I know is the same box but in CF.... Anyway the other intakes don't work, just for looks & some of them take power away from the car...

Correct me if Im wrong, but issnt the intake on our cars designed to grab air while the car is at speed? With the car moving at 60mph+, I would be willing to bet the stock box (or good, sealed aftermarket box) will show positive intake pressure. Obviously this would make it much more tricky to construct a meaningful test of performance. But just strapping on some open element filters while on a dyno doesn't, in my opinion, offer complete testing. That being said, kudos to AMS for taking their time to forward this platform!

This is Joe@ Fabspeed Motorsports USA. Since my company and its products were mentioned in this post I have a right to respond.
1st I had the very 1st 997 TT that I bought way back in the summer of 2006. I designed and perfected the headers and exhaust for these cars in 2.5" and 70mm 2.75". We employ HJS catalytic converters and build everything right here so I know these cars inside and out. This was over 7 years ago.
I Dyno developed a high performance dual conical air-intake for the 997TT after several iterations and the Fabspeed 997TT intake system that is on my website works exactly as posted.
Fabspeed used a DYNO jet with an automated weather station and the rseults have NO correction factors. In other words we did NOT mess with the results.
The system that you made AMS shows the conical airfilters sitting right above the exhaust outlet pipe on that silver Twin Turbo car. You have 2 issues right there. #1 the intake pipe track is 200 to 300% longer than stock and #2 the intake pipes are placed RIGHT above the exhaust outlets. That silver TT car is sucking up spent exhaust with artifically long intake tubes that could not work under any circumstances.
As far as Porsche 997TT airboxes- Fabspeed systems makes power and best of all amazing sound as you downshift and upshift. The Fabspeed Motorsports air intake system allows the car to make mild blow off exhaling noises that are really cool versus NO sound with any stock OEM airbox.
Try it Im telling the truth. I have had each and every Porsche Twin Turbo from 993 TT, 996TT, 997TT, 997.2TT, Cayenne TT S,, Panamera Twin Turbo, GT2RS and I have a new 991TT pre-ordered.
If it does not make power and sports car sound I will NOT release and sell the product. I will soon install the Dyno test the 997 TT Fabspeed air intake on a 750HP+ GT2RS

The fans that we have moving over the car are massive. I'm talking so large that if the rear bay door is shut you cannot even open the door that leads into the dyno room from the pressure built up in the room. There is simply no way the intakes are sucking up exhaust under WOT.
I really dont understand how the length of the pipe has to do with anything. We use that pipe specifically as it was much larger than anything anyone could even use. Also we wanted to remove it from the hot engine bay so it could get the ambient air from the dyno room fans.
Maybe your intakes are different but if they are open element filters without a properly sealed box I don't see how. With that being said we are not above being proved wrong. We would be willing to test your setup if you were interested. If they do indeed make the power you claim we will not only post about it but we would be happy recommending them to customers in the future.

I bought the air intake and I had it in my car for 2 weeks, i really like the "exhaling noises" but It's very painful to see all the hot air going in the engine, the Carbon fiber shield doesn't do anything at all.
I actually felt a BIG lose of power but I can be 100/ sure because I never dynno my car.
I also had the exhaust version 2 in my car and you are right there is 0 drone but the car sounds like a Honda Civic from 1994.
I had 3 different air filter in my car from $230 up to $3500 THEY DON'T DO ANYTHING...
I'm sorry to hurt your feeling but mine were hurt after I spend all that money for nothing...

Hi Joe,
Just so we're clear we didn't mention anything about your intake system at all, I was just doing a comparison of what I thought was an ideal intake to the stock factory intake box. Somebody else mentioned different brands of intake systems.
Again if you want to send us a Fabspeed intake to test I will test it under conditions approved by you. I have nothing bad to say at all about any of your products.
Our test was done back to back, nothing else changed and within an hour of each other (car never was unstrapped) The SAE correction factor was 1.03 on all the runs.
We used a smooth bore 3" AL mandrel bent tube going into large air filters, the extra length using the very mild bend is more ideal than anything that can be placed in the factory airbox space. Length would have no bearing on power at all, the only time you would have significant pipe flow loss is if you had many sharp bends and a lot of tubing (we're taking 20+ feet).
http://www.efunda.com/formulae/fluid...ction.cfm#calc
crunching all the numbers for 150 m/s of airflow speed which is over estimated by a lot (that's about 100 lbs/min of airflow per intake tube!), the difference between 4 feet of 3" smooth tubing and 1 foot of 3" smooth tubing is 0.0056 psi pressure drop... relative to horsepower, that would be zero difference.
We tested the factory airbox with the trunk lid open, so if that cold air intake was sucking in any exhaust gas, the factory airbox would have been doing the same, if not worse because of the hot engine bay.
We don't just use barn fans in the dyno room, we have $20K worth of fans and ducting to simulate high speed driving. Two giant high velocity fans in front of the car with ducting (10 HP 3 phase motors), if you turn them on with the doors closed the pressure-rise pops your ears and you can't even open a door. The amount of airflow going around the car and out would draw all if not most of the exhaust gas behind the car.
Again, nothing against your products Joe, I'm just posting a real life test of what we've done here with our own setups.
If you have something that works well let us try it out and we'll be happy to start selling them.

Guys, the purpose of this thread wasn't to bash other vendors or leave a door open for people to start putting down other products.
These are the real life tests that we did and use the information to help you make your own decisions. Unless there are true tests done back to back with other systems it's really not fair to say one system is losing horsepower or another is gaining just by feel.
I have tested one back to back for a customer (on his car and while the car was strapped on the dyno) and we gained almost 30whp going to the stock airbox. It was not the Fabspeed one for the record, but another vendors intake. I believe he posted the results here on 6speed so you guys can find that info

Regardless. The data is useful, thanks for going through the effort of doing it.

I know you guys said your not running E85 with the kit because the quality in the area, but if a customer wanted it for there car (saying its better in there area) is it a possibility? Can you tune for E85 with this kit? Do you sell a fuel system that can support the E85?
