Impulse buy: 2015 Fiesta ST

[ScottyB]

i'd consider what the trans was meant to handle. these little cars with the tightly packed 6 speeds don't have huge gear tooth surfaces or big heavy cases. i don't think chucking more than 150% torque through them is likely a good idea. might want to call it Good at stage 2.

i know its a different car and all, but Si's like mine generally start stripping teeth around 300 lb ft. its not the horsepower necessarily, its a huge slug of torque all at once, even with wheel slip.
