Single plane intakes Ive been reading up on single plane intake and all. My question is what do you guys running them use for an iac? Just crack the blades a **** hair to let it breath or drill a hole?

Verdad Gallardo According to YB, the stock breadbox is a paper weight and you should have a single plane. Average ET of poster: mid 8s
According to LS1tech, the stock intake is good to 7s no issue what so ever and anyone who swaps out to a single plane is a retard who doesn't know anything. Average ET of poster: mid 12s

That settles it then. :lol 
I would say, with no personal experience of course, that if you're exceeding the stock pcm rpm wise or map wise then its a decent rule of thumb you would benefit from a single plane.

The LT1 intake is a good intake for a factory made item, surprisingly. It offers good performance over a wide rpm range. Is it the best? no. But if a better one is needed is a different story.

combination will really drive the answer. i have run 8.90's at 3500lbs with a lt4 intake setup with boost. with a n2o combination you better be running a fogger if you want to run those number with a factory intake. on a single plane you can get some killer plate setups. n/a setup would need to see a lot of rpm and/or ci to need more than a good ported stock intake.

Shownomercy just can't be bothered with reasonable discussion and has to try to attribute made up bullshit to other posters rather than actually discuss anything.
For most of us building street/strip cars we need not be concerned with single planes and such, there are better ways to spend the coin. If I were building a 8 second racecar then it is something you need to be looking at.

For more fun search what Ed has said about single planes in the past.
This is not to say there is no point where they are good, it is more to say the benefits are overstated and the point at which they becomes "necessary" is a lot faster than most people are looking to go.

Reasonable discussion on tech, in the LT1 section? Yea, good one. Coming from the guy who just wants to nut hug AI and trash LE.
There is a reason a front feeder intake has a limit on how much you can spray via a plate/nozzle before the rear cylinders start to show limits. A single plane gets you a lot better distribution and the ability to run a spacer for more plenum volume. Can't really do that with a stocker. Ed runs a super stock class, not sure how that applies to FI or N20 stuff.
For forced induction stuff I do not think its as bad of an issue but, I like to think my intake allows for better cyl distribution. Less restriction in the intake tract means a more efficient turbo so I will take my large TB and ported single plane over a LT1 setup. Then again, all the stock 5.3 guys run truck front feeder intakes and no issues going rather quick/fast.

Few years ago there was a guy who specifically stated he wished he hadn't spent the money, made like 20hp peak more but lost so much over such a broad range below 6500 that it didn't pay off.
There ARE definitely advantages especially with something like nitrous distribution, but this isn't something the average guy with a street strip car needs to consider.

You know how much easier ram air would be with a top mount TB? Well, of course you do. LOL.
I wanted one, don't get me wrong. But, I couldn't justify the expense only to loose daily driver friendly low rpm tq to gain 15-20 hp over 5.5K with my 6400 rev limit.
