TTA vs GNX ??

The GNX was said to run 13.4 and the TTA a 13.5
IN all honesty it was mainly because of the ceramic impeller allow quicker spool and the better from of the G-body allow better launch. The TTA made up a little bit of the slower spool and launch by being lighter and more aerodynamic and having better flowing heads. All in all they are so close in stright line perfomrance it would come down to drivers abilities
Thought the GNX had it in the Skid bad though, but the GNX was funny about how it handled. Frm the way I understand it it had a lot of push, but would stick. Just somethign you would have to get use to where as the TTA was a littl more balanced.
