..and the Z can actually take corners. You don't see many TTZ's at the drag-strip for that same reason. They don't launch as well out of the hole but pull stronger and smoother on the highway. There are Z's here that drag though and some are in the 11's on STOCK turbos. Also, there are members here who have DYNO'd more than 400 to the wheels on STOCK turbos. If you want a straight line drag-racer, get the Camaro, if you want something that can take turns or like doing highway rolls, get the Z. As for the Z not being able to run for a long time, tell your buddy this sure looks like a Z that can run for more than 15 minutes.
