Agree X10! 1000 ft drags are abominable.

I began going to AHRA events in the early 70's. Things were quite different then. 1500 horsepower was the oft quoted figure for fuel motors then. Now, it's 10,000 horsepower. Now, they're racing the track. Track conditions change greatly with temperature and the NHRA does its best to present a good surface to all the racers. I attended Friday qualifying at Topeka in May and was impressed with what I saw - most all fully powered passes in both TF and FC. And the total auditory/sensory experience of the fuel motor cars. It's something everyone should experience once in their lives. Short of a Saturn V launch, there's nothing like it.

Just an FYI, the 10,000 HP figure that is now widely mentioned, is still on the low end. It's in the vicinity, but still far too low most of the time.

The way we know this, is measuring the driveline shaft deflection. If a driveline of known strength deflects X amount, we know there is X amount of torque being applied to it. From there it's a simple mathematical equation to determine the HP.

Of course we don't measure shaft deflection to determine the HP. That is just a side effect of data-logging the clutch performance.

I used to laugh at the often quoted 8000 HP figure. For at least the last eight years, it has been far beyond that.

Little known details! Thanks for those gems. Maybe one day we'll have a dyno for ya. Those runs would be ferocious...

How were you measuring driveshaft twist position? Strain gauges?

Well... lets just say there is more than one way to measure the torque being passed through a driveline.

Racing is using more fuel than ordinary driving. One question, is the fuel tank of motor bikes,cars are bigger than ordinary vehicle?

It is? Additionally, what is "ordinary" driving?

What motor bikes and cars? What is an "ordinary" vehicle?

I have no earthly idea what the question/statement means. It reads as if written by a person for whom English is at best a second language.

Fuel cell size is usually determined by the regulations set by the sanctioning body.

I agree with you. That's why I asked for clarification.

I stopped watching and attending NHRA events when they went to the 1,000 foot mark for the fuel cars.
