I edited the page to replace the unit L/m with L/mn (because 'm' means meter and 'mn' means minute). CyberBoris

In what way is this notable if it hasn't yet happened?Malick78 16:53, 9 September 2007 (UTC)[reply]

Is the project even realistic ? They seem like a bunch of unfunded no-hopers using obsolete technlology. It's going to take much more than the combined funds of a bunch of garden shed amateurs to break the record. —Preceding unsigned comment added by 116.30.13.168 (talk) 11:38, 9 December 2010 (UTC)[reply]

What a wonderful and pleasant individual you sound to be. I'm sure the summation of your life's acheivments puts these fellows or 'garden shed amateurs' to shame. Obnoxious thicko. 92.25.115.193 (talk) 00:08, 21 July 2011 (UTC)[reply]

Horsepower or Thrust?

From the article:

Thrust:

Stock Engine for low speed testing: 42,500 hp (31.7 MW)
Specially Enhanced Engine for record: 52,000 hp (52,700 metric horsepower)

The problem here is horsepower is a measure of power while thrust is a measure of force. This comes from the project's website though, so we may be stuck with it. Nibios (talk) 13:14, 4 October 2012 (UTC)[reply]

The LM1500 is also the name of the static gas turbine engine used for things like gas pipeline pumps. The calculation of horsepower from thrust and speed is simple, thrust in pounds x speed in feet per minute / 33000 pounds.feet/minute. The highest power J79 in service is the Israeli built GE-J79-J1E which achieves 18,750 pounds of thrust with afterburner. ^[1] Let us assume NAE has one of those Israeli engines, but has super technicians who have breathed on it and achieved a little more, 20,000 lb.st for ease of calculation. At the current highest speed, 477 mph, which nearly resulted in the loss of Jessi Combs^[2], the putative 20,000 pound thrust engine was moving at 41976 feet per minute. 41976 x 20,000 / 33,000 = 25,440hp. They would need to reach over 900mph to achieve their claimed power of 52,000hp. The only honest way to rate a jet engine is by thrust, power depends on speed achieved, as such the misleading claim does not belong in this article. I wonder if the team would be interested in stating the thrust of their race engine? Chann94501 (talk) 19:02, 21 November 2017 (UTC)[reply]

What is a "(52,700 metric horsepower)". Is it related to the metric foot and the metric pound? Tuntable (talk) 07:28, 26 January 2021 (UTC)[reply]

by whom tag

"has carried out the required[by whom?] systems integration" I read this as a fancy way to say "we built wheels and adapted the steering to the wheels instead of the control surfaces" which in engineer speak is "carried out the required systems integration" Required is as such not in the "by law" sense but in the "necessary because it was a plane and is now a car" sense. I am removing that tag now. 176.11.135.164 (talk) 08:20, 5 October 2019 (UTC)[reply]

No s**t Sherlock

"The vehicle failing to stop has been suggested as a factor in the crash of the North American Eagle in an August 2019 land-speed record run.[7]"

I kinda know what it means to say but it sounds daft. It's a bit like saying "Water flooding into the Titanic has been suggested as a cause of it sinking". Totally true, but totally unhelpful.

Should it say something like "Failure of the braking systems has been suggested as a cause of the fatal crash in August 2019." Assuming that is what the reference says of course. Otherwise just remove it. 46.227.49.108 (talk) 14:37, 7 November 2019 (UTC)[reply]

Four wheels or five?

I must be missing something here. Dozens of sources call Combs the fastest woman on four wheels but the vehicle appears to have five wheels. Did some searching but can't find details of the vehicles running gear. - Samf4u (talk) 13:44, 25 June 2020 (UTC)[reply]
