[QUOTE="fabianyee, post: 380386, member: 6"] Actually, does the "HP = torque x RPM / 5252" equation works for all engines??? NA and FI.. hmmm.. too lazy to read that much or to do quantitative test to prove or disprove it.. Did a little brief calculation Case A: HP = 200 , RPM = 3000 Torque = 350 (not sure whether it's Nm or lbft, should be Nm) Case B : HP = 200, RPM = 6000 Torque = 175 what does it really mean?? hmmm... Case A seem to be more like the characteristic of a diesel engine. and B is petrol.. So the lower the RPM, better torque u'll get with the same HP... Better torque translate to better acceleration.. hmmm.. [/QUOTE]
