That box looks great! Do you have any dyno information before and after the box was made and installed? How dose it mate with the clamshell? Are you also pulling more outside air in? And last are you going to build these to sell? Best, ROCKSTAR.

Thanks guys
At this stage it is a 1 off ,
whipple and 17 psi pulley was 764.7 rwhp@6500 and 663.1 rwtq @4950 @ 16.5 PSI on a dyno pack dyno this was with this air box as I built it when I fitted the whipple.sorry I don't have anything with the original air box.
This air box is shaped to fit the engine cover hense the foam seal. I have also enlarged the clamshell hole were it mates to the air box this was done after the dyno and I haven't been back on the dyno also the clamshell was up when I did the dyno run,
I am getting a new clamshell done in carbonfibre I may ask him to do an air box as well
also have just ordered the front nose,fenders,splitter and rear wing from Matech Concepts "GO BLUE"
PS this is a race car only so I don't have to worry it about being original,if it was my road car I would not go this far
:cheers

Airbox restrictions.
Gentlemen,
There is horsepower to be had here. Look at the tiny inlet in the photo below. The massive amounts of air pulled by big superchargers in the Ford GT must pass through two of these little square inlets. In addition, intake air must make a 90° turn from the clamshell before it gets to this inlet, make another 90° turn before the air filters, pass through two relatively small air filters, and then make another 90° turn before heading to the throttle body. While the current air box meets the styling, noise, and emissions requirements for a new motor vehicle, it certainly appears to be restrictive and inefficient to me. I can't wait until Kip does his flow bench analysis.

Neil your defenatly headed in the right direction. I personally think the inlet tube and maf sensor housing need to be bigger also, with more volume in the section where your filters go too. The Shelbys are using a 120mm mass air flow tube which is neer 5'' i believe. Those are also some great no:s at 17 lbs of boost. The way whipples, kennebells make the most power is with NO inlet restriction. The Gt has is made also cause it doesn't have to turn the air into the blower after the throttle body like the Gt500's do.
Nice work

"IF" I remember correctly (shudd up EP)....
there is a huge amount of science in the GT's air intake system that is addressed in the S.A.E technical papers issued for the GT engine development.
Not that improvements can't be made....

SAE Paper 2004-01-1252
Given all the constraints on the GT development (time, EPA, efficiency, etc.) the air flow characteristics of the induction system are quite sufficient for the 2.3 liter Lysholm screw type supercharger, even with the aftermarket FRPP Power Upgrade Power Pack's (M-2005-GT) smaller pulley and tuning, with perhaps an added support for the inlet tube. In fact, it seems to support the aftermarket Whipple Gen I & II superchargers for which it was not designed.
For those adding larger superchargers, the adequacy of the inlet air flow system should be determined by testing the flow required by the new system, and then design the throttle body, inlet tube, air box, filters, and air inlet ducting to meet the demands of the supercharger.
I find the design by the GT team to be totally adequate.

When is adequate enough?
When your wife or girlfriend tells you, you are adequate, how do you feel?
When you have dinner out, do you tell the chef his, or her meal was adequate?
I don't believe many on this forum strive to be adequate, if so they probably wouldn't own a FGT!
That said the stock air intake system is more than adequate for a motor in stock form. Modify it and some changes may be needed. I would like to see the data and look forward to Kip's report.
p.s. EP thought he drove his car adequately.

When you meet the goals established for the design.
At my age - I feel great. Couldn't ask for a better compliment.
Yep.
I have nothing against modifying, upgrading, and improving the performance of the car - ingenuity and development only improve the knowledge base for the vehicle. But, I do object to implications of inadequacy on the part of the design team, as I think they did a tremendous job in not only the design, but also getting it approved for all of us to be able to enjoy it.

I don't recall anyone saying that the design team didn't do a stellar job. IMO, the design team exceed my expectations! The engine and transaxle are very robust as proven by the many owners that have pump up the TQ and HP without any issues and without any major changes needed to either.

I couldn't agree more, the intake needs to be bigger,but at the moment I have both engine and trans cooler behind the air box so space is a problem until I get the new Matech front then I will move them to the front and I should be able to fit larger filters and intake tube running straighter.

Totally ****** Up
That is a neat solution and definitely gives me some ideas. Looking at the setup leads me to two immediate questions.
1) How much more surface area did you get with those K&N filters verses the stock filters?
2) With the exhaust directly under that setup, how do you keep the radiator and intake from using the hot air off the exhaust?

Ralphie,
Woahhh, I wouldn't go there. There aren't too many people on this planet who are more enamored with the Ford GT that I am. When I put Penske gas nitrogen coil overs on my car, designed by an original build team member by the way, I was not implying the inadequacy on the part of the original design team as regards the original suspension design. The original suspension had to take into account ride and handling, harshness, and cost constraints. If one is willing to spend some additional money, improvements can be made according to the original design team. When members install Whipple superchargers or Heffner twin turbo systems, they are certainly not implying inadequacy on the part of the original engine design team that had to take into account warrantee, safety, drivability, and a host of other considerations. Again, if one is willing to spend additional funds, improvements can be made.
As regards a less restrictive intake system, those same principles apply and they certainly don't indicate inadequacy on the part of the original design team. The Ford Motor Company's Ford Racing division markets less restrictive intake systems for a number of their cars including the GT500 that yield significant performance gains. Again, without the original equipment considerations of intake noise control, evaporative emissions, etc., and if one is willing to spend additional funds, there are improvements to be had.
Ford GT Forum members have made tremendous strides in all areas of this automobile. Superchargers, throttle bodies, shock absorbers, tires, shifters, coolers, you name it. As we seek to modify our cars and improve their performance we are certainly not slamming the original design team's work.
The one standout component that has yet to be addressed in our quest for better breathing, higher horsepower results, is the stock air box. Improvements in this area have yielded significant results in Ford's current supercar, the 2010 GT500, and I believe they will yield significant results for our cars as well. Let me also point out that, like Alex at T&A shocks, Kip Ewing is also an original design team member. He is not slamming his own work as inadequate when he states today that he thinks improvements in the air box could be made as well.
The Ford GT and the men who built it will never fail to "feel the love man"..... from this member! :biggrin

look at the pics in post #203 it shows the cold air box around the filters.
The coolers are feed cold air from the scoops on the clamshell
