6000 rpm = 100 rps(revolutions per second)

100 rps x 10 second 1/4mile pass

=1000 revolutions of the engine down the drag strip.

Obviously there's the burnout and drive back to the pits but just making it easy

Now in a 20 minute race.

6000rpm (revolutions per minute) x 20

= 120,000 revolutions per 20 minute race

Now the eshaft/Crank does 3 revolutions for one full rotation of a rotor

So in the drag race you take 1000 revolutions and divide that by 3

1000 / 3 = 333.333 ful rotations of one rotor

So a 2 rotor is 333.333 x 2 =666.666 full rotations

For a 20B x3 for a 26B x4

So in a 20 min race

120,000 / 3 = 40,000 full rotations of one rotor

Then multiply that number by how many rotors etc

IT is very interesting as (like myself) everyone thinks that a drag engine is a good testament to a solid built engine.

As the saying goes drag racing outs the most amount of stress on an engine in the shortest amount of time...

However if you look at a circuit car, Clives car as a perfect example, just how much abuse it has done.

5 years with the same engine.

6 race events per year?

Qualifying sessions

20 minute races

At 500hp

That just shows how good the engine is and also how well tuned the car is

testament to the guy that built the engine and also to guy that mapped it, and also nit forgetting the Driver Clive

Now there's a huge amount if variable to consider etc, traction being a major one especially in drag racing because traction puts huge loads onto a drag engine, acceleration a car from 0-60 in 2 seconds at a guess which is a lot different to a track car.

Just looking at the numbers you have got to appreciate how good an engine has to be for drag racing but also on track.
