Anyone who questions the GT's superior power potential can check out the dyno chart: all else being equal, just going from the standard to a GT exhaust wheel netted 6.4 horses and 22.7 foot-pounds at the rollers. The full-on GT turbo added an additional 14.5 horses and 7.6 foot-pounds at the wheels over the hybrid. And overall, the difference between a T-series 70 and a GT-series 70 is 20.9 horsepower and 30.3 foot-pounds at the wheels! Also, Hartline says that at higher boost levels, the GT would have widened its lead on the other turbos. As an aside, a high-boost run in the GN pushed the GT-series 70 to 29 pounds--and recorded 642 horses and 584.3 foot-pounds at the wheels!
