**Fan Railer**Lets look at actual numbers here, guys.

Page 63 of this sheet shows the 3512C HD engine (with similar rating to the one installed in the ALP-45DP) pulling about 102 gallons per hour at rated load (1800 rpm & 2200 hp). So two of them together pull around 205 gallons at rated load (1800 rpm & 4200 hp).

Compare this to a 16 cylinder 645, which pulls around 170 gph at 900 rpm (3000 hp),a 12 cylinder 710, which pulls around 150-160 gph at 900 rpm (3200 hp), and a 16 cylinder 710, which I read pulls around 190 gallons per hour at 900 rpm (4300 hp).

And to clarify, low speed diesels are below 200 rpm. Medium speed is from 200 rpm to 1000 rpm. High speed is anything above that.
