Does anyone remember the wankle engine?
LDL, are you a rotary man? very complicated to really explaine power, it's more to do with the quality of the power. also just knowing what HP or KW a motor makes @ the flywheel from a test on a similar motor and the factory does not realy tell you much. that's why i look at what Torque the same motor puts out & at what rev it starts making the Torque at and how long it holds the Torque for. like diesel's make Torque early but it also falls off early so waist of time reving a diesel.I have used Dyno's over the years and then have gone to the track and raced the same motor and got a computer time slip to show how long it took to cover the first 60ft, then how long to cover the first 330ft then 660ft and what speed i was doing @ 660ft the 1,000ft them quarter mile and what speed after quarter mile.sometimes i would tune for all out power. i would go to track and all i saw was i got to a higher speed at end of a quarter mile but i did not get to the speed in a shorter time span took me just as long to cover quarter mile as it did with less HP.then i would go back and instead of just going for all out HP and runing the graph on a RPM i would do a timmed Dyno run where the dyno times how long it took to make so much HP & so much TQ. i would just give it three pulls on the dyno to get a base line reading as i last raced with but timmed, then i would make adjustments to the tune to see if i could get more TQ & more HP to come in at less than 4seconds wide open throtle if i saw a big gain in HP & TQ in less than 4 seconds WOT compared with my last tune but in total less HP than i now had but not timmed HP. i would go to the track and do a quicker time and faster half track speed. so i put this down to Quality of the power and TQ.hard to explain cheers
