Hey everyone im new around here dont post often but i had a few questions. First, what is BPU? I know what it stand for but is there any set definition of mods you need to consider yourself "BPU"?? Apply same question to BPU+, ++,etc.... Next, approximately what 1/4 times do each classification run? I know driver, track, track prep, weather and how the poor sob holds him mouth all affect this but i just want ballparks. This is all just to help me out reading about your cars and also so i know what to expect when so and so pulls up in their Supra and says "yeah im BPU +++++++++++++ wanna go from a 70 bump?" Anywho you get the idea. Thanks. Peace.
