You could just unhook your boost controller and run off the spring with each intake to measure airflow/boost loss. Then hook it back up to test at an even boost level. I think it would be interesting to compare the results from each set of data.

I got a mustang dyno locked in for this testing, but like I said it will take some time to do these swaps...time is limited. I may have to take a spring out of my gate to go as low as 10, but I can work it out.
Just need a fast manifold now.. Who's going to step up?
I got dibs on
Fast makes best power..
Pro-flow close second, maybe same peaks or more, but not best curve)

I agree and like it better than the Edelbrock pro-flow, but I don't think they make it for cathedral port heads yet? I honestly don't see either outperforming the Fast under the curve where it matters for our trucks though.

Alright so another issue im thinking of is, the size of the motor itself. 4.8's , & 5.3's are the small motors so would these intakes FAST, Vic jr., the Holley Hi-Ram, and what other intakes people are using still make decent numbers on these motors as the bigger cubed motors?

well thats what im saying i guess. The bigger motors gain more than a 4.8 and 5.3 would most likely so would one of these intake listed actually be worth the money switching to???

IMO the holley will be in the same range as the PRO FLO XT. FAST > vic jr... A fully ported single plane MAST (which is light and day better than a Vic Jr) was < 30 hp ahead of a FAST 102 (test mule was a 468ci IIRC).
If I am ever able to get back in the shop and put BRT back together, I'll likely be running a ported FAST (but maybe a non-ported one too), unless I can't move some parts and budget decides me...
