In any era, the detailed power parameters of F1 engines are core secrets for the racing teams and engine suppliers. Outsiders can only estimate the approximate range through FIA document leaks and test speed, waiting for team data to be decrypted years later.
The 2.4L V8 engines of this era, lacking turbocharging, indeed show a significant disparity in paper performance compared to the over 1000 horsepower 1.6L V6 hybrid engines of later generations.
But this doesn't necessarily mean they are a lot slower!
Because the factors determining the speed of a race car aren't only limited to engine power, but also include the vehicle's weight.
The RA108 has most of its parts custom-made from carbon fiber materials, with a total weight just over 600KG. The ground-effect cars of the hybrid era, due to carrying batteries, turbo, and more electronic equipment, have a minimum weight of 798KG.
