Something for you new 2011 owners to think about.....

[470 GT/CS]

Thanks, some people on another forum that I posted this on wanted to know.

Within their engineering and budgetary restraints. The aftermarket is not constrained by interior noise limitations or bean counters.

Interior noise limitations? You do realize they have been putting a tube from the intake to the passenger compartment for a few years now to raise the level of noise right? Ford also puts a pretty kick ass intake on the 2010-2011 GT500 with an open filter element and everything so I would say they are pretty capable of developing a good intake. (FWIW Our 06GT Auto runs 13.0's with a tune, 4:10 gears and stock CAI/filter)

I do understand what your trying to say but it would be more appropriate to say that Ford is more limited by other influences then the ones you stated. The biggest one is the EPA and the shed test the car has to pass. Latent HC's are measured literally in a shed that the car is put into and a certain level is acceptable due to plastics curing etc.... but the intake, which is the quickest way for HC's to escape out of a freshly shutoff engine, has to be designed to keep that from happening. (remember the HC filter in the 05's intake?)

I look forward to seeing what C&L and other companies come out with for the new 2011 and will test as many of them as possible on our 2011 GT and I will provide unbiased opinions and real results.

A few years? In Mustangs? I only seem to remember for one year.

Definitly a huge difference in airflow with the C&L. The question is how much extra cfm do you need? At 28in the 2011 is flowing about 750 cfm. Will a stock motor pick up from an extra 400+ cfm? I guess we will find out

Back in the dark ages (mid-'80's) I got my AAS degree in fixing cars. Part of the degree had to do with airflow in engines. If I remember right, the instructor made a big deal out of 'over-carbing' engines. As in, small blocks didn't need more than a 750CFM carb as they don't flow that much air anyway...

A quick poke around with a search engine came up with this:

http://www.speedwaybids.com/calcs/powerfromcfm.html

In the end, a specific CFM number is no good without qualifying what standard was used, i.e. temps, pressure, etc.

I really find it hard to believe Ford would make what appears to be a world-class engine just to stifle it with an crappy airbox/filter setup. So until we get dyno/drag strip proof on tuned stock airbox/CAI setups, we are all just armchair racing...

If you ask me, I think Ford is doing the most inovative work right now. Think of the monumental task of beating GM at the power game, yet making the engines robust enough to put up with what I lovingly call 'redneck-abuse.' You know, cold starts taken right to redline, changing the oil once a year whether it needs it or not, etc. To make these engines survive that abuse and still come close to 1hp/liter is pretty spiffy in my book...

i agree 100%

SD I have to agree with the few, I think that the ford combo is well balance and nearly tapped out, the one immediate gain that i can see from this car will simply be the addition of octane and a few degrees of spark. I have a feeling this thing is gonna be a bit tapped out, I am aware that everyone in the industry will be on this thing like a wet blanket (like myself) but it seems that ford left little on the table, the HP war of the big three really forced Fords hand with the new combo.

 

[kyoshosp2]

well i know the Forged Rods we already have out may wk, but someone needs to make a piston for this motor fast, cause this thing is screaming for some BOOOOOOOOOOOOOOOOOOOOOOst

Ok, we know that the 5.0 will demand more air than the 4.6 just based on displacement, factor in the heads and intake manifold, it definitely demands more air especially in the 5500-7000 rpm range. Now, if the factory 4.6 air intake flows better than the factory 5.0 air intake, and the 4.6 picks up 10-15 hp with something like the C&L Racer, why wouldn't the 5.0 pick up, at the very least, the same power with it being equipped with a more restrictive intake stock? With tuning aside, the 5.0 may be close to maxed, but CNC work to the heads, more compression (or less for boost), more aggressive cams, etc is still left on the table for the after market.

 

[Mike@PowerHouse]

Alot of the power would be picked up with the additional timing that is tied in with the CAI tunes. There is no doubt that the CAI do pick up SOME power.
Ford had an uphill battle in light of the new HP war. the advertised power is actually on 91 octane and the 5.0 makes like 390 with 87.
That tells me that the car is pretty well tapped out, I have to think that they did the math on the airbox. If they could have gotten another 5hp with another intake design, they would have.

The only thing left to compromise to get more hp is emissions.......

 

[dragpac]

off road x-pipe should help alot

 

[dagamore]

as others have said, if the motor only needs X amount of CFPM of air flow, to make the power they want/need out of it and as long as the stock intake/heads can flow =>X then there is no restriction right?
