Due to the hydraulic roller, I limit RPM to around 6200, though it is still pulling like a freight train. However, torque output down low is so great, I don't feel the need to spin it any higher, the is very little loss with the rpm drop during the shift. Again, predominantly at hot street car. If the car was more focused to track time, it would have a solid flat tappet cam. Another point of compression, along with a bigger solid cam and it is a 600+ combo all day long.
