Bonnevilles are known for low end torque, power right out of the hole, and passing as well, I want to up my power in that category. i don't know if they make aftermarket blow off valves for my year bonnie, maybe for series 1 and series 2 3800, but if they did yeah that would sound great and it would be funny, someone looking at a bonneville and then all the sudden hear the roar of a blow off valve, that would crack me up, especially for my year bonnie, decisions, decisions.
