FAST 92mm INTAKE PROBLEMS!! (NEED HELP ASAP)
One example of many...
TRak Cam only 99 SS w/Dynatech LT's, cats, LS6 intake, Whisper Lid with SLP dual/dual catback. 369RWHP through a Vig 3200 w/3.73 gears tuned to the hilt.
Same car, only change was UNPORTED FAST90/NW90 and re-tune, 399RWHP.

I can only comment what I saw myself and tunes myself, and I also did no expect that the modded LS6 behaves so differently. We did a lot of internal work as well to improve flow, but you can do only so much without completely cutting it up.
I wished the Street warrior would be out for comparison to the FAST. True, the FAST quality does not reflects its price, there are a lot of things which simply suck on that manifold.
BTW; I do have the TPIS intake with oval tb as well, even 350 USD is a lot for an afternoon of work.............

Go right between the FAST and the LS6 then. Get the BBk intake with the 85mm throttle opening and port the runners to your content. Throw a Summit 85mm throttle body on there (After porting it just like a stock one) and have at it.
Don't talk stupid...headers always showed gains no one ever claimed they
didn't. Do a search there are cars that made 430rwhp with LS6 intakes. Do another
search and see why there are so many people seeing little gains, and people asking if
the FAST is worth the money. If it is so good there wouldn't be anyone posting
questions about it. And when the manifold first came out most weren't seeing gains that
justify it's price PERIOD!! I dont have an agenda, and i'm not helping TPIS?? Thats bullshit to...i installed a TPIS manifold and it made a world of difference so how does that
hurt them??? I really don't care if you like it or not, i'm just sticking up for people who spend that kind of money for 10hp to 20hp. Drop their price?? They charge $350 for the upgraded LS6 intake you saying that's too expensive? And even before the FAST came out there were M6 cars making 430hp or more, so i don't where u get that info. from.

And you're not understanding I'm saying those numbers came from THAT dyno. You know every dyno is different right bud? You understand English? Because your little comment about it sounds like you have no clue what I even posted.
Now how are you going to get inside the BBK to port the runners? You can't. You can only port match. Which is NOT equal to porting.

Verdad Gallardo You are missing the point Now you're saying it gains 10-20hp over an LS6 intake. That's great. That's all someone with a maxed out car can typically expect. Where's the issue with that?

Why did you edit out your post about the header comment??? You made a wise *** comment that i didn't think headers worked. Thats why i responded in my last posted on your header comment. In other posted i stated that i was interested in the intake until i did a search and seen too many people questioning if it's worth the money for gain it makes. And it's not a matter if i can afford it, which i can, i'm just one of the many thats trying to justify the cost per horsepower, thats all. And i'm not your bud. And i never brought up anything about the BBK intake neither. And adding a few degrees of duration isn't going to change driveability that much either.
And this is the last post i'm making on this issue. 20rwhp is a great gain no doubt about that...but in my opinion ONLY is it cost alittle too much for that gain, and from a dyno that someone posted the other day the gains looked all peak, somewhere around 5,000rpm on up.

Let's clear this up, Bud
- I'll call you bud if I want and you can get over it or not since I don't mean it in a nice way but more of a derogatory way
- I never edited any headers comment. I don't even know what you're talking about.
- The BBK wasn't referring to you. It was another poster. Try reading the entire thread.
- The FAST is expensive, and of course people are going to question its gains vs. cost. That doesn't mean it's not a good intake and makes no gains. I don't even own one, but I can tell you it is a good purchase if you want the best since I've seen the results very clearly defined.
- Duration DOES trade low end for top end. "That much"? Depends. You can have more cam than you intake can flow (especially on an LS6 intake). Add too much duration and you lose across the board. I know, I've done it.

Since when does a FAST 78 not do any more than a LS6?
You buy based upon performance? Good. Here's a performance FACT for you:
On my tuner's dyno (very stingy dyno), there is a line between cars with a FAST and those without. Definite line. Those stock cubes with an LS6 don't break 430. Period. It just doesn't happen. Those that have done over 430rwhp have had a FAST. Pretty definite. Case closed. What's next? Headers don't help?
As for the cam swap, sure you could. And you'd lose ***** down low. Add the FAST and you don't lose it down low. No trade off there.
What's your agenda? Because you aren't helping TPIS one bit with this talk. If they want business, they need to drop the price of their LS6 intakes and TBs and get some out there.

Hey BUD and i dint mean that in a nice term neither, you DID mention headers in post #20. You quoted " What's next? Headers don't help" and now you're asking me were i got the header comment? And where u get the idea that u need a FAST to break 430hp...There's alot of cars making 430hp or more without a FAST. Oh i did forget one comment CASED CLOSED
RE-read man. I said on that stingy dyno. You DO know that every dyno reads different right? Some operators have very generous ones, and some leave them alone. Some are just generous while some are stingy. So no, ON THIS DYNO, they aren't breaking 430. Do you understand the words I am typing? Do you even know that every dyno reads different than the next?
Did you miss that I already saw where I said that about headers?
Do you work for TPIS, because you are KILLING their name by supporting them but having such an attitude.

Cased closed? I think you mean case closed. You didn't address the issue, since you can't read and comprehend. Case was closed when I laid out that defining line that you can't even grasp for some reason.
With the available carbide burrs that are longer than standard. And with the cartridge roll mandrels that are longer than standard. And with the flap wheel mandrels that are longer than standard. Then you can take the removable plate off the bottom and dress the radius at the opening of each runner and the long side radius/roof. The short side radius you will probably not be able to get to, I know I could not do it comfortably so I didn't try. But nearly as far as you can see up the port of mine is smooth.
Yes i get the fact that u are basing everything on a stingy dyno. But when u
use words like our motors with LS6 intakes dont make over 430 Period...it makes it
sound like you're talking about all dyno's not just your tuners..And i'm more interested in
what a FAST does on the track. I just have concerns spending a premium price on a part
that is recommended to be ported and that may leak under boost. And that comment about working for TPIS...I'm posting about what i've seen about it, and the fact it's not
expensive. I'm just standing up for a product that helps performance...isn't that what u are doing for FAST??

I never said period. Re-read. I said on that dyno. Which you can relate to about 475rwhp on a normal dyno.
I agree on track times making all the difference. Heck, I'll buy a FAST and if it picks up 0.2 NA, I'll be happy (although I'd like it to pick up 0.4).
There just aren't enough TPIS intakes floating around to get a good read on them. I'd get one too if I wasn't going with the better FAST. The runners make all the difference in the world. Especially on my car, but even on stock cubes.
