Annnnnnnnd, the HC ruleset was largely cribbed from the IT Rules by Scott & Karl. Since HC was limited a single marque series, it was easy for them to open up the intake rule without a high risk of unintended consequences.

IT is a whole 'nother ball o' wax. Multiple marques and models... no way to open this rule up further without running the risk of needing to rebalance everything. Add on top of this the additional cost of all the current IT cars needing to test different length/design intake systems.

Oh, BTW, I know of several top running cars that are running short ram style intakes. There's waaaay more to a fast car than an intake
