Fiber-Tuned Intake Manifold L92 Dyno Numbers inside Here are the numbers on my GTO, I'm definetly happy with how it performed.
About the car:
Its a 402 w. L92 heads, and a mild cam. Its a A4 with a vig. (non locked)Unfortuently the car still has the stock airbox, and stock exhaust manifolds and stock exhaust. This is not the best test car for this manifold, but it sure shows that the manifold likes to rev.
The red line is a stock L76 manifold, it peaked at 6,000 RPM. I reved it up to 6700, but it certainly wasn't making any more power up there.
After switching to the Fiber Tuned manifold (The blue line)the car just kept reving. I picked up the rev limiter to 7,000, and it was still pulling uven up there. It looks like its time for me to invest in some headers, an airfilter and gears.
Also, we will also have flow numbers next week. Richard at WCCH, will be flowing them.
(They printed it out in MPH, because they kept loosing the tach signal)

As you know I am sure, the best comparison would be a completely modified motor with a FAST90 on top of it, replaced with your peice.
After all, that is usually the target market for a sheetmetal style manifold of that value. Otherwise the power lost in the lower RPM ranges on that graph wouldnt make up for the gains in the upper range. Which Im sure would be displayed better with a proper graph that had the RPM's marked.
This manifold has a huge market and has now given the L92 crowd a performance option, however It needs to be tested and advertised correctly. There's alot of clever guys on this board that will call out any thing that they might think is BS and I would really like to see this product do well, I think its an awesome design!
Look forward to further dyno testing!!

I'll have one probably in a week to put in my 402. 13.5 to 1 compression, big hydraulic cam, big headers, ET 240 heads, we'll see what it can do over a fast 90.
Only downfall will be that I'm testing it with a TH400 and a 4200 nitrous converter, with slicks on the car, so the dyno #'s won't be the impressive stick car #'s people see, but we will get a before and after on what it can do.

The only comparsion I will be posting on my build is before and after ported 90 fast with ported 90 mm tb to the new ported 92mm (95mm inlet) with 95 mm RevXtreme tb. That is if LG Motorsports does a pull with the old setup and then the new setup on the new 402? I'd be curious to see how well this new intake does VS the new ported 92mm FAST and Larger tb.

I am gonna talk to the shop today, see if I can get the car in on a Friday, make a pull and then get to changing the intake, and touch the tune up (leave the timing where it is, just adjust for the a/f to be the same) and make an after pull, so we have an accurate comparison.

That would be awesome. I think we're on the same page here and realize what is expected from a product like this. If it performs like I would expect it should, I will definitely get my hands on one.

With a converter that goes to 4200 on the brake, I could give a hoot what happens below there, hell 10 feet out I'm already up in the 5000+ rpm range for the rest of the run.
Ifi the peak shifts up that's fine as well, just puts it up in the power band more, which can't hurt.

I'd love nothing more then to pick up another 40 hp, that would be fantastic IMO. I get a 40 hp gain over an untouched fast 90, that's gonna put the car almost at the 500 rwhp # n/a, and will probably see a solid tenth and a half to 2 tenth's, and probably a couple mph, maybe more.

Just like you, I dont care what happens below 6000rpm honestly. Thats why Im anxious to see what it does over a fast90 above 7000rpm.

My converter flashes to 5800rpm off the line, and Ive got 520+rwhp n/a so thats why Im iffy on what another intake could be capable of. I dont want to get rid of what I got for something that wont give me any gains.

It will beat the Fast up above 7,000 by a good bit.
But every combo is going to be a little different.

I'm going to check out the picture when I get home. These work filters inhibit us from seeing images hosted on common sites. I've been looking forward to seeing some results out of this as I'm really interested in one of these for my Formula.
