I have to put in my 2$ (can't find a cents key). Okay, I agree with Mr.Nitro that boring a single cylender engine won't give much in the way of performance and thats absolutely true. Also, boring an R/C is pointless. (Switching the sleeve and piston is not however.) If you intend to build a full size and very competitive car for formular racing or something like that a boring job will almost be required. Why? Because everyone else is doing it. In proffesional racing money is not much of an issue and if you go through an engine every race it is not too uncommon. But again, with a single cylender it will not give a noticable performance gain.
1. Nobody uses boring to find performance, they do it to get the scratches out of the walls... The improvements are MINISCULE. A 350 at .030" only yields an extra 5 ci, just over a 1% increase in displacement.
2. Again, it isn't "because everyone else is doing it"
3. Your sleeve has a chrome or nickle coating, the sleeve itself is only made of brass... This coating gives the sleeve it's life; brass is entirely too soft... How do you guys intend to do this and leave the sleeve's layer of protection intact??
