Yes - Our cars (SRT6) require more intake - even if running stock In my experience. With any added boost (177 - 181 - 185) your IAT increase and cooling them off is the most important performance "saving" mod you can do.
I say "saving" because a bigger HE and Pump won't add HP, just give you back what you lost due to heat soak and allow you to keep it. A must for racing and on hot and humid days. You should get the Johnson pump at the same time. You will already have the bumper off.
Call and ask to Erick about moving up to a 185mm pulley. Now that you have the idler and water pump pulley (that you won't need again) the upgrade may be inexpensive and you could sell that little pulley on EBAY and re-coup your $$.
Everyone benefits from with a bigger crank and a better Johnson.
** EDIT **
I want to add that the NW intake will provide all the air your SRT will need and will complement any pulley - - Stock to 185mm.
