Speaking only about OS engines, particularly the speed. The 2060 does it all, it's "thee" pipe for the speed and really the v spec. This pertains to OS though, since that's were most of my experience is i can't speak abt other engine brands. I did however find the RE10 pipe trumps the 2060 on a large track but rarely do we run on something with a straight that long. Ed at EB Mods told me what pipe worked on his engines, Neal will tell you what pipe to run on his engines. If you run a truggy Neal will pretty much tell you what engine and pipe to run and it will work on all tracks, same with buggy. I'm surprisingly pleased with Neal's B5 in my truggy, but i have the pipe and plug that is recommended. I ran speeds for a number of years and the Clockworks B5 has the speed beat in every catagory so far. I will be the 1st to say if it disappoints.
