I think that would help to explain the great ETs but the lowish trap speeds you were seeing. Get the CATs down and you've got an 11 second car
Let me ask you a question, what are CATs? Is that the same as IAT's? Well if it is then your telling me that if your IAT was as high as 180 deg. that the timing corrections had nothing to do with det. or knock? I'm not saying the car was knocking, but the whole idea of the timing corrections is to prevent knock right? An the point I was really trying to make was that the e85 benifited him more then say 93 octane by itself where even more timing would of been pulled.
