Although mags claim the 1/4 mile to not be much better than the SS, at higher mph's say 0-140, the gap SIGNIFICANTLY widens in favor of the GT500. Also the mph C&D got is down (alot) from what some of the other mags got...so it looks like stock for stock SS vs GT500 won't be as close as what some folks are hoping....

again, the average GT500 puts down high 430's/low 440 rwhp. If the new GT500 has 40 more hp (~35 rwhp), how much is is 435-445 rwhp + 35 rwhp? it's not that hard. Both the outgoing GT500 and the new GT500 have SAE Certified engines, so we already know what they really make and based on the outgoing GT500, it is VERY safe to surmise what the typical driveline losses should be.
