Hi guys,

Just wanted to know how much fuel have you ran through your EVO3 .12 engines before noticing loss of power. Do you change rods every gallon? I have about 1.5 gallons thru mine and it is still running strong and stable. Temps around 230-240 F and no problems with carb leaks or tuning. I can get at least 5.5 minutes, maybe 6 minutes per tank but never pushed it that far. (TM G4S). It is not as tight at TDC but it was never tight even when it was brand new.

I was running a picco pipe until someone t-boned me. Now I'm back to Skyline VR12+. I had to turn the HSN one full turn leaner (12 hours) when I made the switch. Power seems comparable between the two pipes, so I'll stick with the Skyline cuz the price is like 2 for the price of one.
