Man there are a ton of new people coming in this thread lately!!!!!! I think the new line is finally starting to stand up and be noticed for the awesome engines they are.
I now have over 15 gallons through my gen 5, 5port. Changed the rod twice and ceramic bearings were put in at 4 gallons. Never been pinched

It does desperately need a new crank though and the carb does have the newer needles in it.
Both of my GX race engines are around 3 gallons and at my last pro series event I did my last pit in my main and shortly after my receiver went out sending my truggy into failsafe. A marshall pulled my car off the track. I then went and marshalled an electric 10min triple A. When I went to pick my car up it was still sitting there idling away. Needless to say myself and several others were very impressed.
