WTF! All these dudes with non turbo cars think they know what they fuct they are talking about. First of all, a BOV doesn't make power. Since the weather is cool the Evo won't have problems with the heat but the tires will be cold, so 13.3-13.5 with a good driver could be attained.
I went to the track with a guy with a RX7 tt with minimal mods and he was almost hitting high 12's. The key point here is that his slowest run was a 13.3 and his runs were consistent. I am not saying the EVO would have been smoked or vice versa but the run would have been real close.
