Yes i am wanting to mod a 0s .40 engine i have as a spare and just see what it will do. I know it will shorten the life span of it alot but it is a spare and we would like to see one really jacked up fly once. I have a read in some forumns that some extreme mod folks can achieve 30,000 to 40,000 rpm for short periods of time. Can someoen direct me to a company that does these type mods? Or to directions how we could in our machine shop we own. Thanks for any help you may give.
What specific OS 40 do you have? There are some things you can do to improve top end power but the cost of doing so gets close to buying an engine that has the performance stock
