| "Sonic Testing " That's the name I couldn't get to the top of my head in that first post,, sorry about that. But this is expensive, but if you're after maximum power, you need to know how thick the cylinder walls are. A sonic tester can tell you exactly how thick the wall are. It is the best tool for finding core shift in areas that you cannot measure. Remember do not assume that boring it to the largest size will make more power, it wont. Thinner cylinder walls are weaker and do not dissipate heat as well. You want to remove as little metal as possible to get a new surface. Look at Wagz and a few other that went with a 87.5mm piston on their new rebuilds, landing over 740rwhp. Something to think about I guess.
