So as some of you know.. I figured I would do a little testing and see what results/gains some 3" intakes yield me. A few of my DE buddies have a 3.5-4" intake and saw really nice gains (yes, even with the stock throttle bodies), and were telling me I need to do this for the HR.
First off, here are the details on my car currently.
-2008 Base 6MT, 67k miles currently.
-Stillen Gen2 Intakes
-Berk Test Pipes
-Stillen Y Pipe
-Agency Power Single
-ACT HD Clutch
-ACT Streetlite Flywheel
-UpRev Tuned by CIN Motorsports (303whp and 272 ft lbs on their Mustang Dyno)
Here are some of the parts I am going to use:
Blox Filter with 3" V Stack, which will connect to a 3" silicone hose, which will connect to a 4-5" long aluminum pipe, which will connect to the 45 degree reducer to the throttle body. I am having the guys at CIN Motorsports fab me up the intake pipes. They'll be welding on a MAF slot and a small tube for the PCV system on each intake pipe. They will also be doing the tuning.
As for heatshields / airboxes, I am going to try and cut up the Stillen boxes to work with these, if they will not budge, I'll figure something out. I like the Takeda intake heatshield design where it seals when the hood closes... but my priority now is getting the intakes made, installed, and getting the car tuned.





Here is the difference in size of the filters.


andddd an idea of how much the stillen boxes will need to be modified for these big a$$ filters to fit

Sent CIN the pictures with measurements and everything, going to call them tomorrow and see if they will start on the intake pipes..

I plan on going with a 3.5 for my de, do you have any links or info on their gains?
But nice.i took a look threw your build thread, I take it this is going the route of full na? Or just seeing where it goes ?

Myself & the guys at @ CIN are firm believers that short rams WITH AN EFFICIENT AIR BOX OR HEAT SHIELD, outperform longtubes. Also the guys I mentioned earlier who had done the same with their DE, did shortram as well.
if you have the UpRev cable i'd be interested in seeing pre/post intake tempatures and HP/TQ results (if you plan on getting re-tuned)
i've been tempted to switching back to a short ram system when i get to tampa but i love my Injen long tubes (even if i have to remove the bumper to change filters
).

You gona rock the titek intake ducts with the tubes? And maybe using amsoil filters? I've heard nothing but good things. The ones with the recess on the front bit, like the Jim wolf filter, it adds something like 40% surface area.
Please do not cut into that beautiful V2 bumper!
