Thanks, that is what I was looking for, and reliability (within reason) is one of the goals.Lets take extreme swings so the differences can be easily seen. Im simply going to use roundabout numbers. Lets say your blower is maxed out and capable of 1500 hp. Theoretically with the proper provisions to accommodate different engines, that blower maxed out will generally make 1500hp on a 2.0l engine or a 7.0l engine. Now obvious differences will be pressure in the manifold for each engine. Lets say 50psi and 25psi respectively. More power will be needed to turn the blower to compress 50psi and along with that comes more heat.
A slight increase in volumetric efficiency in your case with porting the heads may result in less parasitic loss to drive the blower and a touch less heat. But is that quantifiable? Will it add up to anything at the track? Likely not. Blower setups are basically limited to the capability of the compressor. Spend your money on things that will improve reliability like good rods and a trick set of valves.
