Switching from Fast 92mm to MSD AirForce intake worth it? Currently I'm running a Fast 92mm (not ported) and I am considering buying an MSD AirForce to replace the Fast with. Pro's, Con's? I could also buy a Fast 102 as well. I'm just looking for opinions on which intake would work best with my current mods. Also, if I do swap intakes, I will be retuning in SD.

No one can really answer that question because I have seen no back to back testing against a FAST 92 or 102mm. They (MSD) claim power gains over competitor intakes, but the one test that was done isn't really enough to convince me because it wasn't done on a 346.

What phoenix said. The airforce showed gains on a H/C ls7 BUT specifics werent really released. I dont believe anything I see when a company teams up with ANOTHER company and has them "test" their product lol. There's a huge ddifference of the air demands of that engine vs a 346 with stock heads and a cam. Dont forget FAST is coming out with their new runners for the 102. If you get one of those and IF the msd design is better you can always buy the fast replacement runners that are similar to the msd ones.
You're missing out on about 10hp right now with the 92 vs 102 assuming you having a healthy cam setup. IF the msd one comes out and does show gains I'll just be swapping my runners on my 102. I kind of like that option because with 3 different runner types you can "tune" the fast to what you want

I do have high hopes for the MSD intake, but I would like to see some testing on a heads/cam 346 between the MSD and the FAST 102. That will be the deciding factor for most, as the pricing between the two is pretty much the same.

I believe, you will be able to buy FAST W/ choice of runners, your
Combo would run best W/ mid length runners at track/street without
Changing. Race runners for 7500+ RPM Combos will give up tons of
Low-end on street especially 6.0 and smaller. I don't think runners
Other then Longest will have CARB EO # for those that care, so
Unless originally purchased W/ long runners probably no EO#.
I have FAST 102 Ported by Tony Mamo, just decided to go LLSR
From CAMMOTION, so now patiently waiting for replacement runners
And having them ported also before having my engine built.
For your application my GUESS..., the FAST 102 W/ long runners
A little better on street than MSD, the Mid length a little better at
The track then MSD. Just a guess didn't see your cam specs.

Cam specs are 235/243 62X/62X 111LSA. Thanks for your input, The mid length runners are what I was looking at and that's why the question came up for the MSD intake. The MSD looks as if it uses a runner similar to the mid length Fast 102 runner.

New Intake I remember seeing a post on Youtube the tech. or the owner designed a manifold
that was for the LS engine. He flow tested in on his flow bench and his intake added a crap load of power. Now of course that was on a big motor. The X-Ram was the intake that Nelson designed in house. He explains that keeping the intake's runner should be as close to straight as possible. Look at the new MSD intake's runners. They kept them as straight as possible. I bet FAST will come out with something new to counter this MSD intake.
