wouldn't you think that this 102mm would be way to big for your 346ci motor? I can understand using these on your 400+ ci motors, but this gets to the point where bigger inst always better.

You dont have to run a 102mm TB. Ive been running a FAST LS3 102mm intake with a 90mm TB for a while now. So you can still run a 90/92mm throttle body on it.

Yes it will clear an Fbody with no problem. We did the test fitment for fast on these intakes.

I know you don't have to run 102mm on the intake, but since you have the ls3 intake you have the rectangular style heads which means you have a 4+ inch bore to accommodate the extra air intake that a 346 may not be able to handle. That's all I'm saying there is no doubt that this intake will work extreme good for some applications, but when does bigger become to much?

so should I sell the 92 intake and throttle body and get this?

Depends how much is 3-4 rwhp worth to you?

right now it just has a lid, arh 1 7/8 headers with cats and magnaflow catback. every piece of UMI suspension available. I might also get a thunder racing's old man cam.

I wonder if FAST did their homework, and fixed the MAP sensor fittment issues?

Dennis@SpectacleSolutions

what fitment issue? there are two spots for the MAP sensor.... front and rear

Looks like a thing of beauty. Should have no problem fitting in an F-body, now this one I'm not sure about:

i wanna see a group buy on this thing to see how good a deal can be had.

Yes, there are not only two places for the MAP but there is a hold down!!!

On the 92 the rear MAP hole was slightly big for the MAP sensor, it would wiggle around and cause lean codes. People fixed this by making a bracket to hold it down tight, or use RTV to seal it tight, or use a piece of fuel line to make the MAP sensor fit snug. I'll find some threads on the issue.

I agree, when is bigger always better? Some people do not always want the biggest, baddest setup, but something more refined, and more efficient for driving around town all day. Throw one of these intakes and a set of 1 7/8 headers on an otherwise stock 346 Ls1 and IMO, that would be a total dog down low. Who wants a car that drives like a mustang?

I can see the potential for a bigger cubed motor like mentioned above or at least a nice sized cam and some ported and flowed heads on top the 346 but honestly, when is the size going to stop growing? WHEN WILL IT END?

Options now once all 90/92mm are sold will be Ls6 78mm or just all the way to 102mm? Seems like a big gap to have to jump if you dont want to get into single planes and sheet metal, etc.

You can still use the 92mm TB so you will still have the same airflow. Also if you keep a smaller MAF and Lid it wont be able to flow any more air.

We are going to be offering a competitively priced 102mm TB and intake combination as soon as test results are in. Anyone who has seen the L92 results will know why.

I don't really understand why...I'm assuming you are referring to the few posts that have popped up where people weren't getting gains with the FAST 102 for L92/LS3 heads.

Since this is replacing the last of the 90/92 units out there, what other option is there for cathedral port guys? The 78mm piece? Or are you going to stop carrying their line altogether? If this doesn't live up to your standards, it isn't like there will still be 92mm FAST intakes out there for sale (except by those that already bought them while they were still being manufactured).

True, it was meant for guys who are thinking they will gain over their current 92 setup.
