Using the recently updated/corrected expressions cited in the link above, and Rob’s 1700 average horsepower, To=200F, Ti=90F and a run duration of 1.3 minutes, results are a coolant flow of 26 gpm and a reservoir volume of 34 gallons. Seems to be in general agreement with other’s experience.
Also, in line with Blue’s “do your own testing” principle, experience has shown that pump sellers, particularly those that offer pretty, anodized, hot-rod pumps are notorious liars as regards the performance of their pumps. They often can’t flow what is stated even against zero backpressure. Remote reservoirs with possibly long piping runs and fittings are going to have suction and headloss issues.
The latest CAD results look very sleek, but like Rex, I still worry about getting everything tucked inside. Maybe it is bigger than it looks! Hope you carry on the CAD work to include most of the ridiculous amount of stuff that is needed.
Also, a 400 mph run is pretty much a drag race, and the tail doesn’t look too push-truck friendly. How is it going to get off the line? Done any vehicle performance simulation yet? Driveline plans?
