The eXtech has been a good motor, I ran it in truggy, until I sold truggy, then used it in buggy w/2057 pipe, and like it alot.. Fuel mileage could be better, but it take great trigger finger to keep tires from not breaking loose at every corner.. I did have it pinched once at 4 gallons, but it was entirely my fault, it was lean, and I didn't recognize soon enough, and when it started running poorly I leaned it more rather then richen, which caused this motor that normally ran around 210 to hit nearly 300, and it lost compression almost immediately after that.. But I learned a very important lesson..
PitPop when you all do test, will you try the 2066 pipe at all? I ask because it is offered in a couple of the orion combos for the Alpha.. If I can get a combo that works well then I would just as soon do that, but have no problem running/getting a different pipe either..
I think the 2066 was originally for the US Spec? I will see if we can test with that pipe and give you some feedback. The Alphas seem to like a more free breathing pipe, so I can't imagine the 2066 to be performing better than 2013 or 2058.
Let me tell you, the engines have changed SO much since your EVO4 and the previous engines. This newest generation of Team Orion Alpha has absolutely no parts in common with the older engines. Completely redesigned combustion chamber, totally different porting and timing, different materials in the piston and crank case, new aluminum body carburetor made specifically for Team Orion... wholesale changes to the point there is nothing in common with the engines from 2 years ago.
