- One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. They have over half as much horsepower in one cylinder as a Dodge Viper has in all ten. No one has ever successfully run one long enough on a dyno to get a horsepower reading. Current estimates are right around 11,000 horsepower.

With a gas or diesel engine the engine has to spin to provide any power at all to the wheels. If you want more power then you can only add more fuel up to a point.
At some point getting more power out of an engine means you have to have the engine spin faster.
