for those who state the rumour about HP is correct...
The gt500 - 2020 actually makes 790rwhp and 690tq :P
I said nothing, the engine will be able to produce well over 1000-1100 with simple pulley/e85/racefuel

And as we know the potential is only up who is willing to push it. but since the gt350 made 1300 with a twin turbo setup, I can only imagine what the gt500 with better rods and crank will do (y)
