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.



Yeah, so what are the MPG Highway/City numbers?


It should be gallons per mile.

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

Well, let's see:

It burns 11.2 gallons per second at full throttle.
It does the quarter mile in 4.4 seconds.
That's 49.28 gallons per quarter mile
49.28 x 4= 196 gallons per mile or:
..0051 mpg

Of course in reality it would never run for a full mile at full
throttle. Even if it had enough fuel, it would blow up first.
