Ok now I’m excited. I didn’t expect that.

Lol my whole 2 acres is a hillside and I fell in love with the wrong house back in 1985. I had an open trailer back then so it wasn’t a big deal. Sorry but I can’t tall you the temps as I forgot to hit the RacePak record button and didn’t look. I had it 175 leaving the lanes to do my burnout so I’ll guess around 180 at the end of my pass and 170 by time I got to my pit spot.

About 30 to 35 years ago, Detroit Diesel built some 6V 92T engines for city buses. The diesel engines were inclined and transverse mounted and rated at 277HP.
These experimental bus engines ran methanol injected through larger injectors. The head castings were modified to retain heat and had provision for the glow plugs from the 5.7l diesel. The one they built from an Olds gas engine. Detroit V engines have their turbo mounted on the scavenging blower which is mounted in the V. There was also a glow plug controller, with LEDs for each cylinder. For initial start they all lit up like the dash glow plug timer indicator. Once started they flashed as they were turned on and off in firing order sequence. In the shop they idled like a top fuel or blown alcohol dragster. When they pulled in from doing a run and it was well warmed up it used like the diesels for about 2 minutes. By then it they would cool off and idle like a dragster again.
The methanol has such high latent heat of vaporization that when injected into the cylinders it just absorbed all the heat of the compression. This necessitated the glow plugs. Medicine Hat, Alberta had three methanol production plants with two closed due to economics at the time. The City of Medicine Hat was interested in getting the other two opened again, thus the transit bus interest. They got two methanol buses with federal government grants. Part of the grants was a stipulation to install monitoring instruments in two diesel buses so operating conditions, economy and emissions could be compared. The methanol buses came with this installed.
Initial engine life on methanol was 50,000 miles. The high volume of fuel required washed the cylinder walls down. Additives were tried and got engine life up to 100,000 miles. The diesels were going 350,000 to 400,000 miles in city bus service which involves a lot of stop and go. Good intention but this experiment did not pan out.
