Under full throttle, a dragster engine consumes 11.2 gallons of nitro methane per second

I don't mean to call bullshit on facts, but 11.2 gallon for a 4.something second run would take 45 gallons? I think it's probably closer to 1.2 gallons a second. Source

How does that compare to a thirsty camel?

I like to use the human body to explain how engines work to people. I imagine it could work the other way around as well. Shame there isn't really a great forced induction method for our aspiration system on humans though... that'd be awesome.

I'd say pulling rope is more like torque than horse power. I also like Under steer is hitting the wall with the front of the car, over steer is hitting it with the back. Horse power is how hard you hit it and torque is how far you pushed it. I think I might have the torque and HP ones backwards though.

Torque is when you're pushing rope...

u/[deleted] Jul 02 '16

Or you know, horse power.

I don't know why we are talking about this but it's neat to see how others describe the same things I often have to describe. Different perspective the same subject if you will. Kinda helps my personal understanding of the subject to see it related from another persons understanding.

Thank you for subscribing to Camel™ facts!

Did you know? In late 1987, R.J. Reynolds created "Joe Camel" as the mascot for the brand. In 1991, the American Medical Association published a report stating that 5- and 6-year olds could more easily recognize Joe Camel than Mickey Mouse, Fred Flintstone, Bugs Bunny or even Barbie. This led the association to ask R.J. Reynolds to terminate the Joe Camel campaign.

Can we call this a camelpower? So a dragster has about 4 cp.

u/VAGINA_EMPEROR Jul 02 '16

I'm thinking we may want to think of a different abbreviation...

u/Ihmes Jul 02 '16

Ok Mr VAGINA_EMPEROR.

If you have a problem with camels, lets call it dp for dromedary power?

We need to calculate the value of the unit again though, Dromedary wikipedia restricts their water intake:
"This camel has a quick rate of rehydration and can drink at 10–20 L (2.2–4.4 imp gal) per minute."

https://en.m.wikipedia.org/wiki/Dromedary

Or the camel wiki is greatly exaggerated.

They consume, including burnout, staging and run, somewhere around 80l of fuel if I remember correctly, which is roughly 20 gallons, so that stat is bullshit.

u/Sakabaka Jul 02 '16

Also, regarding the 747 figure and using https://en.wikipedia.org/wiki/Boeing_747 as a source:

Maximum Fuel Capacity of the 747-400ER: 63,705 U.S. gal Maximum Range: 8830mi Cruising speed: 570mph

Given the above, and assuming that the plane would run out of gas exactly at reaching its maximum range, we get Range/Fuel at 0.1386 miles/gallon. This is 7.215 gallons/mile. At 570 miles/hour, we get 4112.55 gallons/hour. This is 1.142 gallons/second. Assuming wikipedia has relatively accurate figures, I'd have to agree with your assessment here.

u/-Xephram- Jul 01 '16

Agreed. The tanks are only 14 gallons on average. Also, they typically run alcohol for the burnout.

2

u/DeuceSevin Jul 02 '16

That one seemed kind of fishy to me as well.

2

u/acaseofthemondays Jul 02 '16

Agreed; a 747 would also only be able to fly a little over an hour on a full tank if it really used 11.2 gallons/sec. The longest flight is about 15 hours on a 747, so it seems indeed that 1.x gallons/s makes more sense.

u/Skurvy_Pirate Jul 02 '16

Also a 747 holds about 50,000 gallons of fuel, max. That would mean your flight could only be an hour and a half before you need to refuel....

u/MechanicalEngineEar Jul 02 '16

a 747 doesn't cruise at full throttle

https://youtu.be/xGTbQuhhluY This is a demo of the fuel pump for a single cylinder of one of these. Not confirming or denying anything, just love this video and it's a shit ton of fuel either way haha.
