Josh@Dynospeed Racing spent some time testing intakes on the dyno last night with his car which is modded like many cars on here:
2011 ctsv A6
Forged LSA 6.2, stock block and stock crank
Trickflow 255's out of the box
Ported supercharger 102mm
Stage 2 camshaft
2.5/8.6 pulley combo
American racing 1 7/8, off road x pipe, stock axle back
ID 850
Dynospeed heat exchanger
Jabsco pump
NorCal ice box
Nitrous express
Stand alone fuel cell
All testing was done on the same day, May 1, 2014 in Memphis TN. There were no changes to timing and all testing done on the same tank of gasoline. Only the MAF was rescaled when changing intake size and TB parameters changed when increasing TB size.
We tested the car baseline with a Mamo ported LS7 TB and a popular 4" intake with 12 inch filter (blue line on graphs 647/565).
Next was the Mamo ported LS7 TB and the new 4.5" inch Dynospeed Racing intake (red line on graphs 662/601).
Finally was the NW 102 TB and the new 4.5" Dynospeed Racing intake (green line on graphs 689/627).

It picked up 18/36 at the rear wheel just switching from the 4" to 4.5" intake with the same Mamo LS7 TB.
Since most who switch from the stock style TB to the 102 upgrade their intake at the same time, we made a graph of the Mamo ported LS7 TB with 4" intake (blue line) vs the NW 102 with 4.5" Dynospeed Racing intake (green line):

It picked up 42/62 at the rear wheel going from the Mamo LS7 with 4" to NW 102 with 4.5" Dynospeed intake
I'll say, we're pretty stoked about the results.
