Ls7 Fast 102 vs MSD airforce comparison
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 fast 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.

thanks,
I was curious about product advancement when I saw an ad, even though I am not in need of the part. Really think the ability to open the thing up for porting and clean up is a nice feature. With a plastic part in two halves, this work should be easy for a guy with a power tool.
The ads I saw didn't play up that this part has "atomic air force" twice, on a big raised tag on top. I could play the predictable old man card and say this name sounds like it is for the eighth grade market, but I don't think eighth graders are big souped up manifold consumers. Obviously, there is a lot about manifold naming I don't understand.
Plus I know that the atomic air force name will soon be branded on a chrome "jake" skull and featured here by the proud owner. So many old man cards in the deck........

Thanks for sharing, did you happen to measure the height difference between them?
