At first glance it looked very promising with their thermal
barrier coatings but on closer inspection their graphs of
power improvement don't look very spectacular at all; in
fact the one graph actually shows power losses for all rpms
except @4000 and 8000rpm which is not exactly diesel
operating regions.
I used this stuff on mine and Dad's pistons. It was in Dad's
old head's chambers. Interestingly this one runs better.
Doubt it made the difference.
I did a little "test" with the stuff on a piston. You know how
a small propane torch will make metal wet with condensation
and then it flashes off as it heats up? I took a coated piston up
to the shop after it'd been sitting in the house. Weather was cold
so it was below room temp burt not cold nor warm to speak of.
I fired up the Bernz-o-matic and pointed it on the piston top. It
made a pencil sized spot of dry with condensation around it after
a few seconds. I kept at it and managed to make the dry spot
about twice as big but couldn't get it to flash off. In fact, when I
finally quit, I'd managed to fill the depressions in the piston with
water and still couldn't get much to flash off! It indeed either
reflects or disperses the hot spots! I believe the CBC-2 is
supposed to reflect.
I'd have done the new combustion chambers but I wanted to get it
together and also didn't want to mask off the new head and load it
up in the little blast cabinet plus pop and reinstall the prechamber
inserts.
