redrocket1985 Posted March 29, 2014 Report Share Posted March 29, 2014 The stock filter looks pretty much like a cold air intake. Anyone have any proof/personal experience that a cai on these cars actually helps over stock? Quote Link to comment Share on other sites More sharing options...
Inertech Posted March 29, 2014 Report Share Posted March 29, 2014 Well it is a cold air intake. I don't see the need for an aftermarket really. I'd be curious also if anybody had seen any real difference. Quote Link to comment Share on other sites More sharing options...
1 Alibi 2 Posted March 29, 2014 Report Share Posted March 29, 2014 (edited) The below text is from a thread on the SVTP site, may or may not answer your question. The test car already had an upgraded blower & CAI. ( 123mm ) . . JDM Super Cobra Jet 140mm Cold Air vs. 123mm Cold Air -------------------------------------------------------------------------------- We installed the 140mm Super Cobra Jet cold air intake today on a customers 2010 GT500 2.9L Whipple car and got some awesome results! The fitment on the 2.9L Whipple requires trimming the SCJ inlet tube 1" shorter than with a 3.4L, 4.0L, or 4.5L blower. This is the first fitment we have done on the 2.9L car so we are happy we found out before we sent this out to one of our customers! We will include fitment instructions for anyone who purchases this in the future. The power gains were surprising to say the least as we netted over 35 RWHP and nearly 40 TQ!!! Showing there is some restriction, at least with a car moving this much air. The car in prior testing had the Whipple 123mm CAI. We replaced this with the SCJ 140mm air intake and fitted a 07-09 Ford Racing Air box for a heat shield. This required some cutting and making a spacer to attach it to the factory radiator shroud to secure it. Overall I think it came out looking awesome, and performing way better than we anticipated. The more important benefit of this SCJ 140mm Air intake is that is lowered the mass air reading down to a much safer range and allows us to make a whole bunch more power when we turn up the boost and dump in some race gas!

Bookwyrm Posted March 30, 2014 Report Share Posted March 30, 2014 The stock air filter is already part of a cold air intake. Replacing it with larger/higher flow CAI units (or even just replacing the stock paper filter) has definitely shown real performance gains, for a fairly modest investment. The more cool air you can get to the intake, the more oxygen is available in the combustion chamber (because cooler air is more dense) and the more efficient the engine will run. This is doubly important with a supercharger since it's pressurizing the air even further. That's basic thermo-dynamics. Ford did a pretty good job on the stock CAI, but they also were optimizing for cost so it's not as good as it could be, especially as your engine gets heat-soaked. They also stuck that pesky resonator in it, which robs us of some of the lovely supercharger whine... Quote Link to comment Share on other sites More sharing options...

You can gut the resonator with some basic hand tools & save the cost ( $ 69 ) of a resonator delete tube. Quote Link to comment Share on other sites More sharing options...
Competition Posted April 4, 2014 Report Share Posted April 4, 2014 I've read about some good gains with the JLT stuff, so I decided against wasting time with the delete, and just do it once and do it right with a JLT setup from Van at Revan Racing.

Geneo4116 Posted April 4, 2014 Report Share Posted April 4, 2014 MVP did a video where they changed it put to a jlt carbon fiber,only gained 6 hp,not wotrth it Quote Link to comment Share on other sites More sharing options...
Competition Posted April 4, 2014 Report Share Posted April 4, 2014 MVP did a video where they changed it put to a jlt carbon fiber,only gained 6 hp,not wotrth it Revan Racing has a dyno video showing a 18rwhp gain from a intake alone. I'll try to find it. Quote Link to comment Share on other sites More sharing options...
tomshep Posted April 5, 2014 Report Share Posted April 5, 2014 I did the resonator delete and airaid filter. The delete cleaned up the intake tract from a visual stance and makes the builder plate more visible. The filter for performance and maintenance.
