There is no way that a 2011+ mustang gt makes 430rwhp with a tune and cai! That dyno is inflating numbers big time! Once corrected it puts it at around 403rwhp which is normal.

You know how tuners like to inflate dyno numbers. A lot depends on the stock RWHP. I've talked to guys at the track and heard from the high 360s to low 380s.

I don't have a new 5.0, but I think CAI's are a good mod for every other Mustang before 2011. I don't know if I believe the HP gains, because what goes in has to come out. Maybe coupled w/a exhaust upgrade, the CAI will boost HP. What I've experienced with them over the years is that they improve throttle response. And, I understand getting a tune will improve throttle response too. But, maybe the new air boxes on the new 4v 5.0's are a much better design compared to past production setups?

I was very skeptical about CAI's in the past, but I proved it to myself by swapping mine out on two different occasions, during cold weather and warm weather. On both occasions I noticed an improvement in overall engine response.

Open Hood means **** to a closed air box. But means every thing to a open filter. And even at 40mph or 100mph with Hood closed it only pulls air from the one spot. Not the whole area of the Hood like when its open on dyno.

Yes but it's being pushed in, the cai has more air availability... So you're telling me two full bolt on cars, aside from a cai on one and all other things being constant, would be the exact same speed?

From test done yes. Full bolt on guys a crap load are still running stock air box. Because they seen no gains when doing real world unbiased test of cold airs. Some seen .05 of a gain when testing. Which I agree with them don't justify the 350 to spend on one. And some seen no.gains at all. Same exact times.

I agree with the "madness" comment. Anybody I have ever talked to that knows anything about mustangs, including me will tell you a good CAI with the right tune is the best bang for the buck out there short of N2O!

Actually the air duct is behind the fog light so unless you have a diff grille then the only air that it sucks in is just what's swirling around in front of you radiator.. Doesn't get "pushed" in..

It's not "ram air" but it's definitely more available than sitting on a dyno

So a grille might* increase hp, especially at highway speeds?

I guess that could be possible.. Maybe a hp or two.. The inlet tube is in the very far driver side corner of the grill behind the fog light.. If it wasn't blocked it should get cleaner cooler air.. Not saying it would help to those of you who are just waiting to pounce on me lol but it makes sense is all I'm saying..

I'll just remove the fog light, winning

Yep I have posted them before. Go to modularfords.com and into the 2011+ section. Lots of real world testing.

Yeah, and if you notice a lot of dyno vids have a big blower (fan) blowing straight into the grill when on the dyno.

It's either that or have hot *** air from the engine just marinating into the intake

Re: CAI & Tuner

To fix this issue on my old bmw, they made intake scoops to force more ''ram'' air affect on the open CAI...I think this would help the steeda design that has the lower intake tube. Intake grille scoop into Steeda CAI might show gains...just thinking.

Sounds like the perfect recipe for hydrolock

The intake scoops don't connect to the intake...far from it. Shouldn't be an issue with water if done right. The steeda CAI lower tube is on an upward plane...almost impossible water could go up tubing then get into the intake.

And if you are scared of hydrolock, they could devise a cap that blocks off the inlet area resulting back to a stock design when "needed"

That's almost impossible, unless you drive into a 3' deep puddle.
