i have been sitting on this data for about a month now while waiting for everything to come togather for the dual intakes, we have the secondary pipes made, have a decent supply of the silicone y sections we had custom made and have a good supply of all the hoses and connections needed for the transition.

first off, the idea of the dual design was woody's (waldig). we spoke for some time about adding a secondary inlet to the cai kit. i was pessimistic to the benefits to the dual design at first and finally sent woody a secondary tube to play with last summer. he made it happen with a taadaa! hence the dual snorkle was born.

we had a run of custom made silicone Y sections made (took 8 months from when we ordered them) and finally have them here. made up a fixture for the flow bench to simulate the throttle body inlet and away we went with 4 hours of flowbench time...

SRT6 INTAKE FLOW NUMBERS
cai2 T big filters = 748.2 cfm @ 15in/h20
cai2 T no filters = 586.1
cai T big filter = 620.3
cai T small filter = 602.3
cai T no filter = 546.6
cai big filter = 602.7
cai small filter = 584.0
cai no filter = 539.2
oem intake system (stock filters) = 445.8
big filter (1) only bolted straight to flow bench (no tubing/couplers, think filter bolted straight to throttle body)= 782.6

cai2 = dual intake
t = teflon velocity coated inside and out
small filter = normal cai filter
big filter = xstream filter
no filter = entire cai system minus the filter at the end

notice larger filter picks up roughly 18cfm at that flow rate.
notice Teflon coating picks up another 18cfm also.
notice removing the filter hurts the airflow significantly.
Notice the dual inlet picks up 128cfm (possible with srt6 cai only, n/a’s would have issues with MAF sensors)

we have been getting a ton of emails/pm's this past week about the dual inlets due to the pictures that are surfacing of them and i will get everything for an introductory group buy for the retrofit kit togather later this week for those interested.

due to this flow data we have been eliminating powdercoating from our products and replacing it with the teflon coating due to the fantastic results we are seeing with it.
