There should be an optimum width but how to get that number??Another problem with too big a throttle body would be low air momentum causing loss of low end torque. Why? Let's picture this, same amount of WATER going thru small water hose and big water hose, which can shoot longer? Anyway, I could be wrong but no harm experiment if you got the part to try it out.</blockquote>
