From what I seen it looks like a pyramid with rounded corners. I was told that it is used to decrease volume size right under the TB.

There are a variety of different designs - pyramid, turtle, ridged, etc. Essentially it is a piece of billet aluminum or steel that screws into the bottom of the M1 manifold. It is supposed to help direct incoming air to the runners, instead of hitting the flat bottom and then going down. The idea is to reduce incoming air turbulence. Some people say they work, others say different.

The turtle does two things. One it arguably directs or deflects the air towards the runners. Two it reduces the volume of the plenum which should increase your bottom end.

I just intalled the M1 2bbl myself the other day and after the computer re-learns it my bottome-end on my 5.2L suffered a little bit, and I mean very little, but it was well made up for in the midto top end power. It has a strong pull after 2500 rpms over that dam beer barrel intake. I dont think the turtle wil help out anyway unless maybe you are running boost.

The turtle is for those NOT running boost. Plenum volume is not all that criticl with boost
How bad can the kegger be when there are trucks using easily modified keggers and running in the 12's?

Yah and I can extrude hone an M1 and I want to see the stock beer barrel run in the 10s. The M1 will handle that. I have seen more performance gains out of a stock M1 than a moddified beer barrel.

That's nice but it doesn't look like your or 99% of Dakota owners will ever see 10's. You can't justify an M1 like that. It's cool, impressive to some people and gives good top end. Personally, I think that most people find more bottom end desirable in a truck. However, you certainly don't "need" an M1 to get your truck into the 14's or even 12's.

I realize that, and your point taken. I was merely saying I am just using the M1 for later down the road and even if you cut the beer barrel it doent have its tunnel ram effect, which is why bottom end power is in our trucks. When you moddify it you have just eleiminated this effect and now have more mid-top end like the M1. I not bashing the beer barrel, but to me its more practical for the M1s use for all the modding of the barrel you will have to do. IMO of course.

Yes, it probably all boils down to whether or not you are willing to do the work and what your budget is. You regain some of the low end, that you lost by shortening the runners, by filling or using a turtle.
There is nothing wrong with using the M1, in fact I have a 4bbl version that I plan on using as a 4bbl. I just think the stock manifold is grossly under-rated and mostly by people that just heard it on the internet.

Nice truck! I am almost finished with my filling in job on my intake. I made a "turtle"(didn't know it had a name before now) that fits to my plenum plate out of aluminum. Kind of looks like this:
I know it looks like a pair of @ss cheeks here, but it is a little more elaborate than this.
If it ain't broke, fix it til it is.

Honestly though, I have been driving my truck and I can hardly tell I lost any low-end....so even If i got the turtle, how would I mount the sucker up?

I cant believe your still on this.....
Are you going to go out and buy a throttle body spacer? Magnetic Fuel particle separator? Tornado? $10 ea spark plugs? Miracle oil additives?
Like I said before, that ocean front arizona property is up for sale?
Look at your stock manifold....it does awesome in the idle - 2000 rpm range. Why? Intake runner length and size. it has TONS of plenum space, yet it does well. Then look at the M1....hardly any space right? This would mean according to N56629 that the M1 should kick the stock manifolds ass in the low end. Hmmmmmmm.
Don't waste your money. And stop peddling junk.

No because it doesnt have the design of the tunnel ram system like the beer barrel does.
Its all about physics young watson and I dont believe in the tornado and tb spacer because those dont have dyno numbers reported. I have heard that their is numbers on the turtle but I havent really wasted my time looking at one considering I have enough low end to need 3rd gear to grip most of times when I nail it from a stop. Even with the M1 intake but hey who cares??

WTF, since I have a turtle in an M1, it's already obvious you don't know what you are talking about. It was originally installed and used by someone that actually does race and actually does know something.
"This would mean according to N56629 that the M1 should kick the stock manifolds ass in the low end."
Don't put words in my mouth because I never said that. You are comparing apples and oranges. The M1 has shorter runner length than the stock manifold. Some people claim that they didn't lose any bottom end but the majority admit that they did. If you are looking for more top end the M1 is certainly the way to go. In order to take advantage of the M1 you need to go to much lower gearing.
The stock manifold can readily be modified to get the same results that the majority of M1 owners now get.
Using a turtle to change the volume of a manifold makes as much sense as changing the runner length. It is not snake oil, it is basic intake manifold theory.
