NHRA. Power beyond

Propulsion Top Fuel and Funny Car cars participating in the NHRA championship without a doubt are the most powerful units that have ever installed in the equipment, at least similar to the size of the car.

Indicators of these motors could hardly fit in the minds of even savvy professionals and have long been beyond good and evil. But, unfortunately, not yet invented a dyno-stand that is able to withstand a devastating moment, which generate the 8.2 liter monsters that absorb gallons of nitromethane.


In earlier times it was sufficient primitive calculations to roughly determine the level of impact of these engines. Technologies developed and horsepower grew exponentially. If in the seventies it was a couple of thousand, then in the next decade it has doubled the power, and at the crossroads of the twentieth and twenty-first centuries, engineers have articulated figures at the level of 8, 000 hp A few years ago, it was carried out large-scale study in which with the help of computer simulation on the basis of a number of indicators have already been obtained a result of 10 000 hp

And most recently, Mike Green, the chief mechanic eightfold champion Tony Schumacher's team, decided to make its own study.

To do this, we developed a special sensor that measures torque directly from the engine crankshaft installed in Top Fuel dregster. After a few «combat» races were held simple calculations to determine the actual performance of the power plant. The figures have to admit, impressive. Although it would seem, where it is more...
