[Andy@Livernois]

one can only hope... they were supposed to realease this last march however...

[MANOFSTEEL69]

That would look nice though...... :)

[Mike@NewEra]

The prototype has been done for about a month now , we should see these pretty soon .

[wreckwriter]

MSRP of $999... Would this use the stock throttle body or need a larger one? I'd be interested to see the difference between this one and a stocker aggressively ported.

[Mike@NewEra]

There is no way a stock ported ls3 intake manifold can compare to this .

[Andy@Livernois]

I am hopeful this thing lives up to the hype... The stock L76 intake licks...

[wreckwriter]

OK, so now we know your opinions of the stock manifold. Does it use the stock TB or is that another 999?

[wreckwriter]

Also it appears significantly taller than stock, will it still fit under our hoods? Will it use stock injectors or require larger? Any claims yet for gain numbers?

Maybe you guys don't know these things but I get the feeling you're familiar with the product.

If you read the sign on the side of the display, it talks about a 102mm TB. It does say that 90, 92 and the 102TB's will work with it.


Want, seriously, want.

[Blackdevil77]

I'm curious as to the gains of this. What would be the catch of getting this? Does it have any bad side effects on other parts of the car?

[Andy@Livernois]

It is supposed to use factory height injectors, and would fit under the stock hood... I wouldn't even begin to speculate HP numbers until we have one inhand to test... The best way to sum it up is this:

L92 heads flow 320+cfm out of the box, where the manifold barely flows 300...

As far as the throttle body goes it will indeed work with a stock one, but I heard an adapter will be needed...

[wreckwriter]

OK, thanks Andy!

It's all written on the sign/brochure.

Fits 90,92,102 mm TB's
14HP
11 TQ
Gain over a stock LS3 intake on an LS3 engine. (So expect less on a 6.0)
Retains all factory fitment and underhood clearances etc etc

[wreckwriter]

thanks. Hard for me to read that.

[Crazy Paul]

L92 heads flow 320+cfm out of the box, where the manifold barely flows 300.....

I just did some rough calculations.
@ 7kPa, valve lift 14mm (0.551"), Air temp 80F (26.6C)
The stock LS3 intake shows a flowrate of 305cuft/min

I don't know what pressure and temp they normally measure at.

[99-LS1-SS]

Does the L76 and the LS3 have the same heads?

[Crazy Paul]

Does the L76 and the LS3 have the same heads?

Only difference is the construction of the intake valves used.

pretty good improvement on a bone stock engine. Just imagine it on ported heads w/ a cam/headers/cai...

['02 ws6]

Lets see if they actually release it. The manifold market is pissing me off, STILL waiting for the Street Warrior and Edelbrocks new intakes for ls1's, hopefully FAST will also refer to their determined release date!

[99-LS1-SS]

$1,000 seems a little steep for 14 horsepower. If things go as planned I won't need that because there will be an air stuffer in its place.

remember that's 14 hp on a bone stock engine... not one with ported heads, a better cam, or anything else...

remember that's 14 hp on a bone stock LS3 engine ...... which has 12 cu/in more displacement, higher comp ratio, and a better cam than a stock 6.0 L76.

[99-LS1-SS]

I understand. I was just saying as far as "need" mods that would be after something like heads or a cam. I didn't mean to come off as a dick if I did.

[Blackdevil77]

I think i may be fine with a ported intake and TB. suits my needs better and my wallet

[Blown396]

Are they still gonna release this manifold?

[GRRRR8]

Its overkill. Many have made WAY over 500rwhp without it and why do I want a 102mm intake if I cant get 102mm drive-by-wire throttle body. Many cars upgrade to 90mm and thats what we have stock. I can see a need for it, but not on a stock cube G8.

[Blown396]

Cool, good valid points. Thanks for the info ;)

BTW, How is the project coming along?

So lets say if you stroke the engine...will this become useful?

Is there any stroker kits for us out yet? Not to get off-topic but was curious.

There are stroker kits available. Depending on how wild you go it could be useful. Still no TB option though.

