So who brought up the Comp Eliminator and Pro Stock engines. Yes I brought up F1 engines only to illustrate the difference in displacement, torque and HP. I also mentioned large industrial and marine engines to illustrate the other side of the coin.
No worries about the horse and buggy comment, even if they do have their place. Actually still used a lot in eastern European countries. I am fully aware you can go out and unload a pocket full of cash and come home with an American built supercharged car off the showroom floor that develops 700+HP and revs to 7500 or more RPM.
You also chewed out another poster for not understanding your viewpoint and thinking over 6k RPM must be a race engine. Possibly it is time you consider it is you who does not understand.
3,000RPM for most engines built for street use as a start of a dyno run is not lugging the engine. For a race engine designed to run to 9500+ RPM, maybe so.
