Yes, and that is high end engineering, lets see your engine spin at only 20 000rpms.Hp per liter is meaningless, but tq per liter is not. All you need for more hp is to spin faster, getting torque without using gearing is much more difficult at a set displacement.
Well in most cases you do, and HP/TQ produced per X amount of displacement is HP/TQ per liter (liters being my units of displacement).Simply put: my view is it matters only if you have all the numbers to compare the engines to each other. Then Hp/TQ produced per X ammount of displacement matters.
HP is what wins races. An F1 engine will produce a litter more Tq than your car. HP is the ability to do work over time. if you have more hp than another engine, than you can perform more work in a given amount of time. No matter what engine, if you are racing, you would drive it around your peak hp band, this could be away from whare you make the most tq. When you aer pulling in your accord, you dont hover at whare you make peak tq do you??? naw you feel it at peak HP.My favorite example is the Rx8's renesis engine vs the subi wrx's ej20T the RX's makes a LOT more hp, however its tq sucks balls.
maybe its just to put up with racing all day?:confusedThe other thing I don't get with that car is that it has a twin disc clutch setup for a small engine that doesn't need that kind of tq handling capacity.
Both HP and TQ per displacement is an engineering feat and means a lot. Every efficiency that there is in designing an engine will directly affect hp/tq per liter.
These Efficiencies have a direct result on your BMEP, BSFC, and so on yada yada.
So if HP per liter doesnt mean anything, than you are stating those stated efficiencies are non relevant to engine design in terms of performance. Torque is important for sure, but Torque is just a result of displacement. For sure the stated efficiencies will effect torque as well but most engines can get close to a full cylinder charge at some-point which would be where they make most torque, what changes how much torque they make, will depend on how big that cylinder is.
I think that both HP and TQ produced per liter is amazing and the whole reason why I like engines but I also believe that HP per liter is more of something to be proud of as an engine designer because it probably means that you have designed an engine that can spin real fast and breathe at those higher rpms.
It is just matter of opinions but to state that HP per liter doesnt mean anything is just looney.
