This is part of my on going look at turbos and the relationship between RPM's and horsepower on RB26 engines.
The new line on this chart is GT-RS pump. That is a set of GT-RS turbos on a 2.8 liter RB26. It has what I would call mid sized cams in it. Lots of little tricks to make power. Its setup more as a real street car, so we tried to maximize area under the curve. Its pretty obvious from this chart, that we did just that.
