I have been Trying to muck around with editing the cars to make them faster or even a bit more realistic but somehow to no avail... What I have pictured is what I edited and I am only getting 200 HP in the game (original HP I believe)..
The torque numbers should be in newtonmeters. Did you use lb/ft? If yes, http://www.convertunits.com/from/lb+ft/to/N+m I see you have lots of torque on the low rpm's, if you put that torque in the higher rpm range you will get more horsepower. Maybe try and search a dyno output of the engine you try to replicate? I did the same with hellpig and the difference compared to the dyno result was only 2hp, probably due to me rounding off the numbers.
