I've raced a stock WRX from a roll and it was pretty much even until top of mid to top of 4th when I started to walk away. I was ahead by nearly 3 cars by 220km/hr where my car felt like it may have been close to topped out. I think the furthest I have ever seen the spedo is somewhere just under 230.
My car is a 98 SVT with a modified stock ypipe, pulled resonator and a KKM. I must add that I dont keep weight in the trunk either. I have no spare in there and my sub box is a single 8" bandpass I built which is probably 15 pounds.
Anyway I was not that impressed. I also spoke to a guy who has a Prelude SH with a filter and exhaust and he said he's raced two on the highway and he managed to edge both out.
