Hi,

There are lots of ways to calculate horsepower and there are different types of horsepower, Nominal, Indicated, Brake, Shaft or Effective horsepower, it is generally it is expressed like this:

- Horsepower is equal to the weight of the vehicle times (Speed in Miles per hour, divided by 234) raised to the third power.

HP = (Weight X ((MPH / 234)^3))

Andy here at Ross-Tech has touched this subject in the past:

Thanks !


Some one can now explain this ?":-) "Do at least a test run and log engine speed and velocity with VAG-COM / VCDS to a log file."

Which parameters exactly should I log ? There is so much !!!

That what I Did

Module 1 >> 8 >> on the first line 138 on the second 120 and on the third 113

Then The nM * 0.738 which will give me me ftlb and then RPM * the ftlb and /5252 which provides me 245hp :)

Thanks to all!
