The most powerful engines are on Dragsters

[Robert W]

I am talking of automobiles and not rockets. Top fuel dragsters run for around 900 rpm. This short time ruins the engine. Mechanics at the tracks must rebuild the engine to run again. Imagine you had to rebuild your car engine each 3 second run.

Anyway an expert will explain how this works and tell you the cost of a run.

The Pratt and Whitney R-2800 Wasp engine was capable of 2200 horsepower and could propel a fighter aircraft to 400 MPH. In 1944.

Zoom, zoom.

Zoom, zoom.

Dragsters have 11000 hp and speed the car to 338 mph in 1000 feet.

Back in the 1960s and early 1970s I ran at several dragstrips in the mid-West and South-East. I didn't rebuild the engine very often but I did have to replace blown clutches and pressure plates often enough. I was a power-shifting Mo-fo!

I think you meant to say 9,000 RPM.

I can't remember the actual numbers but each cylinder on a Top Fuel dragster puts out over 1000 horsepower.

Yeah, 9,000 rpm isn't that much. F1 engines can run 22,000 rpm, it's the power the Top Fuel engines put out that's impressive.

Therein lies the rub. Everything that makes top fuel racing fun and exciting is essentially eliminated if you replace them with an EV.

Well, yeah, but as the video sorts of hints at, those F1 engines are a totally different breed with narrower bore and shorter stroke designed to run continuously at very high RPM. They make up in speed what the top fuel does in raw POWER.

Like a thousand small lilliputians working together compared to one atom bomb.

 

[Robert W]

I think you meant to say 9,000 RPM.

No, the surprise is they only need to turn over around 900 times. Close to that figure any way. I see figures as low as 500 revolutions. Bear in mind if the rate is 9000 rpm, the time to spin is just under 4 seconds. The report of 900 has to include starting, idling and racing.

F1 engines do not get up to 11,000 hp. Top fuel engines do not run for long.

EV dragsters have not got close to the nitromethane engine dragsters.

 

[Robert W]

I think you meant to say 9,000 RPM.

Well, I was a tad sloppy in calling it pm. The total times the engine spins per research is from 500 times up to 900 times. Not per minute, total turns. The trip is less than 4 seconds.

you need to learn some math,,

500-700 RPM is idle speed for a street car a top fueler idles at over 2000 rpm..

Well, 900 rotations would cover about 10 seconds of full run time. I'm not sure you can count idle, as that is low RPM/low power operation including getting the car up to the gate and staging, not near the stress that is involved in full output.

Yeah, I know, I had a buddy who used to build and race bracket racers. I built street cars out of used pro engine parts from the Allison brothers. An F1 engine is a totally different animal built for very high RPM and long endurance.

Well there is burnout happening. Anyway until the math is used, one imagines they spin thousands of times in a run.

You confuse speed with power. Some relatively slow farming equipment tops 1000 h.p. The open class in tractor pulls is HP off the freaking charts.
