Is this consistent with what you are making on your current setup? Reason I ask this is because the kind of loads the bearings have to endure are directly related to the torque being produced as well as the kind of RPM's you subject them to. If your setup is making under the ~500RWHP level then it wouldn't be an accurate comparison to the question at hand. Albeit, I've had the experience with setups like what you are doing - hats off to you. :) Its nerve racking enough to make 500+ RWHP on an 8.5:1 engine and keep an eye out for things - making even 300RWHP at 10.5:1 takes nearly religious dedication to hold it together. :) Enthusiasts soon understand each other. --W.
