Well hard to compare, when theres nothing to compare to unless its a stocker. Unless you know of another one???? Post that co. intead of posting wise remarks.
You can always make your own. Then anyone would know just what its worth. Time
Re: FIRST PICS!! New Tundra intake manifold, dual plenum
If you did your homework you would find that there are no other manifolds available to compare too. I think that was Gadget's point. Cowboy has taken the time ,trouble and considerable expense to offer this option to serious enthusiasts. You cannot compare a custom hand-made part to a mass produced Chevy manifold from a discount supplier.
If you want to make serious power ,this part is for you--if not--at least appreciate it.
Re: FIRST PICS!! New Tundra intake manifold, dual plenum
EXACTLY!!!
If there was a sufficent volume being sold then production costs would drop substaintially. However for a very limited production hand made unit, the cost I think is very reasonable.
Re: FIRST PICS!! New Tundra intake manifold, dual plenum
What intakes were flowed? Off what year?
Are there differences in intakes? I know mine on my 06 are plastic. Are they all plastic? Were there any differences through the years?
Has anybody ever flowed the heads? I'd love to see those figures.
How big are the intake and exhaust valves?
Re: FIRST PICS!! New Tundra intake manifold, dual plenum
Do you think we can get the documentation on what method was used for measuring the flow on the manifolds. Perhaps we can independently do similar tests on the stock manifold and perhaps mild porting on the stock manifold. If we can use the same method then the grain is valid. The independent tests will demonstrate the validity and reliability of the manifold. The initial production of this manifold is beautiful. How do we know the workmanship of production quality will be consistant? I have seen some interesting pictures on the net about production quality. On the other hand, not knowing the true grain on hp. The manifold is about $1,800, standalone is about $2,400 plus $1,000 install and tune. Throttle body and other misc parts like cables, wires ($500) and most importantly how would this manifold fit and behave on a live engine is still unknown. If power to be grain, what part of the power band it will be?
If we can do the math, its about $5,700. So the price of the manifold is just the initial cost, not the total cost. If we can port the stock manifold and say it increase 10% to 15% for about few hundred dollars is well worth it. What do u guys think?

Re: FIRST PICS!! New Tundra intake manifold, dual plenum
A standalone is not required when a stock TB is used. If the IAC is retained, and the stock TB used, then I'm not sure why a standalone would be needed. We are currently working with Rob Welsh, however to bring a 100% plug n' play harness to market that adapts an Supra MKIV TT AEM EMS to the 2uz-fe. It is in process this week, and testing will begin soon.
It should be said that this manifold is not for everyone. If you are on a budget, then there are other ways to make gains besides this manifold. It should be said that this manifold is a gateway to more HP, and not so much a direct cause of it. Most folks, sadly, don't understand what that means. This manifold will only give you, what you put into it. No one can expect massive HP gains with it alone when the rest of the motor is stock. Add a supercharger, cams, and headers, and things will be different.
The differences between the stock manifold and our manifold are apparent. Porting the stock manifold efectively would be a hell of an undertaking and still would solve the root problem, that being the 15 inches of runners. Our runners are only 3.5inches in length, and a plenum volume of approximately 6 liters, so it would stand to reason that our manifold flows tons more.

I would not call 27% increase flow as tons more. All those grain are theoritical not actual grain. Its basically a quarter more flow. I think the community would like to duplicate the test and to validate how you come to the conclussion of a quarter increase in air flow. I think disclosing the method of testing is essential to the community. I personally would like to duplicate the testing and flow numbers.
Budget is one thing.. smart money is another. Besides the money issue, I would imagine down time would be quite long. Since not too many tuner have any experience with Tundra. So most tuners would tune and learn and so on.

Re: FIRST PICS!! New Tundra intake manifold, dual plenum
I guess you just can't find any redeeming qualities, can you David Phan?
And all those "grains" are ACTUAL flow gains, not theoretical. That was the purpose of flowing the damn thing. The conclusion to how we got 30% more airflow was the formula VE x RPM x CI / 3456 = CFM. Once you have the values, you can find out your airflow at a given RPM, in this case 4500rpm. FWIW, 30% gains, are 30% more than any other 2uz intake produced and available at any price.
Point blank, the manifold was flowed back to back against the stock manifold, and found to flow an average of 30% more. The tests have been performed by Boyd Automotive, a motor building facility, in Orlando, Florida.
My advice to you, simply, is not to buy one. However, if you would like one to perform duplicate testing, I will draw up you invoice tonight.
