Reason for switching to a carb intake??
Reason for switching to a carb intake?? Why are the big boost guys going with a carb intake and a sheet metal elbow? Do the stock intakes not hold up under high pressure? Better flow out of the carb intake?
It looks kick *** but that alone will not justify me getting that set up.

from what im told, its not a issue of flow restriction, but a matter of getting a more even amount of air into each cyl.
something about the air is shoved into the front and it hits the back of the intake so the rear cyls are leaner, then the front ones....
i dont know much more then that.. its just "stuff i read online", not "stuff i can afford to do" lol.
as much as people worry about the plastic intakes, i have yet to hear about someone breaking one due to boost.... now nitrous backfires, yes... boost, no.

I'm pretty sure it has to do with getting even air flow to each cylinder. The air distribution with the carb intakes is much more eqaul than the lsx intakes, ie air coming in from the top is better than it coming in on the front of the intake stuffing the back 2 cylinders, which can cause them to run lean and pop. On top of that, the carb intakes are also suppose to flow better, so it's a win/win for the big HP guys.

Ive said it before though. I'm not convinced I have gained any huge amounts of power by fitting one though.
it feels stronger in the low-mid range, and did require a fair bit more fuel in these areas.
But up top....I had to do very little to maintain the same AFR's as per LS6/Stock TB intake.
Dont have access to a dyno, so cant give any numerical evidence for power etc.
carb intakes are still nowhere near perfect distribution. they just move the problem around more. i think alot of the gains people get are from the short runners and reduced plenum size.
If you have an odd problem, like needing to intercool a whipple twinscrew on a truck motor, the carb intake can eliminate a lot of clearance issues. Or maybe that's just me?
I would really like to see some testing comparing the two. For me I am running the LS6 on my 427 and plan to keep it. I might switch to a smoother flowing TB when the procharger goes back on tho.

80% of the time you create a clearance issuse by going the carb style . not the other way around esp if its an f-body you have the cowl to deal with and some triming is required unless you drop the engine down a bit
i would like to see someone do an egt and wideband test per cly and compare back to back with a stock style vs carb style to see if the "rumors" are true that air flow is more complete with a carb style.
kp pointed out in the thread i started that even by turning around the mainfold it still didnt change the #7 problem... anyone ??????
as of now after speaking with many many many builders from what i have now gathered there are as many theories about the intakes differeances as there are builders. i bought into the myth and went carb style. i could have easily used any intake i wanted but i choose what "i" thought would work the best, time will tell.

Sometimes its easy to overanalyze purchases and decisions, especially expensive ones. With race cars there is usually more then one 'correct' way to achieve a goal, if you simply just like the way it looks or if you think it will work for you just use it and why worry what other people have to think. In the big picture its a small part of the overall combination.
I feel that there is very little proof that the carb intakes improve flow distribution. I know that several people have made near 1khp with an ls6 intake. This is why I gave the original poster one isolated instance in which there is a real need for a carb intake. It may be relevant-- it may not.
