I am taking the Q4 to Calder park raceway this sunday for a club sprint event.

So far I have removed 155Kgs (thats 340 lbs) from it, removed the cats & pre cat and changed the inlet to a "pod" style filter. Apart from that its still just a "standard' Q4. I have also hooked up a 2nd MAP sensor so that I can map the cars boost vs RPM curve on a datalogger. I have used the MPX4250 MAP sensor made by freescale as this is the one that the "megasquirt" systems uses so there is a lot of information about how to map its voltage output to a pressure reading. I am planning to get some video as well if things go well!
