The engine management software is the key to fine tuning these monsters. Truly at this point the limit is fuel quality...the mapping software tells you real quick where octane limits timing advance/power. Tommy's software has a unique sensor that isn't only a knock sensor but measures the best audible qualities of the actual combustion explosion and adjusts fuel/air/ignition to duplicate the optimum "audible" characteristics of each combustion cycle. What's even more mind boggling is that he can sit at his desk and measure/change these characteristics in a clients engine remotely...anywhere!!! .

Not sure? I know the IHRA Pro Stock guys twist them past 8500, but, not for very long and they change valve springs quite frequently. The nice thing about a motor this big is you don't have to spin it up as high as a smaller motor to make huge power.

Not a big deal when you compare the #'s in this thread to 100's of much smaller motors.
I have a 171 cid RB28 in my car that makes 800+ hp on 93 oct.....so a 557cid would have to make 2600+ hp to compare
Mercury made the best move so far.
