Those are great numbers at 19psi. What is your comp ratio with the spacer? I was not doubting your numbers or your beast. Like i said, my example was an estimate of what i have seen. It also is an example of why some of us want to play with the R head.
My goals for this build is to max out injectors. The only question is at what power level.
My entire motor is overbuilt for the fwd chassis anyway. The bottom end and R head are built for 6-800awhp in an S4 chassis down the road. The true benefit to this head is efficiency--same power levels at lower boost.
Thanks for the comments--keep 'em comin...
