I'll simply say the following:
I ran my personal best (12.3 @ 111.91mph) in 82° heat (1,700' D-A) with the Needswings single, 65mm EC pulley and a EC tune. Car was at full temp, so we can only assume some heat soak was present. I'm running a bone-stock coolant/intercooler setup. The 1/8th mile time was 7.90 @ 88.4mph... I also had over half a tank of gas (extra weight).
Recently I reinstalled the OEM airboxes and even went a step further by opening up the Y-pipe with a home made code-3 intake.
I did this purely for aesthetics, as I wanted to run the 32-AMG front engine cover for the car show season. No other change was made to the engine. Tires, wheels, all unchanged.
Fast-forward to last week:
On a historically faster track, with better prep, 1,900' D-A, a cool engine, ~3 gallons of gas in the tank, and 73° ambient temp -- the BEST I could muster was a 12.604 @ 110mph... 1/8th mile time was 8.134 at 87.12mph
So, it's safe to say the Needswings clearly flows much better than the OEM setup.