They made all kinds of claims on the first one they did for the Gen 3 engines years ago and it didn't live up to the hype on most vehicles it was used on. I would sell them to people if they asked for them but never would make claims as to what they would pick up. Until people got to the huge cubic inches I never saw with my own eyes a big enough increase from the FAST vs an LS6 to justify it.

No trying to be shitty, but maybe you should take another look on the Gen III and dyno sections over on tech.

Those were early intakes. The designs were good, but the TBs stuck and the MAP sensor had leak issues. Now with the improved designs, there's no flaws, and the untouched FAST gets solid 20hp over ls6, and ported FASTs have gotten as much as 26rwhp, these are on stock cube cars with mild to aggressive H/C setups. I say the 102mm will net just as much as claimed and more on the bigger cube motors. FAST isn't SLP, as their advertised hp gains are legitimate, not inflated to boast sales.

I don't think you're trying to be shitty, quite the opposite in fact. You are just stating your particular case. As far as responses on most forums, I pay them no attention. This is the only forum I've ever found that was useful or accurate most of the times. I only rely on what I see from cars with my own eyes, and I still stick to my previous statement. I've always gone out of my way and out of my pocket to prove or disprove manufacturers claims on products when I can out of service to my customers. FAST is one of those manufacturers. At first I believed in them too since they worked in conjunction with wilson manifolds. But after the first couple of people came back stating no gains I looked into it. The only cars I ever saw that had even half the gains claimed were H&C cars w early LS1 intakes (EGR). Over the LS6 intake they were minimal. Yes on some of the big cubic inch cars gains were more substantial but they were turning way more RPM with alot more head and cam. The ones customer out of 30 who had a >20hp rwhp increase did multiple mods at once (headers, intake, throttle body, cold air, and tune). If some of the people on the boards gained that much power, good for them, but I don't think that the average person on here doing little mods should expect anywhere near those numbers.

[MANOFSTEEL69]

Well for now it's all speculation, opinion, and debate. So play nice :) Once someone actually has the product on their car, has it dyno'd and verifys the results we'll all know won't we?

[Ktlplxm]

---The engineers at FAST™ teamed up with the airflow specialists at RHS™ to develop a threepiece,
polymer intake manifold for rectangular port GM LS3/L92 engines. Testing on a stock
LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 14+ horsepower and
11ft/lbs of torque at the flywheel over the stock intake.---

As taken from the FAST site..
All they say is that it has that increase over a stock intake manifold; not over a stock intake manifold on a stock engine. It is doubtful they did the test with RHS on a stock engine, or even with stock heads. If we then take into account dyno numbers from a stock engine w the addition of larger, free-er flowing heads, w no tune then compare it to the same set up plus tune and new intake and throttle body, 14 hp at high rpm and 11ftlbs may be feasible.
I've been a FAST dealer for years, and yes they do produce some great products. Fortunately I have had the luxury of trying some of there products on my cars and having the option to return them or resale them to recoup my cost if it didn't hold up to my expectations or promised gains. I just figure with so many people pushing them, someone needs to play Devil's Advocate. As soon as one becomes available (and yes I have one on order) I'll do the testing and hope that I'm wrong about it.

haha We're playing nice!! Just comparing opinions lol

['02 ws6]

Agreed. Now in your case it may be worth 15-20hp but you've already made your stance on it. This won't be necessary for even the cammed GT crowds, as the stock ported intakes are sufficient in that matter. I'm thinking aggressive H/C setups and strokers will be the only ones that will actually utilize it to its full potential.

But in accordance to Charlie's new beef he has with new product releases and debating over them without first hand knowledge, I will just say I hope for the best as the aftermarket isn't real strong in the intake category.:)

And I see your point on the FAST 90, and I agree that the ealy models were pretty rough around the edges, but the newer design is one helluva intake, and proven. Price is still on the steep side, but there has yet to be another aftermarket intake to topple it $/hp. The Street Warrior was supposed to do just that,....but don't get me started on that thing, or its lack of appearance on the sales market.
