Cool comparison of GT wheels vs. standard wheels
Although this is on a turbo buick, I think some people on here would like to read this.

Comparing a T-series T70 to a hybrid with a T-series compressor wheel and a GTQ exhaust wheel, and finally a full GT turbo with a GT series compressor wheel and a GTQ exhaust wheel.
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by GMHTP »</TD></TR><TR><TD CLASS="quote">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!</TD></TR></TABLE>
The turbo with the T-series compressor and GT exhaust spooled the slowest, and suprisingly the straight T-series turbo was the quickest. They started the dyno off at 5300 RPM's (Probably because of a large stall converter on the car) and recorded the time it took from boost to go from 8 to 23.5 PSI. For the T-series, T-series/GT, and full GT turbos it took .6 second, .7 seconds, and .66 seconds, respectively.
