The 5 port is going into my GS XUT Pro Truggy which currently is running the original GS R25MT engine.
I was amazed at the pinch on this new Go tech engine. I have 3 tanks through the engine using the heat cycle break in method (running at around 95deg C). Heating engine with heat gun and loosening off the glow plug every time I start it (I have to otherwise my starter box won't even look at turning it over !!).
I currently have a JP-3 pipe on my truggy which works really well with the original engine, but I gather from what I have read here that this pipe is not really suitable for getting the maximum performance out of the 5 port. What would you Go Tech experts recommend ??. Most of my racing is done on relatively tight, medium length tracks. Any advice would be greatly appreciated

run the 086 pipe, being the 5port has so much bottom end you will never have to worry about having enough low end power for short to med. size tracks...
