Exhaust Port Pressure Traces

I am developing free software for design and analysis of expansion chambers for two strokes but need real life pressure traces as final confirmation of the validity of the software. An exhaust port pressure trace must be accompanied by engine port durations, RPM of the trace, and hopefully pipe specs and EGT. I´m not interested in pressure traces from other software. any help is appreciated.

never mind. I found what I was looking for in Blairs paper "Acceleration Test Method for a High Performance Two-Stroke Racing Engine". Read about what it has and how I made use of it at http://www.dragonfly75.com/motorbike/validation.html
