For all those who reckon it's waste of time and money trying to extract more power from the already fine tuned Porsche Boxster here we have the results that will make you think twice.
My baseline dyno graph
This was dynoed when the car was completely stock. Done in 4th gear. Didn't bother to open up the engine compartment thus no rpm readings.
As you can see at higher speed(=rpm) there are many inconsistent dips on the graph this is where I expect an aftermarket headers would improve over stock headers. Im also interested to hear what do you think the cause of these "dips" might be?
Dyno comparison, stock vs aftermarket headers
In this graph the power curve explains itself. Noticeable gain across the whole rev range. 7WHP increase at the peak.
How much is this mod you ask. $475US and you can install it yourself.
Let me know what you think
