[QUOTE="spanky250, post: 164416, member: 20897"] Don't confuse response with power. You can have a very responsive engine with little power, or you can also have a very powerful engine with poor throttle response. Ideally, an engine will have the best of both, but in the real world, a large part of engine tuning is finding the best compromise between the two. As BRush stated, the divider plate will improve the low-end response, and allow the engine to pull into the meat of the power more cleanly, but there is only a modest increase in power. Increasing the horsepower output of an engine requires that you increase the amount of fuel-air mix that flows through the engine, and is burned, at a given rpm in a given amount of time. All the divider plate does is shorten the amount of time between opening the throttle and the fresh fuel being drawn through the jets and into the engine, because the smaller effective intake tract at below-the-plate throttle openings helps to increase the velocity of the intake charge beyond what it would be if it were flowing through the larger, unobstructed intake tract. In simple terms, the same amount of fuel-air mix flows through a smaller intake tract, so it flows faster. The end result is a slight improvement in response time and volumetric efficiency. [/QUOTE]
