Default Engines and acceleration

Since boats have engines and for a change of pace, I thought I'd
share some info I recently received from a car nut. He's talking
about a custom built, 500 cubic inch dragster engine based on the
Chrysler 426 c.i. hemi design.

Here's a short list of it's specs and acceleration capabilities:

Produces 8,000 horsepower. That's more than the first 4 rows of cars
at NASCAR's Daytona 500.
Consumes 11.2 gallons of nitro methane per second at full throttle.
Dual magnetos supply 44 amps to each spark plug.
Capable of reaching over 300 MPH +... before you have completed
reading this sentence.
Redlines at 9,500 RPM ... only does 540 revolutions light to light in
the quarter mile.

To put this into perspective:

You are driving a new $140,000 Lingenfelter twin-turbo powered
Corvette Z-06. Over a mile up the road, at the beginning of a
measured quarter mile, the dragster sits, ready to launch as you pass
by it at 200 mph. The dragster launches as you pass by and starts
after you. You keep your foot buried hard to the floor, and suddenly
you hear an incredibly brutally screaming whine that pummels your
eardrums and within a mere 3 seconds the dragster effortlessly catches
& passes you. He beats you to the finish line, a quarter-mile away
from where you passed it.


Like this one? Fast.

I want to quibble with the 540 engine revolutions for 1/4 mile.
But, the numbers tell the story.

Average drag tire is 30" tall, for a circumference of 94" or 7'10".
1/4 mile is 1320ft. 1320 ft / 7'10" equals 168.5 wheel rev's down the
track. Assuming a final ratio of 3 to 1 (motor to wheel)
3 times 168.5 = 505 revolutions per 1/4 mile. (does not include wheel
spin. Damn!
Mikek
Fun Fact.
When I was kid my grandmother lived 7 miles from Martin Dragway,
On Saturday nights we could hear the dragsters run the 1/4 mile from her
house 7 miles away.


Yeah, 540 revs is not correct.

Could you back that up? I just showed you my numbers, were do you
think I went wrong?
I didn't think his number was right either, then I did the math.

iBoaterer just wants to argue about a difference of 35 rpms. Could
be due to wheel slip, could be that they used slightly different gear
ratios ... could be that the driver didn't keep it in perfect
alignment ... whatever. The point of the original post was that the
engine turns surprisingly few rpms in a quarter mile because of the
phenomenal acceleration.

How would it get that kind of power to the ground? Traction would be
difficult.

Tires and weight shift. Probably a coefficient of traction greater than 1!

More like 633 revs. For 4 seconds at 9500 rpm. Not including startup,
burnout, and shutdown. Also takes the power of one cylinder to run the
supercharger, and is near hydro lock with the amount of air and fuel.

---------------------------

633 revs assumes it's red lined at 9500 rpm throughout the entire
quarter mile. I don't think that's so.
The 540 revs given in the article was an approximate figure because it
doesn't take into account variables like wheel spin, etc.

Mikek's calculations seem spot on for a theoretical perfect run, light
to light with no wheel spin and not accounting for burnouts done
beforehand.
The article stated that Including the burnout, the engine must only
survive 900 revolutions under load. It's then rebuilt.

Other specs sent about this:

0 to 100 MPH in .8 seconds (the first 60 feet of t he run)
0 to 200 MPH in 2.2 seconds (the first 350 feet of the run)
6 g-forces at the starting line

At a redline of 9500 RPM's that is 158.3333 per second. 4.5 times that
(the time it takes to go a quarter mile) is 712.5. And that is not
including wheel spin, which by the way in a top fuel dragster is nearly
the whole run, and you could easily double that.

Again, you assume the entire quarter mile is run with the engine at
