If I'm not mistaken the HX 40 is almost 3mm larger than the 60-1.but realistically they are literally neck and neck on the compressor side. I would have to say probably the hot side of the HX40 is the bottleneck. I'm not knocking the 60-1 for a p-car, it just runs out of steam the more you push for power. It works well just on the mid scale. When you want more it gets too close to the surge line.
Nope, both 60mm's except for my 8 blade, which is 58. There were some 56mm's out there too, but they're oddball. Not to be confused with HX35's.

You meant choke line, not surge? Surge is when the compressor outflows the engines airflow.
