Fiber Tuned Intake Review with pictures

I got the tune all adjusted today and got some good logs from which I applied some very non-scientific math but atleast it yielded some positive results.
I moved my rev limiter up another 100 rpm to 7400 RPM. Once you hit about 6K RPM, you can really feel it start to charge and never lets up. I suspect that I could go to 7500 no problem but I dont like to spin my motor that high. Anyway, I dialed in the AFR and got some good data logging done with HPTuners. When you play back a log, you can see a time stamp down to a 1000th of a second. I compared today's logs vs some logs that I had from my last trip to the track. I just compared how long it took to go up 1000 RPM (6K to 7KRPM) in second gear. All my logs (after dialing in the tune) today were consistent to each other within a 100th of a second. They were also all .18-.20 sec faster than my log of a 10.42 pass that I was using for comparison. If this intake doesn't hurt my 60', I expect to drop atleast 2 tenths.

.18-.20 thats a lot for a one gear pull. that would be impressive to see anything over a .20 gain considering where you are at now. just so you know, i use to be a little freaked out about spinning my motor above 7200. but now shift my car at 7900. you will get use to it
Did you put a carb intake on it?

I'm glad to hear its pulling hard up top for you. I can't imagine any engine combo requiring more high end flow than this manifold can deliver.
As far as back to back testing, I'll see what I can do. My problem is I still have several manifolds to finish and deliver to customers that have pre-paid for them. And I need to incorparate these new features into them as well, because we sure can't afford to give UPS $300 per manifold like we did with this one, overnighting them back and forth across the country. We are working on them full-time, but they do require a lot of work for each one. I'll be caught up and maybe even have 1 or 2 'on the shelf' by mid Jan, unless of course we get many more orders.

Also, any chance your former tune was astray at all?
This is why dyno testing becomes so important....check both set-ups for proper A/F ratios etc., although no doubt what you have already collected looks promising. The other factor is how long were you running the toasty melted FAST?....Is any of that data from the obviously screwed up intake because now we arent comparing apples obviously.
Thanks!

Carlos...that seems like solid gains. Are we talking about what used to take 1 second....1.5 seconds....give us total time with both set-ups.

The car was tuned spot on with the hurt intake. The only thing that would have hurt performance with that intake would have been some turbulance in that runner. I run a MAF so a small leak at the seal wouldn't effect me too much as the MAP would correct fueling for the additional air (reduced vacuum). That cylinder was always lean but they say lean is mean so who knows.
The data that I compared was looking at a just under 2 second window of the 2nd gear pull. My car is geared for spray so I am going thru the traps at about 6350 on motor. So this intake will only really be helping me in 1st and 2nd gears on motor.

^^^There needs to be some kind of comparison done on the dyno, that is the reason we use dynos as a tuning tool. There are too many variables in this case to just go off of his tack times. IMO. They were talking about a FAST vs this dyno. Just wanted to know the status of this.

Loudmouth and 03Busa, you are both right. The chassis dyno is a great tool. But not so much with a big stalled auto like I have. The converter will actually behave differently depending on the power band which will be different between the 2 intakes. For this purpose I feel that the engine dyno would be the most accurate and unbiased comparison. It is also much easier to dial in the powerband on the engine dyno. It's just a more controlled environment where the IAT's, ECT's, Oil Temp, etc will all be pretty much the same. That and there is no cowl on the engine dyno 
.
The only reason that I would want to get on the chassis dyno would be to dial in my powerband and see where this thing pulls too on my car.
As for track times, sorry Busa but that's the only thing that really matters at the end of the day. And as I have said on several posts already, my car is deadly consistent on motor. It is literally as easy as pulling away from a green light in traffic to hook and launch. I WILL know if this thing works. The track opens this Wednesday and I'll be there. I was looking at the weather forecast and it shows rain but hopefully that will be in the early part of the day. If not, it'll be Friday.

Everytime a part comes out that everyone is very excited to see results on..always seems like you never get the ideal comparisons.
We have a fibertuned intake on the way that is getting bolted onto a 427" with AFR 235cc (tea ported) heads /w a ported Fast 90 right now...We will be posting a back to back comparison as soon as it gets here

Nitro Daves called today and they will be shipping our manifold thursday.
The 98 C5 it is going on runs 10.4 @ 130 n/a, very consistantly (transbrake 4l65e, 427" motor, 1.4x 60 fts on the motor. We've got a ton of dyno passes on 1100se eddy current mustang dyno with converter locked etc. We just touched up the tune and have fresh numbers with it and will put it back on as soon as the new intake goes on.
