I am creating a new thread for Ben's Vanderbilt Cup Racer and merging this new thread with the original thread to see if this will get page one to open correctly. I have found that merging a new thread into an old thread puts the new thread's messages at the top.

If one hasn't already, this is well worth reading.


Here is a quote from F.E. Stanley in it:

"The body is 16 feet long and 3 feet wide at the widest
part. It is pointed in front, and terminates at the rear in
a circle with 8 in. radius, tapering to 3 foot width and
to the point in front with cycloidal curves, or curves
with constantly diminishing radius. The bottom of the
car is perfectly straight and smooth. It has a clearance
of 10 1/2 in. The sides are vertical to a height of 18 inches,
and from that line the removable top is oval, curving
both transversely and longitudinally. The largest cross
section, including the wheels, amounts to 9 square
feetÖ The total weight of the machine was 1,675
pounds. The boiler weighed 525 pounds, engine 185,
burner and firebox 75, pumps, tanks, etc., 50 pounds,
making the total power plant 835 pounds, or less than
half the total weight of the machine."

The more I think of it they may have just used the low water alarm they used in 1902 to 1906
They may have also used a stand pipe like used on the condensing cars for a surface blow. They could have had it set for the high water level for steam up.
After the last Tour I was on maybe some of the guys that scorched there boilers should add the low water alarm , back in use.

Iím not very good at explaining things all the time.
In a steam engine the pressure pushes the piston down the cylinder till the valve closes. Itís a pressure engine to this point. Then there is anywhere between 12 to 15 present of piston travel before the valve opens to exhaust. Depending on the valve design.
Steam expanses in volume as it cools. You have to go by the steam tables for the rate of expansion at the different temperatures, this is the real reason you superheat. After you play with numbers long enough you will come to the conclusion you gain nothing going over 200F over saturated temperature for superheat.
In a compound or triple you look for 25 to 30 percent expansion if you can get it. Not many do.
Yes I started off running 1000 psi at 1000F with my Derr boiler in my 1920. It didnít seem necessary and I dropped back to 600psi at 700 F using Mobil one 634 gear oil ISO 460. You cannot see it in the winker. Brent C used a die in oil in his car with the same stuff to see it in the winker.
