I gotcha.

I believe polishing the inlet/smoothing the outlet like you mentioned would be the only thing to do...basically diminishing the imperfections from the factory, even though there are few to be had on that blower. Steigmeyer (or however you spell that), that ports the Cobra blowers...tried their funky outlet "rain drop" or tear shaped outlet...and it actually lost a decent amount of boost from it.
