Tonight this SRT4 followed me out onto the road. Then we raced from about 30 - 110.
I down shifted to 3rd gear and was around 5500 rpm. He was at my back door, then I shifted to 4th and I was gone.
Id say I beat him by about 5 cars, then he gave up.
I am stock with no heatshields. (STi).
I dont know what he had done.
EDIT - Just found out it was a 2004 SRT4 with a BOV.
