Good post, I agree. Your final point seems most relevant to the Monaco GP. If you look at the speed trap results, the Ferraris are no where to be seen but in general lap times they are ominously fast. I guess the cars have been optimised for torque, rather than peak power. On the other hand, the Mclaren is the fastest in all speed traps and it is quite apparent most of its power comes in at higher rpms (loads of high rev instances, looking at on board footage, as well as much more wheelspin in 1st through 3rd).Jersey Tom wrote:I wouldn't say that longer intake (or exhaust) primaries gives you "more torque" and that shorter gives you "more power."
IMO from experience.. exhaust and cams have more impact than intake, but.. even then..
Longer intake and exhaust runners gives you more torque at low RPM. Shorter intake and exhaust runners (and more valve overlap) gives you more torque at high RPM.
The amount of torque the engine can produce at 100% VE is mostly going to be determined by fuel, combustion chamber design, bore/stroke, BMEP, etc.
Valvetrain, intake, and exhaust determine where that torque is most available, since volumetric efficiency is speed sensitive.
Torque and power are very, very closely related. Power is to a degree just a measure of where that engine torque is available. Since they're not really that different they're both equally as important. Power though is really the ability to do work and the ability to get as much energy into your vehicle as possible.
My Nissan 350 probably puts out as much peak torque as an F1 engine. Maybe even more. But in no way would I be capable of beating a grand prix car in just about any maneuver conceivable, since the F1 engine can place that torque so high in the RPM band, and through gearing can develop outrageous amounts of torque at the wheels.
Power, torque, gearing.. all equally as important.
At Monaco, getting lots of power down out of slow corners is important. Best way to do that is just by gearing. Making the torque come on lower would have the same effect and would make the car a bit more "street"-like, but you'd lose that top end at the outright ability for the car to develop heaps of power.
