Which is why impeller modifications and pulley changes should both be against the rules. This is not rocket science, other sanctioning bodies have been running limited power adder rules for years. Blowers should be required to be as produced, along with mandated pulley sizes. Trying to mandate boost is a lost cause. With everything else being the same power adder wise, what if one guy figures out a way to turn more rpms? Boost increases. Less restriction, boost lowers, but power increases. Mandate the pulley size and power adder modifications, and hp increases are earned just like any other engine.
