I cant upload photos so I will try and explain it
Had my car dyno tuned on a chassis dyno it made 152.5 RWKW and 501.5 NM of torque.
My question is at 4550 Rpm it made 152.5 RWKW and 438 NM of torque
Now if I convert these figures to 204.5 RWHP and 323 Ft Lb
I am led to believe that HP Is Torque x RPM Divided by 5252
So 323 x 4550 / 5252 = 279 HP
Is the above calculation right?
How come it does not add up to the dyno figures.
Only reason I am asking is my engine man told me he builds these motors and they make 357 FWHP so 204 at the wheels makes me believe that either the dyno is wrong which I doubt but then again the numbers don't add up, or there is something wrong with my combo
