anyone compared portwork on ported FAST intakes? i'm in the market for a ported FAST, and i know several sponsors have established themselves as excellent porters when it comes to these intakes, but i was just curious if anyone has compared one's work to another's?
has anyone flow-tested any ported FASTs? has anyone even been able to do a visual comparison? is there even a point, i mean, are all the port jobs comparable with minimal differences in power gains, or is there one or two that shine above the rest?
i ported my first FAST 90mm intake on my old LS1 HCI setup. i put in a Moser 9" at the same time and saw a gain of 24rwhp at peak with strong torque/hp gains across the whole rpm range vs. the LS6 intake/10-bolt numbers. obviously those are great gains, but do the professional porters gain more? i didn't think i did too extensive of a port-job on my intake. i mean, i took my time and was thorough, but i didn't have much experience to go off of and was trying not to hurt anything. did i get lucky and nail it on the first try or what? i know exactly what i did and can easily repeat my handywork on a new 92mm intake if need be, and i'm wondering if i should just do that or spend the coin on a Vengeance or Mamo or Formato ported intake.
anybody have any thoughts/experience/advice?
thanks,
ben

With few exceptions most of the port jobs done are a joke,nothing more than marketing and easy money for all the "expert" tooners.No one ever dyno's before and after porting so if there's a good gain they assume it's there magic port job.

...and you're basing this on what facts? who are the few exceptions?
I dynoed one as it was out of the box, then I knocked the ridge out at the end of the runner and re-dynoed it. I don't remember how it picked up across the board, but it made 4 rwhp more peak. Obviously I wouldn't consider that really porting one, but we've tested one other ported intake that made similar gains that were also already running an out of the box fast intake. I've never tried a mamo or formato....
Over the years, I've seen before and after dyno graphs, and seen people switching to the ported FASTs post better gains.
Take some time and search. Examples:

Probably a few in the dyno section or this forum as well.

my main question here i guess is this: since i gained ~24rwhp @ peak with my DIY port job through a 9", what would my gains have been if the 10-bolt were still in? just how parasitic is the 9"? both rear ends had 4.11's in them. i mean, if that 9" cost me 8-10rwhp, that means i should probably just buy a stock FAST intake and do all the porting myself and save a couple hundred bucks, SEVERAL hundred bucks in the case of the Mamo piece, albeit worth it. i'm just not sure if i want to spend all that time on another FAST and i like the convenience and peace of mind that comes with buying a professionally ported intake whose vendor is willing to stand by there work. that in itself is worth quite a premium. i, on the other hand, know what i'm doing, but at the same time i don't....if that makes sense. i didn't mess up my first 90mm intake so i don't really know what the limits are.

let me add to this: the portwork is pretty important here because it's going on a TFS245-headed 454LSX....i need all the extra flow i can get.

not really at this time, no. i was optomistic at first, but after the results posted on here, i decided it wasn't for me.
it's going to be a great piece when completed i'm sure, and i may even reconsider it, but i'm not going to wait for it. if i were building a FI motor, or planned on spinning it to 7500+ RPMs, then i'd almost have no choice, but that isn't the case. with the piston size and stroke length i have, i'd prefer not to spin much, if any, over 7200. in fact, i'd like to shift around 6800, but i don't know where power is going to peak so i can't say for sure.
either way, i can get a ported/painted FAST ready to rock out of the box for the same or less money than the Fiber-Tuned, and it's already a proven power maker. i can't imagine the redesigned Fiber-Tuned intake will make THAT much more power than a ported FAST on my setup, so i won't loose sleep over it.

If you did the 9" and FAST together, and still gained 24 HP, you must not be leaving much on the table with your port job. How was your mid range torque? That seems to be where the bigger gains occur. Look at this graph from LG and you can see they gained a lot below peak torque.

so i guess i did something right
i hate to think that the work i did on that intake was all that was necessary to see those kinds of gains. i mean, i put a lot of time into it - saturday and sunday afternoons, taking my time - but i didn't think i did anything remarkable. i could easily repeat my results on another intake...maybe i should go into business

you know, now that i think about it, i might be underestimating myself here. i mean, when i stop and think about it, i have a LOT more tools and experience at my disposal than the average enthusiast. i weld for a living, on high pressure/high heat vessels for power plants (i.e. feedwater heaters, MSR's, condensers, etc...) and i have a tool box in my garage with just about everything a man could want/need. my job requires me to do things like radius sharp edges, smooth transitions, and stuff of that nature to allow for more efficient flow and less wear on the unit...i just applied this knowledge/experience to the intake and used the arsenal of tools at my disposal to achieve my results. maybe i know more than i think 
I have seen a couple of FASTs that have been ported by the guys mentioned and I can tell you that Mamos port job was the most methodical and consistent from port to port. What this means in terms of power I can't say with absolute certainty as I haven't flowed or tested the different port jobs on any sort of equipment. His just looks like it was done by a machine.

ok cool, thank everyone. we've established Mamo's work is phenomenal. i was kind of under that impression already though...i like that he apparently takes pride in his work, but i just can't make myself spend that kinda money on something like port work. i've dumped a ton of cash into my car already, but it was mostly necessary.
i'd like to find someone who has done a comparison on different vendors' portwork, even if they were kept anonymous, i'd like to see them side by side and how they compared on a dyno and how they compared visually. i'm starting to put together that this hasn't happened. it MAY be something i try to do later on.
i just hate that i got such respectable gains from my own work without knowing how my old intake compared to the pros, AND how i've never seen a professionally ported FAST in person, much less two or more from different vendors side by side. i know when you cut corners trying to save money, you get what you pay for, but i don't think this is necessarily the case here when we're talking about the class of shops doing the work in question.
If anyone in the southwest missouri area wants to do a comparison, i'd like to throw something together. i don't have my car anywhere NEAR done yet, but hopefully will in 3-6 weeks....

We have seen and tested most of the ported intakes on the market. While there are a few that were somewhat "rough" most seemed to focus on the same areas and they seem to make similar power.
While porting a FAST manifold is not rocket science it is a good idea to go with a shop you can trust and that many others have positive results from the same product.
I feel our price is more than fair for the work we perform with all of the real world results to back the claims.
Best of luck. If we can help you out dont hesitate to give us a call. We currently have sale pricing thru the end of March.... 999.00 ported/shipped in the US.
