horsepower is rated different today than yesterday. I do not believe that 797 would be 797 with yesterdays calculations. cars dont even weigh half of what they used to so If I was to guess, id say that 797 would not blow up yesteryear's drive trains!!

I truly dont know how the ratings have changed, but I do know for a fact they have strictly due to the lighter frames and body's of modern cars.

Prior to all the nonsense with emissions, car manufacturers released hp/tq numbers on a clean engine - no exhaust manifolds, no torque converter etc.

After the emissions and unleaded gas requirements manufacturers made engines with lower compression and released numbers that did include exhaust manifold etc - meaning cars appeared to “lose” anywhere from 30-100hp. The fact was they didn’t really “lose” any hp……the numbers were inflated b/c the customer never realized the advertised hp/tq because when they bought the car….they bought a car (that had a transmission, differentials, manifolds, etc) and not just an engine.

The math never changed, 1hp still = 1hp from 50 years ago. How the companies record and report hp changed. A 2022 Scatpack Charger puts out way more hp than 1970 440 6 pack Charger, and yes, way more than a 426 Hemi.

If you want to do a true test - throw the cars on a dyno and test the power to the wheels. General rule of thumb for a gas vehicle is you “lose” about 20% hp from the engine through the drivetrain, to the rear wheels.
