There are several categories of race cars which compete at such an event-Top Fuel, Funny Car, Pro Stock, and Pro Stock Motorcycle (these guys are crazy-1,000 ponies on a 1,000 lb bike!).
The first NHRA drag racing event I went to was this same event three years ago. While definitely a neophyte, I have read on this incredibly manly sport and learned much from local experts. Let there be no doubt- we are talking the height of manliness.
The Top Fuel dragster division (the pinnacle of dragsters, pictured above and the ultimate in manliness) run on a maximum of 85% nitromethane and about 15% methanol also known as racing alcohol, instead of gasoline. If you think regular gas is expensive, the "nitro" used to power the engines of top fuel dragsters costs about $30 per gallon. Top Fuel dragsters use between 10 and 12 U.S. gallons of fuel for a complete pass! Ah, America! The engine generates about 3.4 times as much power as a similar engine running regular gasoline. These cars compete in a 1/4 mile race and complete it in less than 4.5 seconds at close to 330 mph! The fastest car that ran tonight went 323 MPH. Elevating overall manliness, a Top Fuel dragster accelerates from 0 to 100 mph in less than 0.8 second, subjecting the driver to a force about 5.7 times his weight. If you still doubt manliness, consider this- a dragster can exceed 280 mph in just 660 feet . The full race distance is 1/4 of a mile, 1320 feet. Unreal.
I'm sorry, there just isn't anything more manly, in the category of internal combustion, that I can think of.
To add to the manliness still- Top Fuel dragsters produce an outright deafening amount of noise -at full throttle, they generate over 120 decibels, enough to cause some peoples' eardrums physical pain, as I can wonderfully attest. As one drag racing publication puts it- "The intense levels of sound are not only heard, but also felt as pounding vibrations all over one's body, leading many to compare the experience of watching a Top Fuel dragster make a pass to 'feeling as though the entire drag strip is being bombed'."
Seriously, what could be more manly?
