Rear wheel numbers are divide numbers by 0.82 to get estimated crankshaft HP:
115hp / 160tq at wheels, uncorrected, stock IP
141hp / 201tq at wheels, uncorrected, hybrid IP
140hp / 195tq at crank, uncorrected, stock IP
172hp / 245tq at crank, uncorrected, hybrid IP
EGT's remained below 1300 (maybe under 1200) on the dyno, no worries there. Did two pulls, the runs were nearly identical. I'm not convinced that correction factors (SAE or otherwise) should apply to turbocharged applications, so I'm sticking with uncorrected / raw rear-wheel numbers for now. The numbers are even higher when a correction factor is applied. Winter blend fuel is probably costing a few HP, ditto for the heavier brakes, wheels, tires, and diff.
Note how power stops climbing around 4000rpm due to lack of air...the boost pressure drops past this point and power slides down with it. Too bad the dyno doesn't have a boost pressure input, I'd love to see a boost curve graphed along with the power. Need bigger turbo!
