edy, right now the highest rpm i have achieved is about 4500 rpm. i had a issue with too small of fuel injectors starving me of fuel around that rpm. i was using 6 42 lb injectors. now i have 60 lb injectors and can't wait to get them in and test it. i hope to be able to support full power to 5000 rpm and really not any higher. 292's , from my experience have bad harmonics around 5200 rpm. i have mine balanced and have a good balancer also. so to answer your question, max power 4000-5000. that is also at 15 lbs boost. tom
