Project BMW M3 Part 4: Reducing frictional loses
|
Graph 1: Redline Fluids, AA HFM/Exhaust/21.5-lb Injectors vs. AA HFM/Exhaust/21.5-lb injectors--The new fluids and driveline helped reduce the "vanos" dip at 4000 rpm significantly while at the same time giving the Project M3 a handful of horsepower and torque to work with throughout the rev range. Notice how much flatter the peak torque is: Rather than seeing 214 lb-ft at an instant 4700 rpm, the M3 now makes 217 lb-ft of torque from 4320 to 4880 rpm! View Related Article
