How much can you stand? As much as you have time to write, Lynn. There are a bunch of us running, or planning to run turbos, and the more we can learn about how to operate them the better. For example. On my Cozy IV I have a '93 13B REW with high compression rotors and an intercooled hi-flo (T04-V2) turbo. I blew the turbine wheels off two stock single stage turbos by overspeeding them trying to find (and finding) the limits. What boost, oil temp, water temp limits would you recommend at sea level and 10,000 ft? Note: the RWS EC2 fires leading & trailing together and gradually retards timing with boost. Normal fuel is 93 octane, but I'm probably going to be forced to fuel it with 87 octane mogas and/or 100LL on occasion. What boost limits would you set under these circumstances? Any other thoughts or comments on this setup? Regards, John Slade (currently single rotor turbo 6.5B)
