Compressor Map

(Click to see larger image)
That is the compressor map with the boost pressures that we are going to be in on that turbocharger....

The lowest one is what we will be at but I pot some points for a little more boost pressure so that if we get as far as a built block what we will be working with.

The points on the lowest line are for what we will use @14psi of boost... you can see how the flow of the turbo will be used as the rpm's increase and for 14psi I think we will be very very good with lots of meat on the center of the map = lots of fat torque and tractable power.

What you will see on the left side is the pressure + atmosphere that will be used and the bottom is the flow at a specified rpm point. Its hard to learn how to read a graph but its pretty damn cool when you know what you are looking at. I had graphed the map since i was looking at this turbo to make sure that this turbo would even work for us becuase if the map is off the graph one side or another then thats bad.

one side of the bad side is that 1. the turbo is not being brought up to speed by the exhaust gas 2. the turbo is going too fast because its too small 3. the turbo is blowing (aka. surging) too hard thats like a person having a heartattack.
