So I was initially a little disappointed , so I put the project on the backburner.....Well to make a long story short over the last year I made some very substantial advancements in pulling more RPM out of my engines...The P5XLT responded extremely well to these new changes and unlocked a top end I would have never thought possible from this engine a year ago.....With the changes made the engine has a more effective scavenging process, which not only increases power, it also increases the runtimes....
