A bit of help needed please
Hi Guys,
A bit of help needed to help me understand wheel tq and crank torque.
I have read about whp and bhp, and the amount of variations and how depends on percentage lost, then the amount of BHP converted from WHP is different. And also how different dynos react and give different numbers.
Is this the same with Wheel Torque and crank torque?
My dyno reading gave max torque of
359.41 ft lb at 4310 rpm (pre map)
392.68 ft lb at 4270 (post map)
What does those figures correlate to with regards to crank torque? Seeing that most specs sheet gives 443 ft lb at 5000 rpm?
I have search extensively and cannot find a calculator online and cannot figure out the calculations with the rpm and wtq.
Thanks in advance.
(on a side note, i am trying to understand all these and not trying to boast large numbers etc etc.....)
