FAST LSxr 102mm intake showed up today!

[1320junkie]

I was out at MTI this morning and they were talking about it..basically they were saying the more radical the cam the better response from the Fast Intake...dont quote me on this as i was in awe looking all of the stufff they had going on in the shop

If it actually does make a difference with a cam I wouldnt mind, it's one of the things I want to do to the car along with ported heads, but I want to go down to dallas to have ADM do it.

FAST is working on some updates.
This manifold was fully designed and in production before the Camaro was released.
Some of these issues are already covered in the Instruction Sheet.
There will be a Q&A/FAQ release very shortly.

[alex33x]

Updates are welcome, but that wont help all of us who already bought and have the intake installed unless they do exchanges.

so with a cam is the 102mm fast intake manifold worth it? i found one for less than $800

[2010_5thgen]

and for 800 its probably not worth it.

sure does look good when you get the heater hoses re-routed and the vacuum lines ran under it:

Well, from the Gen3 Hemi stuff, the 5.7 has this crappy looking plastic intake and the 6.1 has a really nice looking cast aluminum intake with larger/shorter runners and works well on the 6.1s

The 6.1 intakes suck on the 5.7's the ports size kills the intake charge velocities, you loose low end and don't make enough up on the top end to make up for the low end loss. It seems the Hemis really like port speeds ( our Street Strip heads are seeing 340cfm @ 28inchs at .500 as I recall on my heads ).

We have stock 80mm TB's and we don't see a gain on the 90's unless you are running a HUGE cam or spinning the motor to the upper end.

We don't really see gains on TBs until we are in the 392 to 440ci motors.

One thing you all have us beat on is being able to spin the motors higher, we are stuck at 6800 even one our built motors. we still have Valve spring issues and computer issues going beyond that in the Auto cars.

I just cant see getting all that much from a "fairly" stock motor with a 102mm TB bs say an 85 or 90.

Looks better painted and the MAP relocated to the back of the LSXR as seen on our Katech/Halltech E85 Ethanol Super Bee Package shown here:

Halltech's Carbon fiber Super Beehive with the Halltech Killer Bee Ram Air Induction. 429 with 13:1 compression ratio and 675 HP/620 lbs-ft torque. The LSXR and 102mm Billet throttle body.

WOW, Jim that looks fantastic!

FAST is working on a LSXR FAQ. They should have it at SEMA. I'll post a copy when I get it.

I don't believe that any of the LSXR manifolds are considered a "Stock replacement". They are to support more flow with cams, heads and increased displacement. Remember, FAST is part of the COMP PERF GROUP which includes Comp Cams and RHS. Their products support each other.


Here are couple of items I did get clarified.

PULLEY WASHER/ALIGNMENT

– the pulley is ‘offset’ BY THE FACTORY. Our included spacer actually LINES UP the pulley setup. This is covered in the instruction sheet.

VACUUM NIPPLE

On the nipple; the LS3 camaro has a new nipple. In the short term, we INCLUDED the hose he mentions. We have already tooled the correct Camaro nipple and it will phase in once available.; keep in mind, this manifold was fully designed and in production before the 2010 Camaro even existed.

[CamaroSpike23]

intakes like the FAST LSXR one are not made for stock motors. they are designed for motors that have been cammed, sprayed, blown, etc.

It is designed so that the individual runners can be modified for a specific length for a specific motor application. now if someone who has one already went and trimmed the runners here and there and did repeated dyno runs to see any difference on a stock motor, that might be worthwhile, but the intake as is on a stock vehicle is not worth it unless you plan some serious mods in the near future.

As stated above-We gained virtually nothing on the L-99.

BTW-We are making 363RWHP and 382RWTQ out of this L-99.

This car runs strong at the track,we just want to see when it stops making power with all stock internals...Looks like we are there.

If the Intake does not help him on friday night,I am taking it off and installing it on my LS3 head 427 Camaro that is currently at 560rwhp with stock LPE PORTED Intake.

Andy,

I think you are right, around 360rwhp and around 380rwtq (dynojet SAE corrected) is where the stock internals just aren`t going to allow any more power on the L99. I just put down 362rwhp and 381rwtq (dynojet SAE cor.) w/ ARH 1 7/8`s cats, stock mufflers, your race intake and a tune. The Camshaft is the restriction past that. My tuner basicly told me that as well and I had not even asked him, he said it just won`t make any more power past that point from what he`s seen so far.

Exactly..Been there done that!

Andy

BTW-We yanked that Intake off and made same power.....I got a used piece of plastic I need to get rid of now

[2010_5thgen]

im doing a cam package on mine. so will this intake manifold be good for it or not?
