
My 100 doesn't have overheating issues. I was thinking that the louvered
bonnet may have something to do with that.Robert DuquetteOttawa ON Canada
