<HTML>Peter,
I will telcon the owner on your square foot question. as he has several non-condensing cars and a lot of factory data. Much like the "buyer beware"
slogan when getting a lot of free info on this wonderful Phorum of John Woodsons
realize that there is a lot of variance of opinions on steam stuff and Stanleys.
i would hate to admit how many perfectly good erasers I have worn out doing mechanical engineering computations!
170F is on the high side but this car went over 20 miles flat out and could burn at a 30HP rate of up to 6 gallons per hour, a lot of stuff was coming back to the water tank at a rapid rate. Also I know a few people who have lost there pump prime, especially with the water tank quite hot and very low water level--one foot of water exerts .43 psi so keep the water from getting too low, especially in a condensing car.
A very good source of all kinds of thermocouple gauges and other equipment is
Omega [
www.omega.com] . They have digital thermocouple meters of very good accuracy starting off at about $79, many are multimeters as well and are cold junction compensated.
Best to you, George</HTML>
