Mach428 said:I've seen a handfull of machs run 13.3- 13.1 bone stock. Most of the 04 Mach Dyno at around 280 hp more or less putting them at 320-330FWHP. Unless the 05 is significantly lighter, I believe the Mach will have an edge in acceleration, not sure about handling, Mach come stock with Tokico and they are 3/4 of an inch lower then the current GT, seems to handle fairly well, and gets excelent traction.
Don't forget that the 3V - 05 motor has variable cam timing and a 2 stage intake manifold. I'd bet that it has a lot more low end torque than the Mach 1 motor.
The Mach may have a slight acceleration edge because it will be 100 or 200 lbs lighter and it has smaller diameter tires (same axle). But the 05 with its MUCH improved suspension geometry and its vastly better F/R weight distribution it will easily out handle the 04 Mach 1 and it will ride much better too.
