A friend just installed one, picked up 10 HP on a 555rwhp car with a stock ls7 intake.
Cunningham motorsports on ls1tech installed one and got the 10 HP gain over a fast 102 but neither got the 30 thats been claimed..

Today we did a simple apples to apples comparision with a FAST 102 to a new MSD airforce intake manifold, on a c6 z06. We baseline dyno'ed and insured the Air fuel was correct with the fast 102, then installed the msd and did the same thing.
Car: 06 c6 z06
Mods:
CMS custom stage 3 cam (23x-25x on a 113)
WCCH stage 2 heads
FAST 102/ NW102 tb
ARH long tube headers with cats
stock rear section exhaust
DSX flex fuel sensor setup
FIC 725 cc injectors
Vararam intake
CMS custom flex fuel calibration
all runs done on e85, ethanol content of 76-78% throughout the day. we tried to keep coolant temp and IAT temps the same from run to run, in order to keep this test as legit as possible.
Fast 102/nw102 baseline:
553 RWHP and 510rwtq
MSD Airforce / NW102
562 rwhp 510 rwtq
conclusion:
After viewing the MSD airforce at sema last year, I could definitely see there were improvements over the fast 102 intake manifold. That being said, I knew in a factory style intake configuration, there wasn't going to be a huge gain without sacrificing power/tq down low and into the mid range. As you can see in the dyno sheet below, the msd does sacrifice a very slight bit down low and into the midrange, in exchange of a larger increase in power from 5000+ rpm on. In fact HP/TQ averages are slightly higher with the MSD unit. Now if the customer has an msd intake would I suggest upgrading to a msd? I would say its not worth the investment, however if he had a factory intake, I'd say move into the MSD versus the fast. In addition to the power gains, I like the fact that the msd utilizes the use of the production ls7 fuel and injectors. This means initial investment is less then the FAST unit, as the fast will require injector height adapters (or different length injectors) and a ls2/3 fuel rail (or aftermarket rails). I've also attached a text data sheet of both runs.

I don't know but the ratio here of hpxdollar is pretty low. not worth it IMO. You can have the oem ported for quite a bit less and possibly make the same gains considering that is was already a healthy engine.

I do, so long as you have mod;d the engine to the point that is needs the extra breathing room on a N/A engine (the Air force has slightly higher flow numbers that the Fast, and where the claim is coming from).
But again, on a Bone stock engine, still want to see the gains/loses of it (and even a Fast) over a stock intake. Hence what you are gaining top end (since the intake is going to out flow what the engine needs anyway), verse what you are giving up on the bottom end instead (since the intake is out flowing the needs of the motor).
If you are gaining 10hp at say 6K, but loosing 15hp at 2.5K, then the Air force and even the Fast have no merit for a stock motor (read GM spent a lot of time setting up the stock intakes so they pull hard all the way through the power band; so you don't have to play Rev ranger to get into the meat of the power instead).
P.S, would like to know the pressure that the manifold can withstand to, or if it going to a Fast problem child with high level's of boost instead.

Wegner is going to test one on a 416 like mine and it will be interesting to see Carl's numbers.

I agree, the new FAST runners look promising. At least for an LS7, I think FAST needs to redesign the entire intake. As it is now, the FAST is $250 more because the fuel lines will not fit. Even with the fuel line kit, I'm not crazy about using spacer under the injectors.
