BigTex-I am already running 28x13.50 ET Streets. I really think it needs a 30" tire. And some drag shocks and maybe battery relocation, etc. I know you have always complained about the whipple and its performance in the heat but I don't really have that prob. Yeah it falls off some, but every vehicle does supercharged or not when it gets 90+ degrees. As a side note I did recently install a IAT downstream of the blower so I can monitor outlet temps and it is pretty scary. I think I'll start a thread about that topic.
