True story, for anyone chasing a number i can honestly say goodluck! For those who are still in the same boat floating **** creek without paddles scratching their heads because we have been mislead once again it sucks... I hope someone can figure something out. Should of gained something from the swap, not a negative report and second maybe that baby cam wasn't big enough? I want to see this intake perfom with a cam as big as mine is.

The real numbers that counts is at the track! A Dyno is a turning tool! If your going to dyno it. Put it on the dyno do a pull never take off the dyno then install intake and do another dyno run and then tuned it on the dyno! That is the only 100% to get real numbers!If you dont do that its pointless. I have had a friend add a part then get it dyno tuned and say oh it made like 10 less hp then b4 but picked up a tenth and 2mph at the track 
FAST 92 is being discontinued
make way for FAST 102, all FAST 90/92mm cable throttle bodies are compatible

My friend just finished swapping his l76 manifold for a fast 103mm ls3 version..he has a small cam and bolts on's..he gained 23hp and 13 tq for non believers look at the g8board and under search type in fast 102mm he dyno results and pics plus video..it works so let's stop the bull

So true. It's called stop being a cheap *** and buy the intake and TB as they were designed to work together.... 30hp loss with a intake=not possible. This is a great site but lame product evaluations like this one need to stop. If you plan on doing a comparison make it a bit more thorough thank you very much.

Post #29 he states "I have 403hp with my set up and its great."
So when he gets to the shop they do a baseline he falls to 392 hp with the intake swap, then tries to use all of the supposed gain as the intake making the power.
So if we really do the math he gained 12 hp after a $900 intake, $250 porting plus the labor to install ($200) and the price of the tune ($450).
Not a bad deal, $1800 = $150 per horsepower, sweet!!

I too don't subscribe to the loss of 30hp with the intake. And I think it is common knowledge the FAST 102 is an improvement over a STOCK L76 or LS3 intake. Put comparing it with a ported stocker, the gains IMHO, are not worth the money spent.

his first pull was 392 with stock manifold first of all..second with the swap of the fast lsxr and third with tune and fast lsxr he gained 23hp and 13tq you did not see the chart??I doubt the port work did any help mayb 2hp at that..why can't u just justify that he gained power Ina stock 364CI ???for a swap of intakes Thats was a pretty good gain..and where U see 1800 bucks these manifold can be had for 700 some places the spacers is 30bucks and porting if that 200..mayb 1k but he gained power I will post my results also as I have ported heads/full exhaust/bigger cam..Ima stop this he say she say for good..I have a ported "l76 manifold so I know what the gain will be after my swap I netted 460hp 430tq on a dynojet224 and 441hp 406tq mustang 1100 dyno CORRECTED!!!u should see a increase in my case i will post sheets video install progress to end this hype..A company won't sell a product that loses power...I pretty sure if they did they will be out of business and all the f bodie on this Baird won't be running the 90/92/102 intake and throttle bodys!!!
The prices are the prices, IF he got a deal on the intake, fine. HE said $250 for porting I believe, was labor free? doubt it, he said he doesn't work on his car, even 2 hours labor is $160-$200. Was the tune free, probably not, if dyno and street tuned minimum is $450. So, knock off $200 for a deal on the intake, still about $1600.
This G8 would be only 364 ci engine that has shown that type of gain on any of the forums, from any builder/tuner, on any car.
If you read the post, he said he had 403 hp on a prior dyno pull. Were did the 11 hp go that is now being counted as a gain. A 10 hp gain on a cammed car is very probable, 23, probably not.
I believe they will work on the bigger engines to get them more air but it doesn't matter to me. I hope your setup shows a worthwhile gain. Good Luck.
I have a ported "l76 manifold so I know what the gain will be after my swap I netted 460hp 430tq on a dynojet224 and 441hp 406tq mustang 1100 dyno CORRECTED!!!u should see a increase in my case i will post sheets video install progress to end this hype..A company won't sell a product that loses power...I pretty sure if they did they will be out of business and all the f bodie on this Baird won't be running the 90/92/102 intake and throttle bodys!!!
And yes the FAST 90's and 92's have done really well and have definitely been worth the money. The 102 for L92/LS3 heads was talked about for years (long before the G8 came out so you probably wouldn't know this) and the "release date" kept getting pushed back and back. Why do you think that was?
I wish you luck. Nothing would make me happier than you to bolt this intake and tb on and pick up 30rwhp.

If you look at it like that your never going to make your motors max potential
yup your right for most people! You have a lot people that pay $1,000-$1,300 just for some stainless 1&7/8's headers and then $400-$600 for a catback. So are we going to talk crap about most of the people that want their motors max potential because we were cheap and have pacesetter? No
r
I have $300 in my pacesetter LT new and $100 in my TSP y-pipe and a free 3" magnaflow bullet with turndown. I only have $400 in mine total. If i wouldnt of found deals on what i have and had the $ i would have some AR stainless 1&7/8's headers. I would spend $1,300 just to make for 5-8hp over my pacesetters lol
You can't get in deep enough to get a good full port on l76. Fast you can take apart and do a 100% full port.
This from someone thats not a FAST fan due to the price on a plastic intake! But if you want max poetical you have to get it. My car will have some truck manifold and vic jr so i would have to worried about a FAST intake or what headers i have.

Cobrakiller and I have talked at a QT before. He has a sweet ride.
But like stated above, you #'s are skewed. In his thread he states he has made 403/360 pre-FAST intake.
So what happened here is the stock manifold was taken off, and the FAST bolted on and dynoed. It was not tuned for the FAST which is why the car actually lost power when compared to his previous best dyno #'s.
So after tuning was done he made 415/357. So he gained 12 peak rwhp and lost 2 peak rwtq.
And for the record, CK had a stock intake. He would have seen no gain, and maybe even lost some, if he had of compared a properly ported L76 to the FAST.

I've seen people gain ligitmately 20rwhp, FAST LS3 102, NW 102 DBW TB. This was on 402ci with stock untouched
LS3 intake.
Even had one customer, install the intake (LSXR LS3), gain 10 rwhp, install the TB gained total of 19rwhp overall, using same dyno.
porting hasn't shown big gains on LSXR intakes

Damn right I look at it like that..lol
I have what I like to consider a budget build..I'm in it within the means of the budget I have..and it's a decent budget, but not up there like some people here have.
Yea if I was going all-out for money I would get the best of the best, but I'm in it for fun and to enjoy my car. I honestly couldn't pay $1000 for the piece of plastic that gets 20 more hp over the stock peice that cost me $225.
To me that is all it is, a piece of plastic. I have a black piece of plastic on mine known as the L76 that is working fine.
That difference in $775 there paid for my new-in-box Heads, Valves, Offset Rockers, and Pedistals, with some left over. Like I said, budget build.
I'm happy with what I have, and for the work I put into it, it performs well.
