Douglas,
I'm not an engineer either but I'm obviously a dummy for starting all =
this and will think twice before doing it again.
It's not my idea by the way, a guy gave a talk at our local Triumph car =
club meeting about 12 months ago. I, also was sceptical and it took me a =
couple of days to understand (at least I thought I understood) what he =
was getting at and made one the following weekend. It's been on my car =
since then.=20
I put it forward because it's interesting stuff and I like tinkering =
with such things.
Trevor Boisey may be right; maybe it doesn't work the way I think it =
does, but that's the way it was explained to me and it does work! The =
radiator does not get used in normal driving. This system is apparently =
on some production cars.

Bob,
I'm not a mechanical engineer, but hopefully am no dummy either, and
have been building English car and bike engines for 22 years (some for
racing).
I would need to actually put thermometers in a few places and do some
testing, but I think what you are advocating could make sense.
Clearly the head is the hottest part (and a relatively small part as far
as heat dissipation area compared to the block). Also our cast iron
British engines are not dissipating heat evenly. An inline 6 (like the
TR6) block has considerable surface area to use.
I do have to question your premise regarding the cooling effect of the
incoming mixture (it gets pretty well cooked once you put it to a 9 to 1
compression and then explode it). It also should have the greatest
effect on the pistons and head (two of the hottest pieces in the
engine).
I finish off my summer sessions this week, and then go on jury duty
(yes, I know), but hopefully will report back with some thermometer
readings that may support your proposal.
Regardless, I have found your proposal very interesting (enough so to
put off some work I should be doing to satisfy my curiosity regarding
your modification). I'm also the guy who spent most of my free time for
a week trying to develop a "radiator" for my air compressor, so I guess
it could undercut the credibility of my opinions. I guess I have a
problem with machines and "heat."
Thank you for your contribution.
