All this reading and playing around has made me very nostalgic. I removed my P5X from my X1 buggy and decided to run in a new GO 5port.
It was very difficult for me not to get the dremel in their and do some mods.
This time I was after runtime.
All I can say the difference between P5X and Go 5port is very noticeable.
Better runtime and better bottom end and balistic topend.
I made the head shimming 0.6 as suggested by Massive.
I couldnt get my temps very high. If I leaned the sucker more it would just choke on the straight. It seems the GO's tuning just that, tune and leave it. If you go too lean on the LSN it lean bogs middle tank to empty as stated by Mark.
Anyways here is some video footage.
My buggy is the Silver with red wing
My truggy is the silver with black wing.
Both missiles is powered by Go 5 ports.
CRT is 5port with JP1
Buggy is 5port with JP3
